Add record on button click only

问题:

I have a form that has the 'data entry' property set to yes. It is bound to a table. When I start filling in the form it automatically saves it. I do not want this to happen. I only want the form to save to the table when I press a button. Any easy way to do this? w/o vba. If i can only do this with vba let me know how to do it that what.

The best way to do this is with an unbound form. When the user clicks save, you can run a query to update your table from the controls.

Using a recordset

 Dim rs As Recordset
 Set rs=CurrentDB.Openrecordset("MyTable")

 rs.AddNew
 rs!Field1 = Me.Field1
 rs.Update

If you wanted to update a record where you already knew the primary key, you could say:

 Dim rs As Recordset
 Set rs=CurrentDB.Openrecordset("SELECT * FROM MyTable WHERE ID=" & Me.txtID)

 rs.Edit
 rs!Field1 = Me.Field1
 rs.Update

Using a query that you have created in the query design window

SQL for the query

 INSERT INTO MyTable (Field1) 
 VALUES ( Forms!MyForm!Field1 )

VBA

This will give a warning

 DoCmd.OpenQuery "MyQuery"

This will not

 CurrentDb.Execute "Query2", dbFailOnError

You could also use dynamic SQL or a query with parameters that you assign in code.
