Dan,

Are you referring to an index on the source table (which is remote)? Since I'm creating the table on the destination side, there is no index. However, I am creating several indexes after the table created.

The answer is to use SQL%ROWCOUNT. I'm curious - how will an index help?

Thanks for the help.

Arup,
Any chance there will be an index on the table?

                  Subject:        Getting Number of Rows in CTAS across DBLink

List,

When I create a table as select * from another table across a dblink, how do I find out how many rows were created in the table? Is there a statistic somewhere, documented or otherwise, that tells me how many rows were fetched?

Currently I am using a rather convoluted approach - using the statistic, bytes received via SQL*Net to dblink, and dividing that by the average row size to get an approximate idea of the number of rows. However, this approximation is far from even reasonably accurate; and since the rowsize can change radically, it can be way off the mark. Any help or pointers will be highly appreciated.

Thanks.

Arup Nanda
