System_File
Indicates if the table is a DataFlex system table.
Supported By
All Drivers
Value
- YES
- NO
Associated Attribute
DF_FILE_IS_SYSTEM_FILE (Boolean)
Remarks
System tables are treated in a special way. They should contain one record and one record only. When a system table is opened, the first (and only) row in the table will be placed in the table’s record buffer.
The DataFlex Embedded Database determines this attribute by the maximum number of records. In the other supported back ends, we cannot set a maximum number of rows. Be aware that the number of records in the table does not need to be one. This is determined by program logic, not by the driver.
