Error updating data set

[Guest]

Hi,

I'm new to '.net'. I'm working in vb.net and have an error don't know the cause of or how I should go about debugging it.

Here is the code:

Dim dsNwind As New DataSet
Dim daProds As New SqlDataAdapter(cmdSelProds)

daProds.Fill(dsNwind, "Prods")

Dim drProd As DataRow
drProd = dsNwind.Tables("Prods").NewRow

drProd.Item("ProductId") = 1006
drProd.Item("Name") = "widget"
drProd.Item("Grams") = "11g"
drProd.Item("Percent") = 5

dsNwind.Tables("Prods").Rows.Add(drProd)

daProds.Update(dsNwind, "Prods")

The last line of code produces the error:

"Incorrect syntax near the keyword 'Percent'."

I tried commenting out the line :

drProd.Item("Percent") = 5

but still got the same error.

Any help is appreciated.
Thanks,
Phil

Hi Phil,

That is mostly with sql words try it everywhere with [Percent]

I hope this helps,

first of all, the syntax error is in the INSERT statement in the
DataAdapter. Since you didn't use a CommandBuilder, I don't see where
that statement came from.

Hi Cor,
Thanks for the response.That doesn't seem to be the problem.

I changed the code to use the square brackets and take the percent out and still got the same error in the same spot.
This is the updated code:


Dim cmdSelProds As New SqlCommand("select ProductId, Name,Grams,[Percent] as pr" & _
" from ProductDetails", cnNwind)
Dim dsNwind As New DataSet
Dim daProds As New SqlDataAdapter(cmdSelProds)

Try

daProds.Fill(dsNwind, "Prods")

Dim drProd As DataRow
drProd = dsNwind.Tables("Prods").NewRow

drProd.Item("ProductId") = 1006
drProd.Item("Name") = "widget"
drProd.Item("Grams") = "11g"
''''''drProd.Item("Percent") = 5
drProd.Item("pr") = 5

dsNwind.Tables("Prods").Rows.Add(drProd)

Dim cbProd As New SqlCommandBuilder(daProds)

daProds.Update(dsNwind, "Prods")

I still get the same error at the same line (the last line) :

"Incorrect syntax near the keyword 'Percent'."

Hi Phil,

I could not see that in the previous message, however I do not know a table
in northwind with the name ProductDetails, did you made that yourself or
where is my mistake?

Mostly when you search on ProductDetails and northwind on MSDN you will get
a hit, however I get nothing.

Hi Cor,

What happened is I'm working through an exercise in a text that uses Northwind as a database, but since I don't have Northwind, I'm using one called db_grocertogo (which has a table productDetails). I've got northwind in my code though because I didn't bother changing the names of the variables I'm using.

Regards,
Phil

Hi Phil,

Forget my last message, what happens when you take that percent completly
out of your code, only to try?
