Question

I have this code :

    String check="SELECT COUNT(*) as check FROM recordstudent WHERE STUDENT_ID="+T_STUDENT_ID+" AND COURSE_ID="+T_COURSE_ID+" AND PACKAGE_ID="+T_PACKAGE_ID+" AND ACTIVITY_ID="+T_ACTIVITY_ID+" AND DATE="+T_DATE+ ";";
    rs=myStmt.executeQuery(check);
    int ch=0;

    while(rs.next()){

        ch=Integer.parseInt(rs.getString("check"));
    }

    if(ch==0)
    {

        String insertRecord="insert into recordstudent"+
                "(STUDENT_ID,COURSE_ID,PACKAGE_ID,ACTIVITY_ID,TEST_NAME,DATE,SCORE,TOTAL_MARKS,PERCENTAGE,CORRECT_ANSWER,TOTAL_QUESTIONS,STUDENT_NAME,SCORE_PER_DIVISION,ATTEMPTS)"+
                "VALUES("+
                "'"+T_STUDENT_ID+"',"+
                "'"+T_COURSE_ID+"',"+
                "'"+T_PACKAGE_ID+"',"+
                "'"+T_ACTIVITY_ID+"',"+
                "'"+T_TEST_NAME+"',"+
                "'"+T_DATE+"',"+
                "'"+T_SCORE+"',"+
                "'"+T_TOTAL_MARKS+"',"+
                "'"+T_PERCENTAGE+"',"+
                "'"+T_CORRECT_ANSWERS+"',"+
                "'"+T_TOTAL_QUESTIONS+"',"+
                "'"+T_STUDENT_NAME+"',"+
                "'"+T_SCORE_PER_DIVISION+"',"+
                "'"+t+"'"
                +");";

                myStmt.execute(insertRecord);



    }

This snippet should insert the data in database only if the ch=0 .But I am getting this error:

      com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 
          You have an error in your SQL syntax; check the manual that corresponds 
          to your MySQL server version for the right syntax to use near 
          'check FROM recordstudent WHERE STUDENT_ID=11 AND COURSE_ID=2 AND PACKAGE_ID=11 A' 
          at line 1 

Can Anyone help me and solve my problem ?

check is a reserved word. Surround it with backticks: `check`
