Why is OracleDataAdapter.Fill() Very Slow?

问题 I am using a pretty complex query to retrieve some data out of one of our billing databases.

I'm only trying to read about 1000 rows, and the query completes in SQL Developer in about 20 seconds. What could be causing such drastic differences in performance? I have tons of other queries that run quickly

When I asked him to install these new ODAC version using XCOPY in a different folder and then include my application in the test server, he answered me that I should use ODAC 11.106.21 because he could have troubles with his
