A value to specify the Oracle client software version. The driver assumes that it is using the version of Oracle client software specified by this option to connect to an Oracle server.
Valid Values
8i | 9iR1 | 9iR2 | 10gR1
Behavior
When set to 10gR1 and later, the driver binds all non-integer numerics as BINARY FLOAT and BINARY DOUBLE. When set to any Oracle version previous to Oracle10g R1, the driver binds non-integer numerics as if connected to an Oracle 9i R2 or earlier version of the server (regardless of the actual version of the server to which it is connected). When connecting to an Oracle 10g server with a pre-10g client, this attribute must be set to the same version as the actual Oracle client software in use; otherwise, numeric parameter bindings may fail. Versions of the Oracle client software prior to 10g R1 do not fully support the new features of the Oracle 10g database server.
