Whenever you have to store JSON-encoded strings but you don’t need to manipulate or query the data too often. For scenario #7, the Altoros team had to write 347 lines for MongoDB query language, compared to 21 lines of N1QL. Transcript. The second OPENJSON function will parse JSON array and return string values as single column rowset that will be joined with the result of the first OPENJSON. Most basic operations are supported, but joins are not supported, nor sub-selects, group bys, or certain database functions. Amarnath Gupta . Example. As with ONDB, not all aspects of JPQL are supported. You can organize collections of your JSON documents in tables, establish relationships between them, combine strongly typed scalar columns stored in tables with flexible key/value pairs stored in JSON columns, and query both scalar and JSON values in one or more tables by using full Transact-SQL. If you are familiar with Amazon Web Service, DynamoDB, MongoDB, Couchbase databases, you should be familiar with the JSON documents. MongoDB has is own JSON based query by example language. Load, query, and analyze log data stored as JSON files with all the power of the Transact-SQL language. As for the data types BSON supports, all the datatypes commonly found in JSON and includes two additional datatypes (Binary Data and Date). JSON is also used for storing unstructured data in log files or NoSQL databases such as Microsoft Azure Cosmos DB. SQL Server provides a hybrid model for storing and processing both relational and JSON data by using standard Transact-SQL language. A database query is a request to access data from a database to manipulate it or retrieve it. Even with Mongodb querylanguage, you will find that it is based on the select-join-project construct, which is the foundation of relational algebra that is used in SQL. Write your MongoDB query as a JSON object. It does not support SQL (i.e. This enabled developers to build applications with the flexibility of a schemaless design model, Hardie said. ...

NoSQLBooster for MongoDB supports mongoose-like fluent query builder API that enables you to build up a query using chaining syntax, rather than specifying a JSON object. Run some queries that call the stored procedures and views that you created in steps 2 and 4. ", He said the disadvantage of using JSON and the documental model databases is that engineers need to design how to nest the data structure in objects and arrays from the start. To better understand, let’s go back to the advent of the first databases designed for the masses, which appeared around 1960. The next section shows some of the sample data used by this example. This can result in read and update operations being 4 or 5 times faster and updates to very large JSON documents being 20 to 30 times faster," Hardie claimed. SQL Server can also format query results in any format, such as OData JSON or GeoJSON. For a visual introduction to the built-in JSON support in SQL Server and Azure SQL Database, see the following video: Using JSON in SQL Server 2016 and Azure SQL Database, Building REST API with SQL Server using JSON functions, Validate, query, and change JSON data with built-in functions (SQL Server), Convert JSON Data to Rows and Columns with OPENJSON (SQL Server), Format Query Results as JSON with FOR JSON (SQL Server), Format query results as JSON with FOR JSON (SQL Server), Store JSON documents in SQL Server or SQL Database, Optimize JSON processing with in-memory OLTP, {"info":{"address":[{"town":"Belgrade"},{"town":"London"},{"town":"Madrid"}]}.
