Hi I'am practically new in C#, so I want to ask you guys some question.
Let say I have this query:
"Select EmployeeID, EmpName from PI_Employee"
How can I retrieve the result from EmployeeID column and EmpName column and put it into collections of array, so I can call the array and use it again in another function. Can I possibly do that in C# ? if so, how ? please help me guys, I'm on the edge of nervous wreck in here so I could use a little help, any kinds of help. Thanks.

Filling a DataTable from SqlQuery : If SqlQuery returns some null values problem ocurrs with DataTable. Is it possible using DataTable with some null values in it? Thanks
How can I read a query result set (which are of type VARCHAR) into an array? i.e the result set comprises of just one column and 5 rows and i want to save these into an array to easily extract each row whenever i want to. Hope I have conveyed my idea clearly.
I€™ve inherited a project from one of the guys on our team who will be out sick for a while. He developed two for marshaling data between System.Drawing.Image and System.Byte(). He€™s storing the byte array data in a database image field.
I€™ve retrieved the byte array data from his database image fields and have successfully converted them to images using his ConvertByteArrayToImage method below. I have also converted and image to a byte array with his ConvertImageToByteArray method below and succfully stored the data in a database image field. However, when I retrieve the byte array data that I stored in the database the last line in his ConvertByteArrayToImage method throws an exception (Parameter is not valid). I€™ve not been able to find a working copy of his code that€™s storing the byte array data. Does anyone see anything I€™m overlooking?
Imports System.Drawing Imports System.IO
Public Sub InsertImage(ByVal pFilename As String)
Try
Dim lImage As Image Dim lBA() As Byte Dim lSQL As String Dim lQuery As Alcon.SQLServer.Database.clsQuery Dim lParameters As New Alcon.SQLServer.Database.clsParameters
lImage = Image.FromFile(pFilename)
ConvertImageToByteArray(lImage, lBA)
' Initialization lQuery = New Alcon.SQLServer.Database.clsQuery(mConnection)
I am between the "newbie" and "intermediate" stages of writing SQL code and I am wondering if there is a way to capture multiple results into one field so I can basically create a "set" for a unique identifier. Here is few result samples I receive from this code I am using now. ReqNo ProcID 7102005 1409 7102005 1796 7139003 1411 7139003 6097 7261030 1409 7261030 1796 7268303 3998 7268303 4000
I would like to create a single row for each "ReqNo" and have a field that will an array of the "ProcID" results I receive. In other words, for the first "ReqNo" 7102005, can I create a field that will combine the 1409, 1796 into one field? I am trying to capture an array of integers used for that "ReqNo" so I can use that as a unique identifier in a join for another table.
So, ideally my result would be: ReqNo ProcSet 7102005 1409, 1796 7139003 1411, 6097 7261030 1409, 1796 7268303 3998, 4000
Is this possible?
declare @startdate smalldatetime, @enddate smalldatetime , @month int, @year int
Is it possible to retrieve a particular row from a result set? For eg if my query returns 5 rows and i want to just retrieve the 3rd row from the result....is it possible? If yes...can someone tell me the syntax for it....would appreciate the gr8 help...
select PaySlipDate,EmpID, case ADCode when 'GPF' then ADAmount else 0 end GPF, case ADCode when 'GPF.ADV' then ADAmount else 0 end 'GPF.ADV' from EmpSalaryRecord
It is showing multiple records of each employee for each date. First a record with GPF and GPF.ADV both zero and then records with values. I want a single record for each date and employee.
I have two tables that have no relation. However, both have a column which has a field of nvarchar(50) that I want to retrieve together in one operation and bind to a DropDownList in a sorted fashion. So, what I'm trying to achieve is this: 1. SELECT name FROM table1 2. SELECT name FROM table2 3. Join the two results together and order them alphabetically 4. Return the result set I'm not sure how to do this or even if it's possible. Ideally I'm hoping it can be done in a stored proc.
Is there anyone who was able to successfully retrieve a full result set? I'm really having troubles getting the result after executing my query. Its really even hard to get sample codes over the net.
