Oracle JDBC Thin Driver Generates Different Execution Plan
(Doc ID 273635.1)
Last updated on MARCH 26, 2019
JDBC - Version 220.127.116.11 to 18.104.22.168 [Release 8.1.7 to 9.2] Information in this document applies to any platform.
Different Execution Plans are getting generated with SQL*Plus versus JDBC Thin9i for a given set of Bind Variables. JDBC-OCI Driver works just fine - Plans generated are similar to SQL*Plus. JDBC Drivers 10g or above work do not show this behavior.
The version of the Oracle RDBMS does not seem to matter - Only the JDBC Client Version, Client Type(Thin/Thick) makes a difference.
