Concatenate Strings After Assigning Text In Place Of Bit Strings
Feb 19, 2007I have a whole bunch of bit fields in an SQL data base, which makes it a little messy to report on.
I thought a nice idea would be to assigne a text string/null value to each bit field and concatenate all of them into a result.
This is the basic logic goes soemthing like this:
select case new_accountant = 1 then 'acct/' end +
case new_advisor = 1 then 'adv/' end +
case new_attorney = 1 then 'atty/' end as String
from new_database
The output would be
Null, acct/, adv/, atty, acct/adv/, acct/atty/... acct/adv/atty/
So far, nothing I have tried has worked.
Any ideas?
Manipulating Datetime
Dec 16, 1998Hi ppl
How do I subtract, say an integer from a datetime value. I tried to use the Convert function but wont work.
All I want to do in my SP is subtract an integer from getdate() and do a query based on the result
I get from that subtraction.
ex: getdate()-15 ?????????????????????????????????
Manipulating Dates In SQL
Jan 18, 2007I need to generate a date range, based on the current date (or an input date). I can get the correct dates using VB, but I haven't worked out the TSQL Syntax for them yet. Can anyone tell me the TSQL syntax for manipulating dates in the following way...?
Start Date... This is the first day of the month, one year ago... in VB I worked it out as...
dateadd("yyyy",-1,(cdate(cstr(Year(now))+"-"+cstr(Month(now))+"-01")))
End Date... This is the last day of the previous month... in VB I worked this one out as...
dateadd("d",-1,(cdate(cstr(Year(now))+"-"+cstr(Month(now))+"-01")))
eg. for today 18/01/2007 I would get a Start date of 01/01/2006 and an End date of 31/12/2006
Any help would be appreciated.
Manipulating Varchars As Datetime
Aug 10, 2007Hi all,
I am a little weak at SQL, so bear with me.
Can anyone give me an SP which uses "Between" to Display all Dates
BETWEEN a fromDate and toDate???
Two conditions
1.Both Dates are stored as varchar.
2. I should be able to get the dates even if years are different, say between 20th December 2006 and 3rd January 2007
3.Is there a way to extract the yearDiff?

Manipulating Large Tables
Feb 15, 2008I'm in the midst of a long file conversion job. Today I found that one of the tables (converted from csv) to be 6.7 million records. My sql script which I use to reconfigure the weird original date format, into something the rest of the planet uses, times out due to the size.
Does anyone please know of a file utility to automagically split sql server 2005 tables for later re-combining once my scripts have successfully completed their task on the smaller tables?
Manipulating A SqlDatSource UpdateCommand In Code-behind
Jul 20, 2007We've got an employee database that I'm modifying to include two photos of each employee, a small thumbnail image and a full-size image. The HR department maintenance page contains a listbox of employee names, which, when clicked, populates a detailsview control.To get the images to display and be updatable, I've had to structure the following SqlDatasource and DetailsView:
1 <asp:DetailsView ID="dvEmp" runat="server"2 AutoGenerateRows="false"3 DataSourceID="dsEmpView"4 DataKeyNames="empID">5 <Fields>6 <asp:CommandField ShowEditButton="true" ShowCancelButton="true" ShowInsertButton="true" />7 <asp:BoundField HeaderText="Name (Last, First)" DataField="empname" />8 <asp:TemplateField HeaderText="Thumbnail photo">9 <ItemTemplate>10 <asp:Image ID="imgThumbnail" runat="server" ImageUrl='<%# formatThumbURL(DataBinder.Eval(Container.DataItem,"empID")) %>' />11 </ItemTemplate>12 <EditItemTemplate>13 <asp:Image ID="imgThumbHidden" runat="server" ImageUrl='<%# Bind("thumbURL") %>' Visible="false" />14 <asp:FileUpload ID="upldThumbnail" runat="server" />15 </EditItemTemplate>16 </asp:TemplateField>17 <asp:TemplateField HeaderText="Full Photo">18 <ItemTemplate>19 <asp:Image ID="imgPhoto" runat="server" ImageUrl='<%# formatImageURL(DataBinder.Eval(Container.DataItem,"empID")) %>' />20 </ItemTemplate>21 <EditItemTemplate>22 <asp:Image ID="imgPhotoHidden" runat="server" ImageUrl='<%# Bind("photoURL") %>' Visible="false" />23 <asp:FileUpload