Single quotes are used for string literals.In this tutorial you will learn how to create your own instance of MongoDB using Docker, and start using it configuring correctly Robo 3T. As with many database engines, field names may be surrounded with brackets or double quotes.

#Robo 3t tutorial code
For example, to read a zip code you would use "address.zip_code". This last one allows you to use standard OOP style dot-notation to read child fields. Accessing Embedded Fields Using Dotted Names.Testing If a Value Lies within a Range using BETWEEN.Testing If a Value Is a Member of a Set using IN.GROUP BY, ORDER BY and Aggregate Functions.Or in other words, right joins are not supported. While multiple joins are supported, each join can only reference tables to the left of it. This creates some limitations in the SQL implementation. These joins are expressed in MongoDB's native query language using the $lookup operator. Studio 3T adds new features fairly frequently and among the more recent updates is the ability to perform SQL-style inner and left joins against MongoDB data sets. As in other database engines, this will give you important information about the expected performance characteristics of the query. Besides being a useful training tool, this can save a lot of time that would otherwise be spent running lengthy integration tests.ĭevelopers using this feature should also take advantage of the "explain query" support. After verifying the query is working, you can switch to the "Query Code" tab to see what it would look like in JavaScript (node.JS), Java, Python, or C#. SQL to JavaScript (node.JS), Java, Python, and C# CodeĪ unique feature of Studio 3T is the ability to convert SQL to language specific code.
#Robo 3t tutorial manual
While this can be useful for manual data correction, normally one would set the tool into "read-only mode" when connecting to a production database to reduce the risk of making a mistake. Like many SQL-based tools, you can directly edit records in Studio 3T. It has the standard three-panel layout with the list of the collections on the left, an SQL editor on the top-right, and the results pane on the bottom-right. This user interface looks remarkably similar to what you would find in SQL Server Management Studio or PosgreSQL's pgAdmin. Studio 3T seeks to address this by providing a SQL-based user interface. With each NoSQL database needing its own specialized syntax, training costs can skyrocket. The main exception to this is the so-called NoSQL databases. With a vendor supplied tool and a basic understanding of SQL, users can query any type of data without extensive training in that particular product. The ability for users to directly query and explore data has long been a hallmark of professional databases.
#Robo 3t tutorial pro
Studio 3T is available in a range of commercial versions, and several new features like the SQL Query and Query Code generation features require the Studio 3T Pro version. Studio 3T, a cross-platform MongoDB GUI and IDE, has provides a SQL-based user interface for issuing queries against MongoDB.
