skip
Use this operator to list matching results from a child
node, even if its parent node does not meet the specified
criteria. See the following example for more information.
Example: skip Criteria Operator
Say you are looking at the following structure and want to determine all of the ports that
belong to a YY type module:
• Network Element 1
• Module 1, Type XX
• Module 1.1, Type YY
• Port 1
• Port 2
• Module 2, Type YY
• Port 1
• Port 2
If you specify
Module.Type=’YY’
in your query criteria, the ports associated with
module 1.1 will not be returned since its parent module is type XX. Instead, enter
Module.Type=’YY’ or skip Module!=’YY’
. This tells XSQL to disregard any parent module
data that does not meet the type YY criteria and collect results for any matching child
modules. In this example, you are instructing the query to skip module 1 and collect the
relevant data from module 1.1.
