Indicator variables can be used with main variables intended for I/O, although certain indicator variables cannot be used for input.

For more information on indicator variables, see SQL Stored Procedures and Embedded SQL (B035‑1148).

PP2 uses indicator variables to handle nulls sent to or returned from the Teradata Database, as well as for truncation of a character or byte string when placed into the corresponding main variable.
