Use TEXTPTR to locate the text column, copy, associated with au_id 486-29-1786 in the author's blurbs table.

The text pointer is put into a local variable @val and supplied as a parameter to the readtext command, which returns 5 bytes, starting at the second byte (offset of 1).

SELECT @val = TEXTPTR(copy)
FROM blurbs
WHERE au_id = "486-29-1786"
READTEXT blurbs.copy @val 1 5 ;
