T-SQL (SS2K8) :: Nested Stored Procedure - Multiple Results Of Record Sets Coming
Oct 1, 2014
I am calling stored procedure called GetCommonItemCount within another stored procedure called CheckBoxAvailability, the first stored procedure should return a count to second stored procedure and based on that some logic will be executed.
I have 2 problems in that
1. The result is not coming from first stored so the variable called @Cnt is always 0 although it should be 18
2. At the end i need to see in the output the result from second stored procedure only while now i am seeing multiple results of record sets coming.
I have attached the scripts also, the line i described in step1 is

I have a report based on our product names that consists of two parts.Both insert data into a temporary table.1. A single grouped set of results based on all products2. Multiple tables based on individual product names.I am getting data by calling the same stored procedure multipletimes... for the single set of data I use "product like '%'"To get the data for individual products, I am using a cursor to parsethe product list.It's working great except that I have no idea how to identify theresults short of including a column with the product name. While thatis fine, I'm wondering if there is something that is like a header ortitle that I could insert prior to generating the data that would looka little tighter.Thanks in advance-DanielleJoin Bytes!

I have a stored procedure like the following. This returns 2 result sets, however i only want it to return 2nd (SELECT SomeField FROM SomeTable). How is this done? Note - it is not possible to change 'SomeSPThatReturnsAnIntAndAResultSet '
CREATE PROCEDURE [dbo].[SomeSP]
@SomeParam int
AS
BEGIN
SET NOCOUNT ON;
declare @SomeScalar int
exec @SomeScalar = SomeSPThatReturnsAnIntAndAResultSet @SomeParam
if @SomeScalar = 0
BEGIN
SELECT SomeField FROM SomeTable
END
END

Hi all,
I want to know how to handle multiple result sets return from Stored Procedure? I know one way is to insert the result sets into the table, but the limitation is the result sets must have the same data structure. If the result sets have different data structure, how can I handle it.
Thanks,

Firstly may I say that the sproc I am having problems with and the service that calls it is inherited technical debt from an unsupervised contractor. We are not able to go through a rewriting process at the moment so need to live with this if possible.
Background
We have a service written in c# that is processing packages of xml that contain up to 100 elements of goods consignment data. In amongst that element is an identifier for each consignment. This is nvarchar(22) in our table. I have not observed any IDs that are different in length in the XML element.
The service picks up these packages from MSMQ, extracts the data using XPATH and passes the ID into the SPROC in question. This searches for the ID in one of our tables and returns a bool to the service indicating whether it was found or not. If found then we add a new row to another table. If not found then it ignores and continues processing.
Observations
The service seems to be dealing with a top end of around 10 messages a minute... so a max of about 1000 calls to the SPROC per minute. Multi-threading has been used to process these packages but as I am assured, sprocs are threadsafe. It is completing the calls without issue but intermittently it will return FALSE. For these IDs I am observing that they exist on the table mostly (there are the odd exceptions where they are legitimately missing). e.g Yesterday I was watching the logs and on seeing a message saying that an ID had not been found I checked the database and could see that the ID had been entered a day earlier according to an Entered Timestamp.
So the Sproc...
USE [xxxxxxxxxx]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
[Code]....
So on occasions (about 0.33% of the time) it is failing to get a bit 1 setting in @bFound after the SELECT TOP(1).
The only suggestions I can make have been...
change @pIdentifier nvarchar(25) to nvarchar(22)
Trim any potential blanks from either side of both parts of the identifier comparison
Change the SELECT TOP(1) to an EXISTS
The only other thought is the two way parameter direction in the C# for the result OUTPUT. Not sure why he did it that way or what the purpose is.
I have been unable to replicate this using a test app and our test databases. Has observed selects failing to find even though the data is there, like this before?

Is it possible to return the results of a stored procedure into either a CTE or temp table?
In other words, is it possible to do this:
with someCTE as (
exec someStoredProc
)
or this:
exec someStoredProc into #tempTable
???

