Subj:   Re: Numeric overflow while doing UNION
From:   Myrna, James


I have seen in the past, that when you do a UNION of 2 SQL statements, the data type for the resulting column is based on the columns in the first SELECT statement. So if your first SQL is selecting a SMALLINT and your second query is selecting a BIGINT, the result column may be a SMALLINT and the value from the BIGINT won't fit into it. Try switching the order of the two queries or CAST the numeric columns to larger values.
