Microsoft Access is software for organizing information in a relational database, which is a type of database whose structure is built based on the relationship between one data and other data stored in tables. Microsoft Access is the 11th version released by Microsoft since the presence of Microsoft Access 1. The ability of this software to manage databases has been recognized by many parties.

In a database containing hundreds or even millions of records, finding the data you need is not an easy job. A query is an important feature that can save you effort not only to search data in one or several tables at once but also to edit data and perform calculations.

A query is an object in an Access database and can be stored for repeated use. These characteristics make queries very helpful for handling data in a database.

Macros can execute a number of commands to execute one or more actions at once in response to an event. For example, you can create a macro that will automatically run by Microsoft Access every time you open a database. Although macros are not as powerful as VBA Visual Basic For Applications , Microsoft recommends prioritizing macros if the database you are creating will be used by many people. The reason is to maintain data security.

Data can be added directly to the database via tables, but this method is not efficient for tables that have too many fields and records. By creating a form that functions as a front-end database, data can be added to the database more easily.

In general, the form consists of several columns that are equipped with descriptions that explain what data must be entered and a number of buttons that can be clicked to execute certain commands or actions, such as the Print button to print a report.

Within the Create tab, there are a number of form creation features. Forms can be created in one click based on an existing table or created from scratch. To select which fields appear in the form, there is a Form Wizard available to do so. In addition to the Form Wizard, there are many other wizards to make it easier for you to complete work in Microsoft Access such as the Simple Query Wizard to create queries, the Lookup Wizard to create relationships between tables, the Report Wizard to create specific reports, and the Import Wizard to retrieve data.

Create and run an update query – Inside this course:

 

The next step can be a little bit tricky—you need to tell Access which fields to update and how to update them. Access lets you know how many records will be affected and that the changes can’t be undone by the Undo command.

They are extremely powerful and eliminate a lot of manual updates and unnecessary coding. They are also much easier to maintain and debug than module code. When confronted with the limitations of what you can do with SQL Syntax, you can supplement Access update queries with your own functions letting Access take care of updating the records, while you focus on the calculations.

Video: Use update queries to change data in Access

 
 

Modified 1 year, 4 months ago. Viewed 70 times. Any pointers are appreciated Thanks. Improve this question. June7 Your question is too broad and there is no code for analysis. Thanks — user Users can create tables, queries, forms and reports, and connect them together with macros.

Advanced users can use VBA to write rich solutions with advanced data manipulation and user control. Access also has report creation features that can work with any data source that Access can access. The original concept of Access was for end users to be able to access data from any source. It also has the ability to link to data in its existing location and use it for viewing, querying, editing, and reporting. This allows the existing data to change while ensuring that Access uses the latest data.

It can perform heterogeneous joins between data sets stored across different platforms. Access is often used by people downloading data from enterprise level databases for manipulation, analysis, and reporting locally. This makes it very convenient to distribute the entire application to another user, who can run it in disconnected environments.

One of the benefits of Access from a programmer’s perspective is its relative compatibility with SQL structured query language —queries can be viewed graphically or edited as SQL statements, and SQL statements can be used directly in Macros and VBA Modules to manipulate Access tables.

Users can mix and use both VBA and “Macros” for programming forms and logic and offers object-oriented possibilities. VBA can also be included in queries. Microsoft Access offers parameterized queries. These queries and Access tables can be referenced from other programs like VB6 and. Microsoft Access is a file server -based database. Unlike client—server relational database management systems RDBMS , Microsoft Access does not implement database triggers , stored procedures , or transaction logging.

Access includes table-level triggers and stored procedures built into the ACE data engine. Thus a Client-server database system is not a requirement for using stored procedures or table triggers with Access Tables, queries, forms, reports and macros can now be developed specifically for web based applications in Access Integration with Microsoft SharePoint is also highly improved. The edition of Microsoft Access introduced a mostly flat design and the ability to install apps from the Office Store, but it did not introduce new features.

The theme was partially updated again for , but no dark theme was created for Access. NET web forms can query a Microsoft Access database, retrieve records and display them on the browser. SharePoint Server via Access Services allows for Access databases to be published to SharePoint, thus enabling multiple users to interact with the database application from any standards-compliant Web browser.

Access Web databases published to SharePoint Server can use standard objects such as tables, queries, forms, macros, and reports. Access Services stores those objects in SharePoint. Access offers the ability to publish Access web solutions on SharePoint The macro language is enhanced to support more sophisticated programming logic and database level automation.

Microsoft Access can also import or link directly to data stored in other applications and databases. Microsoft offers free runtime versions of Microsoft Access which allow users to run an Access desktop application without needing to purchase or install a retail version of Microsoft Access.

