The relation "Product" shows the maker, model number, and type (pc, laptop, or printer). It is assumed that model numbers are unique for all the makers and product types. Each model number specifying pc in the relation "PC" is characterized by speed (of the processor in MHz), total amount of RAM (in Mb), hard disk drive capacity (in Gb), CD ROM speed (for example, '4x'), and the price. The relation "Laptop" is similar to that one of PCs except for the CD ROM speed, which is replaced by the screen size (in inches). For each printer model in the relation "Printer" it is told whether the printer is color or not (color attribute is 'y' for color printers; otherwise it is 'n'), printer type (laser, jet, or matrix), and the price.
The task is:
For each group of laptops with the identical model number, add following record into PC table:
code: minimal code among laptops in the group +20;
model: laptop's model number +1000;
speed: maximal speed among laptops in the group;
ram: maximal ram size among laptops in the group *2
hd: maximal hd capacity among laptops in the group *2;
cd: default value;
price: maximal price among laptops in the group divided by 1.5;
I have performed the following request
insert into pc(code,model,speed,ram,hd,cd,price)
SELECT distinct (Min(b.code)+20),l.model+1000, max(l.speed),(max(l.ram))*2,(max(l.hd))*2,CAST(MAX(cast(left(pc.cd,len(pc.cd)-1)as int))as char(2))+'x',max(l.price)/1.5
from Laptop as l,PC,(
select a.code from laptop as a, laptop as b
where a.model = b.model ) as b
GROUP BY l.model
... but it returns incorrect result on several positions. Where is mistake ?
I just got finished developing the company intranet site and thinking that everything was working I boasted about how good it was by getting my boss to login and submit a new job to the db (new job, its a work management app) while i did the same, the pland was to hit the submit button at the same time. He would send one to be read by me and I would send one to be read by him. We both hit submit and the following happened.
The db has somehow fused the two into one. I thought maybe we were to accurate in hitting the submit button together. But I even gave a five second delay between and for some reason the job is being overriden by one user tor the other. In other words we are both sharing the same jobid. I thought this could never happen with sql server supposing that it would lock one request until another was completed and vice versa. But I'm so new to this that I'm just so naieve to think that the db would do this for you. Problem is I'm about to move on and I can't leave the app in this state. Can anyone point to some articles or give some suggestions has to my situation. Most desperately in need!!
i'm having touble getting my sp done. the problem is as follow..i've found an sp tokenize (which works fine) with the following signature:
CREATE PROCEDURE TOKENIZE ( S VARCHAR(10000), DELIM CHAR(1)) RETURNS ( ID INTEGER, TKN VARCHAR(10000)) AS DECLARE VARIABLE I INTEGER; DECLARE VARIABLE LEN INTEGER; DECLARE VARIABLE FIRSTCHAR CHAR(1); DECLARE VARIABLE S2 VARCHAR(10000); begin ... SUSPEND; end^
then i build myself another sp (which also works fine) with this signature:
CREATE PROCEDURE GET_DICENTRIES_BY_ASDSKRPT ( ASDSKRPTINPUT VARCHAR(15)) RETURNS ( ID BIGINT) AS begin ... suspend;
end^
now, what i'm trying to do is write another sp (get_dicentries_by_all_asdskrpts) that accepts a '.'-tokenized string as a parameter (e.g. 'bla.bli.blo.blu'; number of tokens NOT fixed at 4!) and returns the intersection of
GET_DICENTRIES_BY_ASDSKRPT('bla'), GET_DICENTRIES_BY_ASDSKRPT('bli'), GET_DICENTRIES_BY_ASDSKRPT('blo') AND GET_DICENTRIES_BY_ASDSKRPT('blu')
Could someone help me get the following SQL statement working?SELECTstandardgame.gamename,standardgame.rowteamname,standardgame.colteamname,standardgame.dollarvalue,standardgame.gameid,standardgame.cutoffdatetime,standardgame.gametype,standardgame.gameowner,(100-COUNT(purchasedsquares.gameid)) AS squaresremainingFROM standardgameLEFT OUTER JOINpurchasedsquares ON standardgame.gameid = purchasedsquares.gameidwhere gametype='$gametype' and dollarvalue = '$dollarvalue' andgameowner = 'GROUP BY standardgame.gameidorder byCASE squaresremaining WHEN 0 THEN 1 ELSE 0 END ASC,squaresremaining ASCThe problem is... MySQL doesn't seem to want to let me usesquaresremaining in that case statement since it's not an officialcolumn name. Any idea how I can reference squaresremaining in the casestatement?

