Hi ,

I found that your given query contains syntax error..

SQL

update tbl_fs_mst set d_date_from=isnull(SELECT MAX(D_DATE_REPORT) FROM TBL_DWR WHERE C_FS_Code=@oldfscode),'2015/02/01')

you missed parenthesis in your query , so the corrected query is..

SQL

update tbl_fs_mst set d_date_from=isnull((SELECT MAX(D_DATE_REPORT) FROM TBL_DWR WHERE C_FS_Code=@oldfscode),'2015/02/01')

just try this...

Thanks

Not sure if you're trying to update rows having NULL values but perhaps something like:

SQL

update tbl_fs_mst 
set d_date_from=(SELECT ISNULL(MAX(D_DATE_REPORT),'2015/02/01') 
                 FROM TBL_DWR 
                 WHERE C_FS_Code=@oldfscode)
WHERE date_from IS NULL
