The following topics are covered below.
When you specify a query in the X-Query window, you must always provide server, database, collection and query expression.
To specify an X-Query
In the Server text box, specify the name of the server on which you want to execute your query.
In the Database text box, specify the name of a database of the above server in which you want to execute your query.
In the Collection text box, specify the name of a collection in the above database in which you want to execute your query.
In the query area below the above text boxes, specify the query expression using Tamino's X-Query language. See X-Query User Guide and X-Query Reference Guide in the Tamino XML Server documentation for detailed information.
The sorting sequence specified with the
instance descriptor
is not applied in the X-Query window. In the X-Query window, you can specify
your own sorting sequence in the query expression (for example, with the
sortby clause).
You can now execute the query as described below. See Executing an X-Query.
When you create a new query, any information in the query area is deleted.
Note:
The result of the previous query is not overwritten until you
execute the new query.
To create a new X-Query
From the menu, choose .
Or:
Press CTRL+N.
Or:
Choose the following toolbar button:
A dialog box appears asking whether you want to save the currently displayed query.
Choose either the or button.
When you choose the button and the current query has not yet been saved in a file, the Save As dialog box appears. See Saving an X-Query below.
The query area is now empty.
Specify a query expression and execute the query.
When you have specified a query and want to display the result, you have to execute the query.
You can search for both XML instances and non-XML instances. Two different types of query are available for these two types of instances and they are executed using different commands (see below).
Depending on the type of query different information is shown in the navigation tree:
XML Query
The ino:id is shown for fragments and non-XML instances.
For XML instances, the ino:id and/or
instance descriptor
is shown.
Non-XML Query
The ino:docname is shown for XML and non-XML instances.
When ino:docname is not available for an XML instance, the
ino:id is shown.
The result contents are shown in different ways, depending on the type of query:
| XML Query | Non-XML Query | |
|---|---|---|
| XML Instance or Fragment | The XML code with ino:id is shown
in plain view and tree view.
|
The XML code without ino:id is
shown in plain view.
|
| Non-XML Instance | The attributes ino:id and
ino:docname are shown in plain view and tree view.
|
The content of a non-XML instance is shown. |
For a list of all non-XML formats that can be displayed with the Tamino X-Plorer, see the description of the main application window's Content pane.
When you execute a query for a database which has not yet been connected, the Connect dialog box appears and you have to specify all required logon information. See Connecting to a Tamino Database.
Each new query that is executed overwrites the previous result pack. If you want to save your result pack, see Saving the Current Result Pack.
Note:
The result of a query may provide both XML and non-XML
instances.
