( [resource stmt] )
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(), the driver returns the SQLSTATE
value associated with the last attempt to return a statement resource, for
example, from db2_prepare() or
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() to retrieve an
explicit error message and the associated SQLCODE value.
