This MSAccess tutorial explains how to perform an update to a table using VBA code in Access 2003 (with step-by-step instructions). Only use stored queries when queries are going to be used in more than two locations in the forms or modules.MS Access 2003: Perform an update with VBA code The way most developers do this is with a stored query often resulting in dozens, if not hundreds, of queries to look through in the database. This makes seeing what is going on much easier and also aids in debugging since you can have a debug.print sqltext statement to see exactly what is going on. One helpful feature included in this example is the construction of the SQL statements within the code. ‘ report code follows – but not important for this example Perhaps one of these orders is being edited?” MsgBox Err.Description & vbCrLf & ” Error clearing out Temp table. ‘- error handler for 3rd Access transaction -– Set rst2 = db.OpenRecordset(sqltext, dbOpenDynaset) Sqltext = “select order_detail_id from T_Mnu_Odr where ” & _ ‘ clear out temp table for this manufacturer Perhaps one of these orders is being editted?” MsgBox Err.Description & vbCrLf & ” Error in updating ” & _ Set rst = db.OpenRecordset(sqltext, dbOpenDynaset) “INNER JOIN T_Mnu_Odr ON M_Mnu_Odr.Order_Detail_ID = ” & _ “M_Odr_Dtl.Order_Detail_ID = M_Mnu_Odr.Order_Detail_ID) ” & _ ” FROM (M_Odr_Dtl INNER JOIN M_Mnu_Odr ON ” & _ “M_Mnu_Odr.Manufacturer_Order_ID as Man_ID” & _ Sqltext = “SELECT M_Odr_Dtl.Manufacturer_Order_ID as Order_Man_ID, ” & _ ‘ update the M_Odr_Dtl.manufacturer_order_id to the newly “and faxes have NOT been marked as done.” MsgBox Err.Description & ” An error was encountered will attempting to insert ” & _ ‘ encountered error in first transaction so rollback transactioin Rst3.MoveFirst ‘ goto the first record that needs to be inserted Set rst4 = db.OpenRecordset(“M_Mnu_Odr”, dbOpenDynaset) ‘now open up the m_Mnu_Odr table to insert new recs. Set rst3 = db.OpenRecordset(sqltext, dbReadOnly) ‘ we don’t need VB transaction processing on the next recordset because we “#” & Thedate & “# as tdate FROM T_Mnu_Odr ” & _ Sqltext = ” SELECT T_Mnu_Odr.Manufacturer_ID, ” & _ ‘ start by getting the list of order details to insert into M_Mnu_Odr table ‘-– setup for 1st VBA transaction processing loop -– MsgBox Err.Description & vbCrLf & ” The date you entered may not be in a standard ” & _ MsgBox “This function has been canceled.” StrInput = InputBox(“Today’s Date or enter another date”, “Faxed Date”, myformat)

Ideally I would have indented the nested transactions but I don’t have enough room on the screen to make it readable. The key to all of this is the nesting of the VB BeginTrans instructions and the VB Rollback code in each of the error handlers. Then we update a field in the M_Odr_Dtl table with each of the newly create M_Mnu_Odr records, creating a link between these two tablesĬlear out the appropriate records in the T_Mnu_Odr table Insert each faxed order into our M_Mnu_Odr table User is asked for a faxed date – usually this is today The transaction process goes as follows: (Note that a procedure for faxing the orders has already taken place) M_Mnu_Odr – a table that stores the details of each order that has been faxed to the manufacturers. T_Mnu_Odr – a temporary table used to selectively send out Widget orders to any of several Widget manufacturers. There are basically three tables involved in our Access transaction processing tutorial: The setup for this example is as follows: We have a form which lists customer orders of Widgets.These orders get faxed to the manufacturer and then we want the program to update and clear out various tables to indicate that the faxes have been done and when they were done. This Access transaction processing example shows you how to assure that all or no tables get updated in a multi-table transaction. Access Transaction Processing Rollback Begintrans CommitTrans
