I have one excel sheet from which I am getting data in dataset using OleDbConnection
private static DataSet ImportExcel(string FileName, bool hasHeaders)
{
string HDR = hasHeaders ? "Yes" : "No";
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + FileName +
";Extended Properties=\"Excel 8.0;HDR=" + HDR + ";IMEX=1\"";
DataSet output = new DataSet();
using (OleDbConnection conn = new OleDbConnection(strConn))
{
conn.Open();
DataTable dt = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
foreach (DataRow row in dt.Rows)
{
string sheet = row["TABLE_NAME"].ToString();
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [" + sheet + "]", conn);
cmd.CommandType = CommandType.Text;
DataTable outputTable = new DataTable(sheet);
output.Tables.Add(outputTable);
new OleDbDataAdapter(cmd).Fill(outputTable);
}
}
return output;
}
Now I want to Insert data from this dataset to sqlite table.
This is how we can do it
SQLiteConnection m_dbConnection;
void createDbAndTable()
{
SQLiteConnection.CreateFile("MyDatabase.sqlite");
m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite; Version=3;");
m_dbConnection.Open();
string sql = "create table myValues (name varchar(20), highScore int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
}
void fillTable(DataSet ds)
{
var dt = ds.Tables[0];
foreach (DataRow dr in dt.Rows)
{
var name = dr["name"].ToString();
var score = Convert.ToInt32(dr["value"].ToString());
string sql = "insert into myValues (name, highScore) values ( '" + name + "'," + score + ")";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
}
m_dbConnection.Close();
}
