Functions of Online SQL Query Builders

Online SQL query builders let you create complex database queries without requiring knowledge of SQL syntax. A whole range of visual options is available to let you combine SQL clauses like JOINs and GROUP BY with such properties as Criteria, Sort Order, Aliases, Indexes, Operators, and Sort Type. Depending on your choices, online SQL query builders will generate a whole SQL statement that may be executed.

The following are the functions of online SQL query builders:

1. Connecting to a Database Server and Visually Creating Queries

To form SQL queries not using SQL statements, open the online SQL query builders 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 multiple options in online SQL query builder, you can combine any of the SQL properties and make writing queries a more natural and powerful process. Drag and Drop lets you include tables, columns, and views of a particular schema or database. When the table has been added to the diagram, the query may now be viewed in the SQL panel. Results of SQL queries can be seen in two modes - Grid and Pivot Grid.

2. Making JOINS with Drag and Drop

A JOIN in a SQL query builder can be created by dragging table columns from one table entity to the next in the diagram panel. Changes made to the type of JOIN and its syntax instantly reflect on the SQL panel as they are made. Alter the JOIN type by double-clicking on the Join line in the diagram and choosing "Select All Rows."

Swiftly insert GROUP BY Clause to a query by picking the columns and an aggregate function from the list and to the Group By deck.

4. Executing Queries for Editing Tables

Execute your query to receive results in an editable grid ala Excel. The Execute Edit feature is very handy for making changes, cloning, deleting, and formatting data in Table Data Editor.

5. UNION Queries

Only a single SELECT clause can be shown in the diagram pane. 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. Results of all SELECT statements can be included in a single resulting table using The UNION keyword.

6. Sub Queries and Derived Tables

The 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.
