what does rs.Fields(0) mean? (ADODB) VBA

dim rs As ADODB.Recordset
...
...
...
capture_id = rs.Fields(0)

wha开发者_C百科t does .Fields(0) mean?

---

the first column from the recordset (0) is the first (1) is the second etc etc

example, if this is your query

select LastName, FirstName 
from YourTable

In this case s.Fields(0) would return column LastName and rs.Fields(1) would return column FirstName

---

It's pulling the first column from the current row in the result set.

Fields(x) lets you access fields by a numerical index starting at 0.

Edit:

Example:

If the result set has two columns: foo and bar..

rs.Fields(0) would return the value of column foo,

and

rs.Fields(1) would return the value of column bar.

I would NEVER, EVER use this syntax. This is dependant on the query always having the same field in the first position.

Furthermore this would only save a minute amount of time. (As in milliseconds if not less.)

Please, for the love of God, per proper programming practice, change that to use the field name. This almost, but not quite, belongs on the www.dailywtf.com website.
