I am new at ASP.net and I am having problems inserting data using C# in ASP.net
I have created a table named "Profile" in the MS sql server database named "MyDataBase". There is a field named "ID" that has data type 'uniqueidentifier'.
I am confused how to INSERT data into this data field. I have used MS Access and MYSQL in which there is an option of auto increment so we don't a unique identifier for each record.
Please tell me what can I do to If I want to have a uniqueidentifier for each new record I INSERT in the "Profile" table of MS sql server database.
While trying to insert, I get following errors
Cannot insert the value NULL into column 'ID'
and I don't know how I can insert something in this field that is of value type unique identifier.

I'm using the uniqueidentifier data type to generate a unique key for a table. Is there a way to change the type of unique key that's generated? I'd like it to start at 200,000 and increment as integers by 1.

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.
I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.
I hope someone can help me work through this.
Thanks in advance,

I don't know what I should try next, all of my tries have been without results in this case. I just wanted to create a temporary table, then insert one row into it and then use this row to compare if this row exists in another table or not. This is my script: ------------------------ CREATE PROCEDURE imp_Tippimport (@TGName char(33)) AS
BEGIN
CREATE TABLE #tTippgeber ( TGName2 char(33) )
INSERT INTO #tTippgeber (TGName2) VALUES (@TGName) *** see below ***
IF NOT exists (select TGName FROM Tippgeber WHERE TGName = @TGName)
INSERT INTO Tippgeber SELECT TGName2 FROM #tTippgeber /* SELECT * INTO Tippgeber FROM #tTippgeber */
ELSE
UPDATE Tippgeber SET TGName = t.TGName2 FROM #tTippgeber AS t, Tippgeber WHERE TGName = t.TGName2
END GO
I also created a cursor and used a fetch in to a veriable in the line with the stars to see the value of TGName2 but it was NULL.

I need a sql server 7 script that will migrate data from my DEV dbase to my WEB dbase. The data desired is for the field rig_id for rig number 0018. The shell of both dbases are similar. The table is called rig. An snapshot is below:
The rig table also exists on the WEB dbase. However, the Kaila data for rig_id number 0018 needs to be added to the WEB dbase's rig table. The Williams, Borsha, and Yoida data already exists on both tables.
I need to perform this migration w/ a TRANSACT-SQL stored procedure.

Hi, I want to store a time duration such as 1:30 (mm:ss), 1:00, or 1:23 in a SQL 2005 database. What is the best data field type for this data? DateTime or TimeStamp? Thanks
I am using SQL Server 2005 Express. I am creating a table, which will have a comments field. Whats an appropriate data type that should be used for a "comments" field? So far, I have unlimited text and characters can be entered, but that a limitation can be placed.
I'm using XmlDataSource to build reports based on WebService output (as plain XML text). (SSRS2005)
I have several fields which contain Float/Decimal/Integer value, but RS reads them as text and I have to use CDbl() to convert text to numeric value. In MSDN I found some info about "Type" attribute(?) for XmlElement. My xml is: ...<Field1 Type="Float">34567.89</Field1>...
But RS still reads data from this field as text.
Is there any way to specify field's (xmlelement's) data type instead of using CDbl() function everywhere?
Another table with an uniqueidentifier which references the user iD
I want to set the value of the iD in one of the entries in the second table to null.
I tried this: string assigned is null, i am passing this as a method parameter ............... string queryString = "UPDATE [table2] SET AssignedUserId=@assigned WHERE ProblemId = @id"; System.Data.IDbCommand dbCommand = new System.Data.SqlClient.SqlCommand(); ................... System.Data.IDataParameter dbParam_au_pr = new System.Data.SqlClient.SqlParameter(); dbParam_au_pr.ParameterName = "@assigned"; if (assigned == null) { dbParam_au_pr.Value = null; } else { dbParam_au_pr.Value = assigned; } dbParam_au_pr.DbType = System.Data.DbType.String ; dbCommand.Parameters.Add(dbParam_au_pr);
I also tried using "" instead of null, or not using that "if" statement at all. I get an error that says:
Parameterized Query '(@id nvarchar(1),@assigned nvarchar(4000))UPDATE [tracker_Probl' expects parameter @assigned, which was not supplied. Please help with this as soon as possible.Thanks

Hi I am currently working on an application that uses a stored procedure to retrieve data from a database and then display it in a web page. My problem is that some of the data in the database will be images, I am currently putting in test data to test my code/procedures my problem is how do I put in test data for images, when I am finished I am going to add an admin section that will allow me to add images that way but how do I go about adding them to the database until then? I have set the field to the image data type but have no idea how to relate this to an image on my server? Thanks, Adam
Hi there! I'm using a Switch statement in my SQL as follows:
Code:
SELECT symbol, Switch(timestamp Is Null,Null, timestamp <= 005959, 0, timestamp<=235959,23) AS period INTO averageprice FROM stocktrades;
Now here's my problem. The Data Type stored in the 'period' field of this new table I've created, dubbed averageprice, is a Text field and I want it to be a Number field. I've tried my best to figure this out and I'm still looking so any helpful hints or solution would be greatly appreciated. Thanks!!!
In my database there is a text field type that is used to enter streetaddress. This address could be a few lines long, each line with acarriage return at the end.Is there a way to search for these carriage returns and break out whatis in each line seperately?Thanks.Mike
OK, I use asp.net membership and have created a new table that links together related users by use of the uniqueidentifier field as a foreign key. However, it is possible to link to a not-yet existent user (by their email) so that when that user creates an account and gets a guid, it will be updated into my table of related users and finalise the link. Trouble is, I'm trying to stop people adding the same "pending user" multiple times, so in my BLL logic I look for the entered email address for the current user and I want to check on the foreign key (the GUID field) so that I can tell the user that they've already added this user, but they haven't signed up yet (if they haven't got a foreign user key with a guid in it, they haven't signed up yet). However, when I check the foreign key guid value (shows as null in sql enterprise manager) for null values, it never goes down the "true" logic channel... what I mean is that I've debugged it, hovered over the item I've read (it says it is system.dbnull, which it is) and yet when I do "isDBNull(myGUID.Value)" it never equates to true! Why not?
AnupG writes "hi, the most common feature that any RDBMS provides should be that if we want to store the data in the MSSQL tables then the data should be presented in masked/formatted like for eg.the password text in field should be like "*****". I am using SQL 2000 but i unofrtunately i couldn't find any such feature in defining the data type in SQL server 2000 ...?"
