  • Whats best SQL datatype for storing JSON string?
    ISJSON (Transact-SQL) tests whether a string contains valid JSON JSON_VALUE (Transact-SQL) extracts a scalar value from a JSON string JSON_QUERY (Transact-SQL) extracts an object or an array from a JSON string JSON_MODIFY (Transact-SQL) changes a value in a JSON string Please refer this SQL Server documentation about JSON data in SQL Server
  • SQL Server json truncated (even when using NVARCHAR(max) )
    SQL divides the JSON result into chunks 2k in size (at least my SQL 2016 installation does), one chunk in the first column of each row in the result set To get the entire result, your client code has to loop through the result set and concatenate the first column of each record
  • Get names of keys from JSON in SQL Server - Stack Overflow

  • sql - Convert select query results into Json - Stack Overflow
    JSON AUTO would make quick work of this in but JSON support is available only in SQL Server 2016 and later, including Azure SQL Database For a T-SQL solution in SQL 2014 and earlier, you'll need to build the JSON string yourself
  • convert query output into json format in sql server
    The closest you get with pure T-SQL-JSON-support will be this: DECLARE @tbl TABLE(ApplicationID INT, Roles INT); INSERT INTO @tbl VALUES (1,1) ,(1,5) ,(3,5); SELECT t ApplicationID ,Roles Roles AS Roles FROM @tbl t INNER JOIN @tbl Roles ON Roles ApplicationID=t ApplicationID GROUP BY t ApplicationID,Roles Roles FOR JSON AUTO;
