Dynamic selecting a table

I want to write a dynamic Query to select a Column called sFirstName from
different table based on Name column which exists in all the table
The table name which I get from My process is with spaces So I need to
replace " "(Space) with ("_") underscore. I know this can be done using
execute sp_executesql @.sql... but Please advice if this can be done with a
Sql Statement
Declare @.sTemp_Name varchar(100)
Set @.sTemp_Name = replace('Complaint table' ,' ','_')
Select sFirstName from dbo. + @.sTemp_Name + where Name = 'Samay'
The above Code gives me an Error as " Incorrect syntax near '+'. "
Please advice
Thanks
kritiHi,
The only solution for this is using Dynamic SQL using either sp_executesql
or EXEC

Dynamic Select/Update Statement Possible?

Would it be possible to retrieve a "dynamically" named field from a table by using an input parameter?

For example, if a table has fields named Semester1, Semester2, Semester3, Semester4, and I was lazy and only wanted to create one stored procedure for all semesters could I do the following...

ALTER PROCEDURE u_sp_x
@.semester int
AS
Select Semester@.semester
From ThisTable

Just curious.

Thanks,
Steve HanzelmanThis might work..

alter procedure u_sp_x
@.semester int
as
select * from semester
where @.semester = 'semester 1'|||You CAN do just about anything. Dynamic SQL statements would be required here, or a UNION query or complicated WHERE clause. But whether you SHOULD do it is another think entirely. Dynamic SQL statements are a pain in the butt, and should be avoided, and thus are definitely more for masochistic DBAs than lazy DBAs.

Your problem, as is often the case, is that you are having to code around a deficiency in the design of your tables. You should have a table that stores each Semester's value as a separate record. Then your application will also be easily adaptable to situations where three or five semesters are allowed, or half-semesters, or quarters, or whatever.|||Blindman,
I agree re: the design of the tables/database. Unfortunately, it is one that was inherited and belongs to an application that was purchased by my employer. Therein lies the rub...can't modify so I'm try to save a few steps.

Oh well, I'm guessing four procedures.

Thanks for the help.|||OK...

First, I have seen WAY too many slick apps that pretend to be cute..they are MAJOR pain to debug.

The smaller you make your sprocs, the better. And the less dynamic sql the better.

So with that said...the keys to the kingdom

USE Northwind
GO

CREATE PROC mySproc99 @.COLUMN_NAME sysname, @.TABLE_NAME sysname
AS
DECLARE @.sql varchar(8000)

SELECT @.sql = 'SELECT ' + @.COLUMN_NAME + ' FROM ' + @.TABLE_NAME

EXEC(@.sql)
GO

EXEC mySproc99 'ShipName','Orders'
GO

DROP PROC mySproc99
GO|||Brett proposing dynamic SQL?! :eek:

What's the weather forecast in Hell, today? ;)|||I was thinking this, but forgot...

Becareful out there...

And

Abandon all hope for ye who enter here...

Only dynamic sql I use is for admin purposes...never in an application

(Some would say some of my admin procedures amount to a mini mainframe application...but that a story for another margarita...COME ON 5:00!)

Dynamic Select Statement

please advice me with the below SQL Script
say,I have a cursor to Insert a records in the table if the below condition matches
samay
I have different tables
1. EMPLOYEE
ID Salary TableName
==================================
EMP1 25000 Nametable1
EMP3 15000 Nametable2
EMP19 15000 Nametable3
EMP5 10000 Nametable4
2.
Nametable1
ID Name
============================
EMP1 Samay
EMP2 Rahul
3.
Nametable2
ID Name
============================
EMP19 Samay
EMP29 Rahul
Now,
1. I want to get the TableName(@.TableName) from EMPLOYEE where salary = 15000
2. Select a Name from (@.TableName) table
where EMPLOYEE.ID = @.TableName.ID
Declare @.Name
Declare @.TableName
Declare @.ID
Set @.ID = (Select ID from EMPLOYEE where salary = 15000)
set @.TableName = (Select TableName from EMPLOYEE where salary = 15000 and ID = @.ID)
Set @.Name = (Select Name from @.TableName where ID = @.ID)
Now if I execute my script which has a cursor it give me an Error
Must declare the variable '@.TableName '. for Last line script
PLease advice me with this
1) you need to declare your vbls
2) Dynamic SQL means that you build a string (E.g., @.SQL below) which when all put together is a valid SQL Statement. Then you execute it via exec (@.SQL).
Declare @.SQL varchar(2000)
Declare @.TableName varchar(100)
Declare @.ID int
Set @.ID = (Select ID from EMPLOYEE where salary = 15000)
set @.TableName = (Select TableName from EMPLOYEE where salary = 15000 and ID = @.ID)
Set @.SQL = 'Select Name from ' + @.TableName + ' where ID =' + Str(@.ID)
exec (@.SQL)

