If this is the first message written to the error file, a message is written to stderr (and
to stdout if it is different from stderr) to indicate that errors are occurring. If the -Q
argument was specified, the write to stderr is skipped, and if stdout is the same as
stderr, the message is not written.
This procedure does not increment the error count.
The syntax for this procedure follows:
DTLWRITETOERRCOB
This procedure writes the message to the process error file (the file specified by -E or
stderr if -E was not specified).
If this is the first message written to the error file, a message is written to stderr (and
to stdout if it is different from stderr) to announce that errors are occurring. If the -
Q argument is specified, the write to stderr is skipped, and if stdout is the same as
stderr, the message is not written.
This procedure does not increment the error count.
The syntax is:
DTLWRITETOUSERCOB
This procedure writes the message to stderr and to stdout (unless stdout is the
same as stderr). If the -Q parameter is specified, the write to stderr is skipped, and

procedures check SQLSTATE to determine whether the operation was successful and,
if so, how many rows were affected. This information is used to:
