When querying a View in Intelligence Central or when writing a cross-connection query, Toad allows you to use Intelligence Central functions instead of the usual database-specific functions. Toad then translates the function into the database specific syntax, if necessary.
This method can be convenient if you want to use the same query against two different database types. This method can also be useful when writing cross-connection queries.
Note: This feature is provided as an optional method. For best results when creating a cross-connection query, use the Query Builder to generate the correct syntax.
You can use the Intelligence Central functions in the following situations:
You can use Intelligence Central functions in the situations described above against the following database types:
The following functions can be used in place of platform-specific functions in queries against the supported data sources listed in this topic.
