Online SQL query builders let you create complex database queries without requiring knowledge of SQL syntax. Available is a whole line of options for combining SQL clauses like JOINs, GROUP BY with properties such as Sort Order, Sort Type, Criteria, aliases, Indexes, and Operators. Based on your choices, online SQL query builders will generate a comprehensive SQL statement which may be executed.


The functions of online SQL query builders are the following:


1. Connecting to a Database Server and Visually Creating Queries


To form SQL queries not using SQL statements, open the online SQL query builder window that has a connection to a Database Server. With column selection options allowing All Columns, Indexed Columns, Leading Indexed Columns or None, the GUI can be used in selecting tables or views.


With the many options provided by online SQL query builder, you can use any SQL property combination and write queries more powerfully and spontaneously. With Drag and Drop, you are able to add tables, columns, and views of an exact database or schema. With the table added to the diagram, the query can be seen in the SQL panel. Results of SQL queries can be seen in two modes - Grid and Pivot Grid.


2. Creating JOINS with Drag and Drop


Creating a JOIN in an SQL query involves dragging table columns table entity to table entity in the diagram panel. Changes made to the type of JOIN and its syntax instantly reflect on the SQL panel as they are made. You can change the JOIN type when you double-click on the Join line in the diagram and choose "Select All Rows."


3. GROUP BY and HAVING Clauses


To quickly insert GROUP BY Clause to a query, choose the columns and an aggregate function and into the Group By deck.


4. Executing Queries for Editing Tables


Execute your query to receive results in an editable grid ala Excel. To alter, insert, delete, clone and format data in the Table Data Editor, the Execute Edit comes in handy.


5. UNION Queries


The diagram pane can only show a single SELECT clause. In other words, working with a UNION query, the Query Builder will allow you to build an extra tabbed diagram to design a number of SELECT clauses to be UNION'ed together. The UNION keyword lets you include all results of multiple SELECT statements in one resulting table.


6. Sub Queries and Derived Tables



The Query Builder enables you to design an additional tabbed diagram to make a lot of SELECT clauses, which may also be used as Sub Queries in the column list, WHERE clause or as a Derived table to be part of a JOIN clause.
