Subj:   Most efficient way to make Date field into char(4) YYMM
 
From:   Anomy Anom

We have a table that has this as a lookup, so if I use that, I have code like:

     sel tbl1.col1, tbl1.col2
     from tbl1 inner join dateLkup
     on dateLkup.date_YYMM = tbl1.date_YYMM
     and dateLkup.real_date = current_date

I wondered if it might not be simpler (or more efficient) to do something like

     sel tbl1.col1, tbl1.col2
     from tbl1
     where tbl1.date_YYMM = cast(current_date as char(4)) (format'YYMM')

I'm having trouble finding the exact syntax for something like option 2 also.


Thanks in advance!