|||Sorry - that was not clear from your original inquiry.
I can think of 3 way to accomplish this:
1) Use a temporary tbl
if Object_ID('tempdb.dbo.##tmp') is not null
drop table ##tmp
Set @.SQL = 'Select top 1 Name as test into ##tmp from ' + @.TableName + ' where ID =' + Str(@.ID)
exec (@.SQL)
set @.Name = (select test from ##tmp)
print @.Name
2) Combine your SELECT and INSERT into a single "dynamic" SQL, by doing INSERT after your SELECT.
Set @.SQL = ' declare @.name varchar(100) Select top 1 Name from ' + @.TableName + ' where ID =' + Str(@.ID) ' + ' -- here goes your insert statement or a call to SP which does the insert'
3) Or just combine INSERT and SELECT into a single query
Set @.SQL = 'insert into NameTable(Name) from Select top 1 Name from ' + @.TableName + ' where ID =' + Str(@.ID)
exec (@.sql)
Hopefully, one of these 3 ideas meets your needs...

Dynamic Select Statement

please advice me with the below SQL Script
say,I have a cursor to Insert a records in the table if the below condition
matches
samay
I have different tables
1. EMPLOYEE
ID Salary TableName
==================================
EMP1 25000 Nametable1
EMP3 15000 Nametable2
EMP19 15000 Nametable3
EMP5 10000 Nametable4
2.
Nametable1
ID Name
============================
EMP1 Samay
EMP2 Rahul
3.
Nametable2
ID Name
============================
EMP19 Samay
EMP29 Rahul
Now,
1. I want to get the TableName(@.TableName) from EMPLOYEE where salary = 1500
0
2. Select a Name from (@.TableName) table
where EMPLOYEE.ID = @.TableName.ID
Declare @.Name
Declare @.TableName
Declare @.ID
Set @.ID = (Select ID from EMPLOYEE where salary = 15000)
set @.TableName = (Select TableName from EMPLOYEE where salary = 15000 and ID
= @.ID)
Set @.Name = (Select Name from @.TableName where ID = @.ID)
Now if I execute my script which has a cursor it give me an Error
Must declare the variable '@.TableName '. for Last line script
PLease advice me with this1) you need to declare your vbls
2) Dynamic SQL means that you build a string (E.g., @.SQL below) which when a
ll put together is a valid SQL Statement. Then you execute it via exec (@.SQ
L).
Declare @.SQL varchar(2000)
Declare @.TableName varchar(100)
Declare @.ID int
Set @.ID = (Select ID from EMPLOYEE where salary = 15000)
set @.TableName = (Select TableName from EMPLOYEE where salary = 15000 and ID
= @.ID)
Set @.SQL = 'Select Name from ' + @.TableName + ' where ID =' + Str(@.ID)
exec (@.SQL)

I can think of 3 way to accomplish this:
1) Use a temporary tbl
if Object_ID('tempdb.dbo.##tmp') is not null
drop table ##tmp
Set @.SQL = 'Select top 1 Name as test into ##tmp from ' + @.TableName + '
where ID =' + Str(@.ID)
exec (@.SQL)
set @.Name = (select test from ##tmp)
print @.Name
2) Combine your SELECT and INSERT into a single "dynamic" SQL, by doing INSE
RT after your SELECT.
Set @.SQL = ' declare @.name varchar(100) Select top 1 Name from ' + @.Table
Name + ' where ID =' + Str(@.ID) ' + ' -- here goes your insert statement
or a call to SP which does the insert'
3) Or just combine INSERT and SELECT into a single query
Set @.SQL = 'insert into NameTable(Name) from Select top 1 Name from ' + @.T
ableName + ' where ID =' + Str(@.ID)
exec (@.sql)
Hopefully, one of these 3 ideas meets your needs...

After executing the above @.SQL, you will end up with a tmp table ##TempDelet
e, which will have a single column, named eID. From here you treat your temp
table, just like any other table.
e.g.,
Select * from ##tempDelete
then change your last SET statement to:
Set @. Name = (select eID from ##TEMPDelete)

EXECUTE (@.Command)You don't have to have the fields showing in the Designer to use them. You
can set the source of the textboxes to =Fields!<your field name>.Value. You
can also use the IsMissing property of the Field object to determine if the
stored procedure has returned the field or not. Finally, please not that
multiple select statements are not supported in RS; only the first is used.

