I've created a trigger which task is to store information about the trigger-events. For example: "New employee added to the table on date 2014-10-13.
I've created a table - Audit - which stores all the information (from the trigger).
CREATE TABLE [dbo].[Audit](
[id] [int] IDENTITY(1,1) NOT NULL,
[tableName] [nvarchar](255) NOT NULL,
[auditData] [nvarchar](max) NULL,
[userName] [nvarchar](255) NOT NULL,
PRIMARY KEY (id))
However, the trigger I've created looks like this:
CREATE TRIGGER [dbo].[tr_Actor_ForInsert_Audit]
ON [dbo].[Actor]
FOR INSERT
AS
BEGIN
DECLARE @userName NVARCHAR(255)
DECLARE @tableName NVARCHAR(255) = 'Actor'
DECLARE @name VARCHAR(255)
DECLARE @birthdate DATE
SELECT @userName = SYSTEM_USER
SELECT @name = name FROM inserted
SELECT @birthdate = birthdate FROM inserted
INSERT INTO Audit VALUES (@tableName, 'New ' + LOWER(@tableName) + ' with Name = ' + @name +
' and Birthdate = ' + CONVERT(NVARCHAR,@birthdate) + ' was added at ' + CONVERT(NVARCHAR,GETDATE()), @userName)
END;
As you can see, the variable userName is initialized to SYSTEM_USER. but the variable tableName is intitialized to a hard-coded value .
Question: Is there any possible way to somehow generically initialized the variable tableName to the tableName the same way I did for userName?
For example, if something like this existed:
@tableName = SYSTEM_TABLE_WHERE_TRIGGER(TRIGGERNAME)_EXIST

Solution:
@tablename = OBJECT_NAME(parent_object_id)
FROM sys.objects
WHERE sys.objects.name = OBJECT_NAME(@@PROCID)**
