I’m working with a database table that has a column called ‘photo_name’. I made a mistake during my last data insert operation and forgot to add the file extensions to all the image names I entered. All these files are supposed to have ‘.jpg’ extensions.
I need help with updating the ‘photo_name’ column for these specific records. I can identify the affected rows using their ID numbers. What’s the best approach in SQL Server to add the ‘.jpg’ extension to the end of the existing values in this column?
I’m looking for a simple UPDATE statement that can handle this task efficiently.
Interesting situation! What if some photo names already have extensions? You might want to check first with WHERE photo_name NOT LIKE ‘%.%’ so you don’t end up with weird stuff like ‘image.png.jpg’. What’s ur current data look like?
CONCAT works great for this. Just use UPDATE table_name SET photo_name = CONCAT(photo_name, ‘.jpg’) WHERE id IN (your_specific_ids). CONCAT handles NULL values better than the regular concatenation operator, which is handy. I ran into something similar when migrating old data with missing file extensions. Before you run the update, test it first: SELECT id, photo_name, CONCAT(photo_name, ‘.jpg’) AS new_name FROM table_name WHERE id IN (your_ids). This way you can check the results before making permanent changes.
u can do an UPDATE like this: UPDATE table_name SET photo_name = photo_name + ‘.jpg’ WHERE id IN (your_id_list). the + is the concatenation op in sql. don’t forget to back up ur data first, just in case!
