Updating records in ms access

If, as usually is the case, you use the Move Next in a loop as below this test is done with When you use the Delete method, the Microsoft Access database engine immediately deletes the current record without any warning or prompting.Deleting a record does not automatically cause the next record to become the current record; to move to the next record you must use the Move Next method.The adding of a record requires: recordsetfindandedit Check out this to see how the code is created with just a few menu selections Moving through a recordset changes what is the 'current' record.The most direct way to move to a specific record is using the prefix" where field is an indexed field in the underlying base table and prefix is a prefix search string (for example, "ART*" ).If you are unable to find common fields between your form and subform, you can always place code on the "On Current" event of the form to refresh the subform. Scroll down until you find the property called "On Current".Then click on the button with the three dots to the right of this property.It turns out that Access Jet Engine does not support count(distinct xxx) syntax, which is supported by all major DBMS systems such as SQL Server, Oracle, My SQL, etc.The solution to this problem is to write a sub-query in the FROM clause to retrieve all the qualified distinct records, then in the outer query in the SELECT statement, do a count for the number of records returned by the sub-query.

The code below opens a recordset taken from a table in the current database on a query or attached table Access defaults the Type property to db Open Dynaset.

However, Access kept giving me the syntax error message shown below.

Syntax error (missing operator) in query expression 'count(distinct Reports To)'.

In this example, we've selected the Order ID fields. Now when you return to the subform properties window, you should see the "Link Child Fields" and "Link Master Fields" properties filled in.

Now, Access will be refresh your subform whenever the record in the main form changes.
