Question

I am trying to update a value if record exists else insert the values to database. However, that is not working. I have written the below code.

 String sqlCheck = "Select * from [UAP].[dbo].[UAP_EMPLOYEE] where EMP_EMPLOYEE_ID = '"+empId+"' ";
    PreparedStatement prpStatementCheck = conn.prepareStatement(sqlCheck);
    prpStatementCheck.setString(1, EMP_EMPLOYEE_ID);
    ResultSet rsCheck=prpStatementCheck.executeQuery();
    String check=null;

     while((rsCheck.next())
    {
         if(rsCheck.next()>0)
          update statement; 
         else
             Insert Statement; 
    }

As EMP_EMPLOYEE_ID field is an INTEGER type, use setInt rather than setString:

String sqlCheck = "Select * from [UAP].[dbo].[UAP_EMPLOYEE] where EMP_EMPLOYEE_ID = ?";
PreparedStatement prpStatementCheck = conn.prepareStatement(sqlCheck);
prpStatementCheck.setInt(1, EMP_EMPLOYEE_ID);
