The SYSCOLUMN view is provided for compatibility with older versions of the software that offered a SYSCOLUMN system table. However, the previous SYSCOLUMN table has been replaced by the ISYSTABCOL system table, and its corresponding SYSTABCOL system view, which you should use instead.
The tables and columns that make up this view are provided in the SQL statement below. To learn more about a particular table or column, use the links provided beneath the view definition.
