For structured UDTs only, .ALL specifies that the individual attribute values for a specified table or column name are to be returned.
ANSI Compliance
.ALL is a Teradata extension to the ANSI SQL:2011 SQL standard.
.ALL Operator and Structured UDTs
If a column has a structured UDT data type, then the values of its individual attributes are returned when you specify the .ALL option.
If you specify the .ALL operator using either of these syntaxes, but there is no structured data type column in the specified table set, the database disregards the specification:
- *.ALL
- table_name.*.ALL
If you specify this syntax, but the specified column does not have a structured UDT type, the specification is disregarded:
column_name.ALL
