Your problem is that you are 'confused'. Since this problem is not technical or related to code, I can't help you on this. And yes, regarding the code, I can suggest you to use parenthesis to enclose the operands and operators wherever you feel to make the code readable. Also remember that the OR operator takes precedence over AND

For. eg.

C#

String SqlStatment = "SELECT * FROM [View_AnIssues] where (numField=value AND YearField =Value2 )Or NeedsField=Value2;
