Dear List,

I'm trying to copy an unknown amount of data  from a file to a table unsing a copy command.

This is working without any problems.

Now I want to get the number of copied rows.

In psql this is retuned as a text 'COPY XXX'

How can I get this in ECPG?

Using a prepared DELETE- or  INSERT- statement I can simply execute the statement INTO a var.

EXEC SQL BEGIN DECLARE SECTION;const char        *stmt_1 = "DELETE FROM my_table;";int        myVar;
EXEC SQL END DECLARE SECTION;

EXEC SQL PREPARE stmt_1 FROM :stmt_1;
EXECUTE stmt_1 INTO :myVar;

Var now contains the number of deleted rows.

But...

EXEC SQL BEGIN DECLARE SECTION;const char        *stmt_1 = "COPY my_table FROM '/tmp/file.data';";int        myVar;
EXEC SQL END DECLARE SECTION;

EXEC SQL PREPARE stmt_1 FROM :stmt_1;
EXECUTE stmt_1 INTO :myVar;

mvVar is always 0.

Any suggestions how to get the numer?
