SQLSTATE indicates whether the most recently executed SQL statement resulted in a success, error, or warning condition.
The database server sets a SQLSTATE and SQLCODE for each SQL statement it executes. A SQLSTATE is a string that indicates the whether the most recently executed SQL statement resulted in a success, warning, or error condition.
Each SQLSTATE represents errors that are common to all platforms, and usually contain non-product-specific wording. The format of a SQLSTATE value is a two-character class value, followed by a three-character subclass value. Guidelines for SQLSTATE conformance with regard to class and subclass values are outlined in the ISO/ANSI SQL standard.
SQL Anywhere conforms to the ISO/ANSI SQLSTATE conventions with the following additions and exceptions:
|Class and subclass||Condition|
|01WCx||Warnings related to character set conversion|
|38xxx||External function exception|
|42Xxx||Syntax error: expressions|
|42Rxx||Syntax error: referential integrity (for example, attempt to create second primary key)|
|42Wxx||Syntax error: generic|
|42Uxx||Syntax error: duplicate, undefined, or ambiguous object reference|
|54Wxx||Product limit exceeded|
|55Wxx||Object not in required state for operation to succeed|
|57xxx||Resource not available or operator intervention|
|5Rxxx||SQL Remote errors|
|WBxxx||Online backup errors|
|WIxxx||Internal database errors|
|WPxxx||Errors in procedures, variables, and so on|
|WLxxx||Errors loading and/or unloading|
|WWxxx||Miscellaneous SQL Anywhere-specific errors/warnings (including system failures)|
|WOxxx||Remote data access feature-related errors|
|WJxxx||JCS and JDBC related errors|
|WCxxx||Character translation errors|
The successful completion class is '00xxx' (for example, '00000').
SQLSTATE and SQLCODE are related in that each SQLCODE corresponds to a SQLSTATE, and each SQLSTATE can correspond to one or more SQLCODEs.
To return the error condition associated with a SQLSTATE, you can use the ERRORMSG function.
SQL/2008 SQLSTATE classes (the first two characters) beginning with the values '0'-'4', and 'A'-'H' are defined by the ANSI standard. Other classes are implementation-defined. Similarly, subclass values that begin with values '0'-'4', and 'A'-'H' are defined by the ANSI standard. Subclass values outside these ranges are implementation-defined.