Hope this helps.

Dynamic Select in MSSQL

Hi folks,
I have a problem migrating from Oracle to MSSQL the statement:
stmt2 := 'Select substr('||tabc||',1,50) from '||tabn||'
OPEN cur2 FOR stmt2;

How can I to perform this dynamic select into MSQL ??

Thanks 4 your helpI partially solved with:

Exec ('select substring('+@.chvCol+',1,50) from ' + @.chvTable + .....)

with

DECLARE @.chvTable sysname, @.chvCol sysname

Dynamic SELECT Command in SqlDataSource

I have a GridView (that uses SqlDataSource1) and a Dropdownlist. Depending upon the value selected on the DropDownList I need to select different stored procedures for the gridview. The problem is that I can do it without taking SqlDataSource1 by using DataSet or DataTable. But, I need to Use SQLDataSource1 for easy way of Header SORTING. So, is there any way to change the SQLDatasource1.SELECT Command dynamically. So that, I can use different queries for the Single DataGrid.

I have attached the sample code of the SqlDataSource1 I'm using. I need to change the Command i.e.SelectCommand="usp_reports_shortages" to"usp_reports_shortagesbyID" and"usp_reports_shortagesbyDate"

depending on the value selected in the dropdownlist. So, is there any way to do this??
<asp:SqlDataSourceID="SqlDataSource1"runat="server"ConnectionString="<%$ConnectionStrings:TESTDrivercommunication%>"

SelectCommand="usp_reports_shortages"SelectCommandType="StoredProcedure">

<SelectParameters>

<asp:ControlParameterControlID="lblDriver"Name="date1"PropertyName="Text"Type="DateTime"/>

<asp:ControlParameterControlID="lblTODate"Name="date2"PropertyName="Text"Type="DateTime"/>

<asp:ControlParameterControlID="DDlDriver"Name="driver"PropertyName="SelectedValue"

Type="Int32"/>

<asp:SessionParameterName="week"SessionField="s_week"Type="DateTime"/>

</SelectParameters>

</asp:SqlDataSource>

Numerous ways.

Change the value in the dropdown's selectedindex changed event.

Change it in SqlDatasource's selecting event.

Change the select command to an if. "IF @.DDlDriver=1 THEN EXECusp_reports_shortages @.date1,@.date2,@.weekIF @.DDlDriver=2 THEN EXEC usp_reports_shortagesbyID @.date1,@.date2,@.week IF @.DDlDriver=3 THEN EXECusp_reports_shortagesbyDate @.date1,@.date2,@.week".

Make a stored procedure that takes all 4 paramters and encapsulates the IF's.

Dynamic report parameters

hells
Does anyone know a way to set up a report with two parameters that the
user can select, where one parameter's populated with data depending on
what's selected in the other parameter?
I'm doing a report of some questionnaire data. I want to let the user
select a question, then select one of the possible responses to that
question. The report will then display answers to *all* questions from
people that gave the selected response to the selected question.
I thought maybe I could use subreports to do this but can't seem to get
that working.
Help much appreciated!
NickTake a look at cascading parameters described here:

Dynamic query: EXEC - Need to get a return value from query

I use dynamic SELECT statement trying to achive the followng:

DECLARE @.table varchar(50)

DECLARE @.ColumnA varchar(50)

DECLARE @.Result float

SET @.table = 'TABLE_A'

SET @.ColumnA = 'COLUMN_1'

SET @.SQL = ' SELECT @.Result = (SUM((' + @.ColumnA + ' )) FROM ' + @.table

EXEC (@.SQL)

I need to assign the outcome of this statement to the @.Result variable. It does not work because of different contexts for @.Result. It would run if I do

SET @.SQL = 'DECLARE @.Result float '

SET @.SQL = @.SQL + ' SELECT @.Result = (SUM((' + @.ColumnA + ' )) FROM ' + @.table

But in this case @.Result is not 'visible' outside EXEC statement.

One way to solve this is to use INSERT statement into temp table and then read result from the temp table.

Are there any more elegant solutions?

Thanks!

Sorry, but the code in EXEC() is considered to be its own batch, so you will need to persist it in a table, and temp tables are usually used for this. BTW, what did you need to do with the @.Result value? You may be able to put that in the same EXEC() code.

Thanks, Dean

There are different ways to execute dynamic sql. The one that you need is sp_execsql. It allows you to declare parameters -- even output parameters. A key to remember is that an output parameter must be declared as output twice, in much the same way that an output parameter is declared both inside a stored procedure and on the exec line.

