I receive data in .csv format. I have a some records on a table, so what I need to do is to check if the data I receive exist on the table of records that I need to match against.
If the record exist, then an email/sms should be sent to notify me that the records has been matched and then that record should be flaged that it has been tested so that I don't test it again as the incoming data are saved.
CDC or Change data capture is a new feature in SQL Server 2008, which is an ability to record changes to table data into another table without writing triggers or some other mechanism, Change data capture records the changes like insert, update, and delete to a table in SQL server.I have sql 2005 and I have created triggers and tables CDC to capture the data. everything functions good and the data is being updated in the _CDC tables. all i need to do now is to generate the updated data as a report (excel/html)- what should I do ......?i need to show only the updated columns when user selects the date periods ( Range between dates ) and the person name - i need to display any updated info about that person during that period. So this updated columns about this person should be displayed in excel formatted column wise.
When processing many records starting from 10,000 System.OutOfMemoryExceptio get the error. There would be some way to handle this type of memory error ?.

currently I am doing a web application project using 3-tier formating to do out the project. In the grid view is displayed with data retrieved from the database and at the footer there is a row of empty fields for the user to insert records into database and when user clicks on Add New, a new row of empty fields will be populated below.
The database.cs and stored procedure is used to stored the data into the database.

This is the stored procedure code:

I am not sure of how to code out for the business logic?
I code this in business logic but its wrong as the error states the Insert method could not be found:
Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?
Name Product section of job Quantity Max Quantity A ABC offset print 100 1000 B ABC water base 200 1000 C ABC offset print 950 1000
How to insert multiple records like above at once, and how to manage quantity user input is not over max quantity. In example above: Max quantity of Offset printing is 1000 (bind from database, visible=false)
Woker A does Offset printing with quantity 100, C does Offset printing also but with quantity 950, if we sum quantity A and C do will be over 1000 Ã message box: warning
I am using link button in updatepanel and click on asp:linkbutton it refereshes all page. to stop _dopostback on link button click.or any alternative to use linkbutton.
I've been wracking my brains for a while. I have a master record that I want to add children to. In a database it's a one to many relationship with a foreign key in the child table.
I have a formview that I want to use to fill in all the master record info, and choose the child info from a dropdownlist, and click an add button, and have the add button add the child info to some control on a page. Then when the user clicks insert, the formview has an ItemInserting EventHandler that will handle all the logic for inserting the master, grabbing its primary Key.
So, I know what to do, I'm just not sure of what control to use, or what memory object etc., that I want to store the child info in until the master record gets created.
I'm sure this has been done a million times, but for all my searching, I couldn't find anything to help me. Does anybody have some advice or can anybody point me to an internet resource where this has been hashed out?
Is it ok to do multiple records update with the following requirements and be safe that the operation will not get timed out? A user requiring me to do the following using a web form:
I. Display a list of accounts in a GridView for multiple records insertion with no client side validation. Each account will accept new reading and posted date values.
II. Once the user presses the submit button, the following steps will be performed for each record at server side:
1. Check if new input data is for new or old period. A checkbox is to be selected in the form. 2. Check if new data has existing related records. Else this is first time insertion; get consumption result and save to db. 3. If records found, get previous reading and date. 4. Check if new reading and date is greater than previous reading/date else should inform the user. 5. Get new consumption = new reading - previous reading and some other operation. 6. A join select statement will be used to get the lowest and highest values (consumption) for current account. 7. Compare the new consumption result with previous consumption to give a status indication for new reading as either high, low or normal to be saved into the db. (# 6 values will be used here) 8. If everything goes ok, save new data into 3 different tables. 9. Display the GridView with new data.
The SQL server and the hosted page are in two different servers.
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.
I have a web project with more than 100 input boxes , so in every INSERT and UPDATE to sql server in front of sql statement I must put the golden N word, so it will be in UNICODE mode. Do we have some alternative of this? How can i make it in EVERY UPDATE and INSERT to sql server in data layer level- make it like u insert UNICODE (without N word) How can you get MSSQL server to accept Unicode data by default into a VARCHAR or NVARCHAR column?
I know that you can do it by placing a N in front of the string to be placed in the field but to by quite honest this seems a bit archaic in 2008 and particuarily with using SQL Server 2005. Example:
cmd = New SqlCommand(sql, ConnectionFromEnum(whichDatabase)) cmd.Connection.Open() i = cmd.ExecuteNonQuery()
so....
the question is : Am I suppose to make something with SQLCOMMAND to set- "enter evthng like it is UNICODE, with N auto"? or i must specify UNICODE by default in somewhere else? just to indicate that i already set in web.config
So global questions HOW TO MAKE INSERT AND UPDATE Unicode by default in every insert and update methods, without placing N word in front of literal string?