I have a table adapter query with a like clause that I can't get to work. The field is "Type", so I have "LIKE '%@Type%'". When I click the Execute Query button to test, not only does nothing get returned, I don't get the chance to enter the parameter. If I change LIKE '%@Type%' to say, LIKE '%book%', the appropriate records are returned. I actually need to check two parameters. If I ad the second parameter, the where clause becomes(Type LIKE '%@Type%') AND (SendState = @SendState)When I test the query, a screen pops up to let me enter the state, but not the Type. I can't see anything wrong with the query, but something must be. Diane
I am having a most frustrating time getting this working. I have two machines, one named 'REMOTE' and it contains my SQL Server (2005 developer edition). Then I have my main PC, named 'DOUGAL' The server instance on the REMOTE computer is called 'SQLSERVER' and there is only one instance. The server is showing as running etc and I can log in locally on the REMOTE computer easily via the Microsoft SQL Server Management Studio etc. I have two logins that are working fine, sa and a login called 'db_user'.Now I am trying to connect in the server explorer in visual studio. When I try and connection i get the following error; An Error has occured while establishing a connection to the server. When connectiong to SQL Server 2005 this failure may be caused by the fact that under the default settings SQL server does not allow remote connections. (provder: Named Pipes Provider, error: 40 - Count not open connection to SQL Server). I have tried connection to 'REMOTE/SQLSERVER' 'REMOTE' and with its IP address to - without any luck. So, to fix this problem I have checked that remote connections are allowed (and restarted the system). I have also checked that named pipes and tcp/ip connections are enabled. I have searched around with the aid of my best friend, Google. However, I've only found suggestions that involve trying the fixes I already tried.
Ok, what I am tryin to do is quite simple i do believe. Basically I have an aspx page with a textbox, a button and a datagrid linked to my sql db. What I am wanting is for a user to enter in their Social Security Number in the text box and click the button. If the SSN matches a record in the DB then it binds to the datagrid and shows it, IF no match is found then it displays a link to click on to continue onto the next page. This is to stop duplicate entries. I can get one to work by itself but not both of them at the same time. Here is my code.<%@ Page Language="VB" %><%@ Import Namespace="System.Data" %><%@ Import Namespace="System.Data.SqlClient" %><script language="VB" runat="server"> Sub btnSearch_OnClick(sender as Object, e as EventArgs) Dim objConnection As SqlConnection Dim objCommand As SqlCommand Dim objAdapter As SqlDataAdapter Dim objDataSet As DataSet Dim strSearch As String Dim strSQLQuery As String ' Get Search strSearch = txtSearch.Text ' If there's nothing to search for then don't search ' o/w build our SQL Query and execute it. If Len(Trim(strSearch)) > 0 Then OK, Here is my first IF, this works. ' Set up our connection. objConnection = New SqlConnection("Data Source=BRADBLACKBUR-PCMSSMLBIZ;" _ & "Initial Catalog=Victorypoint;Integrated Security=True;") ' Set up our SQL query text. strSQLQuery = "SELECT FirstName, LastName, SSN " _ & "FROM Applicants " _ & "WHERE SSN LIKE '%" & Replace(strSearch, "'", "''") & "%' " _ & "ORDER BY SSN;" ' Create new command object passing it our SQL query ' and telling it which connection to use. objCommand = New SqlCommand(strSQLQuery, objConnection) ' Get a DataSet to bind the DataGrid to objAdapter = New SqlDataAdapter(objCommand) objDataSet = New DataSet() objAdapter.Fill(objDataSet) If objDataSet.Tables.Count < 1 Then Right here is where I am having the problem, I need to count the Rows not the Tables, but I dont know what code i should use here. Button1.Visible = True Else ' DataBind DG to DS dgSearch.DataSource = objDataSet dgSearch.DataBind() objConnection.Close() End If End If End Sub
I've tried to post this somewhere else, but I haven't gotten it figured out yet: I'm passing variables through a URL, and the page that accepts the variables has a where clause like this:"WHERE (name1 LIKE @name1 + '%') and (property_add like @property_add + '%') and (ctlmap = @ctlmap )"On the search page where the variables are entered, the user may not know all the information that goes into each input field. (If the user just knew the name, they would search by name. If the user just knew the address, they would search by address...etc.) Everything works great before I add the ctlmap variable. When the ctlmap variable is added, no search results will turn up unless there is an entry made to the ctlmap field. I know it has to have something to do with the ctlmap being set to equals rather than like, but I can't find a way to make the search work with a null value for ctlmap. Thanks, everyone. Additional Info: <SelectParameters> <asp:QueryStringParameter ConvertEmptyStringToNull="False" Name="name1" QueryStringField="name" Type="String" /> <asp:QueryStringParameter ConvertEmptyStringToNull="False" Name="property_add" QueryStringField="address" /> <asp:QueryStringParameter ConvertEmptyStringToNull="False" Name="ctlmap" QueryStringField="ctlmap" /> </SelectParameters> Here's another type of where clause that I tried but had no luck with: WHERE (name1 LIKE @name1 + '%') and (property_add like @property_add + '%') and (@ctlmap IS NULL or @ctlmap = ctlmap) This is how I would try to do it in php/mysql, but I don't know how to make it work in asp.net/sql: if ($ctlmap != "") { $whereClause = $whereClause." and ctlmp = '".strtoupper($ctlmap)."' "; } if ($whereClause != "") { $whereClause = " where ".$whereClause; }Here's the MYSQL counterpart:$sqlString = "Select distinct district, map, bill_group, ctlmap, bill_parcel, propertyid, special, property_add, name1 from MUR_bill_master".$whereClause";
I am having difficulty connecting to a SQL DB in my ASP page. Each time I run my application I receive the following error, "Login failed for user 'CX259ASPNET'". This is obviously something to do with permissions. I am all out of ideas but I will list the things I have already attempted to see if I either missed something or somebody can add to what I have already done.
