SQL - Retrieving Same Table Twice
Jan 5, 2006
Hi,
I have a giant SQL query that retrieves a bunch of information from a couple of tables for use on a page, and I would like some help on constructing the SQL to get exactly what I have in mind. I have a table - called scContacts - that contains a list of contacts with detailed information. The contacts in the table are regular sales contacts, sales reps, and sales managers. Another table - called scCompany - contains a list of companies with detailed information.
For each company, we have a certain sales manager (or user) pertaining to that company as well as potentially a certain rep. The problem is that the contact tied to the company, the sales manager tied to the company, and the rep tied to the company all come from the same table. Here is the base SQL code I've used to get everything but the sales rep's name and sales manager's name:
----- SQL CODE -----
SELECT DISTINCT
scContacts.ID,
scContacts.inheritCoAddr,
scContacts.fName,
scContacts.lName,
scContacts.contact,
scContacts.billToAddress1,
scContacts.billToAddress2,
scContacts.billToState,
scContacts.billToZip,
scContacts.billToCity,
scContacts.billToCounty,
scContacts.billToCountry,
scCompany.ID AS companyID,
scCompany.companyName,
scCompany.companyURL,
scCompany.billToAddress1 AS companyAddress1,
scCompany.billToAddress2 AS companyAddress2,
scCompany.billToCity AS companyCity,
scCompany.billToState AS companyState,
scCompany.billToZip AS companyZip,
scCompany.billToCounty AS companyCounty,
scCompany.billToCountry AS companyCountry,
scCompany.businessType,
scCompany.phoneExt,
scCompany.phoneNum,
scCompany.faxNum,
scCompany.minEmployees,
scCompany.maxEmployees,
scCompany.actionTypeMAX,
scCompany.actionDateMAX,
scCompany.actionTimeMAX,
scCompany.statusID,
scCompany.userID,
scCompany.repID
FROM
scCompany,
scContacts
INNER JOIN
scStatus ON
scStatus.ID = scCompany.statusID
WHERE
scgroupContacts.contactID = [insert cookie value]
AND
scgroups.ID = [insert cookie value]
AND
scCompany.ID = scContacts.companyID
AND
scCompany.groupID = scgroups.ID
----- END SQL CODE -----
As indicated right now, this SQL code will retrieve all of the contact and company information for a certain contact ID which comes from a cookie value (inserted in ASP). I want to get the [fName] and [lName] fields from scContacts table where the scContacts.ID = scCompany.userID, and I also want those same fields from scContacts table again where the scContacts.ID = scCompany.repID. It would be simplest and most efficient if I could do this all at once (and I'm sure it's possible). How would I change the SQL to bring in that information from the same table two more times, tying their ID's to ID's in the company table?
thanks,

I have nine type of buttons,
EnrollAmtBTM
PlacAmtBTM and so on, I also have a SQL setver view V_Payment_Amount_List from here i need to display the data on the button
this is the select value to display when i choose the agency list and the amount corresponding to that agency_ID is displayed here the agency_ID is fetched from the SQL CONDITION
THIS IS WHERE I GET FETCH AGENCY DATA WHEN SELECTED i.e SQL CONDITIONprotected void CollectAgencyInformation()
{
WebLibraryClass ConnectionFinanceDB;ConnectionFinanceDB = new WebLibraryClass();
string SQLCONDITION = "";string RUN_SQLCONDITION = "";
SessionValues ValueSelected = null;int CollectionCount = 0;if (Session[Session_UserSPersonalData] == null)

}
SelectedAgency = SQLCONDITION;
ValueSelected.CONDITION = SelectedAgency;
???? this is where i use to get count where in other buttons and are displayed.... but i changed the query to display only the Payment_Amount_Budgeted respective to the agency selected. from the viewRUN_SQLCONDITION = "SELECT Payment_Amount_Budgeted FROM dbo.V_Payment_Amount_List " + SQLCONDITION;
try
{
CollectionCount = ConnectionFinanceDB.CollectedFinaceDataCount(RUN_SQLCONDITION);
EnrollAmtBTM.Text = CollectionCount.ToString();
}
catch
{
}////this is my CollectedFinaceDataCount-- where fuction counts the records in the above select statement if i use for eg.
"SELECT Count(Placement_Retention_ID) FROM dbo.V_Retention_6_Month_Finance_Payment_List"
here is the functionpublic int CollectedFinaceDataCount(String SQLStatement)
{int DataCollection;
DataCollection = 0;
try
{
SQLCommandExe = FinanceConnection.CreateCommand();
SQLCommandExe.CommandType = CommandType.Text;
SQLCommandExe.CommandText = SQLStatement;
ConnectToDatabase();DataCollection = (int) SQLCommandExe.ExecuteScalar();
DisconnectToDatabase();
}catch (Exception ex)
{Console.WriteLine("Exception Occurred :{0},{1}",
ex.Message, ex.StackTrace.ToString());
}
return DataCollection;
}
So here mu requirement request is to display only the value fronm the view i have against the agency selected
Please help ASAP