This actually allows Access developers to create databases that can be freely distributed to an unlimited number of end-users. These runtime versions of Access and later can be downloaded for free from Microsoft. The runtime version allows users to view, edit and delete data, along with running queries, forms, reports, macros and VBA module code.

The runtime version does not allow users to change the design of Microsoft Access tables, queries, forms, reports, macros or module code. The runtime versions are similar to their corresponding full version of Access and usually compatible with earlier versions; for example Access Runtime allows a user to run an Access application made with the version as well as through Due to deprecated features in Access , its runtime version is also unable to support those older features.

Access stores all database tables, queries, forms, reports, macros, and modules in the Access Jet database as a single file. For query development, Access offers a “Query Designer”, a graphical user interface that allows users to build queries without knowledge of structured query language. In the Query Designer, users can “show” the datasources of the query which can be tables or queries and select the fields they want returned by clicking and dragging them into the grid. One can set up joins by clicking and dragging fields in tables to fields in other tables.

Access allows users to view and manipulate the SQL code if desired. Any Access table, including linked tables from different data sources, can be used in a query. Access also supports the creation of “pass-through queries”. This enables users to interact with data stored outside the Access program without using linked tables or Jet. When developing reports in “Design View” additions or changes to controls cause any linked queries to execute in the background and the designer is forced to wait for records to be returned before being able to make another change.

This feature cannot be turned off. Non-programmers can use the macro feature to automate simple tasks through a series of drop-down selections. Macros allow users to easily chain commands together such as running queries, importing or exporting data, opening and closing forms, previewing and printing reports, etc. Macros support basic logic IF-conditions and the ability to call other macros. Macros can also contain sub-macros which are similar to subroutines. In Access , enhanced macros included error-handling and support for temporary variables.

Access also introduced embedded macros that are essentially properties of an object’s event. You cannot use an update query to add new records to a database, or to delete records from a database. To add new records to a database you use an append query, and to delete whole records from a database you use a delete query. Using an update query. Update data from one table to another.

Stop Disabled Mode from blocking a query. Like the Find and Replace dialog box, an update query lets you specify which value is being replaced, and what the new value is. Calculated fields The values in calculated fields do not permanently reside in tables. They only exist in your computer’s temporary memory after Access calculates them.

Because calculated fields do not have a permanent storage location, you cannot update them. Fields from a totals query or a crosstab query The values in these types of query are calculated, and therefore cannot be updated by an update query. AutoNumber fields By design, the values in AutoNumber fields change only when you add a record to a table.

Fields in unique-values queries and unique-records queries The values in such queries are summarized. Some of the values represent a single record, and others represent more than one record. The update operation is not possible because it is not possible to determine what records were excluded as duplicates, and therefore not possible to update all the necessary records.

This restriction applies whether you use an update query or try to update data manually by entering values in a form or a datasheet. Fields in a union query You cannot update data from fields in a union query because each record that appears in two or more data sources only appears once in the union query result.

Because some duplicate records are removed from the results, Access cannot update all the necessary records. Fields that are primary keys In some cases, such as if the primary key field is used in a table relationship, you cannot update the field by using a query unless you first set the relationship to automatically cascade updates.

Note: When you cascade updates, Access automatically updates foreign key values when you change a primary key value in a parent table. As a best practice when creating an update query, first create a select query that identifies the records that you want to update, and then convert that query to an update query that you can run to update the records. Tip: Back up your database before you run an update query. You cannot undo the results of an update query, and making a backup helps make sure that you can reverse your changes if you change your mind.

Click the File Tab, and then click Save As. In the Save Backup As dialog box, specify a name and location for the backup copy, and then click Save. To revert to a backup, close and rename the original file so that the backup copy can use the name of the original version. Assign the name of the original version to the backup copy, and then open the renamed backup copy in Access. Step 1: Create a select query to identify the records to update.

Step 2: Update the records. On the Create tab, in the Queries group, click Query Design. Select the table or tables that contain the records that you want to update, click Add , and then click Close. The table or tables appear as one or more windows in the query designer, and the windows list all the fields in each table. This figure shows the query designer with a typical table. Double-click the fields that you want to update in the table windows.

Update Query Examples. Update Query Fails to Run. This can be due to several reasons: The database file is set to ReadOnly. None of the data can be modified. Change this at the Windows level. If the database is on a CD, copy it to your hard disk. If you’re using Access workgroup security, you may not have rights to edit the data.

In this case, login as the administrator or with a user name and password that gives you the appropriate rights. If the tables is linked, you may not have rights to modify the data on the backend data source.

Assuming you can edit your table, your query may fail and display this error message when you run it: Operation must use an updatable query Error Operation Failed If so, check out our paper on Error Operation must use an updatable query: Dealing with Non-Updateable Queries and the Use of Temporary Tables in Microsoft Access which discusses some of the issues and workarounds.
