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 (â€śBOOKSâ€ť);
ot_books2 = CE_COLUMN_TABLE (â€śBOOKSâ€ť, [â€śTITLEâ€ť, â€śPRICEâ€ť, â€śCRCYâ€ť]);
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.
