CE_COLUMN_TABLE operator provides access to an existing column table. It takes the name of the table and returns its content bound to a variable.

Example:
ot_books1 = CE_COLUMN_TABLE (“BOOKS”);
ot_books2 = CE_COLUMN_TABLE (“BOOKS”, [“TITLE”, “PRICE”, “CRCY”]);

This example only works on a column table and does not invoke the SQL processor. It is semantically equivalent to the following:

ot_books3 = SELECT * FROM books;
ot_books4 = SELECT title, price, crcy FROM books;
The function that provide data source access does not allow renaming of attributes.
