Subj:		Re: Multiload SQL and Case statement

From:		Pinti, Michele A

The first thing I would recommend that you do is compare apples with apples. Besides, what day of the month is '1_' and how can you keep that one?

We want to keep the record but set this field to a null if it is invalid.

Regardless, you are comparing a two-byte char field out of SUBSTR with a number and making MLoad do a conversion. If you are comparing wouldn't a better comparison be BETWEEN '01' and '31' for day and '01' and '12' for month?

I tried this case statement but records with invalid values are still being dropped.

     , Case when :USAGE_YEAR_BEG_VAL_DY between '00' and '31'
            then :USAGE_YEAR_BEG_VAL_DY
            else null
            End

     , case when :USAGE_YEAR_BEG_VAL_MO between '00' and '12'
            then :USAGE_YEAR_BEG_VAL_MO
            else null
            End

Thanks,

Michele
