Description
string 
db2_stmt_error ( [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
   db2_exec().
  
   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.