I have a few questions about the following t-sql 2008 r2 sql code listed below that is calling a stored procedure:
DECLARE@return_value int,
@endYear SMALLINT = 2014,
@CustomerID INT = '9999',
@Schedules CHAR(1) = N'C'
EXEC [dbo].[sproom] @endYear
,@CustomerID
,@Schedules
The sql listed above does execute the stored procedure called [dbo].[sproom] successfully and returns all the data all the rows from the stored procedure multiple times. However can you tell me the following:
1. How can I have the stored procedure return distinct rows?
2. I want the stored procedure to return selected columns. I tried using the OUTPUT parameter for some of the columns, but I got the error message, "Procedure or function spHomeroom has too many arguments specified.".
when I change the sql above to:
DECLARE @return_value int,
@endYear SMALLINT = 2014,
@CustomerID INT = '9999',
@Schedules CHAR(1) = N'C',
@CustName varchar(50)
EXEC [dbo].[sproom] @endYear
,@CustomerID
,@Schedules
,@CustName
That is when I get the error message.
A solution might be to change the stored procedure, but I would prefer not to since this is a generic stored procedure that I believe a lot of t-sqls and stored procedures will use.

I have a stored procedure on a SQL Server 2008 database. The stored procedure is very simple, just a SELECT statement. When I run it, it returns 422 rows. However, when I run the SELECT statement from the stored procedure, it returns 467 rows. I've tried this by running both the stored procedure and the SELECT statement in the same SSMS window at the same time, and the behavior is the same. The stored procedure is:
USE [REMS]
GO
/****** Object: StoredProcedure [mobile].[GetAllMobileDeviceUsers] Script Date: 12/04/2014 */
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[Code] ....
When I do this in the same SSMS window:
exec mobile.GetAllMobileDeviceUsers
SELECT
ee.EmployeeID,
EmployeeName = LastName + ', ' + FirstName
FROM EmployeeInvData ee
--UNION
[Code] ....
I get two result sets. The first is 422 rows; the second is 467 rows. Why?

If I have multiple selects statements in one stored procedure. How do I access the different results in a report in Reporting Services? Where the first select is the detail lines of my report and the second select is just a field for a my header? Or am I going about this wrong with putting it all the results I want into one stored procedure for one report?
Example stored procedure:
ALTER PROCEDURE [dbo].[proc_DepositsByOfficer]
As
SELECT MASTER_DSC.APP
, MASTER_DSC.BRANCH
, qlkpOfficer.strName
, MASTER_DSC.DSC_OFFICER_49
, qlkpBranchName.strDescrS

Dear All,This is a query surrounding a problem I encounteredyesterday.In SQL Server, it is possible to write a procedure thathas one or more select statements in it.The results from these select statements will all beindividually returned to SQL Query Analyser where theycan be viewed in "grid" views. Also, these individualresults sets can be consumed by eg ADO.NET by steppingthrough each results set in turn and processing therespective results.My question is, can you do the same in a SQL Serverprocedure? ie:Create Procedure Proc1ASbeginselect Col1, COl2from Table1select Col1, Col2, Col3from Table2endCreate Procedure Proc2ASbeginexec Proc1endCan both/either of the results sets from Proc1 beconsumed by the calling procedure Proc2?I can see that you could design the procedures up-front to do almost anything without consuming theresult sets in this way, but if the proceduresreturning the results sets are already built andin use in other places (for instance in client code),can they be re-used on server-side SQL procedures?Thanks in anticipation!Paul.

I have a MSSQL2000 table called partspec.dbo.locationIn this table are 2 smallint columns: Tester (numbered 1-40) and Line (numbered with various integers)I am trying to create a stored procedure to read the tester number like so:Select Tester from partspec.dbo.location where Line = 2which will return up to 5 tester number results, lets say 11, 12, 24, 29 ,34My question is how do I store these tester numbers into 5 variables so that I may use them later in the sp ? So it would go something like this:CREATE PROCEDURE Table_Line
(@Tester1 integer,@Tester2 integer,@Tester3 integer,@Tester4 integer,@Tester5 integer)ASSELECT Tester FROM partspec.dbo.location where Line = 2Now this is where I'm confused on how to get 1 value into 1 variable and so on for all 5 values returned. This is what I would like to happen:
@Tester1 = 11@Tester2 = 12@Tester3 = 24@Tester4 = 29@Tester5 = 34GOThank you for any and all assistance.

