10 - dBASEIV Query Interface




? The dBASEIV script provides query access to VMS-baseddBASEIV databases.

H The user can, by radio button, select to generate a report in a Jfixed-font format (the default), or using native HTML tables (supported byBNetscape v1.n, but not supported by Mosaic v2.4, thecurrent VMS browser). 

B Another set of radio buttons allow selection of the reportJlayout as a table (the default), where fields are columnated, or as;a listing, where fields are presented sequentially. 

> Parameters for the query are presented using a combination ofCcheckboxes and/or text entry boxes against one, more,Dor all of the fields in a database. The checkboxes allow theGinclusion of that field in a report. The text entry boxes allowEthe specification of query strings, and provide the ability toLselectively report on records of a database depending on the contents of thefields. 

C A Submit Query button allows the completed query form to beFsent to the server, and the report generated and returned to the user. 

Query Strings



I A query string allows a field to be selected based on a wildcard match. CWildcards supported are the ``*'' and ``%''. For fields containingAnumeric values selection can be based on arithmetic comparisions. 

Query Form Builder



B To assist in building query interfaces for specific databases the8dBASEIV script will provide a form allowing theNspecification of the fields to be queried and/or displayed, and then build andLreturn a custom hypertext form to do just that. This form can then be saved0for use from, or inclusion in, another document.
