This function returns the name of the stored procedure or trigger where an error occurs, if that error caused the CATCH block of a TRY...CATCH construct to execute.

SQL Server 2017 thru current version returns schema_name.stored_procedure_name
SQL Server 2016 returns stored_procedure_name

Transact-SQL syntax conventions

Syntax

ERROR_PROCEDURE ( )

Return Types

nvarchar(128)

Return Value

When called in a CATCH block, ERROR_PROCEDURE returns the name of the stored procedure or trigger in which the error originated.

ERROR_PROCEDURE returns NULL if the error did not occur within a stored procedure or trigger.

ERROR_PROCEDURE returns NULL when called outside the scope of a CATCH block.

Remarks

ERROR_PROCEDURE supports calls anywhere within the scope of a CATCH block.

ERROR_PROCEDURE returns the name of the stored procedure or trigger where an error occurs, regardless of how many times it runs, or where it runs, within the scope of the CATCH block. This contrasts with a function like @@ERROR, which only returns an error number in the statement immediately following the one that causes an error.

A. Using ERROR_PROCEDURE in a CATCH block

This example shows a stored procedure that generates a divide-by-zero error. ERROR_PROCEDURE returns the name of the stored procedure where the error occurred.

-- Verify that the stored procedure does not already exist.  
IF OBJECT_ID ( 'usp_ExampleProc', 'P' ) IS NOT NULL   
    DROP PROCEDURE usp_ExampleProc;  
GO  
  
-- Create a stored procedure that   
-- generates a divide-by-zero error.  
CREATE PROCEDURE usp_ExampleProc  
AS  
    SELECT 1/0;  
GO  
  
BEGIN TRY  
    -- Execute the stored procedure inside the TRY block.  
    EXECUTE usp_ExampleProc;  
END TRY  
BEGIN CATCH  
    SELECT ERROR_PROCEDURE() AS ErrorProcedure;  
END CATCH;  
GO

Here's the result set.

B. Using ERROR_PROCEDURE in a CATCH block with other error-handling tools

This example shows a stored procedure that generates a divide-by-zero error. Along with the name of the stored procedure where the error occurred, the stored procedure returns information about the error.

-- Verify that the stored procedure does not already exist.  
IF OBJECT_ID ( 'usp_ExampleProc', 'P' ) IS NOT NULL   
    DROP PROCEDURE usp_ExampleProc;  
GO  
  
-- Create a stored procedure that   
-- generates a divide-by-zero error.  
CREATE PROCEDURE usp_ExampleProc  
AS  
    SELECT 1/0;  
GO  
  
BEGIN TRY  
    -- Execute the stored procedure inside the TRY block.  
    EXECUTE usp_ExampleProc;  
END TRY  
BEGIN CATCH  
    SELECT   
        ERROR_NUMBER() AS ErrorNumber,  
        ERROR_SEVERITY() AS ErrorSeverity,  
        ERROR_STATE() AS ErrorState,  
        ERROR_PROCEDURE() AS ErrorProcedure,  
        ERROR_MESSAGE() AS ErrorMessage,  
        ERROR_LINE() AS ErrorLine;  
        END CATCH;  
GO

Here's the result set.
