OK, this is a big problem, with multiple tables, but here goes. Here's my schema:
--------------------------------------------------
Events
--------------------------------------------------
ID | E_Title
--------------------------------------------------
--------------------------------------------------
EventOptionGroups
--------------------------------------------------
ID | EOG_EventID | EOG_OptionGroupID
--------------------------------------------------
--------------------------------------------------
OptionGroups
--------------------------------------------------
ID | OG_Title
--------------------------------------------------
--------------------------------------------------
Options
--------------------------------------------------
ID | O_OptionGroupID
--------------------------------------------------
--------------------------------------------------
EventRegistration
--------------------------------------------------
ID | ER_EventID
--------------------------------------------------
--------------------------------------------------
RegistrantOptions
--------------------------------------------------
ID | RO_EventRegistrationID | RO_OptionGroupID
--------------------------------------------------
OK, what I'm trying to do is, when I delete an event, I need to delete all the data associated with that event. So here's the thought process.
Delete Event based on ID
Delete all EventRegistration where ER_EventID = Event.ID
Delete all RegistrantOptions where RO_EventRegistrationID = EventRegistration.ID
Delete all EventOptionGroups where EOG_EventID = Event.ID
Delete all OptionGroups where OptionGroups.ID = EOG_OptionGroupID
Delete all Options where O_OptionGroupID = OptionGroups.ID
Sorry that it's so complicated, by I need help. There are foreign key constraints on the tables as well, so you have to work from the bottom back up.
I am converting all the inline sql in my ASP.NET app to stored procs and I am experiencing some difficultly with my shortest and least complex stored proc. I am new to both ASP.NET and SQL especially using stored procedures so this may have some extremely obvious flaw in it. I am trying to delete a entry that has parts in two tables. I created a stored procedure along the lines of: CREATE PROCEDURE DeleteEntry(Â Â Â Â Â @EntryIDINT)ASDELETE FROM firstTable WHERE entry_id = @EntryIDDELETE FROM secondTable WHERE entry_id = @EntryIDI have a remove button on a asp page that executes the stored procedure but it only removes the entry from the second table the first time I click it and then when I click it a second time it removes the entry from the first table.
I have 30 or 40 tables in a database called Temp with names like PV_ and i am trying to figure out how to loop through and delete them. I've searched all over the web and forums looking for an answer but can't seem to find it. Does anyone know how to delete tables with the keyword like?
Hi: I have 3 tables namely: 1 Category(CategoryID(int), CategoryName(varchar), 2 SubCategory( CategoryID(int),SubcategoryID(int),SubcategoryName) 3 Productlist (ProductID(int),ProductName(varchar),CategoryID(int), CategoryName(varchar),SubcategoryID(int),SubcategoryName(varchar)) how to delete correspoding subcategories of category from SubCategory,Productlist tables using triggers Ex: Category :TV Subcategory:ColorTV,Plasma,LCD...Plz Send me the query.... Thanks
I have an SQL 2000 server. I have multiple tables in the db that have a row with a time stamp of '10-23-2007'. What I am trying to do is delete these specific rows because they don't belong. So I need to query the db for table names that are like 'elect_Sub%' and then execute a query on those tables that would delete the row with the time_stamp '10-23-2007'. I know that I have to use the db schema to get the table names, but I need help in writing the sql script that will automatically scroll through the tables.
This a microsoft SQL 2000 server. I have a DB with mutliple tables that have a column called "Date_stamp", which is used as a primary ID. Here is my problem: Some of tables have a bad datetime entry for the "Date_stamp". The bad entry is '2008-3-18". I need to delete this entry from every single table that has a name similary to 'Elect_Sub%Daily'.
I know how to get the user table names from the DB as follows:
SELECT name FROM dbo.sysobjects WHERE xtype = 'U' and name like 'Elect_Sub%Daily'
What I need to do is have a query that will basically scroll through the tables name produced by the above query and search and delete the entries that read '2008-3-18".
delete from tableName where Date_Stamp = '2008-3-18'
Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data. When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.

I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.
I have just taken over the job of sorting out a rather poorly designed database. It looks like it was 'upsized' from an access database to the SQL server. The SQL server is the 2000 version.
Now I am trying to generate a report of what the students in the database are owing by referencing the Receipt table and then all the available payment methods and allocations. I was wondering if there was anyway to work out data being displayed twice (Let me demonstrate)
Note1: All the tables are linked by a key of ReceiptNo. From what I can see there is a table for every payment type and allocation but no link between the two other then the receipt number.
