    Hello
    If i have the following SQL code that i run, how can i make it so that if i run it again it wont to the same changes to the collumns that is already changed one before? my idea was to add a collumn to the rows with a value to check if the code has been run maybe? if yes, how can i make so that the code skips the row if the collumn value is set to 1, a value of 0 means that the code has not been run there yet, let's say we call this collumn "changecheck". also, if "changecheck" do not yet exist for a row, it should be added and treated as if it has not been changed yet, can this be done ? uf yes, i hope someone could help me :)

    UPDATE<yourTableName>SET name = CONCAT(name,'_',original_width,'x',original_height);

    You can use
    UPDATE<yourTableName>SET name = CONCAT(name,'_',original_width,'x',original_height) WHERE changecheck = 0; 
    Code (markup):