this is a simple problem but it's just driving me mad as it's not reading from my dB. basically, I've have reviews stored in my dB and want to display them in a textbox by clicking on a button called btnReviews. I think the problem might be that there is too much text stored per row of the table (as it is a review), but I have the datatype set as text in sql. here's the simple un-errorred code I have behind the button. any ideas where I went wrong. i've a feeling it's something small but it's just taken too long to figure out.protected void btnReviews_Click(object sender, EventArgs e) { String strConn = ConfigurationManager.ConnectionStrings["conLocalDatabase"].ConnectionString; SqlConnection dbConnection = new SqlConnection(strConn); SqlCommand dbCommand = new SqlCommand("Select [ReviewC] From [Review])", dbConnection); dbCommand.Parameters.AddWithValue("Review", txtReviewView.Text); try { dbConnection.Open(); dbCommand.ExecuteNonQuery(); } catch (SqlException ex) { Console.WriteLine(ex.ToString()); } finally { if (dbConnection != null) { dbConnection.Close(); } } }

The query below should be inserting unique records in the PropertyItem table which only has propertyitem, propertyid, and itemid columns, all of which are PK's in other tables. I'm not doing the insert correctly b/c it's inserting 72 records instead of 24. I really just want to automatically insert the values once I've inserted in the other tables but I'm not sure how. Maybe On Update Cascade?
--PROPERTYITEM
INSERT INTO [USCONDEX_Production].[dbo].[propertyItem]( [propertyId], [ItemId])
SELECT Property.propertyId, ITEM.ItemID
FROM ITEM RIGHT OUTER JOIN
miamiherald ON ITEM.StartDate = miamiherald.FirstInsertDate AND ITEM.Price = miamiherald.PropertyPrice AND ITEM.Classified = convert(int,miamiherald.AdNumber) LEFT OUTER JOIN
Property ON property.adprintid = miamiherald.adprintid
WHERE validAD=1

I wonder if you can help...
I have a simple setup: 2 tables and a joining table, and want to retrieve a data set showing every possible combination of table A and table B together with whether that combination actually exists in the joining table or not.
My tables:
channels
======
channel_id
channel_name
items
====
item_id
item_name
channels_items (joining table)
===========
channel_id
item_id
created
An example of the dataset I want (assuming 2 items and 2 channels, with itemA not being in channelB):
item_id item_name channel_id channel_name exists
======= ========= ========== ============ ======
1 ItemA 1 ChannelA True
2 ItemB 1 ChannelA True
1 ItemA 2 ChannelB False
2 ItemB 2 ChannelB True
I'm completely stuck on how to achieve this. Any guidance would be very much appreciated.

Hello,I am in the midst of converting an Access back end to SQL Server Express.The front end program (converted to Access 2003) uses DAO throughout. InAccess, when I use recordset.AddNew I can retrieve the autonum value for thenew record. This doesn't occur with SQL Server, which of course causes anerror (or at least in this code it does since there's an unhandled NULLvalue). Is there any way to retrieve this value when I add a new recordfrom SQL server or will I have to do it programmatically in VB?Any direction would be great.Thanks!

I would like to retrieve a hierarchical list of Product Categories from a single table where the primary key is a ProductCategoryId (int) and there is an index on a ParentProductCategoryId (int) field. In other words, I have a self-referencing table. Categories at the top level of the hierarchy have a ParentProductCategoryId of zero (0). I would like to display the list in a TreeView or similar hierarchical data display control.Is there a way to retrieve the rows in hierarchical order, sorted by CategoryName within level? I would like to do so from a stored procedure.

