DB2 SELECT EXCEPT with WHERE clause

阅读更多关于 DB2 SELECT EXCEPT with WHERE clause

问题 I'm trying to compare two tables in a DB2 database in z/OS using SPUFI to submit SQL queries. I'm doing this by using EXCEPT to see the difference between two SELECT queries. I need to filter the SELECT statement from the first query with a WHERE clause.
