Oracle Database
Query Builder Tool

Oracle Query Builder is a flexible SQL query creation tool provided by dbForge Studio for Oracle. The Query Builder functionality allows you to visually build queries of any complexity, easily find and filter database objects, build relationships between objects, inspect formatted query results, and save queries without going into SQL detail.

With the Oracle Query Builder tool you can build SELECT statements with multiple tables, joins, conditions, and subqueries without manual code typing. Add your subqueries to any part of the main query and create a complex condition with expression builder. Besides, you will be able to:

  • Utilize robust visual Oracle query builder functionality
  • Combine a few queries into a sub-query via visual query editor
  • Take your Oracle database management to a whole new level
  • Easily make various types of JOINs between tables
  • Discover trends from heaps of data to see its whole scope
  • Reduce the time you spend on building complex queries

Building queries visually
in several clicks

You can create any query visually by simply clicking the button on the toolbar to open a query document in the Oracle Query builder tool. Query document contains the diagram and the tabbed editor.

Editing selected statements can be done both ways - visually with Query Builder for Oracle and using SQL editor.

When you switch from your SQL document view to Text view, all changes are applied to the query text in SQL Editor. After you change the code of your selected statement, you can return to view and inspect these changes in visual mode. The same is when using Oracle Query Builder dialog box - you can switch between the Query Builder for Oracle interface elements and SQL editor in the lower right part of the dialog.

Working with
complex subqueries

dbForge Studio for Oracle offers full support for subqueries in all SELECT statement clauses. With the query tool for Oracle databases, you can generate a sequence of queries of any complexity - each subquery can have its own subqueries.

When you create a subquery using Oracle Query Builder or open it for visual editing, a subquery tab of the query document appears. These tabs allow navigating subqueries easily. You can navigate to the upper-level query from the subquery with the Parent Query button on the Oracle Query Builder toolbar. You can also use the Document Outline window to navigate the complex queries.

Creating JOINs
Between Tables

Using the Query Builder tool, you can establish relationships between your tables by creating JOINs visually. Depending on the desired results, you can choose from 5 types of JOINs: inner join, left outer join, right outer join, natural join, and cross join. Additionally, you can easily set very complex conditions for any kind of JOIN in a matter of several clicks.

If you already have a table with a foreign key and place the referenced table on the diagram, the Oracle query tool will automatically perform a JOIN.
