Indicator variables can be used with main variables intended for I/O, although certain indicator variables cannot be used for input (for example, those appearing in a WHERE clause).

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

Indicator variables are documented in SQL Stored Procedures and Embedded SQL (B035‑1148).
