Usare il Navigatore filtro

Per collegare svariate condizioni di filtro con l'operatore booleano O, fare clic sull'icona Navigatore filtro nella barra dei filtri. Si apre la finestra di dialogo Navigatore filtro.

The filter conditions that have been set appear in the Filter navigator. As soon as a filter is set, you see a blank filter entry at the bottom of the Filter navigator . You can select this entry by clicking the word "Or". Once you have selected the blank filter entry, you can enter additional filter conditions in the form. These conditions are linked by Boolean OR to the previously defined conditions.

The context menu can be called for each entry in the Filter navigator. You can edit the filter conditions in this area directly as text. If you wish to check if a field has content or no content, you can select the filter conditions "empty" (SQL:"Is Null") or "not empty" (SQL: "Is not Null"). It is also possible to delete the entry by using the context menu.

Potete spostare le condizioni dei filtri nel Navigatore di filtri tramite drag&drop, o utilizzando i tasti +Alt+Freccia su o +Alt+Freccia giù. Per copiare le condizioni dei filtri, trascinatele tenendo premuto il tasto .

While designing your form, you can set the "Filter proposal" property for each text box in the Data tab of the corresponding Properties dialog. In subsequent searches in the filter mode, you can select from all information contained in these fields. The field content can then be selected using the AutoComplete function. Note, however, that this function requires a greater amount of memory space and time, especially when used in large databases and should therefore be used sparingly.
