Hi is it possible to cut string like this:
String in "data" columns: ,123,456
Cut the first character i.e "," (comma).
So the query is something like:
Update users set data = cut first string...

MySQL SUBSTRING() Function The SUBSTRING() function extracts a substring from a string (starting at any position). Note: The SUBSTR() and MID() functions equals to the SUBSTRING() function.
SELECT LEN(column_name) FROM table_name; And you can use SUBSTRING or SUBSTR() function go get first three characters of a column.
UPDATE users SET data = SUBSTR(data, 2);
This will iterate through all rows in users and replace data with itself minus the first character.