We are facing an issue while executing a stored procedure which uses a table of current database with INNER JOIN a table of another database in same instance.
Per our requirement, we are inserting select statement output in table variable. Then applying business logic and finally showing the data from table variable.
This scenario is working exactly fine in Dev environment. But when we deployed the code in quality environment. Stored procedure does not returning OUTPUT/ (No column names) from table variable.
During initial investigation, we found that collation of these two databases are different but we added DATABASE_DEFAULT collation in the JOIN.

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

Consider a situation where a stored procedure taking a varbinary(max) (BLOB) input parameter then calls a nested stored procedure and passes along that varbinary(max) as an input parameter to the nested stored procedure.
Is a copy of the BLOB provided to the nested stored procedure (passed by value) OR is the BLOB passed by reference.
My interest is in understanding the potential memory hit when handling large BLOBs in this environment.
For example, if the BLOB is 200MB, will SQL server need to allocate memory for a new copy each time it's passed to another stored procedure?
Looks like table type parameters are passed by reference, but I haven't been able to find any info on BLOBS in this context.

Hi,
Here is my sample table creation and insertion script.
I want represent as a summary-result using just one record.
How can I ?
Please note the below red color text.
create table policy
(
id int not null,
name nvarchar(50) not null,
constraint pk_policy primary key(id)
);
create table localhost
(
policy_id int not null,
id int not null,
ip_begin binary(4) not null,
ip_end binary(4) not null,
prefix tinyint not null default 0,
constraint pk_localhost primary key(policy_id,id)
);
create table remotehost
(
policy_id int not null,
id int not null,
ip_begin binary(4) not null,
ip_end binary(4) not null,
prefix tinyint not null default 0,
constraint pk_remotehost primary key(policy_id,id)
);
create table rate
(
policy_id int not null,
inbound int not null,
outbound int not null,
constraint pk_rate primary key(policy_id)
);
-------------
insert into policy values(0,N'policy0');
insert into localhost values(0,0,0xC0A80101,0xC0A80101,24);
insert into localhost values(0,1,0xC0A80A01,0xC0A80B01,0);
insert into remotehost values(0,0,0xACA80101,0xACA80101,0);
insert into remotehost values(0,1,0xACA80A01,0xACA80B01,0);
insert into remotehost values(0,2,0xACA80C01,0xACA80C01,24);
insert into rate values(0,1000,2000);
-------------
select * from policy;
select * from localhost;
select * from remotehost;
select * from rate;
-- result of policy table
0 policy0
-- result of localhost table
0 0 0xC0A80101 0xC0A80101 24
0 1 0xC0A80A01 0xC0A80B01 0
-- result of remotehost table
0 0 0xACA80101 0xACA80101 0
0 2 0xACA80C01 0xACA80C01 24
-- result of rate table
0 1000 2000
------------------------------------------------------
desired result set
id name localhost remotehost rate
-- ---------- ---------------------------------------------------------------- ------------------------------------------- -----------------
0 policy0 (192.168.1.1/24),(192.168.10.1~192.168.11.1) (172.168.1.1),(172.168.12.1/24) 0,1000,2000
descriptin of desired result set :
0. key value is id column and is referenced by each policy_id column.
1. id and name column is the same as policy table's.
2. localhost and remotehost columns are intigration of ip_begin,ip_end,prefix.
3. ip_begin and ip_end should be converted dotted presention from numeric format.
4. if prefix greater than 0, it should be displayed using '/'.
5. if ip_begin and ip_end are equal, show just one ip.
6. if the two ips are different from each other, they separated by '~'.
7. rate field is packed divided by ','.

