datatype mismatch in criterion expression error

Hi guys,

I keep getting a "Data type mismatch in criterion expression" error.
I cant figure out whats wrong, ive googled but still cant seem to find the problem.

Code:

---

Private Sub cmdSave_Click()

    c.Execute ("Update Addresses set buyerbookdate='" & txtBuyerbookdate.Value & "',buyerbooktime='" & txtBuyerbooktime.Value & "',bbratios='" & txtBuyerRatioS.Text & "' where orderno='" & Combo1.Text & "';")
    MsgBox "Records Added Successfully!", vbInformation, "Save"

Exit Sub
ErrHand:
    MsgBox Err.Description, vbCritical, "Error"
End Sub

---

Any help would be greatly appreciated!

i suspect buyerbookdate field is a date/datetime type and on your update query you're setting a string type, also the same case with buyerbooktime , what are the types of these fields (buyerbookdate and buyerbookdate) in your database.

for date field use #02/01/2011# instead of '02/01/2011'

e.g.

"Update Addresses set buyerbookdate=#" & txtBuyerbookdate.Value & "#, ...

What is the field type for orderno? If it is not text remove the single qoutes around Combo1.Text. As for the date suggestion in #2 if you are using access db ignore that otherwise follow it.

thanks for your replies. the orderno field is a text field, i am using an access database so how do i proceed from here? :)

The I would have you post the exact SQL that is being generated here. Also the field names in the table and thier data types.

Do you know how to get the actuall SQL that is being generated and run?

is the field bbratios of type string? if not remove " ' " single quote arround the txtBuyerRatioS.Text

buyerbookdate and buyerbooktime(fields) are date/time fields in access.
no, i dont know how to get the actual sql... ? :confused:

Set a breakpoint. step though the code line by line. Once you get to the line after you generate the SQL statement you can right click on the var. Once you do that you should get a menu to display the value. Also you can set watchs on variables that will let you know when on changes and what it contains after the change.

gosh, i have a lot to learn, ive never use breakpoints and watches and stuff before, i just run the program and wait for errors (really terrible i know)

You really need to learn to use breakpoints it is the minimum you need to be able to debug a program

off to google i go! thanks.
Any pointers on the initial problem ?

You havae issues in the SQL Statement. Either a field in named wrong/spelled worng or the datatype is not passing what you expect.

thanks for you help , much appreciated.
