Chapter 7: Databases and Data Sources
There are various search options, including searching in one field rather than all fields,
position of the value with in the field, which direction to search in the database, etc.
The ? and * wildcards can also be used, as in the Find and Replace dialog. Additional
information about the database search function can be found in Help.
Searching With a Form Filter
To search with a form filter:
1. Open a form.
2. Click the Form-Based Filters button, on the Form Navigation toolbar.
3. The Form Filter toolbar opens. Enter a value in the appropriate field.
4. Click the Apply Form-Based Filter button.
5. The form is now filtered based on the data entered.
A filter can be removed by clicking the Remove Filter/Sort button.
When formulating filter conditions, various operators and commands are available. Apart
from the relational operators there are SQL-specific commands that query the content of
database fields. If these commands are used, in the OpenOffice.org syntax, OpenOffice.org
automatically converts these into the corresponding SQL syntax. SQL commands can also be
entered directly. The following tables give an overview of the operators and commands:
Operators
Operator Meaning Condition is satisfied if...
= equal to ... the content of the field is identical to the indicated
expression. The operator = will not be displayed in the
query fields. If a value without any operator is entered,
the operator = will be automatically adopted.
<> not equal to ... the content of the field does not correspond to the
specified expression.
> greater than ... the content of the field is greater than the specified
expression.
< less than ... the content of the field is less than the specified
expression.
>= greater than or
equal to
... the content of the field is greater than or equal to the
specified expression.
<= less than or
equal to
... the content of the field is less than or equal to the
specified expression.
