This function is only available when connected to a Teradata database.
The Try Cast function attempts to cast the argument from its base data type to another (selected from the Properties dialog). If the casting attempt fails, the Try Cast function returns a result of NULL. When dragging a Try Cast function into a variable, the following tree element is created.
The Try Cast Properties dialog automatically appears.
Select a data type to attempt to cast to from the Data Type drop-down menu and enter any pertinent data type and/or attribute information in the appropriate field. The Resulting SQL field will display the generated SQL to be executed when run.
