I was wondering how many rows are in the table being updated? Do you have an index on the columns in
the where clause? Could be doing a full table scan to find all the rows. Also, if there a lot of
indexes on the table it could add a lot of time to the update.

Hmm... are there any triggers on the table that fire?

Do you have a unique index on nxx_id, npa_id, and lata_id?

Hi all,

I write a script to update 10,000 records in my database and noticed it took more than an hour to update 10,000 records. The script just includes 10,000 SQL update commands as shown below. Is the time too long to update 10,000 records? Is it a way to improve the update task to run faster. Please advise.

A portion of my update script is shown below:

update dbimpl.npa_nxx set ported_flag = 1 where nxx_id = 206 and npa_id = 201 and lata_id = 224;

update dbimpl.npa_nxx set ported_flag = 1 where nxx_id = 207 and npa_id = 201 and lata_id = 224;

Thanks,
David
