ConstraintViolationException
Exception thrown when a database operation violates a defined constraint (e.g., unique index, foreign key, check constraint).
This exception encapsulates details about the constraint violation, including the specific type of violation (reason), and optional metadata such as the schema, table, column, and constraint name involved in the error.
Parameters
The SQL state code returned by the database.
The original error message from the database server.
Constructors
Properties
The specific name of the constraint that was violated, if available.
Where this happened, innermost first, appended to by each layer as the exception unwinds. It is on the base class for the same reason queryContext is: adding to it is the only thing a frame can do to an exception without replacing it, and replacing one costs the type the caller catches on - a ConstraintViolationException restated as something else stops being the failure a retry looks for. A mapper walking a nested composite appends the attribute it was on, a transaction plan the step and parameter it was resolving. Rendered reversed, outermost first, so PATH: step 1 -> parameter 'name' -> map #1 reads from the plan down to the lambda.
The context of the query that resulted in this exception, if applicable.
The specific type of constraint violation mapped from the database error.
The raw error message received from the database, if applicable.