ID="upldPhoto" runat="server" />24 </EditItemTemplate>25 </asp:TemplateField>26 </Fields>27 </asp:DetailsView>28 29 <asp:SqlDataSource ID="dsEmpView"30 runat="server"31 ConnectionString="<%$ ConnectionStrings:eSignInConnectionString %>"32 OnInserting="dsEmpView_Inserting"33 OnUpdating="dsEmpView_Updating"34 SelectCommand="SELECT empID, empname, photoURL, thumbURL FROM employees where (empID = @empID)"35 InsertCommand="INSERT INTO employees (empname, photoURL, thumbURL) values(@empname, @photoURL, @thumbURL)"36 UpdateCommand="UPDATE employees SET empname=@empname, photoURL=@photoURL, thumbURL=@thumbURL WHERE (empID = @empID)">37 <SelectParameters>38 <asp:ControlParameter ControlID="lbxEmps" Name="empID" PropertyName="SelectedValue" Type="Int16" />39 </SelectParameters>40 </asp:SqlDataSource>41 42 -----43 44 Protected Sub dsEmpView_Updating(ByVal sender As Object, ByVal e As SqlDataSourceCommandEventArgs)45 Dim bAbort As Boolean = False46 Dim bThumb(), bPhoto() As Byte47 If e.Command.Parameters("@ename").Value.trim = "" Then bAbort = True48 Dim imgT As FileUpload = CType(dvEmp.FindControl("upldThumbnail"), FileUpload)49 If imgT.HasFile Then50 Using reader As BinaryReader = New BinaryReader(imgT.PostedFile.InputStream)51 bThumb = reader.ReadBytes(imgT.PostedFile.ContentLength)52 e.Command.Parameters("@thumbURL").Value = bThumb53 End Using54 End If55 Dim imgP As FileUpload = CType(dvEmp.FindControl("upldPhoto"), FileUpload)56 If imgP.HasFile Then57 Using reader As BinaryReader = New BinaryReader(imgP.PostedFile.InputStream)58 bPhoto = reader.ReadBytes(imgP.PostedFile.ContentLength)59 e.Command.Parameters("@photoURL").Value = bPhoto60 End Using61 End If62 e.Cancel = bAbort63 End SubIf the user updates both images at the same time by populating their respective FileUpload boxes, everything works as advertized. But if the user only updates one image (or neither image), things break. If they upload, say, just the full-size photo during an update, then it gives the error "System.Data.SqlClient.SqlException: Operand type clash: nvarchar is incompatible with image".I think this error occurs because the update command is trying to set the parameter "thumbURL" without having any actual data to set. But since I really don't want this image updated with nothing, thereby erasingthe photo already in the database, I'd rather remove this parameter from the update string.So, let's remove the parameter that updates that image by adding the following code just after the "End Using" lines: Else
Dim p As SqlClient.SqlParameter = New SqlClient.SqlParameter("@thumbURL", SqlDbType.Image)
e.Command.Parameters.Remove(p)
(Similar code goes into the code block that handles the photo upload)Running the same update without an image in the thumb fileupload box, I now get this error: "System.ArgumentException: Attempted to remove an SqlParameter that is not contained by this SqlParameterCollection."Huh? It's not there? Okay, so lets work it from the other end: let's remove all references to the thumbURL and photoURL from the dsEmpView datasource. We'll make its UpdateCommand = "UPDATE employees SET empname=@empname WHERE (empID = @empID)", and put code in the dsEmpView_Updating sub that adds the correct parameter to the update command, but only if the fileupload box has something in it. Therefore: If imgT.HasFile Then
Using reader As BinaryReader = New BinaryReader(imgT.PostedFile.InputStream)
bThumb = reader.ReadBytes(imgT.PostedFile.ContentLength)
e.Command.Parameters.Add(New SqlClient.SqlParameter("@thumbURL", SqlDbType.Image, imgT.PostedFile.ContentLength))
e.Command.Parameters("@thumbURL").Value = bThumb
End Using
End If
(Similar code goes into the code block that handles the photo upload)But reversing the angle of attack only reverses the error. Uploading only the photo and not the thumb image results in: "System.Data.SqlClient.SqlException: The variable name '@photoURL' has already been declared. Variable names must be unique within a query batch or stored procedure."So now it's telling me the parameter IS there, even though I just removed it.ARRRGH!What am I doing wrong, and more importantly, how can I fix it?Thanks in advance.
