Constructing dynamic columns from parameters in Sybase
- by Chapax
Hi,
I'm trying to write a stored proc (SP) in Sybase.
The SP takes 5 varchar parameters.
Based on the parameters passed, I want to construct the column names to be selected from a particular table.
The below works:
DECLARE @TEST VARCHAR(50)
SELECT @TEST = "country"
--print @TEST
execute("SELECT DISTINCT id_country AS id_level, Country AS nm_level
FROM tempdb..tbl_books INNER JOIN
(tbl_ch2_bespoke_report INNER JOIN tbl_ch2_bespoke_rpt_mapping
ON tbl_ch2_bespoke_report.id_report = tbl_ch2_bespoke_rpt_mapping.id_report)
ON id_" + @TEST + "= tbl_ch2_bespoke_rpt_mapping.id_pnl_level
WHERE tbl_ch2_bespoke_report.id_report = 14")
but gives me multiple results:
1 1 row(s) affected.
id_level nm_level
1 4376 XYZ
2 4340 ABC
I would like to however only obtain the 2nd result.
Do I need to necessarily use dynamic SQL to achieve this?
Many thanks for your help.
