Function reference

Informatica provides a transformation language that includes SQL-like functions to transform source data. Use these functions to write expressions and create user-defined functions.

Expressions modify data or test whether data matches conditions. For example, you can use the AVG function to calculate the average salary of all the employees or the SUM function to calculate the total sales for a specific branch. You can create a simple expression that only contains a single function, such as AVG. You can also write complex expressions by nesting functions within functions.

If you create expressions within a mapping in SQL ELT mode, use your cloud data warehouse's native functions and expression syntax instead of Informatica functions and expression syntax. For more information about the native functions and expression syntax, see the documentation for your cloud data warehouse.

User-defined functions use expression logic to build complex expressions. You can include them in other user-defined functions or in expressions. For more information about user-defined functions, see
