Yesterday while I was writing script for SQL SERVER – 2005 – Find Unused Indexes of Current Database . I realized that I needed SELECT statement where I get the name of the current Database. It was very simple script.
SELECT DB_NAME() AS DataBaseName
It will give you the name the database you are running using while running the query.

1) I have 2 db one is parent db and another one is child db.
2) suppose while using child db i need parent table information normall we are using parent..tablename.
3) statically we declare @db=parent at that time we use exec() the query.
for ex:
declare @DB varchar(20)
set @db= parent
exec
(
‘select * from child inner join
(
SELECT distinct ia_grn_num FROM ‘+@DB+’..invtb_adjust where ia_stock_num = ”TYREI”
) b on ir_grn_num = b.ia_grn_num’
)
4) I want to use set @db= parent but i dont want to use exec() the query. Is it posible to sql server?
Hi Dave, similar question: I have multiple DBs with similar Schemas (for different levels of development). I need a way to dynamically specify which of these schemas is the one I want.
Kind of like a: “USE [Ask me for which DB and insert it here]” statement at the top of the script.
Any ideas?

MSSQL – How do you find which db the query is running.

i do i get dbname1, dbname2 in output column automatically.
in this case i cannot use db_name()
thank you sir,
i have one task..,
how can i get databases having same login,Password
Hello. I’m hoping for a solution to an issue I have.
There seems to be an explicit name set in a stored procedure, to a database that I had renamed for the sake of doing lab work.
The original name of the database was FOO1, and I restored it as FOO2. I’m using a tool in learning how to reverse engineer a database when I noticed that I have quite a few errors because of a reference in a Stored Procedure that references FOO1 explicitly.
The error I’m getting is:
Unable to resolve object ‘FOO1’.[myTable] in unknown ‘[MyServer].[FOO1]’ referenced by stored procedure ‘[MyServer].[FOO2].dbo.[myStoredProcedure]’
So I understand the error it’s looking for something in what was the original name of the database.
I found the line in the stored procedure that makes this reference:
FROM FOO1.dbo.Usertable p, ….
Is there a way (in a stored procedure) to automagically get database name, set it as a variable for example as, @DBNAME, so that I can change it to look like:
FROM @DBNAME.dbo.Usertable p …
Could someone please provide insight :)
Greatly appreciated.
thank u..
I have 3 databases in one server named A, B,C. One procedure sp_1 is in B. I will call that procedure from either A or C.According to calling database (i.e A or C) I have to set @Calling_Db_name which is in Procedure sp_1.
How I can do this.
Please help me..
How can you use the current database name to populate a field. The login default database in sql server query Cheers Nick
Can you please explain a bit more on your requirement Nick? DB_Name() would give you the value and it can be used with INSERT / UPDATE statement for you. So let me know.
How to search by database name within SQL server management studio because I have over 3,000 database attached to each instance

Good afternoon Pinal
May you help me telling me how to pass db_name() as default paramenter in a user defined function in sql server 2008, something like this:
CREATE FUNCTION [dbo].[test](@p_e1 AS [SYSNAME] = @@SERVERNAME, @p_e2 AS [SYSNAME] = DB_NAME())
RETURNS [BIT]
AS
BEGIN
IF @p_e2 = N’Some Data Base’
BEGIN
RETURN 1;
END
ELSE
BEGIN
RETURN 0;
END;
END
GO
Thanks a lot for your valuable help.
Thank you very much. Great.
Is there a way to find the database name or ID from within a stored procedure? DB_NAME() always returns the name of the database that the procedure is defined in. I want to know the name or ID of the database that the stored procedure was called from. Is this possible?
For example, If I have a procedure called MY_PROC, defined in MAIN_DB, that displays a database name,
USE DATABASE_A
GO
EXEC MAIN_DB.dbo.MY_PROC — Should Return ‘DATABASE_A’
USE DATABASE_B
GO
EXEC MAIN_DB.dbo.MY_PROC — Should Return ‘DATABASE_B’
Thank You,
Robbie