1. In SQL Server I right-clicked the db -> properties -> security tab -> selected the option button to "SQL Server and Windows" instead of "Windows Only". 2. I installed SP3 and changed the sa password. 3. I created a new user under my db using the ASPNET account listed. I then changed the permissions to allow selecting, update, insert and delete access. 4. I also created a new user under my db using the IUSR account listed. I changed the permissions to the same settings as above.
I did a search on google which provided with all of the information above, but I am still stuck and hoping that this is a common problem and will be easy to fix.
Below is the code which I am attempting to use.
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If Not Page.IsPostBack Then Dim strConnString As String = _ "Data Source=(local);" & _ "Initial Catalog=Names;" & _ "Integrated Security=SSPI;" Dim objConn As New SqlConnection(strConnString) Dim strSQL As String = "SELECT * FROM [Names]" Dim objCmd As New SqlCommand(strSQL, objConn)
objConn.Open() MyDataGrid.DataSource = objCmd.ExecuteReader MyDataGrid.DataBind() objConn.Close() End If End Sub
What i am trying to do is concatenate variable "@Where" with CURSOR sql statement,inside a procedure . But, it doesn't seem to get the value for the @Where. (I tried with DEBUGGING option of Query Analyzer also).
============================================= SET @Where = '' if IsNull(@Input1,NULL) <> NULL Set @Where = @Where + " AND studentid='" + @input1 +"'"
if isnull(@Input2,NULL) <> NULL Set @Where = @Where + " AND teacherid =' " + @Input2 +"'"
DECLARE curs1 CURSOR SCROLL FOR SELECT * FROM school WHERE school ='ABC' + @where =============================================
It gives me all the Records inside the SCHOOL='ABC' ...
Please check my SQL Above and Could somebody tell me , how can I attach the VARIABLE with CURSOR sql statement ?

Hello, I've got some trouble when using xp_readmail.I check the email count and saved the attached files in c:winnt. The problem is when the attached files are saved cause the file name is cut in dos format (8 characters + . + 3 characters) but my file's name is like toto.tutu.titi_tata.txt so is there a way to keep the name unchanged when saving attached files ? Thanks for your answers
I've been having this huge problem with date and SQL 7, like lot of people. I use asp with the sql and trying to do this query where startdate should equal or smaller the date today, here are to queries that worked, but not anymore.
SELECT * FROM tbl_date WHERE convert(varchar(10), startdate, 101) = convert(varchar(10), getdate(), 101)
this query worked until the year 2000, the normal y2k bug then this one, wich i saw here on messageboard:
select * from tbl_date where startdate =< '" & date & "'" well this worked until today, when it just stop working
Server A is Publisher/Distributor SQL7 Server B is Subscriber SQL7
Successfully set up a publication for table on Server A
Synchronisation fails with error that 'The network name cannot be found' and the following file could not be created: The last action is 'Server AC$MSSQLRepldataunc<pub name><date string>ablename.sch'
... which is odd because the file IS created and contains a correct looking table definition.
So, manually sync data on this one table and try again, now it can't connect with my server, which is weird cos I can connect through EM.
IF @email = (SELECT email FROM customers WHERE @email = email) PRINT 'This customer is already in the database' ELSE PRINT 'New Customer Added' INSERT INTO customers VALUES (@fname,@lname, @companyName, @address, @zip, @city, @country, @email)
Looks pretty straightfoward, however when I add a duplicate customer, I get the 'This customer is already in the database' message and then the record is added. I don't know why this is happening. Can anyone help?
I am attempting to port a database from one server to another, I am using the DTS wizard to so this, the Db copies over to the other server but it drops the views, usernames, stored procs etc. Is there another way to do this? possibly with T-SQL? Any suggestions would be great.
