If I understood your question correctly you want to have a dynamic table name in a CREATE TABLE command and you're worried about SQL injections (which of course is a good thing!),

If that's the case, one possibility is that you rely on the naming restrictions. For example, you don't allow any escaped characters, semicolons, quotation marks and so on in the table name in the text box. Eliminating all the delimiter characters would help to prevent many of SQL injections.

However, if you're about to create dynamically named tables, I feel that you could solve the requirement in another way. Without knowing anything more about the actual situation I would guess that you could have a single, pre-defined table and add more columns to the table to distinguish the rows.