Using the query: SELECT T_Receipt.ReceiptNo, T_cheque.Amount AS Chq_Amount, T_credit.Amount AS Cre_Amount, StandingOrder.Amount AS Stn_Amount, T_BankTransfer.amount AS Bnk_Amount, T_cash.TotalAmount AS Cas_Amount, T_RentPayment.AmountPayed AS Ren_Paid, T_AdminPayment.AmountPaid AS Adm_Paid, T_InternetBilling.Total AS Int_Paid, T_Utilities.AmountPaid AS Util_Amount, T_InvoicePayment.amountPaid AS Inv_Paid, T_OtherPayments.paymentAmount AS Oth_Paid, T_parkingBill.paymentAmount AS Prk_Paid, T_TelephoneBills.TelephoneCredit AS Tel_Paid, T_DepositPayment.[Deposit payment] AS Dep_Amount, T_Receipt.cancelled AS Canceled, T_Receipt.RemittanceReceiptNo AS Rec_Ref, T_Receipt.Student FROM T_Receipt INNER JOIN T_DepositPayment ON T_Receipt.ReceiptNo = T_DepositPayment.receiptNo LEFT OUTER JOIN T_RentPayment ON T_Receipt.ReceiptNo = T_RentPayment.RentPaymentNo LEFT OUTER JOIN StandingOrder ON T_Receipt.ReceiptNo = StandingOrder.ReceiptNo LEFT OUTER JOIN T_TelephoneBills ON T_Receipt.ReceiptNo = T_TelephoneBills.ReceiptNo LEFT OUTER JOIN T_parkingBill ON T_Receipt.ReceiptNo = T_parkingBill.ReceiptNo LEFT OUTER JOIN T_OtherPayments ON T_Receipt.ReceiptNo = T_OtherPayments.ReceiptNo LEFT OUTER JOIN T_InvoicePayment ON T_Receipt.ReceiptNo = T_InvoicePayment.receiptNo LEFT OUTER JOIN T_cash ON T_Receipt.ReceiptNo = T_cash.ReceiptNo LEFT OUTER JOIN T_AdminPayment ON T_Receipt.ReceiptNo = T_AdminPayment.ReceiptNo LEFT OUTER JOIN T_BankTransfer ON T_Receipt.ReceiptNo = T_BankTransfer.receiptNo LEFT OUTER JOIN T_Utilities ON T_Receipt.ReceiptNo = T_Utilities.receiptNo LEFT OUTER JOIN T_credit ON T_Receipt.ReceiptNo = T_credit.ReceiptNo LEFT OUTER JOIN T_cheque ON T_Receipt.ReceiptNo = T_cheque.ReceiptNo LEFT OUTER JOIN T_InternetBilling ON T_Receipt.ReceiptNo = T_InternetBilling.ReceiptNo GROUP BY T_Receipt.Student, T_Receipt.ReceiptNo, T_cheque.Amount, T_credit.Amount, StandingOrder.Amount, T_BankTransfer.amount, T_cash.TotalAmount, T_AdminPayment.AmountPaid, T_InternetBilling.Total, T_Utilities.AmountPaid, T_InvoicePayment.amountPaid, T_OtherPayments.paymentAmount, T_parkingBill.paymentAmount, T_TelephoneBills.TelephoneCredit, T_Receipt.cancelled, T_Receipt.RemittanceReceiptNo, T_DepositPayment.[Deposit payment], T_RentPayment.AmountPayed, T_Receipt.Student HAVING (T_Receipt.Student LIKE N'06%')
Which gives a result of:
RecNo. 30429 Cheque 250 Deposit 250
30429 679.98 250
This is fine but when I do analysis on this it appears as though the student has paid two deposit payments. I was wondering with out querying each table independently from an application if there was a criteria to specify that I only get one deposit result. So as such say, give me all the payments but I only want one result from the other tables. I though about discrete but that wouldn't work here.
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)
I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?
Hello I am building a survey application. I have 8 questions. Textbox - Call reference Dropdownmenu - choose Support method Radio button lists - Customer satisfaction questions 1-5 Multiline textbox - other comments. I want to insert textbox, dropdown menu into a db table, then insert each question score into a score column with each question having an ID. I envisage to do this I will need an insert query for the textbox and dropdownlist and then an insert for each question based on ID and score. Please help me! Thanks Andrew
I need to be able to bulk insert a bunch of tables from their corresponding flat file. I have created an XML file (see below) which has the file name/table name pair at each node. I then created a ForEachLoop task and used the Node enumeration type and the following OuterXpathString: ReferenceFiles/File. At this point I get lost. How do I pass the 2 inside node values (file name and table name) to variables which I can then use as expressions for the bulk insert task inside the Foreach?
