Sql huge insert script

Question

I took a backup of a table in the form of insert script using toad for oracle. I could not use that script in toad to perform inserts because of the huge size. Is there a way that i can run the huge script using toad?

Answer 1

1. Reduce network time by running the script on the server. Chances are the vast majority of the time is spent waiting for the network. Normally each INSERT statement is a separate round-trip.

2. Reduce network time by batching the inserts. Wrap a begin and end; around a large number of inserts. A PL/SQL block only requires one round-trip. Note that you probably cannot put the entire script in a single anonymous block as there are parsing limits. You will get DIANA errors with anonymous blocks larger than roughly a few megabytes in size.

3. Run the code indirectly. Maybe just loading the file in Toad is the problem? Run a script that simply calls that script, perhaps something like @my_script.sql?

Without knowing more about Toad or what the script looks like I cannot say for sure if these will work. But I've used these approaches with similar issues, there is usually a way to make simplistic install scripts run more than 10 times faster.

Answer 2

Try running the script in SQLPLUS using '@'
