use the bit datatype.
The only values for bit are 1 and 0.
To convert

case when bitfield = 1 then 'yes'<br />
else 'no end

In the DataGrid? An ASP.NET DataGrid? o a Windows Forms DataGrid? In any case, you can set a Format or FormatExpression property for the column (in your app, not in the database). Set the format to "D" to use the long date pattern. See here[^]

Help with dynamic sql

Hi all,
I am using dynamic sql in my stored procedure. There is a problem. There are parameters in the dynamic sql query which are of type int or rather which are not of string type. So it is giving me error saying cannot convert type string to int.
Can anyone help me out of this?

SQL 2005 Express?

Hello All,

I've downloaded and installed SQL 2005 Express a week ago. Now, I've downloaded the SQL 2005 Management Studio Express. It complains that it only works with SQL 2000 and SQL 2005. Am I stuck with sqlcmd.exe for creating databases in SQL 2005 Express?

Any help is appreciated.

So I've got it working now Smile | :)

I inserted three records into table Products(ProductID, ProductName) with ProductID set to AutoIncrement.
Three records with ProductID were 1, 2, 3.
After that i deleted three recored and insert the fourth record. This record would got the the productID's value is 4
How could i set the ProdudctID of this record to 1, just like the beginning.
Thanks

I’m guessing you’re using MS Access; the only way to re-start the counter is to compact / repair the database. It only works when there are no other data connections open and when no records exist in the table.

Hope this helps.

I'm making assumptions here it not very clear what you require

Run an update with two tables :
-------------------------------
update user_ref
SET user_ref.clientCode = Client.clientCode
from user_ref client
WHERE user_ref.USERID = Client.USERID

I have this:

With Me.daNumCourses.SelectCommand
.CommandText = "SELECT Section.Section_ID, Section.InstructorID, Instructor.ID FROM Section INNER JOIN Instructor ON Section.InstructorID = Instructor.ID AND Section.InstructorID = '" & Me.instr.ID & "'"
intCount = .ExecuteNonQuery()
End With
Me.dsNumCourses.Clear()
Me.daNumCourses.Fill(Me.dsNumCourses)
Me.txtNumberCourse.Text = intCount
I keep getting -1 so what am I doing wrong?

Thanks

Re: Count of Rows Returned

Colin Angus Mackay21-Nov-05 20:42

Why are you doing this? Why not just fill the data set and get a count of the rows in the DataTable? e.g. dsNumCourses.Tables[0].Rows.Count

I just want to get the count of the classes that a certain instructor teaches. I tried the .count property and that counts all of the rows in a particular table.

Thanks for your reply. If you have a suggestion on how to do that please post back.

Colin Angus Mackay21-Nov-05 22:45

Why don't you have your SQL as:

SELECT COUNT(*) FROM ....

Also, the way you build your SQL is suscepatable to a SQL Injection Attack and you should try and use parameterised queries where ever possible. You can read more on how to improve the security of your application here: SQL Injection attacks and tips on how to prevent them[^]

How do you return the number of rows from the query? In other words if I have a variable intCount how do I set intCount to the "count" of the query?

Thanks for your reply. We've noticed a few security holes in our application in a few places and we are fixing those right now.

Dim cmd As SqlCommand
cmd = SqlCommand.New()
cmd.CommandText = "SELECT COUNT(*) FROM MyTable WHERE someColumn=@someValue"
cmd.Connection = myConnection
Dim numRows As Int
numRows = cmd.ExecuteScalar()

numRows will contain the number of rows that match the given filter (i.e. what is filtered in the WHERE clause). COUNT() is an aggregate function that returns a count, when COUNT(*) is used it returns the number of rows. If you use COUNT(columnName) then it will count the number of rows where the column value is not null.

Does this help?

This is the correct way. ExecuteNonQuery should be used for Insert/Update/Delete statements. If the CommandText is "SELECT" statment, then it will always return -1. When it is DML statement, then it will return the number of rows affected by that DML statement.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