I used the data export wizard to export a single table to a single flat file (multiple wasn't allowed). I saved the package as a *.dtsx file which I'm attempting to edit to add the additional tables.
Creating additional sources is fairly easy copy of the first source and change to the table name.
I've tried copying the destination connection and changing to a new text file, but can't get past having to add each column manually to the new destination.
How can I duplicate the mapping that must be taking place in the wizard in the *.dtsx editing environment?
This seems like a simple / common task, but I've been unable to find a solution.
The method I wrote to delete records is working if there's one record, but not for more than one.

// Insert new parameter into command object DeleteCommand.Parameters.Add(DeletePrimaryKeyParam);
// Delete row, open connection, execute, close connection DeleteCommand.CommandText = ("Delete From Photo_TBL where PhotoID IN ('" + photoID + "')"); Trace.Warn(DeleteCommand.CommandText); // DeleteCommand.Connection.Close(); DeleteCommand.Connection.Open(); DeleteCommand.ExecuteNonQuery(); DeleteCommand.Connection.Close();

Hi, I am trying to build search engin with 11 parameters in 4 different tables in the database. For example: In search.aspx I have 11 textboxes namely nameTextbox, phoneTextbox, nationalityTextbox, ageTextbox etc. And in the result.aspx page I have gridview which post data from the database if the search match. I wrote this stored procedure. P.S please ignore the syntax. @name var(30),
@nationality (30),
@phone int,
etc
as
Select a.UserId, b.UserId, c.UserId FROM Table1 a, Table2 b, Table3 c
WHERE
name LIKE '%' @name '%'
OR nationality LIKE '%' @nationality '%'
OR phone LIKE '%' @phone '%'
etc
But I got an error when I am trying to execute this code because the nulls values so I wrote 1 @name var(30), 2 3 @nationality (30), 4 5 @phone int, 6 7 etc 8 9 as 10 11 12 13 Select a.UserId, b.UserId, c.UserId FROM Table1 a, Table2 b, Table3 c 14 15 WHERE 16 17 name LIKE '%' ISNULL(@name, '') '%' 18 19 OR nationality LIKE '%' ISNULL(@nationality,'') '%' 20 21 OR phone LIKE '%' ISNULL(@phone,'') '%' 22 23 etc 24 25
Also the error still exist. What is the best way to search for multiple parameters in multiple tables ?
Hello, I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services? Thanks
I have searched but not found quite the best way to look at this so far..
I have an application that outputs data to several text files (up to 30). These have commonality by an object name, but then contain completely different column data.
In DTS I had each of the source text file connections going to one OLE DB connection and then individual transform data tasks pointing to the one OLE DB connection.
Looking at SSIS, it would appear that I would need to have one source and one destination for each of these and therefore 30 parallel data flows?
Just wondering if there is a neater way of doing this??
It is a regular data import that happens a few times a day - the text files are named the same as the SQL tables - ie app_userdata.txt goes to app_userdata table.
Hello I am trying to delete multiple rows in my sql 2000 database, I have used the following sysntax but I keep getting errors: DELETE From NameList WHERE LName = 'Smith';and LName = 'Jones';and LName = 'Peters';and LName = 'Adams';and LName = 'Conner';and LName = 'Simon'; I have tried editing the syntax in a variety of ways, but I just can't find the correct solution. I have Googled and so far not found another syntax format. What am I doing wrong. Thanks. Lynn
I have a table with a large number of records that I need to delete, before attempt to perform the delete I also archived the records to another table.
So I need to delete all of these selected records stored in the archive table from the main table. I can now reference all the records that qualify for the delete in the main table by performing a join on the archive table like so:
select * from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
So all the records check out to be the ones I'd like to perform a delete on but I just can't figure out how to perform a delete of the records with little or no change to the existing query.
Obviously something like this won't work:
delete from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
Though it would be nice if it did.:D
So my question is how would I use the existing query with some modification to delete only the records that this query returns. I've tried selection of records in the main table based on the existing records in the archive table but it can return a higher number of records than what I know is expected. I actually need the join specified to be in place to do it.
