Need To Pass 'UserName' To SQL Select WHERE Clause In The Data Source
May 30, 2007
Hi.
I bet this is a 101 question, but i'd appreciate any help!
I am in the 'where...' section of the configure data source wizzard .
Column: I grab 'UserName'
Operator: I select '='
BUT how do I get the UserName (The user is signed into the app)
Is it from the Form? Profile? Session?
Ive tried profile.name.....
THANKS In advance....

VB ASP.NET 2.0
How do I get the Authenticated UserName passed to a Select Command of a data control ?
I'm not clear on how to get the logged in username from User.Identity.Name as a string or how to pass it to the Select Command of a control.
I've had some success with SelectParameters / ControlParameter's in the Master Control context, but otherwise I don't understand how to create a Parameter for use with the SQL.
I want to show the user data from a database, based on who is logged in .
Help, greatly appreciated.

I'm using the asp.net login controls and am storing the user data in the sql table that get's automaticaly built by visual studio. I display records based on who is logged in. Currently i use a Session parameter in my datasource for the user name and store the username in a session variable on the page load event, Session["UserName"]= User.Identity.Name.
Is there a way i can use a Profile parameter in my data source and skip setting session variable all together? I tried putting Name and UserName and User.Identity.Name in the Profile property but nothing seems to work. Thanks for any help.

We installed SQL7 over the weekend. Everything was working peachy through yesterday. This morning SQL server is requiring all of the queries to require references to the username in the from clause...
For example
"Select * from mytable" used to work fine. Not it requires "select * from username.mytable"
I'm logged in as the same username, which is the DB Owner as well. Any idea why this is happening all the sudden?
TIA

Does anyone have any ideas why this will not work?

I'm working on a query in which I need to get few nodes values from the XML data by using the value from SQL column (MessageContentType) in this query. I'm able to get the nodes value when i hard code the value in the query but the problem is MessageContentType will vary from some records in the table, due to that I'm not getting the corresponding node values. I have tried few ways to get this value dynamically but I'm missing something.
Sample Table Data
MessageContentType | BodySegment
xx:ADT_A03_26_GLO_DEF | <ns0:ADT_A03_26_GLO_DEF xmlns:ns0="http://microsoft.com/HealthCare/HL7/2X">.....
Current Query - HardCode Script
SELECT
ID,MsgContentType
BODYSEGMENT,
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /xx:ADT_A03_26_GLO_DEF[1]/colxx[1]/colxx[1]','varchar(300)') AS TimeSpan
FROM
s
When i tried the below line of script, I'm getting this error "[color=#FF0000]The argument 1 of the XMLdata type method "value" must be a string literal.[/color]"
Concat MsgContentType Column
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /'+MsgContentType+'[1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan
To overcome that error i used sql column but I'm getting this error [color=#FF0000]XQuery [S.bodysegment.value()]: Syntax error near '[', expected a "node test"[/color].
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /[sql:column("MsgContentType")][1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan
I tried this line of script, i didn't get any error by timespan is coming as null, I do hope this script not pointing the correct node to traverse the sibling node.
BODYSEGMENT.value('declare namespace xx="http://microsoft.com/HealthCare/HL7/2X"; /*[local-name()=sql:column("MsgContentType")][1]/EVN_EventType[1]/EVN_2_RecordedDateTime[1]','varchar(300)') AS TimeSpan

Hi,
I use a DataGrid to show the data, and I want it has a sorting and Paging function,
so I use dataset to collect the data from middle tier function and stored procedure.
I have code in aspx page like BindData(ViewState("SortExpr")).
In the stored procedure I pass SortExpr as parameter as following:
CREATE Procedure Ruying_AutoSearch10
(
@Make varchar(50),
@Model varchar(50) = NULL,
@Condition varchar(20) = NULL,
@Miles float,
@Zipcode varchar(5),
@SortExpr varchar(100)
)
AS
DECLARE @RowCount int
SELECT @RowCount = Count(*) FROM ZIPCodes WHERE ZIPCode = @Zipcode AND CityType = 'D'
if @RowCount > 0
BEGIN
SELECT
z.ZIPCode, z.City, z.StateCode, a.Make, a.Model, a.AutoPrice, a.AutoPrice2, a.AutoYear, a.Mileage, a.AdID, a.ImageURL, dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) As Distance
/*
The above functions requires the Distance Assistant.
*/
FROM
ZIPCodes z, RadiusAssistant(@ZIPCode,@Miles) r, AutoAd a
WHERE
z.Latitude <= r.MaxLat
AND z.Latitude >= r.MinLat
AND z.Longitude <= r.MaxLong

