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).It is a data structure consisting of a group of nodes which together represent a sequence.Under the simplest form, each node is composed of data and a reference (in other words, a link) to the next node in the sequence.The first table below lists the weekly Access Archon columns I wrote for Woody's Office Watch (many of them are now outdated and have been superseded by later articles in Access Watch).The Woody's Access Watch columns are listed in the second table, and the Access Watch columns in the third table.The goal of this table design tutorial is to provide information for beginning Microsoft Access programmers and future customers so that they will gain a basic understanding of relational databases.

In computer science, a linked list is a linear collection of data elements, called nodes, each pointing to the next node by means of a pointer.For multi-user databases proper design is important to reduce the probability of database corruption which is a main concern for Microsoft Access programs.These table design guidelines can be useful to most relational database programs.If after trying this example, you receive a "not defined" error on the "Dim db as Database" declaration, you will need to follow some additional instructions.Table Design examples for all aspects of Access databases can be found in this area of our website.Linked lists are among the simplest and most common data structures.