I have a cube with a lot of dimensions. Two of them are ItemNo and LocationCode. I need to have two measures "Locations Shipped To" and "Item Count". For those, I need to have a count of different locations/items matching current dimension filters. So I tried adding a calculated member:

Here is what I have. Windows 2000 server, Sql server 2000 standard, Solomon 5.5
I have a view that is used by crystal reports. We had a company come in and they designed a custom report. The view uses three other views. The report works perfectly until two people try to run the report at the same time. This is when four of the columns in the report double the values.
We ran the report for a year or two with no problem. Now that we are starting to use Solomon Desktop for people out in the field we are finding this problem.
Is there a way that the view can be setup not to cause this problem?
Hi! When I double click on “sa” account in the Logins folder under Security I’m getting the error message:
“ Error 21776: [SQL - DMO] The name ‘dbo’ was not found in the users collection. If the name is a qualified name, use [ ] to separate various parts of the name, and try again.”
What does it mean? What is corrupted? Thanks. Elena.
ok, we have a development server in our office and it has SQL running on it. If i remote over to that machine i can open the database administrator and create tables and things just fine. I use the windows login.
now when i try to goto my machine and open up visual studio or dreamweaver to try to make a dataset connection it will not connect to the server. I get a message in visual studio saying it is probly because the default settings prohibit remote connections to the DB. I'm also doing the wondows login mode from the remote computer.
So is there a way i can change it so i can have remote access? i dont see how else they expect anyone to be able to do any development from a remote machine elsewise...
I have a pretty nasty situation in where I have two tables that hold quantity values for an interval of time. One table has an hourly date format while the other is every 5 minutes. I'm using the below t-sql to pull back the summed quantities I need in an HOURLY format; however, it is doubling the MarketQty field becuase it's not summing the qty field from the HE (henwood_extract) table correctly:
I am using standard ASP to connect and select records from a SQL Server 2000 database. My goal is to select the 3 most recent records that match my criteria.
Problem: When I run my query and display the records without the 'TOP 3' statment all records matching my criteria are predictably returned. However, when I add the 'Top 3' statement only one record is returned.
Here is the SQL code I am using to select my records:
and here is the code I use to display the records. There isn't any formatting yet as I am attempting to get the expected results before adding any formatting to the page:
Code:
if not rs.eof then do while not rs.eof response.Write(rs("GroupImageName")) rs.movenext loop end if
Even if I remove the 'ORDER BY' statment I am still only seeing 1 record. If I remove the 'top 3' statement 9 records are returned!
I have a DTS Routine which archives a large amount of data into archive tables in the same database(Personally I would rather archive into a separate db but the paperwork for the customer involved in doing this is ridiculous).
The routine seems to archive all tables except for one (the largest one) However if I split the routine and run the rest of it first then the problem table then the table archives ok. To me it smells of transaction size or something but does anyone have any other ideas.. If it is transaction size, is there a way that I can break the routine down into multiple transactions?
Any help is as always greatly appreciated.

I'm trying to delete duplicate records from a table. The table is full of "new" records that need to be added to the database with some user input. Since the table is populated from multiple sources, duplicate entries can be put in. I'd like to clean those out after each "run".
Here's what I have so far, but of course, it's not right:
create table tmpKickouts ( KICK_IDINTEGER IDENTITY, PARTCODEVARCHAR(10), KICKOUT_REASON INTEGER ) INSERT INTO TMPKICKOUTS ( PARTCODE, KICKOUT_REASON) SELECT 'ABC', 1 UNION ALL SELECT 'ABC', 1 UNION ALL SELECT 'ABC', 2 UNION ALL SELECT 'DEF', 2 UNION ALL SELECT 'GHI', 1 UNION ALL SELECT 'GHI', 1 UNION ALL SELECT 'GHI', 1
SELECT * FROM TMPKICKOUTS TK WHERE NOT EXISTS ( SELECT MIN(KICK_ID) AS KICK_ID, PARTCODE FROM TMPKICKOUTS WHERE PARTCODE IN ( SELECT DISTINCT PARTCODE FROM TMPKICKOUTS WHERE KICKOUT_REASON=1) AND KICKOUT_REASON=1 AND TMPKICKOUTS.KICK_ID=TK.KICK_ID AND TMPKICKOUTS.PARTCODE=TK.PARTCODE GROUP BY PARTCODE) AND KICKOUT_REASON=1
DROP TABLE TMPKICKOUTS
In this example, I'd want to delete records 2, 6, & 7
In a SQL 2000 SP 1 installation I've a problem with a view.
When I run a select from this view with a where clause the view return me a result set, but if I insert a order by clause the result set is empty. I try to re-organize indexes and update statistics without results.
The server is on a client site so I can't update the SQL 2000 installation immediatly, I try to ask about the installation of the SP 3.
But in the meanwhile I need some information. Anyone see this problem before.
