Filtering data rows
Databases typically contain vast amounts of data. Reports, however, typically use a small subset of the data, so SQL queries often contain filter conditions to limit the rows returned.
How to filter data rows
1 Choose Conditions.
2 Create a filter condition.
1 In Column, select a column or Build Expression to create an expression.
2 In Operator, select an operator.
3 In Value, select a column or type a value.
4 In AND/OR, optionally select AND or OR to specify another filter condition.
