The standard Multiply (*) operator is supported, generating expression * expression. Within Teradata, this operator automatically converts numeric operands to the expected result type before they are applied. Character type data is converted to FLOAT if possible before being applied. Refer to the chapter titled Binary Arithmetic Result Data Types in SQL Functions, Operators, Expressions and Predicates, B035-1145, for information on the resulting data types and other specific usage information. When dragging a Multiply into a variable, the following tree element is created.
Variable Creation > Input > Variables: SQL Elements pane - Arithmetic > Multiply
Columns and/or other expressions can be moved over the (empty) branches of the tree.
There are no special properties for the Multiply function.
