Question

I need to do the following :

select table1.abc from table1 where col1 = ? and col2 = ?

The problem here is i need to get data from this table for 3 sets of (col1, col2).
I don’t want to execute the same query 3 for different parameters.

Also i want to have the result set of the executed query containing 3 columns of data (1 for each set of col1,col2).

Let me know if any further details are reqd.

You can just use subselects if there’s only one result for your query:

select (select table1.abc from table1 where col1 = ? and col2 = ?),
    (select table1.abc from table1 where col1 = ? and col2 = ?),
    (select table1.abc from table1 where col1 = ? and col2 = ?)
from table1
limit 1
