When you write Insert statements, it can be difficult to accommodate the possible values end users might enter into a textbox. The most common task is replacing single quotes with double quotes. However, parameterized queries provide two benefits: You do not have to parse data entered by users?except for business rules; and SQL Server 7.0 immediately caches the SQL statement:
Dim cmd As ADODB.CommandDim prm As ADODB.ParameterSet cmd = New ADODB.CommandSet prm = New ADODB.ParameterWith cmd .ActiveConnection = CONNECT_STRING .CommandText = "INSERT INTO employees " & _ "(name) VALUES(?)" .CommandType = adCmdText Set prm = .CreateParameter(, adChar, _ adParamInput, 50, Me.txtName.Text) .Parameters.Append prm .ExecuteEnd WithSet cmd = NothingSet prm = Nothing
