Installation Multiple Osclass into 1 SQL File / How To Manage

Installation Multiple Osclass into 1 SQL File / How To Manage It?
I trying to install multiple osclass sites /EN/ /DE/ /TR/ /RU/ etc. into one SQL file.

But it gives error each time ; The database structure could not be created. Error number: 1064

I add of course Table prefix for each language folder ; like tr_oc_ de_oc_ ru_oc_ etc.

Why it is not installing new site into already installed SQL file?

What is wrong I am doeing?