We have a sort of complex user structure in the sense that depending on the type of user the data resides in different tables. Therefor I needed a stored procedure that finds out what table to look for a certain column in. Below is such a stored procedure and it works like it should but my problem is that I don't know how to retrieve the result (which should be a string so can't use RETURN).
I've tried using an OUTPUT variable but since I just run EXEC (@statement) in the end I can't really set an output variable the common way (as in EXEC @outputVariable = PMC_User_GetUserValue(arg1, arg2..)) or can I?
I have also tried to use SELECT to catch the result somehow but no luck and Google didn't help either so now I'm hoping for one of you... Notice that you don't have to bother about much of the code except for the end of it where I want it to return somehow or figure out a way to call this stored procedure and retrieve the result.
Thanks in advance ripern

Information: I'm using SQL server 2012
create table datatable (id int, name varchar(100), email varchar(10), phone varchar(10), cellphone varchar(10), none varchar(10) ); insert into datatable values
I have a stored procedure that has a paramter that accepts a string of values. At the user interface, I use a StringBuilder to concatenate the values (2,4,34,35,etc.) I would send these value to the stored procedure. The problem is that the stored procedure doesn't allow it to be query with the parameter because the Fieldname, "Officer_UID" is an integer data type, which can't be query against parameter string type. What would I need to do to convert it to an Integer array? @OfficerIDs as varchar(200) Select Officer_UID From Officers Where Officer_UID in (@OfficerIDs) Thanks
Could you pls let me know that when we use the parameters how the sql server ıs able to keep all the datas on the strıng type?and also how ıt can be provıde that securıty on system(how ıt ıgnore to do sql ınjectıon...).

I'm trying to pass in a parameter value from an array in a loop that is used in a sql query and the results are populated to an xml file. The trouble is that I'm only getting the colums values in the outputted xml file. So I feel that the paramter is not being read.
So can anyone help as I'm really stuck on this one. The code is as follows :
public void DisplayUserInfo() {
ArrayList UserIdArrayList = IdentifyUserID(); foreach(string ShowUserIDString in UserIdArrayList) { try { SqlConnection SqlConn = new SqlConnection(DBConnString); SqlConn.Open(); Console.WriteLine("Connected to DB"); SqlDataAdapter SqlAD = new SqlDataAdapter(); SqlAD.SelectCommand = new SqlCommand("Select * from UserSystemSpecs where UserName ='+ShowUserIDString.ToString()+'",SqlConn); DataSet ds = new DataSet(); SqlAD.Fill(ds); ds.WriteXml(".\ResultsXML.xml", XmlWriteMode.WriteSchema); }
catch (Exception ex) { throw new Exception ("Error Connecting to DB. " + ex.Message); } //SqlConn.Close();
I have a this SP that inserts values into a table with results from a query, but at the same time I want to insert some default values.But thats NOT working the way I hoped for, actually sqlserver 2005 dont let me create this SP at all."Incorrect syntax near the keyword 'DEFAULT'."Can someone please tell me how I can achieve this? create procedure %PROC% ( @Ordre_ID int ) asbeginIF NOT EXISTS(SELECT Ordre_ID FROM tbl_Ordre WHERE Ordre_ID = @Ordre_ID AND Ordrestatus IN ('2', '3', '4'))BEGIN return 0;ENDIF EXISTS(SELECT Ordre_ID FROM tbl_Faktura WHERE Ordre_ID = @Ordre_ID)BEGIN return 0; ENDBEGIN TRANSACTIONINSERT INTO tbl_Faktura( Ordre_ID ,PostNummer ,KID ,Fakturastatus ,Kontonummer ,Forfallsdato ,Belop ,BekreftetBetaltDato ,Faktura_GUID ,Adresse ,PostBoks ,Fornavn ,Etternavn ) (SELECT O.Ordre_ID ,K.PostNummer ,DEFAULT ,DEFAULT ,SI.Kontonummer ,(getdate()+14) ,v_OTS.TOTALBELOP ,DEFAULT ,DEFAULT ,K.Adresse ,K.PostBoks ,K.Fornavn ,K.Etternavn FROM tbl_Ordre AS O INNER JOIN tbl_Kunde AS K ON O.Kunde_ID = K.Kunde_ID INNER JOIN v_OrdreTotalSum AS v_OTS ON O.Ordre_ID = v_OTS.Ordre_ID ,tbl_StatiskeInnstillinger AS SI WHERE O.Ordre_ID = @Ordre_ID ) UPDATE tbl_Ordre SET Ordrestatus = '6' WHERE Ordre_ID = @Ordre_ID COMMIT end go
