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.
OPENJSON() is a table-valued function that returns JSON in tabular format. That is, it converts your JSON into a tabular result set consisting of rows and columns. Therefore, it enables you to insert it into a table.
SQL Server has a table-valued function called OPENJSON() that creates a relational view of JSON data.
When you call it, you pass a JSON document as an argument, and OPENJSON() then parses it and returns the JSON document’s objects and properties in a tabular format – as rows and columns.
This article presents two ways to return a list of table-valued functions in a SQL Server database.
In SQL Server, it’s usually a good idea to schema bind your user-defined functions (UDFs).
Schema binding your UDF will ensure that the underlying tables can’t be changed in a way that would affect your function. Without schema binding, the underlying tables or other objects could be modified or even deleted. Doing this could break the function.
When creating a user-defined function in SQL Server, you have the option of encrypting it.
To create a user-defined function with T-SQL, you use the CREATE FUNCTION syntax. To encrypt it, you add the WITH ENCRYPTION argument.
You can also use the same argument to encrypt an existing function when using ALTER FUNCTION.
When you create a table-valued function (TVF) in SQL Server, you can either make it an inline table-valued function (ITVF) or a multi-statement table-valued function (MSTVF). There are differences between these function types, and they use a different syntax accordingly.
This article covers the difference between MSTVFs and ITVFs.
In SQL Server, the multi-statement table-valued function is one of two types of Transact-SQL table-valued functions (the other type being the inline table-valued function).
Table-valued functions (TVF) are a type of user-defined function that return their results as a table. They can therefore be queried just like a normal table.
In SQL Server, the inline table-valued function is one of two types of Transact-SQL table-valued functions (the other type being the multi-statement table-valued function).
Table-valued functions (TVF) are a type of user-defined function that return their results as a table. They can therefore be queried just like a normal table.
You can alter a table-valued function (TVF) in SQL Server using the ALTER FUNCTION T-SQL syntax.
You simply follow ALTER FUNCTION with the new definition. Basically it’s like using CREATE FUNCTION except you replace CREATE with ALTER.
You can create a table-valued function (TVF) in SQL Server using the CREATE FUNCTION T-SQL syntax.
The syntax is slightly different depending on whether you’re creating an inline table-valued function (ITVF) or a multi-statement table-valued function (MSTVF).
