RE: Another SQL question

John,

What do you want to happen if no row is found in the pmspag00 table?

If that "can't" happen:

Update jacfiles.agcy_ext set bus_name = 
        (select acnm_name1 
                from rugr80dat.pmspag00
                where mco = agnm_mco and agcy = agnm_agcy)

If that "can" happen, and you don't want to change those records then:

Update jacfiles.agcy_ext set bus_name = 
        coalesce(       (select acnm_name1 
                                from rugr80dat.pmspag00
                                where mco = agnm_mco and agcy =
agnm_agcy)
                        , bus_name)

The coalesce function returns the first non-null entry in the list. If
the subselect finds something it will be non-null and used. If it
doesn't find a row it will be null and the second parm to coalesce will
be used, which is the original value, effectively setting bus_name to
bus_name (ie, no change).
