StudCode, StudAddress įOR JSON AUTO CLAUSE Using dot “.” symbol with FOR JSON AUTO clause in the column aliases, does not affect in the generated JSON. SELECT StudId, StudName, StudCode, StudAddress FROM dbo.StudentInfoįOR JSON AUTO, ROOT( 'StudentInformation')įOR JSON PATH CLAUSE using dot “.” symbol with FOR JSON PATH clause in the column aliases, you can name the each object in the resulting JSON array. SELECT StudId, StudName, StudCode, StudAddress FROM dbo.StudentInfoįOR JSON PATH, ROOT( 'StudentInformation')įollowing statement uses the ROOT option with For JSON AUTO clause and creates a studentInformation JSON wrapper object around the JSON ouptut. For JSON PATH with ROOT Optionįollowing statement uses the ROOT option with For JSON PATH clause and creates a studentInformation JSON wrapper object around the JSON output. Using the ROOT option in the FOR JSON clause can be generated a wrapper object around the generated JSON output. SELECT StudId, StudName, StudCode, StudAddress FROM dbo.StudentInfo Using FOR JSON AUTO clause to generate JSON from table StudentInfo. You can provide specific columns as well. In select statement it is not mandatory to pass all table column’s name. SELECT StudId, StudName, StudCode, StudAddress FROM dbo.StudentInfoĪs you can see, It converts table output in Json format. Lets generate JSON from table using FOR JSON PATH clauseįollowing statement uses FOR JSON Path clause and generates JSON from table StudentInfo. Use FOR JSON PATH or add a FROM clause with a table name.” SELECT 'Microsoft SQL Server 2016' as DatabaseName,Īs you can see, It gives an error syaing “FOR JSON AUTO requires at least one table for generating JSON objects. Lets try to generate JSON without table, just gives hard-coded values. It requires at least one table to generate JSON when using FOR JSON AUTO clause. Using FOR JSON AUTO clause, you can not generate JSON without table. SELECT 'Microsoft SQL Server 2016' as DatabaseName, Using FOR JSON PATH clause you can generate JSON, in case if you do not have any table and passing hard-coded values as shown below. Lets understand the use of FOR JSON PATH and FOR JSON AUTO clause FOR JSON PATH Clause ( 'Rozer Hanery', 'D78JKHI', 'Condominum 3A, 3rd floor') GO INSERT INTO dbo.StudentInfo (StudName, StudCode, StudAddress) Lets look at an example using FOR JSON clause in SQL Server.įirst we create a sample table named as studentInfo and Insert some sample records in table. FOR JSON AUTO is used to format the JSON output automatically based on the structure of the SELECT statement. JSON QUERY SQL SERVER FULLFOR JSON PATH gives the full control over the format of the JSON output also can create wrapper objects and nest complex properties.Using FOR JSON clause, you can specify the structure of the JSON output explicitly with the help of PATH and AUTO as given below. It was introduced in SQL Server 2016 version. In this example, we use SELECT * INTO to create a new table and insert the contents of the JSON document into it.SQL Server FOR JSON Clause is used to format query result to JSON format or export data from SQL Server as JSON format. Therefore, it enables you to insert it into a table. That is, it converts your JSON into a tabular result set consisting of rows and columns. OPENJSON() is a table-valued function that returns JSON in tabular format. If you have a JSON document that you need to insert into a table in a SQL Server database, the OPENJSON() function could be just what you need.
