How to remove part of string in mysql?

Question

In one table of my database I have strings which looks like this one:

sometext-othertext

How to remove the text including dash with SELECT

Answer 1

have two ways to use troubleshooting this, if you like to display all (only just remove "-" symbol, i recommended use this because have more speed:

SELECT REPLACE('sometext-othertext','-','');

that syntax change text "-" to "" (empty text because you want just remove that)

if you want to display only part one (ex :sometext) or just part two (ex :othertext) you can use this, for spliting string:

SELECT SUBSTRING_INDEX('sometext-othertext', '-', 1);
