To Add record in Database

[smugcool]

Hi,

I have created a form in Visual basic 6.0 for adding/updating the change request made by various users.

Well i am able to update the record through my code in access database.

Can anyone tell me what code should i use to Add record in the database, i also want the new record which will be added in the access database is having some unique no like CRC-CC-date/month/year-incremental number?

I mean as soon anyone will hit the add record form should become compltly blank and with a unique no as per above format.And same has to be updated in the database.

Below is my code, where i have reached

Private Sub Form_Load()
strMyDB = App.Path & "\" & "MyDB.mdb"
txtSearch.Text = DefaultSearchTe xt
End Sub

Private Sub cmdSearch_Click ()
'Search for a client

'Start query

'Build filter requiring all words entered
' to be in username, name_first, or name_last field
For iWord = 0 To UBound(arWords)

Kindly help me. Thanx in advance.

You never point what you had tried for insert query.

let cn is your connection

Dim strSql as string
 
strSql="Insert into <Table Name> (field1,field2,field3) values("  & value1 & ", "  & value1 & ", "  & value1 & ")".
cn.Execute strsql

actually i tried few things but didn't work.

I have the tried the above code which is given by you, but it is also not working i am geting error of Sub/function not defined,

Private Sub CmdAdd_Click()
Dim strSql As String
Dim cn As New ADODB.Connectio n
Dim n As String
Where n = 0
strSql = "Insert into <clients> (txtUsername),v alues(CRC-CC-today()-n)"
strSql = "Insert into <clients> (txtUsername),v alues(CRC-CC-today()-n+1)"
cn.Execute strSql
End Sub

Above is the code. Plz go thru it if its correct or changes required.

cn.Execute strSql
End Sub

I think CRC-CC-today() is an VB method and also n.
so the code will be..

strSql = "Insert into clients (txtUsername) values(" & CRC-CC-today()-n & ")"
cn.Execute strSql
    strSql = "Insert into clients (txtUsername) values('" & CRC-CC-today()-n+1 & "')"
    cn.Execute strSql

For value type the single quote will not be there
it will appear for String and date time type data.
