To import the content of a database table, select → → Next, in the "Select database table" choose the connection you want to use.
![[Note]](img/note.gif) | Note |
|---|---|
Only connections configured on relational data sources can be used to import to XML or to generate schemas. |
You can edit, delete or add a new data source and connection: click on the "Configure Database Sources" button and the "Preferences" dialog will open at Data Sources section. Click Connect.
From the catalogs list click on a schema and choose the required table. Click Ok.
The "Import criteria" Dialog will open next, showing a default Query string like "select * from table" in SQL Query. You can click the "SQL Preview" button to see the input data displayed in a tabular form and the XML Import Preview containing an example of what the generated XML will look like. The SQL Query message is editable. You can specify which fields should be taken into consideration.
If you edit the query string so that the query does a join of two or more tables and selects columns with the same name from different tables you should use an alias for the columns like in the following example. That will avoid a confusion of two columns mapped to the same name in the result document of the importing operation.
select s.subcat_id,
s.nr as s_nr,
s.name,
q.q_id,
q.nr as q_nr,
q.q_text
from faq.subcategory s,
faq.question q
where ...- SQL Preview
Displays the labels that will be used in the XML document and its preview. Import setting: If the "SQL Preview" button is pressed, it shows the labels that will be used in the XML document and the first 5 lines from the database. All data items in the input will be converted by default to element content, but this can be over-ridden by clicking on the individual column headers. Clicking once on a column header (ex Heading0) will cause the data from this column to be used as attribute values on the row elements. Clicking a second time - the column's data will be ignored when generating the XML file. You can cycle through these three options by continuing to click on the column header. If the data column will be converted to element content, the header will contain the "<>" symbol. If the data column will be converted to attribute content, the header will contain the "=" symbol, and if it will be skipped, the header will contain "x".
- Change labels
This button opens a new dialog, allowing you to edit the names of the root and row elements, change the XML name and the conversion criterion.
The XML names can be edited by double-clicking on the desired item and entering the required label. The conversion criterion can also be modified by selecting from the drop-down list ELEMENT, ATTRIBUTE or SKIPPED.
- Open in editor
If checked, the new XML document created from the imported text file will be opened in the editor.
- Save in file
If checked, the new XML document will be saved at the specified path.
Note If only Open in editor is checked, the newly created document will be opened in the editor, but as an unsaved file.
- Generate XML Schema
Allows you to specify the path of the generated XML Schema file.
