DataException
Exception thrown when an operation fails due to invalid data values during execution.
Unlike syntax or definition errors, this occurs when the query structure is correct, but the runtime values (often parameters) cause an error. Examples include string truncation, numeric overflow, division by zero, or invalid text representation of a data type.
Parameters
The SQL state code returned by the database.
The original error message from the database server.
Properties
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 reason for the data error.
The raw error message received from the database, if applicable.
