如何判断vba数据库是否连接成功

1、首先需要先在VBA中启动数据库连接支持，按下Alt+F11打开VBA，在菜单栏选择“工具”到“引用”。

2、其次在d出的引用窗口中，找到MicrosoftActiveXDataObjects6.1Library和MicrosoftActiveXDataObjectsRecordset2.8Library。

3、最后把前面的框勾选上，点击确定即vba数据库连接成功。

Microsoft Office Access是由微软发布的关系数据库管理系统。它结合了 MicrosoftJet Database Engine 和 图形用户界面两项特点，是 Microsoft Office 的系统程序之一。用vba代码将access数据库连接求代码，代码如下：

Sub FYMXDL()

Dim XQID As Integer

Dim JZID As Integer

Dim FYID As Integer

Dim FBXZ As String '分包性质

Dim DW As String

Dim SARR(1 To 31) As Double

Dim rst As New ADODB.Recordset

mYpath = ThisWorkbook.Path &"\jzfydata.accdb"

Set cONn = CreateObject("ADODB.Connection")

cONn.ConnectionString = "Provider=Microsoft.Ace.OleDB.12.0Data Source=" &mYpath

cONn.ConnectionString = cONn.ConnectionString &"Jet OLEDB:Database "

cONn.Open

XQID = Cells(3, 2).Value

JZID = Cells(3, 5).Value

'清空改小区-建筑的费用明细

Sql = "delete  from fymxb where 小区ID=" &XQID &" AND 建筑ID = " &JZID

cONn.Execute Sql

Const kshh = 7

hh = kshh

Do While Cells(hh, 3).Value >0

FYID = Cells(hh, 3).Value

FBXZ = Cells(hh, 11).Text

For i = 1 To 31

SARR(i) = Round(Cells(hh, 13 + i - 1).Value, 2)

Next i

Sql = Sql &"," &SARR(i)

Next i

Sql = Sql &" )"

cONn.Execute Sql

hh = hh + 1

Loop

End Sub

Sub connect_数据库()

Dim strconnt As String

Set connt = New ADODB.Connection

Dim rs As Object

Set rs = New ADODB.Recordset

Dim sevip, Db, user, pwd As String

'设服务器地址、所连数据，及登录用户密码

sevip = "****"

Db = "****"

user = "****"

pwd = "****"

strconnt = "DRIVER={Microsoft ODBC for Oracle}Password=appsUser ID=appsData Source=demo" '

connt.ConnectionString = strconnt

connt.Open

End Sub
