Can any body Help me to prepare statement

Question

I want to provide dynamic table name for preparestatement that i just pass table name every time and it pass me total number in that table.
I create this prepare statement
PreparedStatement prepStmt=conn_.prepareStatement("select count(*) Total from ?");
prepStmt.setString(1,"new");
but it is giving error
[JDBC SQL Server Driver] Line 1: Incorrect syntax near 'new'.
Any body can help me??
I will appreciate.

Answer 1

In PreparedStatement, the setString method adds quotes at the start and at the end of your String.
So your request :
select count(*) Total from ?
is interpreted :
select count(*) Total from 'new'
One possible solution is to pass your tablename parameter directly in the precompiled request :
String myTableName = "new";
PreparedStatement prepStmt=conn_.prepareStatement("select count(*) Total from "+myTableName);
In your database, you will store as many precompiled Statement as you will call this method with different parameters.
Hope it helps !