AND dbo.DistanceAssistant(z.Latitude,z.Longitude,r.Latitude,r.Longitude) <= @Miles
ORDER BY @SortExpr
END
ELSE
SELECT -1 As ZIPCode
--ZIP Code not found...
GO
but I got the error as "variables are only allowed when ordering by an expression referenceing
a column name". How I fix this error? Please help.

How to pass value for the “in� clause in the SQL server stored procedure? Let us consider the following code.
declare @Country varchar(200)
set @CountryIds='1,11'
select CountryName from COUNTRY where CountryId in (@CountryIds)
GO
In the above code, the lists of country ids are needed to feed from the front end. In the above example, we need to select countries for 1 and 11. So, how to pass this from front end and what will be the data type of the parameter. I am using front end as .Net. Please help in this regard. The stored procedure what I wrote was.
CREATE PROCEDURE [cmp].[Events_By_Country]
@CountryIds varchar(200)
AS
select CountryName from COUNTRY where CountryId in (@CountryIds)
GO

How does one pass into a Stored Procedure an array of numbers to be used in an IN clause? If I pass "1,2" in a VARCHAR, the stored procedure sees only the first number (1 in this case).
I'm using VB and ADO.NET, but I don't know how to set up the stored procedure for an array. Is there a parsing function to do this?
CREATE PROCEDURE TestInClause( @TeamList VARCHAR)ASSELECT Name FROM Teams WHERE TeamID IN (@TeamList); /* sees only 1st number */GO

I created a stored procedure like the following in the hope that I can pass mulitple company_id to the select statement:
CREATE PROC sp_test @in_company_code nvarchar(1024)
AS
select company_code, name, description
from member_company
where company_code in (@in_company_code)
However, I tried the following :
exec sp_test 'abc', 'rrd', 'bbc'
Procedure or function sp_test has too many arguments specified.
and SQLServer doesn't like it.
Did I specify this stored procedure correct?
If so, how can I can pass multiple values to the stored procedure then to the sql statement?
If not, is it possible to specify a stored procedure like this?
Thanks!

I'm writing some generalized stored procedures for use form managed code. The following stored proc works great:
CREATE PROCEDURE fnd_Send (
@Message VARCHAR(5000),
@Contract SYSNAME,
@MessageType SYSNAME,
@FromService SYSNAME,
@ToService VARCHAR(100),
@Encrypted Bit
)
AS
BEGIN
DECLARE @Handle UNIQUEIDENTIFIER;
BEGIN DIALOG CONVERSATION @Handle
FROM SERVICE @FromService
TO SERVICE @ToService
ON CONTRACT @Contract
WITH ENCRYPTION = OFF;
SEND ON CONVERSATION @Handle
MESSAGE TYPE @MessageType(@Message);
Notice the use of SYSNAME parameters €“ translating the parameter into an object name - allows it to work in the BEGIN DIALOG statement when an system object is needed. Works create and cues up generic messages.
The following will not compile:
CREATE PROCEDURE fnd_Receive (
@Queue SYSNAME,
@Message VARCHAR(5000) out,
@MessageType SYSNAME out
)
AS
BEGIN
DECLARE @Handle UNIQUEIDENTIFIER;
RECEIVE TOP (1)
@Handle = conversation_handle,
@MessageType = message_type_name,
@Message = message_body
FROM @Queue;
END
GO
It won€™t let me use the SYSNAME field @Queue in the FROM clause. I€™m getting an unfriendly:
Msg 102, Level 15, State 1, Procedure fnd_Receive, Line 15
Incorrect syntax near '@Queue'.
It looks like maybe I can€™t bind a variable in the FROM clause €“ perhaps like you cannot in a SELECT statement. I can fall back to dynamic SQL in the stored proc or in the managed code; I was hoping not to.
Can anyone shed any light on this? Also, are there any other techniques I'm missing to avoid falling back to a dynamic SQL statement.
Thank you in advance -