Manipulating String To Return First Value Before Space

Manipulating Individual Fields Of A View
Nov 13, 2007In my database I have a table for Users, with an int primary key, and a table for Connections, with a combined primary key consisting of two UserID foreign keys. (the smallest first)
At the point I am stuck I have one UserID, lets call it current_user, and a column returned by a select statement consisting of UserIDs. Some of these IDs will likely be smaller than current_user, and some will likely be larger.
What i need to do is construct a view of two columns, combining each of the UserIDs in the column I have with current_user, with the smallest UserID of each pair residing in the first column, and the largest in the second column.
The point of this is to then SELECT the connections identified by the UserID pairs.
I suspect I could accomplish this if I could set individual fields in the a view, but I seem to have missed (or forgotten) that lecture. Anybody want to clue me in?
Manipulating Multiple Count(*) Queries
Dec 15, 2006Hi,
I'm having problems manipulating the results from multiple count(*) queries.
I have a table 'RECOMMENDATIONS' holding a field called 'SCORE'. This field holds a number from 1 to 10 and has no null or zero figures.
I currently have the following three queries:
1) SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (1,2,3,4,5,6)
2) SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (9,10)
3) SELECT COUNT(*) FROM RECOMMENDATIONS
I now need to combine these three queries so that i can divide and multiply the resulst: (query 2/query 1)*query 3
My initial idea was:
SELECT (COUNT(*)/(SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (1,2,3,4,5,6)))* (SELECT COUNT(*) FROM RECOMMENDATIONS) FROM RECOMMENDATIONS WHERE SCORE IN (9,10)
... but this gives a result of "0". I then stripped out the multiplication section to see if the divide was working:
SELECT COUNT(*)/(SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (1,2,3,4,5,6)) FROM RECOMMENDATIONS WHERE SCORE IN (9,10)
... and again the result was "0"
Please could someone help me!!

View 8 Replies View RelatedManipulating GetDate() To Start At Midnight Rather Than Now
Apr 29, 2008Hi Folks,
I am trying to find the best way to use the getDate() function in SQL Server CE to return a date and time which starts at midnight rather than the value of now which getDate() returns.
When running getDate I get the value of 29/04/2008 10:48:33 returned, but I want to return 29/04/2008 00:00:00 instead.
The only way I can see to do this is like so:
Code Snippet
--SQL to get shifts for next 7 days.
select * from SHIFTS
where STARTDATE between
--Today at midnight 2008-04-29 00:00:00.000
(convert(datetime,
convert(nvarchar,(datepart(yyyy,getdate()))) + '/'
+
convert(nvarchar,(datepart(MM,getdate()))) + '/'
+
convert(nvarchar,(datepart(dd,getdate())))
))
and
--7 days from now at night 2008-05-05 00:00:00.000
(
convert( datetime,
convert(nvarchar,(datepart(yyyy,getdate()+6))) + '/'
+
convert(nvarchar,(datepart(MM,getdate()+6))) + '/'
+
convert(nvarchar,(datepart(dd,getdate()+6)))
))
Is there a better way to do this rather than this long winded method?
Thanks,
Morris
Manipulating A Text Box In Custom Code.
