JJM50 Posted October 7, 2021 Share Posted October 7, 2021 Currently I have a database with the following parameters and entry: https://www.sqlservercentral.com/wp-content/uploads/hm_bbpui/3938402/wimjr5jobcrtsgm158e69cru722hkx4o.png Now I want to fill the column status_from in this particular entry with the id 1 with a substring of the action column. Which is basically I want to fill my status_from column with a word that comes after from and before to of the action column. To achieve this I've tried using the following statement: INSERT INTO crm_logs2(status_from) SELECT status_from WHERE id='1' VALUES (substring_index(substring_index(action, 'from', -1),'to', 1)) But doing this gave me the following error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'VALUES (substring_index(substring_index(action, 'from', -1), ...' at line 1 Quote Link to comment https://forums.phpfreaks.com/topic/313892-inserting-a-substring-value-into-an-already-existing-entry/ Share on other sites More sharing options...
Barand Posted October 7, 2021 Share Posted October 7, 2021 Firstly, I doubt anyone is clicking a link from a first-time poster. Second, what you are doing, updating with parts of a column, is indicative of problems in the database design. What is the structure of those two tables and what does the data look like in the relevant columns? 1 Quote Link to comment https://forums.phpfreaks.com/topic/313892-inserting-a-substring-value-into-an-already-existing-entry/#findComment-1590756 Share on other sites More sharing options...
