Checking Whether Existing Data Meets the Constraints

Whether existing data meets the constraints

The constraint type of the source database table does not check whether existing data meets constraints. Some data in the source table may not meet the constraints, and the destination database may not support the constraint types. As a result, data transmission fails or data is lost because the data written to the destination database fails the constraint check.

Item to be confirmed: Some check item constraints are not met.

Handling suggestion: Ensure that all data in the corresponding table meets the current constraints. If any data does not meet the constraints, consider not configuring constraints in the destination (contact DRS online support to skip the table structure consistency check), or process the source data to ensure that the data meets the constraints.
