Allow_Structure_Changes

Determine what type of restructure is allowed on a table.

Supported By

• DataFlex SQL Drivers (SQL Server, DB2, and ODBC)

Value

• ALL_TABLE_CHANGES_ALLOWED
• ONLY_TABLE_INT_FILE_CHANGES_ALLOWED
• NO_TABLE_CHANGES_ALLOWED

Associated Attribute

• DF_FILE_ALLOW_STRUCTURE_CHANGES (Boolean)

Remarks

Changing properties of a table may result in changes in the INT file only (client-side changes) or changes on the server (server-side changes). In some situations, it may be desirable to allow only client-side changes. In that case, this keyword can be set to ONLY_TABLE_INT_FILE_CHANGES_ALLOWED to protect against server-side changes.
