Question

I need help on T-SQL. I have a stored procedure in my SQL Server with query (sample) as below:

Select empid, empname, sal from emp
  where empname like '%jo%'
  and   empname like '%el%'

Let’s say, the above query returns records as shown below:

empid empname sal   
17    john    $1000
45    elena   $2000

I need to have another column to the above select statement which should say 'jo' for %jo% record and 'el' for %el% record. For example:

empid empname sal     SearchString
17    john    $1000   jo
45    elena   $2000   el

Is this possible?

Thank you

To cater for multiple conditions you can make use of a CTE

• to create an in-memory table
• join the actual table to this in-memory table
• retrieve the condition in the select clause

SQL Statement

;WITH Conditions (SearchString) AS (
  SELECT 'jo' UNION ALL
  SELECT 'el'
)
SELECT  empid
        , empname
        , sal
        , Searchstring
FROM    emp e
        INNER JOIN Conditions c ON e.empname LIKE '%' + c.SearchString + '%'

Test script

;WITH Conditions (SearchString) AS (
  SELECT 'jo' UNION ALL
  SELECT 'el'
)
, emp (empid, empname, sal) AS (
    SELECT 17, 'john', 1000 UNION ALL
    SELECT 45, 'elena', 2000
)
SELECT  empid
        , empname
        , sal
        , Searchstring
FROM    emp e
        INNER JOIN Conditions c ON e.empname LIKE '%' + c.SearchString + '%'
