Write Table operation causes a unique constraint violation

Question

Write Table operation causes a unique constraint violation. How can I deal with it?

Answer

Generally, a unique constraint violation occurs when duplicate data is written to a column for which a unique constraint is set.

Therefore, it depends on the records that exist in the table and the records to be written.

As described above, please consider changing the settings on the DB side or writing data that does not fall under the unique constraint as a countermeasure.
