Advanced parametrization in JDBC PreparedStatements [duplicate]

Answer 1

Use placeholder in place of table name and then replacing that with your tablename.

String strQuery = "INSERT INTO $tableName (col1, col2)
                   VALUES (?,?);";

and replace when you come to know the tablename as below:

String query =strQuery.replace("$tableName",tableName);
stmt =connection.prepareStatement(query);
