Let’s discuss about the bulk upsert in Postgres. At Bobcares, with our PostgreSQL Support, we can handle your issues.

Bulk Upsert in Postgres

We can use the INSERT INTO… ON CONFLICT… DO UPDATE statement in PostgreSQL to do a UPSERT action. It is an insert or update if the entry already exists. We can effectively resolve disputes and update current records using this method. Here’s a detailed how-to:

1. We must define a unique constraint on the column(s) that determine uniqueness before we can run a UPSERT transaction. The ALTER TABLE statement can be used to add one if we don’t already have one.

2. We can use the INSERT INTO… ON CONFLICT… DO UPDATE statement to carry out the UPSERT operation after the special constraint is in place. The DO UPDATE clause outlines the update behavior, while the ON CONFLICT clause outlines the conflict resolution plan.

3. We can include more columns in the SET clause of the DO UPDATE section if we need to update more than one in the event of a conflict.

In PostgreSQL, we can securely and effectively execute UPSERT operations by using the INSERT INTO… ON CONFLICT… DO UPDATE statement. It lets us update current data when conflicts occur and guarantees that specific constraints are honored. The INSERT INTO… ON CONFLICT… DO UPDATE is limited to PostgreSQL 9.5 and higher versions.

There are various ways to accomplish a UPSERT operation for PostgreSQL 9.4 and previous versions. Using the INSERT INTO … SELECT … WHERE NOT EXISTS … query is a popular strategy.

Conclusion

Depending on the version of PostgreSQL we’re using, there may be differences in the specific method for UPSERTing records. Our Tech team can offer a more precise solution with your version of PostgreSQL.
