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 (“BOOKSâ€);
ot_books2 = CE_COLUMN_TABLE (“BOOKSâ€, [“TITLEâ€, “PRICEâ€, “CRCYâ€]);
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.
