Message

The schema name for a procedure or function is not specified.

Description

It is recommended to explicitly specify the schema when referencing a stored procedure or user-defined function.

Additional information

Explicitly stating the schema name helps prevent potential conflicts with objects in different schemas and enhances code readability. Additionally, specifying the schema can improve query performance by reducing the need for the database engine to resolve object references.

Noncompliant code example

SELECT * FROM DemoFunction()
DEClARE @result NVARCHAR(50)
EXEC @result = DemoProcedure

Compliant solution

SELECT * FROM dbo.DemoFunction()
DEClARE @result NVARCHAR(50)
EXEC @result = dbo.DemoProcedure
