我先需要写一点vb6的代码,其中有5个查询并且没个查询都赋值到ADODB.Recordset结果集中,数据库使用的是sql server

下面是一个示例代码,其中包含5个查询,并将结果集赋值给ADODB.Recordset:
```
Dim cnn As ADODB.Connection
Dim rs1 As ADODB.Recordset
Dim rs2 As ADODB.Recordset
Dim rs3 As ADODB.Recordset
Dim rs4 As ADODB.Recordset
Dim rs5 As ADODB.Recordset
Set cnn = New ADODB.Connection
cnn.ConnectionString = "Provider=SQLOLEDB;Data Source=MyServer;Initial Catalog=MyDatabase;User ID=MyUsername;Password=MyPassword;"
cnn.Open
Set rs1 = New ADODB.Recordset
rs1.Open "SELECT * FROM Table1", cnn
Set rs2 = New ADODB.Recordset
rs2.Open "SELECT * FROM Table2", cnn
Set rs3 = New ADODB.Recordset
rs3.Open "SELECT * FROM Table3", cnn
Set rs4 = New ADODB.Recordset
rs4.Open "SELECT * FROM Table4", cnn
Set rs5 = New ADODB.Recordset
rs5.Open "SELECT * FROM Table5", cnn
'使用rs1、rs2、rs3、rs4、rs5的数据
rs1.Close
rs2.Close
rs3.Close
rs4.Close
rs5.Close
cnn.Close
Set rs1 = Nothing
Set rs2 = Nothing
Set rs3 = Nothing
Set rs4 = Nothing
Set rs5 = Nothing
Set cnn = Nothing
```
在代码中,我们首先创建一个ADODB.Connection对象,并设置连接字符串,连接到SQL Server数据库。然后,我们分别创建五个ADODB.Recordset对象,并通过Open方法执行查询,将结果集赋值给这些对象。最后,我们可以使用这些结果集的数据。要注意的是,在使用完结果集后,我们需要关闭它们并释放对象。