I have 2 tables - tblOrders and tblOrderDetails. Every time an order is placed, 2 INSERT statements are executed. The first one enters the general order and customer information in the tblOrders table:INSERT INTO tblOrders (custname, custdetails, orderdate) VALUES (@custname, @custdetails, @orderdate)The primary key in this table is OrderID which is an Identity column. This is the foreign key in the tblOrderDetails table.I'm trying to get the Identity value from the first INSERT statement to use in the second INSERT statement:INSERT INTO tblOrderDetails (orderid, productid, productcost) VALUES (@orderid, @productid, @productcost) How do i obtain this value and how would I supply it to the second INSERT statement?

I have a detail table of comments. I need to grab the fist 50 characters from the comment field from this table. The kick is that I need to get the comments from all of the records in the detail table, as the comments might be less than 50 characters, so i need to pull the comments from the other comment records that apply to the master table record.
right now i have the comments in a join to the master table, but this is causing a few records to be returned....
I guess what i am looking for is a way to grab the comment value from the first record of the detail table.

I have a query that gets the tables, columns, indexes, index_columns for all tables in a data base.
But, I need to be able to select any data base on the server
and then drill down into the tables, columns, etc.
I looked at sys.databases but can't see how to relate that to the
sys.tables to extend my query.
Is there a way?
I've looked at the information_schema area and catalog views

I am working on creating a report which is retrieving data from a SQL 2005 database and being displayed in a C#.net web page. Presently, I am binding the dataset to a ASP:Gridview on the web page.
I am currently retrieving most of the needed fields using the following SQL statement:PROCEDURE [dbo].[pr_getReportTickets] @DateCreated nvarchar(15) ASBEGIN
-- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
-- Insert statements for procedure hereSELECT tbl_Queue.num_TicketNumber AS TicketID , tbl_Users.str_Name AS Technician , tbl_Queue.str_QueueLocator AS TechNTID , tbl_Queue.dat_ReceivedRequest AS dateCreated , tbl_Queue.dat_DueDate AS DueDate , tbl_Queue.str_TaskName AS TicketTitle , tbl_Queue.str_Requestor AS RequestorNTID --, I need most current dat_TimeStamp from tbl_Notes here for this record --, I need most current int_PercentComplete from tbl_Notes here for this record --, I need to sum up all of int_MinutesWorked fields from tbl_Notes here for this record , MasterEmp.dbo.fn_FormatFullName(tbl_employee.str_fname, tbl_employee.str_lname) AS RequestorName , tbl_Queue.str_TicketType AS TicketType , tbl_Status.str_TaskStatus AS TicketStatus , tbl_Severity.str_Priority , tbl_Complexity.str_Complexity , tbl_Severity.str_Priority + N' / ' + tbl_Complexity.str_Complexity AS Priority , tbl_Queue.dat_CompleteDate as DateCompleted
FROM dbo.tbl_Queue LEFT OUTER JOIN MasterEmp.dbo.tbl_employee AS tbl_employee ON dbo.tbl_Queue.str_Requestor = tbl_employee.str_ntid LEFT OUTER JOIN tbl_Users ON tbl_Queue.str_QueueLocator = tbl_Users.str_ntid LEFT OUTER JOIN tbl_Status ON tbl_Queue.num_Status_CD = tbl_Status.num_Status_CD LEFT OUTER JOIN tbl_Severity ON tbl_Queue.str_Severity = tbl_Severity.str_Severity LEFT OUTER JOIN tbl_Complexity ON tbl_Queue.int_ComplexID = tbl_Complexity.int_ComplexID
WHERE (dbo.tbl_Queue.dat_ReceivedRequest > CONVERT(DATETIME, @DateCreated, 102))
ORDER BY TicketType, tbl_Queue.str_Severity
I also have another table called tbl_Notes. This table contains an unlimited quantity of records for every “num_TicketNumber�. This table contains the following fields: num_TicketNumber, str_TechRep, str_Notes, dat_TimeStamp, int_PercentComplete and int_MinutesWorked
I need to add two more fields to the query, but I do not know how to tell the SQL statement how to retrieve the data for the specfic record and inbed the fields into the Dataset being returned from the database to the web page.1) The first field I need is the most current recorded Date field from the tbl_Notes table for the each of the records returned in the above SQL statement. Similar to: SELECT TOP (1) dat_TimeStamp FROM tbl_Notes WHERE(num_TicketNumber = xxxx) ORDER BY dat_TimeStamp DESC2) The other field I need to return with the Dataset is the sum of the int_MinutesWorked for each of the tickets being retrieved. Similar to: SELECT SUM(int_MinutesWorked) AS TotalMinutesFROM tbl_Notes WHERE (num_TicketNumber = 49)

