| X |
Extracts the n leftmost characters from a string. The format appears below:
XLEFT(x, n)
The parameter x is any expression that evaluates to a character string, and the parameter n is a positive integer indicating the number of characters to extract. For example, suppose you want to extract the area code from all customer phone numbers, you can use the query:
SELECT company, XLEFT(phone, 3) FROM customer
If n is longer than the string extracted, the string is right padded with spaces until it is n characters long.
For example:
SELECT XLEFT(color, 10)||pname FROM part
