# Error message differences

The Network Server reports only the first error or warning message if multiple errors or warnings occur for a given statement. For example:

    ij> create table ai (x int, y int generated always as identity
    	(increment by 200000000));
    ij> insert into ai (x) values (1),(2),(3),(4),(5),(6),(7),
    (8),(9),(10),(11),(12),(13),(14),(15),(16),(17),(18),(19);

The Network Server generates the following error message and appends the exception message to the error:

    ERROR 42Z24: Overflow occurred in identity for column 'Y' in table 'AI':
    SQLSTATE: 22003: The resulting value is outside the range
    for the data type INTEGER.

The Derby embedded driver, however, would generate two SQL exceptions:

    ERROR 42Z24: Overflow occurred in identity for column 'Y' in table 'AI'.

    ERROR 22003: The resulting value is outside the range for the data type INTEGER.

This is because the network client driver reports only one SQLException or one SQLWarning per statement.
