Below code works to combine Like and IN. But I need a column in the output with the values that I used for the Like:
SELECT file_id FROM table1 as t WHERE archival_date = '20180108' WHERE EXISTS(SELECT * FROM (VALUES ('%portfolo1filename%'), ('%portfolo2filename%'), ('%portfolo3filename%')) Vals(val) WHERE filename LIKE '%' + val + '%')
What I need as Output:
____________________________ val file_ID ____________________________ portfolo1filename 2230 portfolo2filename 2240 portfolo3filename 3345
Current code’s Output:
______________ file_ID ______________ 2230 2240 3345
Note: val here contains the list of values (i.e filenames) that I need to search as like
table1 has following entries:
filename file_ID archival_date __________________________________________________________________ Broker1_portfolo1filename 2230 20180108 Broker1_portfolo2filename 2240 20180108 Broker2_portfolo3filename 3345 20180908 Broker2_portfolo2filename 1345 20180904 Broker3_portfolo1filename 3045 20180906 Broker2_portfolo2filename 3355 20180907 Broker2_portfolo3filename 7340 20180901

One solution would be to convert your WHERE EXISTS
clause to an INNER JOIN
, like :
SELECT t1.file_id, vals.val FROM table1 t1 INNER JOIN (VALUES ('value1'), ('value2'), ('value3')) Vals(val) ON t1.column1 LIKE '%' + vals.val + '%'
The downside of this approach is that if multiple expression match the value of column1
in a given record, you will find two rows in the output. To avoid that, you could for example concatenate all succesfully matched expressions in a single field.
If you are using SQL Server 2017 (your query runs fine on this RDBMS), you can use STRING_AGG
:
SELECT t1.file_id, STRING_AGG(vals.val, ',') FROM table1 t1 INNER JOIN (VALUES ('value1'), ('value2'), ('value3')) Vals(val) ON t1.column1 LIKE '%' + vals.val + '%' GROUP BY t1.file_id
