SQL Server :: Can't Delete 3 Rows In 3 Tables...
Sep 29, 2010
I am having trouble deleting three table rows using SQL. The middle table is a junctional table allowing a one to many relationship between table 1 and table 3.
Table 1
Order_Id int Primkey FK1
Name Varchar
Date Datetime
Table 2
Order_Id int PrmKey FK1
Item_Id int PrimKey FK2
Table 3
Item_Id int PrimKey FK2
Description Varchar
Price money
Acually, I want to delete all rows associated with any particular order.

I am accessing rows in an SQL database table based upon the contents of the Primary key and another column. But, I cannot insert new rows in the table when the content of the new Primary key column already exists in another row. Can I define the table with a multiple column Primary key so that a unique value can be based upon the content of both columns?

I am accessing rows in an SQL database table based upon the contents of 2 Primary key columns. But, I cannot insert new rows in the table when the content in one of the new Primary key columns already exists in another row. I get an error message that says: "Violation of PRIMARY KEY constraint 'PK_ReferendumVoters'. Cannot insert duplicate key in object 'dbo.ReferendumVoters'. The statement has been terminated."
The reason why this error is occurring is because I first stored "Referendum 1" in one column along with "me" in the second column of a new row for a "ReferendumVoters" table. Then, I attempted to insert a new row with the same "Referendum 1" string in the first column along with a different name in the second column. But, it will not let me do this even though I created a new index that defines the two columns as unique. Is there any way that will enable me to do this?

I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List??
WHich one is better, I mean ObjectDataSource or SQLDataSource or my XML method?
My XML will be like this
<root>
<Customer>
<CustomerID>GUID1</CustomerID>
<CustomerID>GUID2</CustomerID>
<CustomerID>GUID3</CustomerID>.....

I have a problem where I would like to get a comma-separated list of items from a couple of tables as part of a set of results. All the searching I've done so far has produced results for dealing with one or two tables. I have four, and can't get my head around how to adapt the sql to deal with it.
I have the following layout:
*Table_Castings*
+---- CastingID {PK}
| MouldID
| SerialNo
| CastRef
| MeltCode
| Signature
|
|
| *Table_CastCertificates* *Table_Certificates*
| CertificateID {PK} ----------- CertificateID {PK}
+---- CastingID {PK} Description
FileID -----------------+
|
|
*Table_CertificateFiles* |
FileID {PK} -------------+
FullLocation
The results I would like include the following columns:
CastingID, MouldID, SerialNo, CastRef, MeltCode, [Certificates],
Where Certificates is a comma separated list of Description + " " + FullLocation records. (What I'll actually do is add http:// and other html codes to make FullLocation a hyperlink, but I can do that.)
Some SQL I've already got is this:
DECLARE @str VARCHAR(500)
SELECT @str = COALESCE(@str + ', ','') + '<a href="http://' + Table_CertificateFiles.FullLocation + '">' + Table_Certificates.Description + '</a>'
FROM Table_CastCertificates INNER JOIN
Table_Certificates ON Table_CastCertificates.CertificateID = Table_Certificates.CertificateID INNER JOIN
Table_CertificateFiles ON Table_CastCertificates.FileID = Table_CertificateFiles.FileID
WHERE (CastingID = 45)
SELECT output = @str
This actually gives all records in the for the specific casting, but I keep getting an error at the "=" in @str = COALESCE when I try joining it to another query to get each casting.

I have 5 tables as follows
as it can be seen from diagram, I have one table ie.patientdetails with Pid as primary key and other 4 tables have pid which is foreign key related to Pid in patient details.
the problem is that when if a test data is filled for say patient with Pid as 1, the data is saved nicely in required tables
If i try doing that again for same patient then a duplicate is created in test tables with pid as 1.

Im having a go at doing a report for my asp.net application. I have 2 tables, one which lists a loan we have given to a customer, and another table which lists repayments against the loans.
I want to display each loan and how much is outstanding against it. My problem is that each loan is repeated in the table for each repayment against it. So when i try to sum up the loans awarded to a customer, if they only have one loan and have made 3 repayments against it, it sums up the amount awarded against each record.
eg, if i award a customer a loan of £200, and they make 3 repayments of £50, 3 records appear in the table. The amount awarded is repeated against each repayment, and when i total a customers loan amounts, it totals 3 x £200.
I have put the details into the grouping row, where it is grouped by loan_id, displaying the toal of repayments instead of each repayment. This stops it repeating in the table, but when i total the amount awarded field it still calculates 3 x £200.
I tried calculating the total on the report item after grouping but you cannot calculate on a report item.
Is there a way to stop the table from repeating the amount awarded against each repayment? Or even a way in the SQL statement of the dataset to make it display a total of repayments rather than each repayment. Cant see how to calculate a total repaid as i would need to pass a Loan_id in as a parameter.

Maybe this could be a simple questino, but for me it's difficult to do this action: I have a table in sql server 2005 with some records stored, for example 10 records. The primary key of this table, let's call it "Employee", it's a number field with an autoincrement constraint. I want to store more data into the table by using a OdbcDataTable object and OdbcDataAdapter and adding new rows to the datatable and afeter that use the "Update" method from the OdbcDataAdapter object.
The big deal is this: let's suppose that I want a add a new record to the datatable object, using any method or code sequence that you want. if I have 10 records stored on the data base table, when I retrieve this table schema by using the OdbcDataAdapter "Fill" method, I have a copy of the data base table schema in the DataTable object, right?. if I add a new row on the datatable object, it's suppose that the primary key column of that table must AUTO-INCREMENT the value of the key, I mean if the last value that I store on the table was the number 10 on the PK field, when I add a new row on the datatable object, the PK value on the datatable object must be the number 11 if the autoincrement constraint is present into the DataTable object, but in my case, it doesn't work
So, How can I define the conditions or set the c# data objects properties to wor in that way???. In this moment the PK column on the odbcDataTable doesn't auto-increment its value when I add a new row on it.
Please helpe with this.
PD: I have another question about the DataTable object, how many records can store this object?? I have some problems with this because sometimes when I use the Fill() method to get data into the DataTable or a DataSet object there's no problem if the Fill() method retrieves about 142000 records, but when I retrieve over the 145000 records, when I inspect the DataSet or DataTable object by using the debuging mode, they have null value. Any of you can tell me why this situation ocurrs??

I've created a membership system based on asp.net 2. There are other tables that store user information, such as emails sent etc. I've created a users table based on the TableProfileProvider. My question is concerning deleting the member
Is it OK to delete the member from the aspnet_membership table and roles related tables using Membership.DeleteUser, though keep all the custom tables and the information including the information in the Users table created by the TableProfileProvider? or can you foresee problems?
