Hasura.Backends.Postgres.SQL.Error

Description

Postgres SQL Error

Functions and datatypes for interpreting Postgres errors.

Synopsis

Documentation

data PGErrorType Source #

The top-level error code type. Errors in Postgres are divided into different classes, which are further subdivided into individual error codes. Even if a particular status code is not known to the application, it’s possible to determine its class and handle it appropriately.

Constructors

PGDataException (Maybe (PGErrorCode PGDataException)) 
PGIntegrityConstraintViolation (Maybe (PGErrorCode PGIntegrityConstraintViolation)) 
PGSyntaxErrorOrAccessRuleViolation (Maybe (PGErrorCode PGSyntaxErrorOrAccessRuleViolation)) 
PGTransactionRollback (Maybe (PGErrorCode PGTransactionRollback))