I am currently investigating the best way to handle partition swapping where the partition scheme is built on several file groups. In order to swap partitions, both partitions need to be on the same file group. In addition, the file groups and partitions are automatically updated once a month meaning that there is a scheduled job that adds a new file group, file group files, and updates the related partition objects.If I am forced to create a new non-partition table on the same file group as the partition of the target table, what would be the best way to create the target table without hard coding the full table definition and clustered index? I know that I can query the systables and syscolumns views to reconstruct a basic SQL statement to build the table definition and views Is there a SQL Server function that I can use to just give me the object definitions? Unfortunately, the OBJECT_ DEFINITION function doesn't apply to tables or indexes. URL....

How can I efficiently retrieve the top x managers within the top y regions within the top z states within the top q countries?
The only way I have been able to do this is to first find the top q countries, and store the list in an IN clause. Then for each of those, find the top z states and create another IN clause that contains the country+state concatenated. Then for each of those, find the top y regions and concatenate country+state+region. Then finally find the top x managers within this IN clause.
This works fine for a few hundred records, but once it reaches the thousands, it takes much too long. The final IN clause contains thousands of entries.
Isn't there a simpler way to approach this, especially with SQL Server 2005?

Hi
I've got a module that contains the following function.
Imports System.Data.SqlClient
Module SQL_Sprocs
Function ListUsers()
Dim conn As New SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("DBConn"))
Dim cmd As SqlCommand = New SqlCommand("list_users", conn)
cmd.CommandType = CommandType.StoredProcedure
conn.Open()
Dim dr As SqlDataReader
dr = cmd.ExecuteReader
ListUsers = dr
dr.Close()
conn.Close()
End Function
End Module
I then want to call this function from my webform. So I'm using the following
Dim dr As SqlClient.SqlDataReader
dr = Timetracker.SQLProcs.ListUsers()
Do While dr.Read
Label1.Text &= dr("first_name") & " " & dr("last_name") & ", "
Loop
dr.Close()
But it's not working. I want to have a module that contains all my sprocs and be able to call them from the individual webpages.
What am I doing wrong?

I have records in a table and 1 column is in the smalldatetime format which stores the date in the format "2004-09-22",2004-09-20",2004-09-12",2004-08-04" etc etc.
Can anyone tell me how to craft an SQL statement so that i can retrieve records for a certain month.For example,if i want to retrieve records for the month of September,i would get "2004-09-22",2004-09-20",2004-09-12" in results.

"I meant to delete just one assignment, doing which was giving me difficulty.
I deleted a whole category by accident which had most of my daily grades in it for a course with quite a few of them. I was negligent in backing them up, so I cannot restore them. I have an XLS file from the midterm, but am missing about 6 grades after that.
Is there any way to recover the grades I had in the deleted category. It has been a couple of days since I entered any new grades. HELP!"
My current backup strategy is to do a full backup 5 pm, differentials every 2 hours, logs every 30 min, all so they arenot simultaneous. Backing these all to same backup device via three different jobs.
Then the server is backed up to tape shortly after the 5 pm full backup.
Obviously, I can't restore from the backup for this situation because it would hurt other data.
But - is there a way I can take last night's backup from tape and restore it to a different database than our production database? (Such a database doesn't at this time exist. Would I detach, copy over the files, and then reattach on prod and attach on the devl side, and then restore from the backup device to the devl copy?)
I've never had to perform this kind of rescue and am wondering if my backup strategy is flawed since it isn't immediately evident how I can easily do this.
I needed a similar thing from our Oracle DBA yesterday, and he went to tape, copied out a table and put it on the Oracle database under a different owner, and I easily fixed the few records that I had botched.
That's exactly what I need to do now with MS SQL 2000.
As the faculty dude said, "HELP!"
And Thanks.

Hi,
I was hoping someone would be able to help me, I trying to go through several databases, 111 to be exact, and get the data out of a particular table which is present in all the databases on the same server.
I know how to get the names of the databases from the INFORMATION_SCHEMA, but how can use the name for it to cycle through all the databases and get data out of the one particular table.

Hi, I need some help. I have this query where i need to pull up students that have more than or equal to 3 absences in a row. Now I am getting all those students that are absent but not in a row. But i was wondering if there is a way to tell if a student was absent three days in a row . There is a date field that is being used to identify the day of the class and a status field that identifies if the student was absent or present. Please help someone.
