project on query in ms access

IMPORTANT NOTESBefore you could take prints of this PRESENTATION make sure you update few details like your NAME, ROLL NUMBER, AND YOUR TEACHERS NAME etc.One more thing I have removed all the background images because in case you guys take B & W print-outs it would be horrible.. So its a recommendation take prints in this format and in your VIRTUAL PRESENTATION you guys can add up all the ANIMATIONS & OTHER STUFF to make it look good so that your faculty knows that you know it all

Last but not the least for any POPAT please dont blame me.For any other issues send me a PM..

RegardsVikas.(,)

ACKNOWLEDGEMENT I express my gratitude and heartily thanks to our respected faculty Mr. Jitender sir, Mr. Alok sir and Mr. Vinay sir for their guidance and constant support towards the preparation of this project, moreover without all the mentioned names this project would not have seen the light for the evening.

QUERY IN MICROSOFT OFFICE ACCESS

QUERY??IntroductionAs tables grow in size they can have hundreds of thousands of records, which makes it impossible for the user to pick out specific records from that table. Queries were designed to combat this problem. With a query you can apply a filter to the table's data, so that you only get the information that you want.The tricky part of queries is that you must understand how to construct one before you can actually use them. This lesson will guide you through the basics of making a couple very simple Access queries.Definition Queries are the primary mechanism for retrieving information from a database and consist of questions presented to the database in a predefined format.

In Simple WordsA query is a set of instructions that you can use for working with data. You run a query to perform these instructions. In addition to returning results which can be sorted, grouped, or filtered a query can also create, copy, delete, or change data.

Queries Object In MS Access we can use queries to extract information (data) from one (or more) tables (or from other queries). The information we retrieve can be limited by the definition of our query. In access queries are database objects that can be used to retrieve a subset of data. Unlike filters queries can be saved and used as a data source for other ms access objects such as reports, forms or data access pages.

TYPES OF QUERIESSelect Query.

Update Query.

Append Query.

Delete Query.

HOW TO USE QUERY?Choosing A Table To Query.Before we can create a query we have to navigate to the Query Tab in our Access database. Select Queries from the Objects Pane.

CURRENT DATABASE THAT WE HAVE

Although we could use the Wizard, we will guide through the process of creating an Access query with the "Design view". Creating a query by using Wizard gives us an option to run Automated and Pre-defined set of instructions to create and run a query.CREATING QUERY BY USING WIZARD

Continuing Query In Design ViewDouble-click Create Query in Design viewAdd the table.

3) Our Query window should now have the table added to it.Now we in the setup process for making a query. Every time we make a query we have to first choose which table(s) we want to select data from. Currently, our database only has 2 table, so we don't have a lot of choices here.The table(s) added will appear like the boxes encircled.

Inserting Field For Setting up Query.

The insertion of fields can be done by using drop-down box appears in fields and by dragging and dropping directly from the tables to query field.

1)SELECT QUERYThe select query is the simplest type of query and because of that, it is also the most commonly used one in Microsoft Access databases. It can be used to select and display data from either one table or a series of them depending on what is needed.In the end, it is the user-determined criteria that tells the database what the selection is to be based on. After the select query is called, it creates a "virtual" table where the data can be changed, but at no more than one record at a time.

Select query can be used to view subset of recordsRetrieve data form one (or more) tablesDisplay the results in a datasheetupdate the records from within the datasheetgroup records and do calculations (sum, average, counts, totals, etc).

By default Microsoft Office Access Always Opens Select Query So We Need Not Choose It Particularly. However Select Query can be chosen from Query Tab.

Firstly we need to insert (populate) and select all the fields on which Select Query needs to be run.

Then in Criteria we should choose the basis on which Select Query is to be performed.

In Case Select Query Needs To Be Run On 1 Table With 2 Different Filters On Different Fields Then The Option Of OR Can Be Used And Desired Result Can Be Obtained.

2) UPDATE QUERYUsing update query you can make global changes to a group of records in one or more tables. For example, you can raise grades by 10 percent for all Students (or a subset of students).An Update query is a query that makes updates to many records at the same time.

Keep In Mind About The Formula.While Applying The Formula To Any Field Following Things Should Be Followed.

1)Formula Should Be Put-in To Update-to.Table Name! (An Exclamation Sign Should Be Given After Table Name For Reference) i.e. Employee Salary Details Is Above Example.The Name Of Base Field For Updating i.e. Basic_PayThen The Calculative/Mathematical Formula i.e. *10/100{Where * Denotes Multiply & / Denotes Division}Formula Should Be Put In Without Any Spaces.

After clicking Update Query From Query Tab We Need To Click Run & On The Confirmation Dialogue Box Click Yes So That The Table Gets Updated Which Can Be Saved Then Accessed From The Table Manu.Result Window

3)APPEND QUERYAppend Query is used to add records/group of records from one or more tables at the end of an existing table. Append Queries are especially useful for adding old records to the end of a table.For example, suppose that we drop Students form one Class1and register them for Class2. We can append records into the Class2.

Since in Select Query we can only get the data we have Selective Approach.

An Update query is used for calculation & replacing function.

But if there are more than one database exists and we want to merge both of them then Append Query is used to join or merge the databases.

Existing Database We HaveNow We want to merge both of the above shown table into one.To execute this desire we will perform Append Query

How To Run Append Query1)Firstly, we must choose Query From The Database.Then, we need to choose the option Create Query In Design View. (Either WIZARD or DESIGN VIEW can be used).Add the table which we would like to append another tables data or table and insert required fields.Choose Append Query from the Query Tab.Append Windows which comes up next select the Table which needs to be appended or updated.

Click RunQuery Confirmation Box

4) DELETE QUERYA Microsoft Office Access Delete Query deletes records from a single database table or database tables. Of all of the different action queries available in Microsoft Access (Select Queries, Append Queries, Update Queries and Delete Queries) the delete query is one of the most dangerous. Unlike the others mentioned, the Microsoft Access delete query will remove records from your tables permanently and forever. As with the other types of action queries, the delete query will work with a group of records that meet a specified criteria that you apply. You can use the delete query to remove all records or only records that meet the defined criteria.In Simple Words: Delete Query allows us to delete a group of records that meet specific search criteria in bulk. The procedures for setting up a Delete Query depends on whether we are deleting records from a single table or from multiple tables that are involved in a one-to-many relationship

How To Run Delete QueryExisting Table With 10 Records

1)Firstly, we must choose Query From The Database.

Then, we need to choose the option Create Query In Design View. (Either WIZARD or DESIGN VIEW can be used).

Add the table in which any specific desired data needs to be deleted.

Table With Desired Fields Inserted To It For Running Delete Query

Criteria Has Been Set For Delete Query To Run

Delete Query Confirmation Dialogue Box.We need to click on yes so that Delete Query comes into picture and delete the desired records/data.

Result WindowFINAL OUTPUT. THE TABLE NO LONGER HAS RECORDS FOR FARISH AND HAS ONLY 9 RECORDS
