Re: mysql remove last char

You can use (in MySQL):

Code: Select all

SELECT column SUBSTRING(column,1,CHAR_LENGTH(column)-1) AS column_part FROM table;
You can also do an update and change all the data.

Code: Select all

UPDATE table SET column=SUBSTRING(column,1,CHAR_LENGTH(column)-1) FROM table WHERe column Like '%,' ;
