Using content assist (Mapping syntax)
Use content assist to find the variable names for input and output objects, database elements, and paths.
Press Ctrl+Spacebar to display content assist, and use it to help you build your XPath statements and mapping expressions. Content assist provides the variable names that you need to use to reference elements in your XPath statements and expressions. The variable name assigned for the same element can vary between uses in different transforms, so always use content assist to obtain the correct variable name. Avoid copying and pasting expressions that include variable names.

- Data from database tables
Database objects with names that do not conform to the XML NCName format
Some database objects
have names that do not conform to the XML NCName format (for example,
the name contains characters like #, or $). If the database object
name is used in SQL (for example, in the
of the Select transform), no action is required.
If the database object is used in XPath (for example, in a Custom
transform or a condition), use content assist, which adds the appropriate
