MICROSOFT ACCESS QUERIES AND HOW IMPORTANT THEY ARE IN YOUR DATABASE

The heart of any MS Access database system resides with the queries and I’m often asked to give new users a quick overview of this powerful application – here’s an example…

A Microsoft Access Database is a desktop application which stores large amounts of data and is able to recognize relationships between those data. It consists of data and tools that enable users to manipulate that data.

One of these tools are the queries. Microsoft Access Queries are used specifically to organize data on the Access database.

A database can hold multiple tables. Each of the tables can have hundreds of thousands of records. How the user extracts a specific section of the table or tables is by using the queries.

Displaying data in simple or complex ways is the typical function of a query. One simple way is by getting the names of all the customers in a table. But you can modify your query to include only a list of customers residing in London sorted by last name, and this is a more complex search.

Microsoft Access Queries and How Important They Are in Your Database

The main types of queries in Microsoft Access are select, action, parameter and aggregate.  How Many Types Do You Know And Use In Your Access Database?

Select Query

The select query is the simplest among them. It is used to retrieve data from tables. The data that will be displayed is dependent on the criteria of the user.

Action Query

Not only can a query be used in retrieving data, it is also used in deleting or updating records as well as creating tables and inserting data into tables. The type of query that does these is called the action query.

There are four kinds of action queries and they are as follows:

Append Query – gets the results of a query and add them to an existing table.

Delete Query – deletes the records in a table according to the set results of a query.

Make Table Query – creates a table based on the query set results.

Update Query – updates one or more fields in a table.

Parameter Query

A parameter query is a modified select query. It is either a value or a condition. This type of query functions along with other types of queries to get specific results that a user may want to retrieve. It basically refines the search by instructing the other query exactly what you want it to do.  An example of a parameter query is a specific date (3/30/2015) or a date in between start (3/1/2015) and end date (3/30/2015).

Aggregate Query

Like parameter query, aggregate query also works with other types of query. It chiefly generates an aggregated result from the selected groups. Some examples are Sum, Avg, Min, Max, Group By, Count, Where, First, and Last.

Obtaining data from a table consisting of a large amount of records without having to probe the table is the main importance of queries.

Microsoft Access Training: Building Access Label Reports

Continuing with the Microsoft Access training series, building Access label reports is pretty straight forward (especially with the built-in wizard tool). As a snapshot and quick peek into my Access database eBook, here’s some more information to help establish your options. This type of report can be used for printing label address information to fit a pre-defined or custom defined label sheet (normally an adhesive or plain paper sheet). It can be based on a Table, Query or another external data …

Action Queries - Archive data

"Who is going to take responsibility of your Access database?

The author may not be the end-user, the developer may not be the analyst. There are multiple roles when planning, designing, building and implementing a system not forgetting the running and maintenance of the Access database application.

Assign one person, and in his/her absence a second, to back up the data and store it off site on a regular basis without overwriting the last back up.  

How often you back up is determined by how much data are you willing to re-enter and how much time might have gone by until the loss is detected.

There are several ways to back and restore data from the standard back-up and restore of the whole database to individual tables using either the crude copy and paste action to the more sophisticated ACTION queries (namely Append, Delete, Make-Table and Update).

Action queries can wrapped up into calling macros or VBA procedures to automate this important task.

AutoCorrect names can be buggy and drain your database

Some of the Microsoft Access features were introduced to help improve functionality and automation. However, some of Access features became a hinderance rather than a benefit and one I want to quickly mention here is the 'AutoCorrect' option in the Access Options interface. This feature was introduced with Microsoft Access 2000. It tries to help users who rename a table field, so that queries, forms and reports automatically recognise the new field name. Microsoft has addressed some of the problems with this feature, but is it still buggy, incomplete, and casue a strain on performance and should be avoided. It is better to therefore turn the feature off and depending which version of Access you use can be accessed via the 'Options' command. For Access 2000/2002/2003 it can be found via Tools, options, General tab. In Access 2007 it can be found via the 'Office' button, Access Options, Current Database tab. Finally in Access 2010 i(and later versions) t can be found in File tab, Options, Current Database. Final point here is that you must remember to do this every time you create a new database, preferably before creating any other objects.

Join the tables - matching data types

Joining tables together to create that all powerful relational database; you need to follow a set of rules but keeping the same name field between the 'parent' and 'child' table will help to keep to the standards and conventions that other users will be able to understand and maintain when reporting on your data. What's also important is to ensure that the data types do match between fields but please be clear that if the 'Parent' field is set to an 'AutoNumber' (as a unique auto ID) that you must choose the 'Number' data type (for the many side) to the 'Child' table and that both field sizes are set to 'Long Integer'. All other data types and field sizes where applicable are like for like.
