## Class SQLStateSQLExceptionTranslator

- java.lang.Object
- - org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator
  - - org.springframework.jdbc.support.SQLStateSQLExceptionTranslator

- All Implemented Interfaces:
    SQLExceptionTranslator

      public class SQLStateSQLExceptionTranslator
      extends AbstractFallbackSQLExceptionTranslator

  `SQLExceptionTranslator` implementation that analyzes the SQL state in the `SQLException` based on the first two digits (the SQL state "class"). Detects standard SQL state values and well-known vendor-specific SQL states.

  Not able to diagnose all problems, but is portable between databases and does not require special initialization (no database vendor detection, etc.). For more precise translation, consider `SQLErrorCodeSQLExceptionTranslator`.

      Description copied from class: `AbstractFallbackSQLExceptionTranslator`
      Template method for actually translating the given exception.

      The passed-in arguments will have been pre-checked. Furthermore, this method is allowed to return `null` to indicate that no exception match has been found and that fallback translation should kick in.

      Parameters:
        `task` - readable text describing the task being attempted
        `sql` - SQL query or update that caused the problem (may be `null`)
        `ex` - the offending `SQLException`

        the DataAccessException, wrapping the `SQLException`; or `null` if no exception match found
