If no criteria are specified in the query form, all records that are not null are returned. This criteria statement returns all the records that match the criteria. Because the asterisk is a hard-coded criteria value (for example, Like "*"), records with null values are returned. Note that the asterisk (*) is considered a parameter because it is part of a larger Like expression. If the criteria are null, all the records are returned. This criteria statement returns both records that match the criteria and records that are null. Like Forms! FormName! ControlName& "*" Or Is Null If you omit a Start Date value on the form, however, the query returns all records, regardless of the End Date value. Records whose start and end dates fall between the values that you specify on the query form are returned. You can use this criteria statement to query a date field by using Start Date and End Date text boxes on the query form. For example, if you enter "Jo" in a field by using this criteria statement, the query returns every record in the field that begins with "Jo." This includes Johnson, Jones, Johanna, and so on.īetween Forms! FormName!StartDate And Forms! FormName!EndDate Or _ This criteria statement is the same as the QBF sample above, except that you can query by using a wildcard. Like Forms! FormName!

These criteria return all matching records. The sample QBF query in this article implements criteria in the query asįorms! FormName! ControlNameOr Forms! FormName!

A table that has fields for Name, Address, City, State, and ZIP Code can have a QBF form that has corresponding fields. The QBF form resembles a data entry form that has fields that match the fields in a table. You make entries only in the text boxes for which you want to specify search criteria. Each text box represents a field in a table that you want to query. In the QBF technique, you create a form in which you enter query criteria. This technique is called query by form (QBF).