Your code should look like:

Declare @.result float

SET @.SQL = @.SQL + ' SELECT @.Result = (SUM((' + @.ColumnA + ' )) FROM ' + @.table

exec sp_execsql @.sql, N' @.Result float Output', @.Result output

The command wants NVarchar() parameters. Make sure @.sql is declared NVarchar() and include the N on the literal declaring the parameter. You can have multiple parameters if needed.

Dynamic Query question

I am using the BOL walkthrough and have come to the Dynamic Query section.
I type in the following into the generic query builder...
="SELECT FirstName, LastName, Title FROM Employee" &
IIf(Parameters!Department.Value = 0,""," WHERE (DepartmentID = " &
Parameters!Department.Value & ")") & " ORDER BY LastName"
But it does not work... Can anyone please assist?If you mean that the fields list is not populated, yes, for query
expressions you'll need to populate the fields list manually. Another
approach is to first type in the static version of the query (select
FirstName, LastName, Title from Employee), run the query, switch to layout
pane, switch back to data pane, and then replace the static version with the
expression-based version you have below. You will then see the fields list.

Dynamic Query

I use IIF in the dynamic query to dynamically change the Select, Group By, and Order By statements.

In the table grouping properties, i also use IIF to change the grouping Field.

There are no errors, the report processes OK, but the report is not grouped or shows any Field values for which i have to use dynamic query. What could be the problem? Can anybody help please.

Thanks

Can you post the dynamic query you are using, as well as the group expression? Also if you enable tracing on the database side, is the query being executed correct?|||

Thank you for answering to my problem. I did get over it after much trying. The dynamic query looks like this:

="SELECT SUM(BASE_UNIT) AS BASE_UNIT "
& IIF(Parameters!Type.Value = "Location", ", Location", IIF(Parameters!Type.Value = "Admit_Source", ", Admit_Source", ", Provider_Name")) &
" as grouping FROM TBL_EOM
WHERE (MONTH(ENTRY_DATETIME) =@.RepMonth) AND (YEAR(ENTRY_DATETIME) = @.RepYear)" &
IIF(Parameters!Pract.Value = "*** ALL ***", " ", " AND (NAME = @.Prac) ") &
" GROUP BY Provider_Name, NAME" & IIF(Parameters!Type.Value = "Location", ", Location", IIF(Parameters!Type.Value = "Admit_Source", ", Admit_Source", " "))

In layout view i have this strig for field, grouping and sorting:

IIF(Parameters!Type.Value <> "Provider", Fields!grouping.Value, " ")

Thank you

Dynamic query

I use Dynamic Query:
="Select dbo.UserList.UserID FROM dbo.UserList
WHERE dbo.UserList.IncidentID = " & Parameters!IncidentID.Value
While I built the solution I had:
The expression for the query ?DataSource2? contains an error: [BC30648]
String constants must end with a double quote.
Tried to play with quotes - nothing helps. What can be wrong?
Thank you in advance.I assume that IncidentID is a varchar or something like that. So you need to
enclose your parameter is single quotes. When figuring this out I usually
have a textbox that I set the expression to so I can see the result. What
you want is this:
="Select dbo.UserList.UserID FROM dbo.UserList WHERE dbo.UserList.IncidentID
= '" & Parameters!IncidentID.Value & "'"

Dynamic query

Hello!
I tryed the example from Reporting Services Books Online but it didn't work.
I copied ="SELECT FirstName, LastName, Title FROM Employee" &
IIf(Parameters!Department.Value = 0,""," WHERE (DepartmentID = " &
Parameters!Department.Value & ")") & " ORDER BY LastName"
in generic query designer and when I ran the report I received the following
error: Cannot use empty object or column names. Use a single space if
necessary.If department ID is a string then you need to embed it in single quotes. I
suggest doing the following, create a textbox and assign expression to it so
you can see whether you have created it correctly.

Dynamic PIVOT quey challange

Hi

I have following Table A In which values of LotNo field is not fixed so we cannot write these values to our PIVOT clause in Select statement. Now can any one provide me sucha a query which can generate this PIVOT result in Table B. Not there is a distnict list of Lotno. is availble from a view.

Table A

LotNo.

Pcs

Wt.

12

200

12.212

13

21

16.214

17

23

21.211

18

27

32.212

Table B

LotNo

12

13

17

18

Pcs

200

21

23

27

Weight

12.212

16.214

21.211

32.212

So I want to write a select query wth PIVOT clause which takes Lotno. which is not fixed values (As given in Adventureworks sample). ThisLotno. is based on distinct values from a list of LotNo. which is availble in another Table. Please anyone help me.

