Ms access update query not updating table

Rated 4.69/5 based on 783 customer reviews

Query 1: This is the most common way to do multiple table update in Access. This may be a primary key column or a column with unique index, or columns with combined uniqueness (also known as composite unique index).

update Customer Sales_Retail as a inner join ( select x. Sales Date from Customer Sales as x inner join Customer Sales_Retail as y on x. Uniqueness prohibits duplicated values in the column(s).

Customer Sales is a linked table (the source table - data came from this table).

Customer Sales_Retail is a local table (target table - contains the data I wanted to update). Sales Date Query 3: Here is another way of doing the same thing as Query 2, but here in the sub-query it uses IN rather than INNER JOIN. Sales Date To fix the problem, I had to split my original update query into two queries.

To Add criteria, click on the Show/Hide Criteria button in the tool bar, select the Criteria Field and enter a Value.

If you have more than one criteria, type all criteria in the same Value row if they are AND condition.

It is possible to join additional tables from another source (must be under the same folder, same file type) by clicking on the Add Table button in the tool bar.Source table: Customer Sales (this is a linked table in Access) Target table: Customer Sales_Retail (this is an Access local table) What we want to do is to change Sales Date value in the Customer Sales_Retail table to new sales date stored in the linked table. It's less efficient than using inner join because join can take advantage of the index on the join column if it exists. The first one is a make-table query and the other one is a cross-table update query.The three queries below produce the same result, but none of them succeeded due to the Access error "Operation must use an updatable query". update Customer Sales_Retail as a inner join ( select Customer ID, Sales Date from Customer Sales where Customer ID in (select distinct Customer ID from Customer Sales_Retail) ) as b on a. Step #1: Make-Table query - create an intermediate (temporary but physical) local table To sum up, when we do multiple table updates in MS Access, first we need to make sure that the source table contains unique data in the joined column(s).I have a very simple SQL database sat on a SQL 2005 Server.I have at the moment as I am testing and learning 3 SQL Tables.
