在VBA中,编写Excel与数据库的连接字符串取决于你要连接的数据库类型。以下是一些常见数据库类型的连接字符串示例和编写方法: 1. 连接Access数据库 对于Access数据库,连接字符串通常比较简单,因为Excel和Access都是Microsoft Office的一部分。 vba Dim conn As Object Set conn = CreateObject("ADODB.Connection") conn...
Setcnn=CreateObject("ADODB.Connection") Setrst=CreateObject("ADODB.Recordset") 前期绑定:先引用“Microsoft ActiveX Data Objects 2.x Library”(尽量选择高版本),然后直接就可以使用了。下面两种写法都可以: Dimcnn1AsADODB.Connection Setcnn1=NewADODB.Connection Dimcnn2AsNewADODB.Connection 前期绑定能更好的...

在按照上述步骤配置了环境支持后,就可以在VBA中使用代码连接SQL Server了。 首先需定义连接对象: Dim conn as ADODB.Connection Set conn = new ADODB.Connection 这里也可以简写为: Dim con As New ADODB.Connection 连接数据库 conn.ConnectionString = "Provider=SQLOLEDB;Server=192.168.1.1;Database=XXXXX;Uid...
