Unable to create a table & insert values in the database

The below code is suppose to create a database and a table with a column "FirstName" which is assigned a value "James"

Imports System.Data.SQLite
Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        SQLiteConnection.CreateFile("c:\mydatabasefile.db3")
        Dim sqlConnection As New SQLite.SQLiteConnection()
        Dim sqlCommand As New SQLiteCommand

        sqlConnection.ConnectionString = "Data Source=c:\mydatabasefile.db3"
        sqlConnection.Open()
        sqlCommand.CommandText = "CREATE TABLE MyTable(EmpID INTEGER PRIMARY KEY ASC,  FirstName VARCHAR(25));"
        sqlCommand.CommandText = "INSERT INTO MyTable(FirstName) VALUES('James');"
        sqlConnection.Close()
    End Sub
End Class开发者_JS百科

But for some reason the app only creates a a database which has a size of 0 bytes. Why is it not working . I am using I am using SQLite ADO.NET Provider. , VS 2010, Winforms

You are never executing the sql commands

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        SQLiteConnection.CreateFile("c:\mydatabasefile.db3")
        Dim sqlConnection As New SQLite.SQLiteConnection()
        Dim sqlCommand As New SQLiteCommand("", sqlConnection)

        sqlConnection.ConnectionString = "Data Source=c:\mydatabasefile.db3"
        sqlConnection.Open()
        sqlCommand.CommandText = "CREATE TABLE MyTable(EmpID INTEGER PRIMARY KEY ASC,  FirstName VARCHAR(25));"
        sqlCommand.ExecuteNonQuery()
        sqlCommand.CommandText = "INSERT INTO MyTable(FirstName) VALUES('James');"
        sqlCommand.ExecuteNonQuery()
        sqlConnection.Close()
    End Sub


End Class

You also need to be setting the Commands Connection which you can also do by saying

sqlCommand.Connection = sqlConnection That should fix you up

You never execute the sqlCommands. You should use .ExecuteNonQuery() to get something into the database, otherwise nothing will be done.

Also let the command know what connection to use. sqlCommand.Connection = sqlConnection
