Completion Insight Affects Performance When Executing Query
Last updated on OCTOBER 27, 2016
Applies to:Oracle SQL Developer - Version 4.0 and later
Information in this document applies to any platform.
A query: select * from table where col1 = 372223, with a non-unique index on col1, runs slow in sql developer.
The execution time is appr. 20 ms in sqlplus (or toad) and appr. 30 sec in sql developer.
On repeating the query in sql developer it also becomes fast, until the query is changed (and has to be reparsed).
