Let’s say you have a set of string values (such as values in a column) and you want to remove the last character. But, the string values are all different lengths. How can you do that?
Use a combination of the LENGTH and SUBSTR functions.
First, use LENGTH to find the length of a string. Then, find use SUBSTR to get the entire string except for the LENGTH minus 1.
SELECTSUBSTR(your_column, 0, LENGTH(your_column) - 1)FROM your_table;This will remove the last character from your string. It’s great for removing trailing slashes or other characters from the end of a string.
