Internal CA Dataquery Table

An internal table is used to keep track of the following:

• Columns and SET statements in an INSERT query.
• Columns and keys referenced in a query.
• Titles.
• Alternate headings (whether from DD or specified in the query).
• All the simple columns that make up a key.
• All column entries. Only columns with class S (simple), C (compound), or F (filler) can be accessed in DQL Mode.
• Repeating field subscripts. (A maximum of two levels is allowed.)
• Totals and column functions.
• Restricted conditions.
• Edit patterns (whether from DD or specified in the query).

An excess of one or more of these items can make this internal table overflow.
