MySQL Last Insert ID

after you call update just query the adoRs("NameOfIDColumn").Value

Well, I don't know about MySQL but in SQL Server you can do the insert inside a stored procedure and have the stored procedure return the ID. Like:

CREATE PROC cp_Insert_and_return_ID
AS
BEGIN
     INSERT table_name (Field1) VALUES('Value')
     SELECT @@IDENTITY AS ID
     RETURN
END
GO

In your sql try:

INSERT INTO tablename (id, stuff) VALUES(tablenameSeq.nextval, stuffvalue)
RETURNING ID INTO v_lastupdateID;

After the addnew or update call check the auto id field, it may be populated with the next ID

.Update
AutoID = .Fields("ID")

I have not tested this, but it  work.  If not you can retrieve it using a SQL statement.  Here is the function I use...

Public Function ReturnLastAutoNumber(sTableName As String) As Long
   
    Dim rstTemp As adodb.Recordset
     
    Set rstTemp = objDBConn.Execute("select max(IDENTITYCOL) as Col from " & sTableName)

    ReturnLastAutoNumber = rstTemp!Col
   
    rstTemp.Close
   
End Function

NOTE: If you have multiple users adding records this could return the ID of a record that was added by another user.

gencross, Thanks a million!! I had to use the select max statement...but I will have multiple people adding records so what would you recommend.  Here is what I ended up with.

 
Set adoLog3000Rule = New Recordset
    adoLog3000Rule.Open "SELECT MAX(Log3000ID) as col FROM Log3000", _
      db, adOpenKeyset, adLockOptimistic, adCmdText
    adoLog3000Rule.MoveFirst
    gbl_Highlighted_Log3000ID = Val(adoLog3000Rule.Fields(0))
     

In the past with multiple users I have added a record with a date time stamp and user id then select the record from the table using the date time stamp as well as the user who entered the record.

Here is an example of using just a date time, but you can add a user id to it.  Alternatively you can select the record using other unique data.  You would think there is an easier way to do this, but there isn't:)

sNow = Now

.AddNew
.DateAdded = sNow
.Update

Retrieve ID...

sSQL = "SELECT ID FROM Table WHERE DateAdded = '" & sNow & "'"

Let me know if this makes sense.

just open a new recordset using the same connection w/ this sql: "select last_insert_id()"

you can also do "select last_insert_id() from <table>"

bobbit, multiple users are adding records at the same time.  Is using the last_insert_id function going to return the ID of the particular record that was added or the ID of the last record that was added?

I tried the last_insert_id() function and it didn't work...is this function suppose to work with mysql, odbc, VB, and ado combination?

> multiple users are adding records at the same time

from mysql docs:

LAST_INSERT_ID([expr])
Returns the last automatically generated value that was inserted into an AUTO_INCREMENT column. See section 8.4.3.126 mysql_insert_id().
mysql> SELECT LAST_INSERT_ID();
        -> 195

The last ID that was generated is maintained in the server on a per-connection basis. It will not be changed by another client. It will not even be changed if you update another AUTO_INCREMENT column with a non-magic value (that is, a value that is not NULL and not 0). If you insert many rows at the same time with an insert statement, LAST_INSERT_ID() returns the value for the first inserted row. The reason for this is so that you it makes it possible to easily reproduce the same INSERT statement against some other server. If expr is given as an argument to LAST_INSERT_ID(), then the value of the argument is returned by the function, and is set as the next value to be returned by LAST_INSERT_ID().

Here is what works...

adoLog3000Rule.Open "SELECT MAX(Log3000ID) as col FROM Log3000", _
'            db, adOpenKeyset, adLockOptimistic, adCmdText

But is there anyway to add the RecordAdded col to this same select with a WHERE clause also to compare against the worktime.
For example:

  adoLog3000Rule.Open "SELECT MAX(Log3000ID) as col from Log3000, Log3000.RecordAdded WHERE RecordAdded = " & "'" & worktime & "',""" _
            db, adOpenKeyset, adLockOptimistic, adCmdText


Can anyone help with the syntax of this....

> mysql, odbc, VB, and ado combination?

i see no reason why it wouldn't...
mysql is the only thing that needs to understand it.

You should not need to use the max function in this statement.  Try this...

(You will probably only want to open the recordset forward only also)

set adoLog3000Rule = db.Execute("SELECT Log3000ID as col from Log3000 WHERE RecordAdded = " & "'" & worktime & "'"

> I tried the last_insert_id() function and it didn't work
what was the error message?

The error was "ODBC driver manager driver does not support this parameter"  This was my statement...

adoLog3000Rule.Open "SELECT LAST_INSERT_ID()", db, adOpenForwardOnly, adLockOptimistic, adCmdText

THANKS TO EVERYONE FOR ALL YOUR HELP... I HAVE LEARNED LOTS!  SETTING THE BIGINT TO INT OPTION FIXED IT.  I WAS ABLE TO USE THE LAST_INSERT_ID FUNCTION.
