Passing the array to the SQL Server storage procedure can enhance the database operation, but finding the most effective way may be challenging. This article discusses various methods and considers the database version.

SQL Server 2016 and higher versions:

Use the boundary list of string_split ():

This function divides the boundary string (such as '1,2,3') into a table.

Clear input definition Simplified maintenance can be

Compared with other methods, the performance has improved

Other precautions:

• The string split using OpenJSON () allows orderly split.
• UDT provides flexibility and can be reused in multiple storage procedures.

By understanding the available methods and its advantages, developers can choose the most effective way to pass the array to the SQL Server storage procedure according to their specific application needs.
