For example: INSERT INTO table (col1, col2, col3) VALUES ('value1','value2,'value3')But I would only like to insert the row if value3 isnt already present in col3 in some previous row. What is the best way to do that?And the insert command is run 50+ times in a loop (with different values each time for value3)
View 4 RepliesI'm using Visual Web Developer Express 2008 and SQL Management Studio Express 2005. I need to link 2 tables to either present in a Master/Detail or GridView/Form view.The goal is to allow the user to view time card information from the AS400 (read only) and then enter any corrections into a SQL table. My problem is in trying to connect the two tables.I've asked the AS400 administrator to add a unique identifier field to the table (HAPOINT), but he says he can't. I've tried to concatenate a field within Visual Web Developer's Query Builder but keep getting errors.Table 1 - exists in AS400, is non-permanent (cleared every 3 months) and can't be modifiedEmpl ID WO Date In Time In Date Out Time Out Table 2 - exists in SQL Server, newly created for this project (no data yet, so can be modified)Rev ID Empl ID Date (of revision entry) X (Revise - y/n) Revised Time In Revised Time Out I tried finding a solution through the SQL Forum, but haven't gotten a solution, so I'm posting here. There are additional details at that post:http://forums.asp.net/p/1516929/3658517.aspx#3658517Can anyone tell me how to concatenate "Empl ID /WO / Date In / Time In" from Table 1 to produce a unique identifier that I can then use in Table 2, thus providing the link between the two tables? Or, is there another way?
View 8 RepliesI am generating a unique Ref number using this sql statement: SELECT REPLACE(STR(CAST(CAST(NEWID() AS binary(5)) AS bigint),12),0,0) as REF Subsequently, I need to insert this REF into sql database table in stored procedure. Here is what I did in my stored procedure:

I have a insert into statement thats inserting my numbers from a numeric text box on my aspx page. I am choosing the Amount Type then putting in a a number.
So i have a drop down that i select example Direct Charge then i enter 600.00 and click add it puts that in to the databse for me woot..
I then put in say Misc Credit and enter 200.00 it inserts in that into the database woot.
The look up table that has my amount types has a field called numeric opperator which is either + or - the Credit being a - and the Charge being a + then my stored procedure takes all my + numbers and adds them up and subtracts all the - numbers.
I want to change that so that it actuall be inserted into the table as a - number form the start. So I want choose Misc Credit enter 200.00 and click add then my event says o yea thats a credit insert 200.00 as -200.00

View 9 RepliesI am returning a dataset from a method and trying to set one of the columns as Primary Key.
CategoryList.Tables[0].PrimaryKey = new DataColumn[] { CategoryList.Tables[0].Columns["CategoryNodeId"] };
Interestingly it gives me this error at run-time, These columns don't currently have unique values.
Now I perfectly know why this error should error, but there are no duplicate keys in this data column. I broke the code in between and bound the dataset to gridview to check if this column contains any duplicates and this is not the case. Here is the result set underneath. Have a look at the first column 'CategoryNodeId'.

View 4 RepliesI currently designed a school result portal. If the students want to view their result, they input their student school number in a text box to search out their result. But this is not secured because anybody can look up any students result if you have the number which is even written on their school uniform for identification.
I have being trying to secure this result by trying to generate or code special numbers that the students will input with their school number. The special numbers will be random numbers and may be from 10 and above, it might even contain letters. How do
I code this. I believe this is the best asp.net forum. I want the students to be inputing this special unique numbers and their student numbers so that there result will be avaliable to them.
I have an SQL database table like the following:
ID // Code // Shape
The ID is the integer identifier.
On one line the Code may be OX01 and shape Hexagon for example
Then the next line the code is still OX01 but the shape is Triangle.
What I want to do is be able to pull back data for every line that is equal to a unique Code column. in the above example OX01 Hexagon would be returned but not OX01 Triangle.
I've tried using SELECT DISTINCT but it brings back all records and doesn't filter them correctly.
I've considered having another column which could have Child/Parent data so that only the parent is returned but i'm sure there must be a better way of doing this.
I have a datatable and I want to have a view on it with unique dates. The thing is that I want the date to be unique if the year,month and day are the same, I dont care for the exact time.
I now have:
Dim dtUniqueDates As System.Data.DataTable
dtUniqueDates = dt.DefaultView.ToTable(True, "updatedate")
So in this case 12 february 2011 13:54 is different from 12 february 2011 15:54. But since year,month and day are the same I want them to be unique.
I wanna join all the field as a new col.
but how can i ignore the empty field because i always join the field and separate by space like the following.

how can i ensure all the space is one space only.

I have a 20 to 30 fields on a form. Most of them are optional. However, the users can fill out what they want. If a user dosen't fill in a field when data is sent to the database it's sent as blank, instead of NULL. Is there a way I can generically say "for all textboxes if Equals("") then DBNull.Value". Without going through each and every textbox?
