以下是 VB.NET 将 Excel 导入 MySQL 的示例代码:
Dim connString As String = "server=localhost;user=root;password=123456;database=test"
Dim conn As MySqlConnection = New MySqlConnection(connString)
Dim sqlCommand As MySqlCommand = New MySqlCommand()
Dim dataTable As DataTable = New DataTable()
'打开Excel文件
Dim excelConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:\ExcelData.xls;Extended Properties=Excel 8.0;"
Dim excelConnection As OleDbConnection = New OleDbConnection(excelConnectionString)
excelConnection.Open()
'读取Excel数据到DataTable中
Dim adapter As OleDbDataAdapter = New OleDbDataAdapter("SELECT * FROM [Sheet1$]", excelConnection)
adapter.Fill(dataTable)
'将数据导入到MySQL中
conn.Open()
For Each row As DataRow In dataTable.Rows
sqlCommand.CommandText = "INSERT INTO test_excel_data (Column1, Column2) VALUES ('" & row.Item(0) & "','" & row.Item(1) & "');"
sqlCommand.Connection = conn
sqlCommand.ExecuteNonQuery()
Next
conn.Close()
注意,在此示例代码中,Excel 文件位于"D:\ExcelData.xls",MySQL 数据库名称为"test",表名称为"test_excel_data",列名为"Column1"和"Column2"。您需要根据实际情况修改这些值。
另外,此示例代码仅作为参考,您需要根据实际情况进行适当的修改和优化。例如,如果您需要导入大量数据,可能需要考虑使用事务来提高效率和保证数据的完整性。