Dear All,
I have created a DTS Package in Integration Services 2005.
Within the DTS Package declared a variable named xxx and passed a value 1234.
In the control flow i dropped a Data flow task and in the Property Expression Editor of DataFlow Task i defined
Property = [DataReader Source].[sqlCommand]
Expression = Variable name.
Now in the DataFlow Task Canvas dropped DataReaderSource.
How can i pass variable value to the SQLCommand ="Select * from table where name = Variable value.

Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

Years ago, I remember while doing maintenance on a stored procedure seeing a 'Select x, y, z Where 'some value' = 1.
The function of this, I believe was to make the select work but not retrieve any actual values.
I am attempting to use this in an 'Insert Into Select values From' statement. This insert uses multiple selects via unions and I need a final dummy Select statement with no Where criteria.
What I am thinking may not even apply to what I need to do here.
If you recognize something even remotely near what I am trying to get across I would appreciate your sending me the code.
Another solution for me is just inserting one row with a final RecId = 6 and ' ' or 0 values for the other fields into a table
but I was hoping this would work.
Example:
Insert Into table
Select
1 as RecId,
' ' as field1,
field2
From test1
Where field2 = 'CA'
Union
Select
2 as RecId,
' ' as field1,
field2
From test1
Where field2 = 'NJ'
Union
/*Final Select */
Select
6 as RecId,
' ' as field1,
field2
From test1
Where 'some value' = 1'
Thanks much for your assistance!!!

2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)

In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

Far below (in section "original 3 steps"), you see the following:1. a temp table is created2. some data is inserted into this table3. some of the inserted data is removed based on a join with the sametable that the original select was made fromIn my opinion, there is no way that the join could produce more rowsthan were originally retrieved from viewD. Hence, we could get rid ofthe DELETE step by simply changing the query to be:INSERT INTO #details ( rec_id, orig_corr, bene_corr )SELECT rec_id, 0, 0FROM viewDWHERE SOURCE_SYS NOT IN ( 'G', 'K' )AND MONTH( VALUE_DATE_A8 ) = MONTH( @date )AND YEAR( VALUE_DATE_A8 ) = YEAR( @date )AND INMESS NOT LIKE '2__' ---- the added line===== original 3 steps (mentioned above) =====CREATE TABLE #details (rec_id UNIQUEIDENTIFIER PRIMARY KEY NOT NULL,orig VARCHAR(35) NULL,bene VARCHAR(35) NULL,orig_corr TINYINT NULL,bene_corr TINYINT NULL)INSERT INTO #details ( rec_id, orig_corr, bene_corr )SELECT rec_id, 0, 0FROM viewDWHERE SOURCE_SYS NOT IN ( 'G', 'K' )AND MONTH( VALUE_DATE_A8 ) = MONTH( @date )AND YEAR( VALUE_DATE_A8 ) = YEAR( @date )DELETE dFROM #details dJOIN viewD v ON ( d.rec_id = v.rec_id )WHERE INMESS LIKE '2__'

typeof(MiningModelColumn)));
mc.SourceColumnID = ms.Columns["Customer ID"].ID;
mc.Usage = "Key";
mm.Columns.Add(mc);
mm.Update();
Please exactly say, whatever I want
Thanks a lot for your answer
Please don€™t move this question because I don€™t know where I should write this.

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
Thanks in advance

Hi,
I've a custom database with created by Dynamics CRM setup. When i access this database using the user who installed it, It returns full data. But when i try to access the same tables using some other username e.g. [sa] / [any other user], it doesn't return me even a single record. Database instance is set to mix mode authentication, and i can connect using username [sa], but no data is available from 1 perticular database.
I've even given select rights to [public] on that specific database, but no results. Can anyone help me getting results using these usernames?
