Meta-SQL Use (with reference to PeopleSoft)
Meta-SQL expands to platform-specific SQL substrings, causes another function to be called, or substitutes a value. Meta-SQL constructs are used in functions that pass SQL strings, such as the following:
Meta-SQL Element
Types There are three types of meta-SQL elements:
Meta-SQL Placement Considerations: Not all meta-SQL can be used by all programs. Some meta-SQL can be used only in Application Engine programs. Other meta-SQL can only be used as part of a SQL statement in a SQL or dynamic view. The following table lists available meta-SQL elements and where each element can be used.
If a meta-SQL construct, function, or meta-variable is supported in PeopleCode, it is supported in all types of PeopleCode programs; that is, in Application Engine PeopleCode programs (actions), component interface PeopleCode programs, and so on.
Note: Even if a meta-SQL element is used in PeopleCode, you cannot use meta-SQL like a built-in function. You can use meta-SQL in the SQLExec function, the Select method, the Fill method, and so on. Note: Meta-SQL is not available in SQR