Better method to detect records with one or more 0's, other than hard coding all of the potential values. For example, I need to detect account duplicates where the duplicate contains multiple/all 0's in the "MasterAccount" column:
DECLARE @Account TABLE(AccountNo varchar(3), MasterAccount varchar(10) )
INSERT INTO @Account
SELECT 'ABC','0000000ABC' UNION
SELECT 'DEF','0000000DEF' UNION
SELECT 'ABC','0000000000' UNION ---- unwanted duplicate
SELECT 'DEF','00000' UNION ---- unwanted duplicate

Is there a better method than this?

1 1 0 0
1 0 0 1
2 0 1 0
3 0 1 0
Now I want the records having flag2=1 only.. I.e ID=3 has flag2=1 where as ID = 1 and 2 has flag1 and flag3 =1 along with flag2=1. I don't want ID=1 and 2.
I can't make ID unique or primary. I tried with case when statements but it I am somehow missing the basic logic.

If you write a stored procedure to "SELECT MAX" from a table and the answer is null since the table is empty, how is the null answer returned to the program from the stored procedure? Do you actually get the letters "NULL" or do you just get a space? How should you define your variable in your program?
Thanks in advance!

VS.NET 2005 automatically deploys a CLR stored procedure when you start a project with debugging. However, if the CLR stored procedure attempts to access external resources you will get a message stating:
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I've isolated this to being because the CLR stored procedure does not have the EXTERNAL_ACCESS permission set.
Is there a security attribute that can be used to decorate the CLR stored procedure code so that VS.NET 2005 will register the CLR stored procedure with the correct permission set?

Greetings
I have a SQL Server stored procedure that performs several queries and therefore returns several "result sets" at any one time.
Wiring it up via ADO.NET I populate a DataSet with a number of items in the Tables collection - which is great - and I can give each item a name for identification purposes once the DataSet is populated.
But I'd like to know if there is some way I can set the names of each result set *within the text of the stored procedure*, i.e. before the DataSet gets populated.
Any help greatly appreciated.

I have a novice question. How does one suppress result sets returned from a stored procedure?
I have created a procedure which makes use of multiple stored procedures . The purpose of this procedure (lets call it procA), is to count the rows returned from other procedures. The €œOther€? procedures will return rows having an unknown number of columns. I would like to limit any changes which may be needed to be made to the €œOther€? procs.
Once procA has collected all of the information (@@rowcount) from the inner procedures, then it will return a result set having several columns €“ mainly the subProcedure name and number of rows returned.
The purpose of procA is to query several subsystems and identify which ones need attention.
Cursor While Loop
exec @ProcName @ObjectName,@userID,@syncDate
set @recs = @@rowcount;
My c# program calls the sp as follows:
cmd = DataUtility.GetSQLCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "FetchAdminData";
cmd.Parameters.AddWithValue("@userID", userAlias);
cmd.Parameters.AddWithValue("@adminDate",userDate);
reader = cmd.ExecuteReader();
I do not wish to iterate over each resultSet when I am only interested in the last one. Any suggestions?

Hi there everyone. I have a stored procedure called “PagingTable� that I use for performing searches and specifying how many results to show per ‘page’ and which page I want to see. This allows me to do my paging on the server-side (the database tier) and only the results that actually get shown on the webpage fly across from my database server to my web server. The code might look something like this:
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
The problem is the stored procedure actually returns two result sets. The first result set contains information regarding the total number of results founds, the number of pages and the current page. The second result set contains the data to be shown (the columns specified). In ‘classic’ ASP I did this like this.
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
I am trying to do this now in ASP.NET 2.0 using the datasource control and the repeater control. Any idea how I can accomplish two things:
A) Bind the repeater control to the second resultset
B) Build a “pager� of some sort using the values from the first resultset

