Operator not defined error? - sql

Question

I am trying to update a record but I get the error: Operator '=' is not defined for type 'Date' and type 'Integer'. How can I fix this?
If Me.txt_Team.Tag = 0 Then
sSQL = "INSERT INTO FixtureandResultsDatabase (Fixture_Date, Team, Ground, Score)"
sSQL = sSQL & " VALUES(?, ?, ?, ?)"
cmd.CommandText = sSQL
Else
sSQL = "UPDATE FixtureandResultsDatabase set Fixture_Date = #Fixture_Date, Team = #Team, Ground = #Ground, Score = #Score WHERE ID = #id"
cmd.CommandText = sSQL
End If
cmd.Parameters.Add("#Fixture_Date", OleDbType.Date).Value = Me.dtp_Date.Text
cmd.Parameters.Add("#Team", OleDbType.VarChar).Value = Me.txt_Team.Text
cmd.Parameters.Add("#Ground", OleDbType.VarChar).Value = Me.cb_Ground.Text
cmd.Parameters.Add("#Score", OleDbType.VarChar).Value = Me.txt_Score.Text
If Me.txt_Team.Tag <> 0 Then
cmd.Parameters.Add("#ID", OleDbType.Numeric).Value = Me.txt_Team.Tag
End If
cmd.ExecuteNonQuery()
If Me.txt_Team.Tag = 0 Then
cmd.Parameters.Clear()
cmd.CommandText = "Select ##Identity"
Me.txt_Team.Tag = cmd.ExecuteScalar()
End If
MsgBox("Database has been updated.")
conn.Close()

Fix it like this
Instead of
cmd.Parameters.Add("#Fixture_Date", OleDbType.Date).Value = Me.dtp_Date.Text
Do
cmd.Parameters.Add("#Fixture_Date", OleDbType.Date).Value = Me.dtp_Date.Value
You should post your table structure [sp_help 'tableName']. You obviously have date field but you trying to set value [object] to string - Me.dtp_Date.Text.
On another note - get rid OleDB ASAP - use SqlClient. oleDb will be decommissioned soon. Also, you can use Output Inserted.Id in your update and insert with ExecuteScalar instead of ExecuteNonQuery. It will return your identity all in one statement - instead of Select ##Identity.
