It's the offset of field in row.

Quote:

SELECT 'abc', 1, 0x424344, "def" FROM dual

value of:
field with offset 0 - "abc"
field with offset 1 - 1
field with offset 2 - 0x424344 (aka "ABC")
field with offset 3 - "def"

Let's say you have table with fields id, name, nick

Quote:

SELECT * FROM yourtable

field with offset 0 - id
field with offset 1 - name
field with offset 2 - nick

#e: This will return those field values
