I'm developing a website which requires the user to insert 252 units of data into 252 columns in a SQL table.
I have the following question which I hope anyone here could answer or maybe give me some comment:
Is it going to take a very long time to insert the data after the button is clicked?
How can i make this process faster?
I have to insert a multiple records under the single table.So i have to execute the command in the frontend for every records.
Inorder to avoid i write the query like this
insert into table1(field1,field2) values('1','Test1'),('2','Test2');
and also i tried
insert into table1(field1,field2)
SELECT "1","Test1"
Union all
SELECT "2","Test2"
But I am getting syntax error.

View 2 RepliesI have a question which is insert multiple rows in a single insert? Is that possible?
For example:
INSERT INTO EMPLOYEE(NAME, AGE)
VALUES
(JAN, 18),
(JEN, 20),
(JIN, 23)
Using C#
I have code, something like I ask but there's an error.
Here's the code
string sql = "INSERT INTO EMPLOYEE(NAME, AGE) VALUES";
for(int i = 0; i < data.length; i++)
{
sql += "(@name" + i.ToString() ", @age" + i.ToString() + "),"
}
sql = sql.Remove(sql.Length - 1);
cmd = SqlCommand(sql, con);
cmd.ExecuteNonQuery;
I got an error of "Fatal error encountered during command execution."
The error goes here
{"Parameter '@name0' must be defined."}
I have a grid with three columns, two of which contain drop-downs, all of them getting filled from a web service result set. Now I want to allow the functionality of adding a new record in the grid by clicking an Add button present outside the gridview.
Whenever the user clicks the Add button, a new record should be created in the grid with value list filled in the drop-downs with the available options.
What is the best possible way to achieve this considering extensibility in mind.
I have got a page in which there is a file upload option where I have to upload/import the csv file. What I want to do is to check if the correct format of file is uploaded for instance if any other than csv file is uploaded, the system should give an error message. Also what I need to do is to check certain fields of the csv file for instance there are some mandatory fields in the csv file which should be there like name , postcode, How can I check that these fields are not empty . After performing these task, the system should automatically upload the csv file onto the sql sever 2008.

View 5 RepliesIf I create a data tabe in C# like so:
datatable t = new DataTable;
DataColum C1 = new DataColum;//ID column
t.Columns.Add(C1);
//the same with column C2
Then I fill up the table with some data. Then the goal is to either insert this data or update data in an SQLtable in SQL. If the data is inserted, the ID column in t would be empty, if updated, it would not be. So in the insertion case, the sql query needs to make sure that unique IDs are assigned during insertion, in the update case, it just has to look for the right IDs.How to go about this? Asking because I am only familiar with updating and inserting single lines into a table. One could loop in C# over the datatable t of course and insert or update line by line, but this would probably be slow. Is there a way to write an SQL query like this somehow:
Insert Into SQLTable Values (@t)
?
And Update like this:
Update SQLTable SET ... Where C1 = @t.C1
Or something like that.
I know that SQL server can create automatic update and insert queries and that you can then type things in C# like
Adapter.Update(t);
But, this has proven to be super slow on our server, for unknown reasons. I have asked on this forum and got some answers from experts, but was not able to srot out the problem. How can we write a custom SQL query that allow updating and inserting a whole table, instead of just one line at a time?
i have used a button in gridview.i want after a single click all the button become disable..
View 9 RepliesI have a webform page that has a formview, gridview and two sqldatasources. The formview has many fields and an edit button. When a user attempts to edit the formview i want to create a seperate log record that contains datetime, username, and couple other fields from the formview. I want this log record to appear below the formview in a simple gridview. I know theoretically i can create a sql trigger but dont know how to pass the data into it. So i believe the logic is to have c# do it in the code behind during "itemUpdating" except i am struggling with stringing the values from the formview and using them in the sql insert statement, not to mention i am a asp.net newbie! i created this sql statement in itemUpdating, but this as far as my experience can take me.

I'm having some problems with the interface I've created. I am getting value and ids in a string using for loop on the controls(objects). After some searching, I've discovered that it isinserting an empty string into my database fields as opposed
to an null value. I need my application to insert NULL values, not emptry strings. Can any one suggest me on this and also how can i prevent sql injection on the above code. because i am passing like following :
@variable1='Name,Address,Remarks' //(as a Column name)
@variable2='Pritesh,Mumbai,any remark' //(as a column value for above.)
exec myprocedure 'tablename','@variable1','@variable2'.
if any one pass single inverted comma in the above column value in @variable2. my code give me error. how can i prevent this sql injections..
