which is better?

Loading a cobol table using a CUSOR in DB2 embedded COBOL programe?

OR

Loading a cobol table by reading a file.

This is a generic question.. So any generic views can be told..

the table has a maximum of 1K - 5K elements. - 1 dimensional with elementary items, not group..

If the data required resides in DB2 table, then reading DB2 table is better. If the data required resides in file, then reading file is better.. icon_neutral.gif

Hello,

First - the duplicate topic has been removed.

When loading a table, it is far more efficient to actually LOAD the table. Reading individual bits of data (wherever they are) and then INSERTing into new rows is most expensive.
