db2_stmt_error - Returns a string containing the SQLSTATE returned by an SQL statement

SYNOPSIS
string db2_stmt_error ([resource $stmt]) DESCRIPTION
Returns a string containing the SQLSTATE value returned by an SQL statement. If you do not pass a statement resource as an argument to db2_stmt_error(3), the driver returns the SQLSTATE value associated with the last attempt to return a statement resource, for example, from db2_prepare(3) or db2_exec(3). To learn what the SQLSTATE value means, you can issue the following command at a DB2 Command Line Processor prompt: db2 '? $sqlstate- value'. You can also call db2_stmt_errormsg(3) to retrieve an explicit error message and the associated SQLCODE value. PARAMETERS
o $stmt - A valid statement resource. RETURN VALUES
Returns a string containing an SQLSTATE value. SEE ALSO
db2_conn_error(3), db2_conn_errormsg(3), db2_stmt_errormsg(3). PHP Documentation Group DB2_STMT_ERROR(3)
