here according to their actual situation configuration. Then open PL/SQL, set the OCI Library and Oracle_home in Perference, my settings are OCI library=c:\oracleclient\oci.dll,oracle_home=c:\ OracleClient.

According to their actual situation configuration, is actually just download down the path of the package. There is one last problem, you need to set a character set, so that the query out of the data will not be garbled, write a batch processing Pldev. BAT is placed in the PL installation directory with the following contents:

Set Nls_lang=simplified Chinese_china. Zhs16gbk
PLSQLDev.exe

This character set, refers to the server side of the character set, please configure according to the actual situation.
