FAQPage Schema
How do I construct a PostgreSQL UPDATE statement using the Army Criteria API?▼

To construct a PostgreSQL UPDATE statement, use the Postgres.singleUpdate() method chain in the Army Criteria API, flowing through stages like SET, FROM, JOIN, WHERE, and RETURNING to finalize with asUpdate() or asReturningUpdate().

What is the method chain flow for Postgres.singleUpdate() in Army Criteria?▼

The Postgres.singleUpdate() method chain flows from the initial update call through optional WITH, SET, FROM, JOIN, and WHERE clauses, culminating in asUpdate() or asReturningUpdate() to build the final PostgreSQL UPDATE statement.

Can I use JOIN and FROM clauses in a Postgres UPDATE statement with Army Criteria API?▼

Yes, the Army Criteria API supports adding JOIN and FROM clauses to your PostgreSQL UPDATE statement construction, allowing complex table references within the Postgres.singleUpdate() method chain before finalizing the query.

How does the Army Criteria API handle the RETURNING clause in PostgreSQL UPDATE statements?▼

The Army Criteria API handles the RETURNING clause by terminating the Postgres.singleUpdate() method chain with asReturningUpdate(), which appends the RETURNING statement to retrieve updated rows directly from the PostgreSQL query.

What source files document the Postgres.singleUpdate() UPDATE statement construction?▼

The UPDATE statement construction is documented across Postgres.java, PostgreUpdate.java, PostgreUpdates.java, and UpdateUnitTests.java, detailing method signatures and implementations for the Army Criteria API.
