CHAR(' ',0) RETURNS EMPTY STRING INSTEAD OF NULL IN VARCHAR2 ENABLED DATABASE. | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 | |
Problembeschreibung: | |
In a VARCHAR2 enabled database, an assignment of an empty string value to a CHAR, VARCHAR, GRAPHIC or VARGRAPHIC should produce a NULL value. However, if a string literal is not empty, consists of all blanks is passed as an argument to the scalar functions CHAR, VARCHAR, GRAPHIC or VARGRAPHIC, and has a specified length of 0, then an empty string is returned instead of the expected NULL. The returned string might look like the following sample: values char(' ',0) 1 - 1 record(s) selected. | |
