How to pass a comma separated list to a stored procedure?

Question

So I have a Sybase stored proc that takes 1 parameter that\'s a comma separated list of strings and runs a query with in in an IN() clause:

CREATE PROCEDURE          


        

Answer 1

This is a little late, but I had this exact issue a while ago and I found a solution.

The trick is double quoting and then wrapping the whole string in quotes.

exec getSomething """John"",""Tom"",""Bob"",""Harry"""

Modify your proc to match the table entry to the string.

CREATE PROCEDURE getSomething @keyList varchar(4096)
AS
SELECT * FROM mytbl WHERE @keyList LIKE '%'+name+'%' 

I've had this in production since ASE 12.5; we're now on 15.0.3.

Regarding Kevin's idea of passing the parameter to a function that splits the text into a table, here's my implementation of that function from a few years back. Works a treat.

Splitting Text into Words in SQL

Answer 3

The problem with the calls like this: exec getSomething '"John","Tom"' is that it's treating '"John","Tom"' as a single string, it will only match an entry in the table that is '"John","Tom"'.

If you didn't want to use a temp table as in Paul's answer, then you could use dynamic sql. (Assumes v12+)

CREATE PROCEDURE getSomething @keyList varchar(4096)
AS
declare @sql varchar(4096)
select @sql = "SELECT * FROM mytbl WHERE name IN (" + @keyList +")"
exec(@sql)

You will need to ensure the items in @keylist have quotes around them, even if they are single values.

Answer 4

This is a quick and dirty method that may be useful:

select  * 
from    mytbl 
where   "," + ltrim(rtrim(@keylist)) + "," like "%," + ltrim(rtrim(name)) + ",%"

Answer 5

To touch on what @Abel provided, what helped me out was:

My purpose was to take what ever the end user inputted from SSRS and use that in my where clause as an In (SELECT) Obviously @ICD_VALUE_RPT would be commented out in my Dataset query.

DECLARE @ICD_VALUE_RPT VARCHAR(MAX) SET @ICD_VALUE_RPT = 'Value1, Value2'
DECLARE @ICD_VALUE_ARRAY XML SET @ICD_VALUE_ARRAY = CONCAT('<id>', REPLACE(REPLACE(@ICD_VALUE_RPT, ',', '</id>,<id>'),' ',''), '</id>')

then in my WHERE i added:

(PATS_WITH_PL_DIAGS.ICD10_CODE IN (SELECT ParamValues.ID.value('.','VARCHAR(MAX)') FROM @ICD_VALUE_ARRAY.nodes('id') AS ParamValues(ID))
OR PATS_WITH_PL_DIAGS.ICD9_CODE IN (SELECT ParamValues.ID.value('.','VARCHAR(MAX)') FROM @ICD_VALUE_ARRAY.nodes('id') AS ParamValues(ID))
)