Nilkanth Desai

You can use the following querys

1. Using UNION

SELECT
'Pcs',
*
FROM
(SELECT LotNo,Pcs from TableA) Master
PIVOT
(
Sum(Pcs) for LotNo in ([12],[13],[17],[18])
) AS pvt2
Union All
SELECT
'Wt',
*
FROM
(SELECT LotNo,Wt from TableA) Master
PIVOT
(
Sum(Wt) for LotNo in ([12],[13],[17],[18])
) AS pvt2

2. Merging data into Single Table then applying the Pivot

Declare @.Table Table
(
LotNo int,
Type varchar(10),
Value float
)

Insert Into @.Table Select Lotno,'Pcs', Pcs From TableA;
Insert Into @.Table Select LotNo,'Wt', Wt From TableA;

SELECT
*
FROM
(SELECT LotNo,Type,Value from @.Table) Master
PIVOT
(
Sum(Value) for LotNo in ([12],[13],[17],[18])
) AS pvt2

To generate this query dynamically you can see my earlier post http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1006316&SiteID=1

Here you go:

-- Create a Temporary Table holding all Values As LotNo, Group, Value
SELECT LotNo AS LotNo, 'Pcs' as Grp, Pcs as Value INTO #T1 FROM TableA
UNION
SELECT LotNo AS LotNo, 'Weight' as Grp, Weight as Value FROM TableA;

-- Declare a Table holding all Values of LotNo
DECLARE @.T2 AS TABLE(LotNo INT);
INSERT INTO @.T2 SELECT DISTINCT LotNo FROM #T1;

-- Construct the Columns for the SELECT and PIVOT-Clause
DECLARE
@.cols AS NVARCHAR(MAX),
@.lotno AS INT,
@.sql AS NVARCHAR(MAX);

SET @.lotno = (SELECT MIN(LotNo) FROM @.T2);
SET @.cols = '';
WHILE @.lotno IS NOT NULL
BEGIN
SET @.cols = @.cols + ', ' + QUOTENAME(@.lotno)
SET @.lotno = (SELECT MIN(LotNo) FROM @.T2 WHERE LotNo > @.lotno)
END
SET @.cols = SUBSTRING(@.cols, 3, LEN(@.cols));

-- Construct the SQL Statement
SET @.sql = 'SELECT Grp, ' + @.cols + '
FROM #T1
PIVOT(MAX(Value)
FOR LotNo IN (' + @.cols + ')) AS P'

-- Run it

Dynamic Parameters and using an "All" Value

I have a report that I need to create a parameter of Territories which I can
do with the following Data set...
Territories>>
Select Name
From dbo.territory
and
Contacts>>
SELECT TER.Name AS Territory, CAST(CON.ContactId AS varchar(36)) AS
ContactID, CON.FirstName, CON.LastName, CON.JobTitle, CAD.Line1, CAD.City,
CAD.StateOrProvince, CAD.PostalCode, CON.Telephone1 AS
businessphone, CON.MobilePhone, CON.Telephone3 AS rangephone,
CAST(ACT.AccountId AS varchar(36)) AS AccountID,
ACT.Name AS companyname, CAD.StateOrProvince AS company_stateorprovince
FROM ContactBase CON LEFT OUTER JOIN
CustomerAddressBase CAD ON CON.ContactId = CAD.ParentId AND CAD.AddressNumber = 1 LEFT OUTER JOIN
Account ACT ON CON.AccountId = ACT.AccountId LEFT
OUTER JOIN
CustomerAddressBase CAA ON ACT.AccountId = CAD.ParentId AND CAD.AddressNumber = 2 LEFT OUTER JOIN
TerritoryBase TER ON ACT.TerritoryId = TER.TerritoryId
WHERE (TER.Name IN (@.Territories))
ORDER BY TER.Name, CAD.StateOrProvince, ACT.Name, CON.LastName
I cannot create an All value and use it in the Parameters, for my parameters
values I was doing non Query and setting them to the name, but for All I
tried Northeast,Southest,West. That does not error out, it just doesn't
return any data. The other values work. Very Bizarre.
Any ideas of what I can do? The territory table uses GUIDs as IDs, So I
cannot easily create an integer which could solve the issue.Hi!
We had the same problem but did this.
In your territories select case do the following:
Select '%' as 'Name', 'All' as 'Label'
UNION
Select Name, Name as 'Label'
From dbo.territory and Contacts
This would give you a table looking like
Name Label
% All
Ottawa Ottawa
etc etc
The you would change the dataset statement to :
WHERE (TER.Name LIKE (@.Territories))
Hope this helps,
