Dear Friends,

Postgres 7.3.2 on Linux 7.

I want to compare to columns and get the logical result as follows.

C1 is 'YNYNY' . C2 is 'NNYYY'.

I want to compare like AND and OR operators.

C1 AND C2 should give result like NNYNY.

C1 OR C2 should give result like YNYYY.

Please shed some light.

Thanks

Kumar