I need to send the result of a procedure to an update statement.Basically updating the column of one table with the result of aquery in a stored procedure. It only returns one value, if it didnt Icould see why it would not work, but it only returns a count.Lets say I have a sproc like so:create proc sp_countclients@datecreated datetimeasset nocount onselect count(clientid) as countfrom clientstablewhere datecreated > @datecreatedThen, I want to update another table with that value:Declare @dc datetimeset @dc = '2003-09-30'update anothertableset ClientCount = (exec sp_countclients @dc) -- this line errorswhere id_ = @@identityOR, I could try this, but still gives me error:declare @c intset @c = exec sp_countclients @dcWhat should I do?Thanks in advance!Greg
I have an Execute SQL Task that executes "select count(*) as Row_Count from xyztable" from an Oracle Server. I'm trying to assign the result to a variable. However when I try to execute I get an error: [Execute SQL Task] Error: An error occurred while assigning a value to variable "RowCount": "Unsupported data type on result set binding Row_Count.".
Which data type should I use for the variable, RowCount? I've tried Int16, Int32, Int64.
---------------------------------------------------------------------- I executed it in my SQL Server Management Studio Express and I got: Commands completed successfully. I do not know where the result is and how to get the result viewed. Please help and advise.
HI, I ran a select * from customers where state ='va', this is the result...
(29 row(s) affected) The following file has been saved successfully: C:outputcustomers.rpt 10826 bytes

As the topic suggests I need the end results to show a list of shows and their dates ordered by date DESC. Tables I have are structured as follows:
SHOWS showID showTitle
SHOWACCESS showID remoteID
VIDEOS videoDate showID
SQL is as follows:
SELECT shows.showID AS showID, shows.showTitle AS showTitle, (SELECT MAX(videos.videoFilmDate) AS vidDate FROM videos WHERE videos.showID = shows.showID) FROM shows, showAccess WHERE shows.showID = showAccess.showID AND showAccess.remoteID=21 ORDER BY vidDate DESC;
I had it ordering by showTitle and it worked fine, but I need it to order by vidDate. Can anyone shed some light on where I am going wrong?
I am trying to code a WHERE xxxx IN ('aaa','bbb','ccc') requirement but it the return values for the IN keyword changes according to another column, thus the need for a CASE function.
WHERE GROUP.GROUP_ID = 2 AND DEPT.DEPT_ID = 'D' AND WORK_TYPE_ID IN ( CASE DEPT_ID WHEN 'D' THEN 'A','B','C' <---- ERROR WHEN 'F' THEN 'C','D ELSE 'A','B','C','D' END )
I kept on getting errors, like
Msg 156, Level 15, State 1, Line 44Incorrect syntax near the keyword 'WHERE'. which leads me to assume that the CASE ... WHEN ... THEN statement does not allow mutiple values for result expression. Is there a way to get the SQL above to work or code the same logic in a different manner in just one simple SQL, and not a procedure or T-SQL script.
I'm using a subquery to return a delivery charge line as a column in the result set. I want to see this delivery charge only on the first line of the results for each contract. Code and results are below.
declare @start smalldatetime declare @end smalldatetime set @start = '2015-03-22 00:00' -- this should be a Sunday set @end = '2015-03-28 23:59' -- this should be the following Saturday
In this example, I only want to see the delivery charge of 125.00 for the first line of contract HU004377. For simplicity I have only shown the lines for 1 contract here, but there would normally be many different contracts with varying numbers of lines, and I only want to see the delivery charge once for each contract.
