Table Functions
Table functions are part of the predefined functions . The following table functions are possible:

lines - Row function

line_index - Index function

Furthermore, the string function
concat_lines_of expects an internal table as an argument; the predicate function line_exists expects a table expression.

Note
Table functions can be used in suitable
operand positions , for example directly as an operand of arithmetic or relational expressions .
