Hi,

Is there any way to load multiple CSV files at once using single COPY command?

I have scenario where I have to load multiple files,

COPY prdxgdat FROM 'Z:/data-2016-04-01.csv' WITH DELIMITER ',' CSV HEADER Y

COPY prdxgdat FROM 'Z:/data-2016-04-02.csv' WITH DELIMITER ',' CSV HEADER Y

COPY prdxgdat FROM 'Z:/data-2016-04-03.csv' WITH DELIMITER ',' CSV HEADER Y

COPY prdxgdat FROM 'Z:/data-2016-04-04.csv' WITH DELIMITER ',' CSV HEADER Y

COPY prdxgdat FROM 'Z:/data-2016-04-05.csv' WITH DELIMITER ',' CSV HEADER Y

COPY prdxgdat FROM 'Z:/data-2016-04-06.csv' WITH DELIMITER ',' CSV HEADER Y

..

..

COPY prdxgdat FROM 'Z:/data-2016-04-50.csv' WITH DELIMITER ',' CSV HEADER Y

50 files -> 50 COPY command, In my use case I think this is not a good way to load data, Can you suggest any better way to do this?

I can always write external script (eg: shell script) but is there any other way to do this using single COPY command?

Perhaps something like "COPY FROM PROGRAM 'cat /path/*.csv'" would work for you?
