Question

Is there a MySQL function to easily insert a character or characters into the value of a varchar column?

I want to set the following text:

B U 1 U 09 2011 Segs 1, 3 - 10 24 hours

To

B U 1 U N 09 2011 Segs 1, 3 - 10 24 hours

Answer 1

To SELECT a value with it you can use:

select concat(left(col, 8), 'N ', substring(col, 9))
from table1

If you want to UPDATE you can use:

update table1
set col = concat(left(col, 8), 'N ', substring(col, 9))
