A SQL Element List generates a comma separated list of the SQL expressions in the Expressions folder underneath it. If the SQL Element List is used as the operand of a SQL operator it will automatically be enclosed in parentheses. Otherwise, a separate Parentheses element may be used above it if required in another context.
When dragging a SQL Element List element into a variable, the following tree element is created.
Variable Creation > Input > Variables: SQL Elements pane - Other > SQL Element List
There are no special properties of the SQL Element List.
