LAST() - Fetches the last element in a collection of values. | ||
|
||
A scalar function returns a single value based on the input value. | ||

||
LEN() - Calculates the total length of the given field (column). | ||
UCASE() - Converts a collection of string values to uppercase characters. | ||
LCASE() - Converts a collection of string values to lowercase characters. | ||
MID() - Extracts substrings from a collection of string values in a table. | ||
