Specifying additional criteria on query forms
To specify additional criteria:
- In a query form, select the Additional Criteria tab.
 - From the first drop-down list box, select a field on which you want to filter.
 - In the second drop-down list box, select the operator you want to
                        			 use. 
                        		  
For more information about the operators available, see Operators on Query Forms.
 - In the third field, enter a value that you want to use as the
                        			 search criteria. Remember that: 
                        		  
- You can use the wildcard character to match unspecified characters.
 - To find records containing a null value in the field, you can enter the Null keyword.
 - To use the Null keyword, the operator must be = (equals). To find records in which the field is not null, use the Null keyword with the <> (not equal) operator.
 
For more information about the Null keyword, see Using the Null Keyword.
 - To find records compared to the current date, you can use the CURDATE() keyword. See Sample Queries for more information.
 - Alphabetic input is not case-sensitive.
 - Specify whether to join the current query clause with the previous
                        			 clause by AND or OR: 
                        		  
- To use OR, select the check box labeled OR instead of AND with previous clause.
 - To use AND, clear the check box labeled OR instead of AND with previous clause.
 - If the current clause is the first clause you have defined for the query form, accept the default, which is AND.
 - If you specified any primary criteria, be sure to select AND or OR according to how you want to join the current clause with the primary criteria.
 
 - Click Add. The system adds the clause to the list.
 - Repeat steps 2-6 for each additional clause.
 - Optionally, to remove a clause from the list, select the clause and click Remove.
