nValue

Specifies a number that determines how to handle conflict checking. The following table lists the values for nValue.

nValue	Description
0	Do not perform checks. (Default)
1	In single row update mode, check for update conflicts during a SQL UPDATE or DELETE operation. If conflict occurs, specifically, no record is affected by any command specified by the UpdateCmd or DeleteCmd property, return message "Update conflict (Error 1585)".
2	In single row update mode, check for key uniqueness during a SQL UPDATE or DELETE operation. If more than one record is affected by any command specified by the UpdateCmd or DeleteCmd property, return message "Warning: The key defined by the KeyField property for table "alias" is not unique. (Error 1495)"
3	Perform checks as specified by settings 1 and 2.
4	Append custom command specified in ConflictCheckCmd property to the end of the command in the UpdateCmd and DeleteCmd properties.

Note:

Due to ODBC and ADO limitations, settings 1, 2, and 3 might not work correctly if the UpdateCmd and DeleteCmd properties contain more than one command. It is possible that the number of affected rows is not returned for every command in a batch. Therefore, it is recommended that you set ConflictCheckType to 4 and specify a custom command in the ConflictCheckCmd property or make sure that only one SQL UPDATE or DELETE command will be executed. Also, Visual FoxPro disregards settings 1, 2, and 3 when performing a batched TABLEUPDATE(В ) operation.
