The fields in the SQLCA have the following meanings:
sqlcaid An 8-byte character field that contains the string SQLCA as an identification of the SQLCA structure. This field helps in debugging when you are looking at memory contents.
sqlcabc A long integer that contains the length of the SQLCA structure (136 bytes).
sqlcode A long integer that specifies the error code when the database detects an error on a request. Definitions for the error codes can be found in the header file sqlerr.h. The error code is 0 (zero) for a successful operation, positive for a warning, and negative for an error.
For a full listing of error codes, see Messages d'erreur.
sqlerrml The length of the information in the sqlerrmc field.
sqlerrmc Zero or more character strings to be inserted into an error message. Some error messages contain one or more placeholder strings (%1, %2, ...) that are replaced with the strings in this field.
For example, if a
Table Not Found error is generated, sqlerrmc contains the table name, which is inserted into the error message at the appropriate place.
For a full listing of error messages, see Messages d'erreur.
sqlstate The SQLSTATE status value. The ANSI SQL standard defines this type of return value from a SQL statement in addition to the SQLCODE value. The SQLSTATE value is always a five-character null-terminated string, divided into a two-character class (the first two characters) and a three-character subclass. Each character can be a digit from 0 through 9 or an uppercase alphabetic character A through Z.
Any class or subclass that begins with 0 through 4 or A through H is defined by the SQL standard; other classes and subclasses are implementation defined. The SQLSTATE value '00000' means that there has been no error or warning.
For more SQLSTATE values, see Messages d'erreur SQL Anywhere triés par code SQLSTATE.