I am currently reading through Itzik Ben-Gan's "Microsoft SQL Server 2012 High-Performance T-SQL using Windows Functions." In attempt to test the SUM OVER() function in SQL 2008 because that's what I've got. I do not currently have sample data (trying to generate it has become a major PITA), but I have some pseudocode.
My current code (actual production code) pulls a bunch of ITD (inception to date) contracts then calculates a certain dollar amount based on monthly changes. Not all contracts have values during a given month, so here's what I cobbled together a few months ago. (Per our finance team, these numbers ARE accurate).
WITH MonthlyVals AS
(SELECT ContractID, SUM(Col1 - (Col2 + Col3 + Col4 + Col5)) AS MyTotal
FROM MyTable
WHERE MyDate >= @ThisMonthStartDate AND MyDate <= @ThisMonthEndDate
AND StatementType IN (8,4,2)
[code]....
To test the totals, I also added a COMPUTE SUM(MyTotal) to the end of each query. (Yes, I know COMPUTE is deprecated. Just wanted a quick check.). The difference between the two bits of code was over 68k, with the SUM OVER() code coming up with a total higher than the CTE code. I know CTE code is correct for a fact. It went through extensive testing before getting put in Production. Is it the way I joined the table for the SUM OVER()? Or is it the use of PARITION BY?

I'm baffled by the results of the following query:
__________________________________________________ ______
select events.[report number], [microfilm number], [crash date]
into lowspeed
from events inner join vehicles
on events.[report number] = vehicles.[report number]
where [dummy record] = 'N'
and [estimated mph] between 1 and 10
and ([1st harmful event] = 01
or [2nd harmful event] = 01)
and [type of vehicle] in
('01','02','03','04','05','06','07','08','10','11' ,'12')
and [crash injury severity] = 5
select events.[report number], [microfilm number], [crash date]
into notlowspeed
from events inner join vehicles
on events.[report number] = vehicles.[report number]
where [dummy record] = 'N'
and [estimated mph] > 10
and ([1st harmful event] = 01
or [2nd harmful event] = 01)
and [type of vehicle] in
('01','02','03','04','05','06','07','08','10','11' ,'12')
and [crash injury severity] = 5
select distinct [report number], [microfilm number], [crash date]
into truelowspeed
from lowspeed where [report number] not in (select [report number] from
notlowspeed)
select [report number]
into pedtable
from pedestrians
select [report number],[microfilm number], [crash date]
as [Lowspeed Fatal Crashes - 1994]
from truelowspeed
where [report number] not in (select [report number] from pedtable)
drop table pedtable
drop table truelowspeed
drop table lowspeed
drop table notlowspeed
_______________________________________________
Let me explain what I'm trying to do.
In the first temp table "lowspeed," I'm trying to lump all crashes where a vehicle was doing between 1 and 10 mph.
In "notlowspeed," I'm setting up a table of crashes in which at least one vehicle was going over 10 mph.
By the third gyration, I'm trying to generate "truelowspeed;" which I thought would contain only crashes in which all of the criterion in the first two queries were satisfied and all of the vehicles involved in the crashes were doing between 1 and 10 mph (NO vehicles exceeding the 1 to 10 mph parameter).
The "pedtable" maneuver is simply to pull out any of these crashes in which a pedestrian was involved.
What I'm getting is a lot of crashes in which I have dummy records, several crashes in which one of the vehicles was going over 10 mph, and types of vehicles involved in the crash that should have been excluded by the criterion I specified.
Thoroughly stumped. Would be most grateful for any kind insight/advice.

Hi
I have data in the following format
Custid Age Product
101 25 ProdA
101 25 ProdB
102 25 ProdA
103 50 ProdC
104 55 ProdA
105 50 ProdC
when I am using Clustering algorithm with 2 clusters and trying to perdict the product column the results are coming as below
Custid Age Product PerdictProd
101 25 ProdA ProdA
101 25 ProdB ProdA
102 25 ProdA ProdA
103 50 ProdC ProdC
104 55 ProdA ProdC
105 50 ProdC ProdC
Why so pl let me know where I am going wrong and is the data is not proper
Thanks
