How Do I Check If The Trailer Row Is The Last Row?
Jun 5, 2007
Hello,
I need to import and validate a flat text file. The text file has a header and a trailer row. I have been able to implement everything except the following requirement:
I should check if the header row is the very first row of the file and if not, fail the import. I should also check if the trailer row is the very last row of the file and if not fail the import. The header and trailer rows themselves have a different format than the actual content rows and are not imported into the database, so I cannot do the check there.
I'm copying data out to a file with pipe delimiters. I would like toadd a header and trailer.Is this possible? If so, please help me with the steps.Also, is it possible to append to a text file while doing the bcp? Ifso, how?
I'm getting the above message when doing the nightly backup via a scheduled task. It's been working fine until this weekend when we ran out of disk space. I freed up space and still get this message when running manually.
I have an SSIS package which takes a SQL Query and generates a PIPE (|) delimited flat file. Simple enough. However, I also need to add a Trailer record at the bottom of the file (footer). To make this happen I could either do a UNION ALL on the same query script or what I've done is to create another query with the Trailer record and using the Merge component simply merged and appended the trailer record at the botton of the actual file.
The issue, however, is that the trailer record is always including extra PIPES at the end of the trailer. According to business, this wouldn't load properly at our vendor side due to the extra pipes in the trailer record as it'll be seen as additional columns.
Is there anyway to get rid of those extra pipes at the end of the trailer?
Trailer record should look like this:
TRAILER|A|B|C|D|
As of now, the appended Trailer record looks like this (additional pipes for each column in the main query script):

Hi I have two tables. one MasterDetail and second is countrydetail In master detail i have MasterDetailId (Primary) and countryId. In CountryDetail table I have Countrid (Primary),CountryName. I don't want to give relationship because i can insert null value in countryid in MasterDetail table. So i have wriiten query like this -> select c.CountryName,m.MasterDetailId from MasterDetail m,CountryDetail c where c.CountryId=m.CountryId and m.MasterDetailId= '2' If In MasterDetail table if CountryId is null then it will not show me any record.

How do I check when my database was last used ? I have two old databases that I think is not in use, but I want to check to make sure before I delete them or take them "offline".
Hi, I am developing a database for my company in SQL server 2000 and I have some few problems. Firstly.
I have a customers table and orders table in my DB:
Customers Orders --------- ------ CustID (primary key) ----------------< CustID . ^ ProductID . | Quantity . | . . | . etc. | etc. | relationship (one to many)
What I want to do is: 1) to be able to delete a Customer and automaticaly SQL server delete all the orders that this customer done from the Orders table. 2) If for some reason the CustomerID changes, SQL should be able to automaticaly update the necessary fields with the new values in the Orders table. Finally, 3) I want to be able to insert a new customer that has an order and update both the Customers table and Orders table automaticaly. e.g
CustID Name Address ProductID Quantity etc. ------ ---- ------- --------- -------- ---- 10-003 John London 33-25 2 ...
Such a kind of insert should add automaticaly the following entries in the two tables:
Customers Orders --------- ------ CustID (10-003) CustID (10-003) Name (John) ProductID (33-25) Address(London) Quantity (2) . . . . etc. etc.
A friend of mine told me that this can be done using Foreign Check constraints in SQL server. But I do not know what to do.
I have a DB with 4 tables in MSSQL6.5. In those tables write an NT service (4 threads for each table) 24h/day. I want to know somehow when i have no write in one of those tables for more than 1-2 hours (i dont want to querry those tables everytimes). MSSQL6.5 offer this kind of facilities? Or I can do this using stored procedures or something else?
I am Trying to add a check constraint that if the paymenttotal is 0 the column is allowed to have null and if its greater then 0 it is not allow to have null. Here is what I have so far but i get some syntax errors, See if you can see what im doing wrong and how to get this to be valid. Thanks heres what I got so far
Code:
ALTER TABLE Invoices WITH CHECK PaymentDate SMALLDATETIME NULL, CHECK (PaymentTotal = 0) PaymentDate SMALLDATETIME NOT NULL, CHECK (PaymentTotal > 0)
I also had this before i changed it to that and I got syntax erros as well but i dunno which is closer.
