Like Command returning wrong result set - Mailing list pgsql-sql

Hello group,

I’m writing a script and a bit confused on the results with the like command.

gm.title like 'CP_%'

The above command gives me records with titles like CP_40, CP_2, CP_23, etc.

gm.title like '%_CT'

The above command give me records with tiles like Quiz: RadiInterpretation w/ CBCT.

I was expecting it to return titles that contained *_CT, i.e. FX_CT or DR_CT.  It’s as if it’s ignoring the underscore the way it would do if you were using ‘%CT’.  Does it ignore the underscore when it’s right after the ‘%’?

Thanks,
