Dynamic IN clause

I have a "can this be done" question...
I currently have a stored procedure that builds a string into a SQL
Statement and runs it.
This is an abreviated version as an example:
CREATE PROCEDURE stp_ClaimInfo
@.DFTAX# VARCHAR(12),
@.TCLAIM varchar(1000)
AS
BEGIN
DECLARE @.SQLstr varchar(4000)
set @.SQLstr = ' SELECT TMBR#, TCLAIM, SUM(TFLD16) AS TTFLD16 '
+ ' FROM tbl_claim_status'
+ ' WHERE DFTAX# = ''' + @.DFTAX# + ''''
+ ' AND TCLAIM IN (' + @.TCLAIM + ')'
+ ' GROUP BY TMBR#, TCLAIM'
exec(@.SQLstr)
END
And the run it as:
EXEC stp_ClaimInfo '86- 0291651','606900122,606900121,606800078'
The reason is because of the "IN" cluase. I need to pass it claim numbers,
but there can be one or more at a time, and different each time it is run.
In effect, the above query ends up as:
SELECT TMBR#, TCLAIM, SUM(TFLD16) AS TTFLD16
FROM tbl_claim_status
WHERE DFTAX# = '86-0291651'
AND TCLAIM IN (606900122,606900121,606800078)
GROUP BY TMBR#, TCLAIM
My question is how can I pass a dynamic list of values for the IN clause but
not have to write the statement as a string then execute it using
"exec(@.SQLstr)"? Can this be done?
-- AndrewUse the sp_executesql , this way you can add parameter definition. This
is an example i used in an SP with OUTPUT parameters.

SQL Server does not know what an array is, so no, you can't fool it into
believing this string is an array of ints. You can, however, encapsulate
splitting functionality off into another object.

AND ',' + @.TCLAIM + ',' LIKE '%,' + TCLAIM + ',%'
its not pretty though

Indeed, this can be done in a multitude of ways. For a quick start,
look at http://www.sommarskog.se/arrays-in-...ist-of-strings.
To see more ways, read the rest of the article.

sp_executesql does not change matters here. You would still have
to interpolate the list of values into the SQL string, you cannot
pass it as a parameter to sp_executesql.
The correct answer is that this is a task that you should not use
dynamic SQL at all for.

you use tbl- prfixes, # in names and what look like dat type prefixes
on column names. And put it in uppercase to make it harder to read. I
also loved seeing "fld_16" vague and it lets us know that you still
thinkin fields nad do not know about relational columns. You cannot
have a table named "_status" because a status is an atrribute not an
entity.
CREATE PROCEDURE GetClaimsList
(@.my_tax_nbr CHAR(10), @.p01 CHAR(9), @.p02 CHAR(9), .., @.p50 CHAR(9))
AS
SELECT member_nbr, claim_nbr SUM(fld_6) AS foobar_total
FROM Claims
WHERE df_tax_nbr = @.my_tax_nbr
AND claim_nbr IN (@.p01 CHAR(9), @.p02 CHAR(9), .. , @.p50 CHAR(9))
GROUP BY member_nbr, claim_nbr ;
Did you know that a T-SQL proc can have over 1000 parameters? Do you
eer need more than that? Wow! Compiled code that ports easily.|||dizzler,
Thank you for the reply, but I feel you missed the point of my question.

Thank you for the reply, but your suggestion just wouldn't work for the
situation I have as the incoming string is a comma deliminated list and
trying to break it apart outside the SQL Statement would reduce the
efficiency of the whole process. In a different situation, your suggestion
could prove to be a useful answer.
