Unable to call stored procedure within stored procedure - sql

Question

I have three stored procedures A, B, C
and definition of A is like
StoredProcedure A
As
Begin
--Some Stuff
Exec DBO.B [Derived Conitions]
Exec DBO.C [Derived Conitions]
END
but whenever I tried to execute the stored procedure A, at parsing time it give waring;
The module 'A' depends on the missing object 'B'. The module will still be created;
however, it cannot run successfully until the object exists.
The module 'A' depends on the missing object 'C'. The module will still be created;
however, it cannot run successfully until the object exists.
At execution time it throws exception
Could not find stored procedure 'dbo.B'.
Could not find stored procedure 'dbo.C'.
I found so many answers for calling a stored procedure with in stored procedure, but none of them worked for me.

You certainly can execute multiple procedures from within a single SP. You can even us the results from 1 SP as parameters in another.
In your specific case I suspect that there is a permissions / security or collation error which is stopping you from access the B and C stored procs.
Here is an example of SP chaining at work.
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[DerivedProcedures]
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Temporary table used to store results from SP1
DECLARE #Results_ForStoredProcedure1 TABLE
(
[SPID] INT,
[Status] NVARCHAR(50),
[Login] NVARCHAR(50),
[HostName] NVARCHAR(50),
[BlkBy] NVARCHAR(5),
[DBName] NVARCHAR(50),
[Commad] NVARCHAR(50),
[CPUTime] INT,
[DiskIO] INT,
[LastBatch] NVARCHAR(50),
[ProgramName] NVARCHAR(50),
[SPID2] INT,
[RequestId] INT
)
-- Execute SP1
INSERT INTO #Results_ForStoredProcedure1
EXEC sp_who2
-- Temporary table to store the results from SP2
DECLARE #Results_ForStoredProcedure2 TABLE
(
[DatabaseName] NVARCHAR(50),
[DatabaseSize] INT,
[Remarks] NVARCHAR(50)
)
-- Execute SP2
INSERT INTO #Results_ForStoredProcedure2
EXEC sp_databases
-- do something with both SP results
SELECT DISTINCT SP2.*
FROM #Results_ForStoredProcedure1 AS SP1
INNER JOIN #Results_ForStoredProcedure2 AS SP2 ON SP2.DatabaseName = SP1.DBName
WHERE SP1.DBName IS NOT NULL
END
GO
-- TEST
EXECUTE [dbo].[DerivedProcedures]

Perhaps, it sounds hilarious but I was getting the mentioned issue as I was using the wrong DB name (for example-Use 'XYZ'). Actually, in my case I was transferring a SP from one environment to another but after doing so I would not change the corresponding DB name .Due to which I was getting the error as the SPs which were involved were present in different DBs in the dissimilar environment.
In nutshell,please check the DB name which should be the very first line of your SP.
For example- Use 'XYZ'.
