Dim dt As Date
dt = FormatDateTime(DatePurchaseFrm.Value, DateFormat.ShortDate)

PurchaseSql = "Select * from PUrchase where PurchaseDate => '" & txtDate.text &"'"

PurchaseConn.ConnectionString = "Provider=Microsoft.jet.oledb.4.0; Data Source=" & Pth & "\DisplayCenterData.mdb; User Id=admin; Password=;"

PurchaseDa = New OleDbDataAdapter(PurchaseSql, PurchaseConn)

PurchaseDs = New DataSet
PurchaseDa.Fill(PurchaseDs, "DisplayCenterData")
PurchaseDt = PurchaseDs.Tables("DisplayCenterData")

PurchaseCmb = New OleDbCommandBuilder(PurchaseDa)

PurchaseDa.InsertCommand = PurchaseCmb.GetInsertCommand

'' PurchaseSql = "Select * from PUrchase where PurchaseDate => '" & DatePurchaseFrm.Value.ToString("dd-MM-yyyy") & "' order By PUrchaseID"

''PurchaseSql = "Select * from PUrchase where PurchaseDate =@05/04/2010 order By PUrchaseID"

''PurchaseSql = "SELECT * FROM purchase WHERE PUrchaseDate between '" & Format(Me.DatePurchaseFrm.Value, "dd/dd/yyyy") & "' AND '" & Format(Me.DatePurchaseTo.Value, "dd/MM/yyyy") & "'"

''PurchaseSql = "Select * from PUrchase where PurchaseDate ='" & DatePurchaseFrm.Value & "' order By PUrchaseID"

''PurchaseSql = "Select * from PUrchase where CONVERT(CHAR(10),PurchaseDate) =>" & DatePurchaseFrm.Value.ToString("dd-mm-yyyy") & " order By PUrchaseID"

''PurchaseSql = "SELECT * FROM Purchase WHERE PurchaseDate>= DateValue('" & DatePurchaseFrm.Value & "')" & " ORDER BY PurchaseID"

''PurchaseSql = "select * from Purchase"
''PurchaseSql = "Select * from PUrchase where CONVERT(CHAR(10),PurchaseDate,103) BETWEEN '" & DatePurchaseFrm.Value.ToString("dd/MM/yyyy") & "' AND '" & DatePurchaseTo.Value.ToString("dd/MM/yyyy") & "' order By PUrchaseID"
''PurchaseSql = "Select * From Employees Where HireDate Between #1/1/1990# and #12/31/2010#"


txtPurchaseID.DataBindings.Add("text", PurchaseDt, "purchaseID")
txtCompanyID.DataBindings.Add("text", PurchaseDt, "companyID")

So once you've built up the sql

by Tony Hopkinson In reply to i want to search date usi ...

What does it look like?

Right or wrong?

What do you mean by doesn't work, doesn't find the values you expect, or doesn't like your SQL?

A tip if you are going to do it this way, choose a universal date format.
yyyy-MM-dd always works.

Try something like this

SQL = "Select * From Table Where DateValue = @SearchDate"
Put that in the command then
Create a Parameter (oleDBParameter)?
name of "SearchDate", Type dbType,date, Value of DatePurchaseForm.Value
Add that to the command , then call fill.

You'll have to muddle through help and intellisense for teh exatct doings, I do C# and avoid access...

No more conversions to strings, and no more developing bad habits like building sql from user input. That's how SQL Injection attacks happen.
