Yes.
It won't do anything useful, in fact SQL will probably complain if you try to use it because you haven't provided any values - but as string concatenation, it's fine. Provided of course you have a table called "user1" - and I hope you haven't! :laugh:
The basic code you are looking for is:

VB

Using con As New SqlConnection(strConnect)
    con.Open()
    Using com As New SqlCommand("INSERT INTO myTable (myColumn1, myColumn2) VALUES (@C1, @C2)", con)
        com.Parameters.AddWithValue("@C1", myValueForColumn1)
        com.Parameters.AddWithValue("@C2", myValueForColumn2)
        com.ExecuteNonQuery()
    End Using
End Using

Solution 2

To insert a new row, you have to tell sql what table and columns you are adding data to. then, in the same order, you must list the values. An sql insert statement will look simmilar to this on.

SQL

INSERT INTO [Table1] (Column1,column2,column4) VALUES (1,'MickeyMouse',DECMBER/08/1986)
