In SQL, how can I remove the first 4 characters of values of a specific column in a table? Column name is
Student Code and an example value is
I want to remove first 4 chars from my table for all records
Please guide me
This question is related to
SELECT RIGHT(MyColumn, LEN(MyColumn) - 4) AS MyTrimmedColumn
Edit: To explain, RIGHT takes 2 arguments - the string (or column) to operate on, and the number of characters to return (starting at the "right" side of the string). LEN returns the length of the column data, and we subtract four so that our RIGHT function leaves the leftmost 4 characters "behind".
Hope this makes sense.
Edit again - I just read Andrew's response, and he may very well have interperpereted correctly, and I might be mistaken. If this is the case (and you want to UPDATE the table rather than just return doctored results), you can do this:
UPDATE MyTable SET MyColumn = RIGHT(MyColumn, LEN(MyColumn) - 4)
He's on the right track, but his solution will keep the 4 characters at the start of the string, rather than discarding said 4 characters.
