Paradox assigns your working directory the temporary alias WORK (even if it already has another alias name). If you create a project alias, Paradox creates a file called PDOXWORK.

You can navigate through the tables and manipulate the view of the data. use Filters to display only those records that meet certain conditions you specify or ... | 292806769-Paradox-9-Eng.pdf |
Keep the tables familiar. Its often best to create tables that correspond to the kinds of objects, like forms and files, you already use. Avoid redundancy. Beyond the common fields (primary and foreign keys)necessary for linking tables, dont duplicate information in different tables. Creating a Paradox table The fi... | 292806769-Paradox-9-Eng.pdf |
Keys Paradox uses key fields to link tables and to sort records. Keys can be either primary or composite. Primary Keys: When you designate a primary key field, it must be the first field in the table and it must be unique. This means that it mustconsist of data that could not possibly be duplicated. For example, it is... | 292806769-Paradox-9-Eng.pdf |
In addition to borrowing the structure of a table, you can also borrow its primary (key) or secondary indexes, validity check definitions, referentialintegrity, and table lookup definitions.

Picture Validity Checks A picture validity check acts as a template that formats the value you enter in a field. For example, if you specify the picture (###)###-#### (acommon template for U. S. phone numbers) and enter the value 4085551234,Paradox formats the value into (408)555-1234. You can use these charactersin a ... | 292806769-Paradox-9-Eng.pdf |