Nov 21, 2006Hi there,
A simple question I hope. I have got a textbox on a report and I'm trying to populate it by calling a custom assembly. I know I can reference it directly in the textbox (this works) but I am trying to do this from the code block. The following code didn't work:
Protected Overrides Sub OnInit()
ReportItems!textbox2.Value = POCCustomAssembly.CustAssembly.Hello()
End Sub
The TextBox is called textbox2 and the custom assembly simply returns a string.
I get an error message "The is an error on line 1 of custom code: [BC30469] Reference to a non-shared member requires an object reference".
What am I doing wrong?
Manipulating Large Ntext Data With ADO Recordset

Jul 12, 2006I have to run a dynamic sql that i save in the database as a TEXT data type(due to a large size of the sql.) from a .NET app. Now i have to run this sql from the stored proc that returns the results back to .net app. I am running this dynamic sql with sp_executesql like this..
EXEC sp_executesql @Statement,N'@param1 varchar(3),@param2 varchar(1)',@param1,@param2,GO
As i can't declare text,ntext etc variables in T-Sql(stored proc), so i am using this method in pulling the text type field "Statement".
DECLARE @Statement varbinary(16)SELECT @Statement = TEXTPTR(Statement)FROM table1 READTEXT table1.statement @Statement 0 16566
So far so good, the issue is how to convert @Statment varbinary to nText to get it passed in sp_executesql.
Note:- i can't use Exec to run the dynamic sql becuase i need to pass the params from the .net app and Exec proc doesn't take param from the stored proc from where it is called.
I would appreciate if any body respond to this.

Help With Query Strings
Feb 7, 2007I am using query strings to pass data from web form to web form and I have two questions. First if i use a asp:sqldatasouce to fill up a grid view and I have my select command set to a paramater that get whatever is in the query string it will not work because whatever is in the quers string gets a " ' " put in front and in the back of it. So if the query string was 5 whene it does the sql statement it sets my paramater = '5' not just 5 so its wont work. How can I fix this using the asp:sql datasource my aspx code looks like
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:Rental PropertiesConnectionString %>"
SelectCommand="SELECT * FROM [APARTMENTS] WHERE ([PROPERITY_ID] = @PROPERITY_ID)">
<SelectParameters>
<asp:QueryStringParameter Name="PROPERITY_ID" QueryStringField="key" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
Also since i have not been able to get around this so i have been wrting code in vb.net to attact a dataset to a grid view to populate it based on the query string i would do the following in vb.net to get ride of the ' in front and behind the query string
Dim y as string = "'" // " ' "
key = Request.QueryString("key").trim(y.tochararray)
But now i am doing another project in C# and I have re-written the above code in C# it will run but it will not take the " ' " out form infront or behind key. How does this need to be changed up?
string y = "'";
key = Request.QueryString["key"].trim(y.tochararray());

Connection Strings
Nov 24, 2007I developed an application and deployed it onto a hosted provider. I use SQL 2005 Express for development SQL 2000 for production. Both systems work.
I backed up my production database and wish to use it for my development testing. I restored it as a SQL 2000 database on my development machine and changed my connection strings to point to it. I added it as a new Data Connection in Database Explorer and can see all of the data through it, but I see that all the tables now have the owner name in parenthesis as part of the table name.
My application now fails trying to find any of the tables. It works if I include the owner name as part of the SELECT statement. So much for data separation.
I don't know where to start. Is this an issue between SQL 2005 Express and SQL 2000, or is it an issue between SQL and ASP.NET, or is it a hosting provider issue, or what?????
Connection Strings
Jan 24, 2008Hey guys, don't know if this is in the right place but here goes.
I'd like some advice on optimizing the way I write my code. Here's the scenario. I have a select string for 3 different tables. One for the main gridview, and two others that are binded to dropdownlists.
So I created a Sqldatasource1,2,3 and had to create the connection strings for each one.
ex. SqlDataSource1.ConnectionString = "blah", SqlDataSource2.ConnectionString = "blah", SqlDataSource3.ConnectionString = "blah"the thing is, the connection string itself is the same. Is there a way to consolidate that? So that when I use a select/update/insert command for each sqldatasource i dont have to have another connection string? Also, having multiple connectionstrings, does that slow down the performance?
