How to append and pop values in MySql
MySQL SUBSTRING() returns a specified number of characters from a particular position of a given string.
UPDATE `lockers` SET `currpass` = SUBSTRING(`currpass`, 1, 8)
this would cut down the string in table currpass to only its first 8 characters
to strip off only last 2 characters
UPDATE `joo_categories` SET `title` = SUBSTRING(`title`, 1, CHAR_LENGTH(title) - 2) WHERE `title` LIKE '%∞%'
UPDATE messages SET message = CONCAT(message,'new text to add')where user_id =1; OR UPDATE `rqktr_content` SET `title` = SUBSTRING(`title`, 22) where `title` LIKE 'Watch Naruto Shippuden Episode ___'
If there is a chance that the field may contain a null value, the following works:
UPDATE tb_messages SET message =CASE WHEN LENGTH(message)>0THEN CONCAT(message,',','New message content') ELSE'New message content' END WHERE user_id =1
UPDATE `rqktr_content` SET `title` = CONCAT('Watch ', title) WHERE `title` LIKE 'Fairy Tail Episode ___' ORRR UPDATE `rqktr_content` SET `title` = CONCAT('Watch Naruto Shippuude', title) WHERE `title` LIKE 'n Episode ___'
Hope it helps 🙂
You really make it appear so easy along with your
presentation but I find this matter to be actually one thing which I believe I’d by no means understand.
It seems too complicated and very broad for me. I’m having a look forward
to your subsequent post, I will attempt to get the cling of it!
