EQB is useful if you are learning SQL. Just build the queries you can imagine and see what they look like in SQL.
Moreover, the changes in the query being built are instantly reflected in the SQL box, so you can track any minor changes. This will allow you to get a more deep understanding of the way things work.
It allows you to build SQL queries to any database without need to deal with SQL syntax. It takes just a few clicks to add conditions and build the query. Using our user-friendly interface even quite complex SQL queries can be built in virtually human language.
Finding the necessary information from your database files requires the use of a powerful SQL query builder. Such a tool will allow you, for example, to quickly get important information such as the details on your most valuable customers. You can use a query builder to get the important information that you need quickly. To do this, you need to have the ability to build SQL queries to your database. Easy Query Builder is one of the better value and more user-friendly tools for doing exactly that. It provides you with the ultimate tool for extracting the necessary data from your database in minimal time with maximum reliability.
To extract data from a database, there are various options, but none of them are nearly as effective or as easy as having a dedicated SQL query builder like Easy Query Builder. Other options include spending countless hours learning the SQL language in order to make a new query. Doing it manually in this way not only takes time, but you will also need all of the specialist knowledge at your disposal which does not come cheaply if you need to hire extra staff to do the job. There are also other SQL query builder solutions which provide a basic GUI or command-line interface, but many of these are still extremely hard to use and/or do not provide the range of features that your company requires.
Having a full understanding of SQL code and syntax is hardly practical if you don’t already and to build SQL statements yourself, you will need to have an extensive knowledge in this area so that you can type in commands, table and field names and more. You will need to know exactly how your data is stored in the database. While a basic SQL query builder will provide users with an easier solution, it is also not ideal, since, in many cases, you will still need to have a degree of expertise in the inner workings of the database. The best way to do this is surely to use an SQL query builder which allows you to build queries in your own, natural language, rather than learning complex SQL routines.
Easy Query Builder is an SQL query builder designed to do exactly that. It makes the handling of otherwise extremely complex and technical queries much easier to handle. For example, you can select understandable attributes such as “Order Date” or “Customer Name.” Such operations can be easily carried out with just a few clicks of the mouse. The user interface is simple, but it still provides the highest degree of functionality that you expect from a powerful and versatile solution.
Easy Query Builder supports the majority of different database types such as MS SQL Server, MySQL, Oracle and MS Access amongst others. Results can also be exported to Excel spreadsheets for easier viewing and sharing.
The very best thing of all about Easy Query Builder is that it is freeware – it costs absolutely nothing at all!

The Query Builder allows you to define a subset of a table using a SQL-like WHEREclause and to display the result in the main window. The query result can then besaved as a new vector layer.
Query¶
Open the Query Builder by opening the Layer Properties and going to the General menu.Under Feature subset, click on the [Query Builder] button to open the Query builder.For example, if you have a regions layer with a TYPE_2 field, you couldselect only regions that are borough in the Provider specific filter expressionbox of the Query Builder. Figure_attributes_2 shows an example of the Query Builderpopulated with the regions.shp layer from the QGIS sample data.The Fields, Values and Operators sections help you to construct the SQL-likequery.
Figure Attributes 2:
The Fields list contains all attribute columns of the attribute table to besearched. To add an attribute column to the SQL WHERE clause field, double clickits name in the Fields list. Generally, you can use the various fields, values andoperators to construct the query, or you can just type it into the SQL box.
The Values list lists the values of an attribute table. To list all possiblevalues of an attribute, select the attribute in the Fields list and clickthe [all] button. To list the first 25 unique values of an attribute column,select the attribute column in the Fields list and click the[Sample] button. To add a value to the SQL WHERE clause field, doubleclick its name in the Values list.
The Operators section contains all usable operators. To add an operatorto the SQL WHERE clause field, click the appropriate button. Relationaloperators ( = , > , ...), string comparison operator (LIKE), and logicaloperators (AND, OR, ...) are available.
The [Test] button shows a message box with the number of featuressatisfying the current query, which is useful in the process of queryconstruction. The [Clear] button clears the text in the SQL WHEREclause text field. The [OK] button closes the window and selectsthe features satisfying the query. The [Cancel] button closes thewindow without changing the current selection.
QGIS treats the resulting subset acts as if it where the entire layer.For example if you applied the filter above for ‘Borough’, you can notdisplay, query, save or edit Anchorage, because that is a ‘Municipality’and therefore not part of the subset.

The only exception is that unless your layer is part of a database, using a subset will prevent you from editing the layer.
