必須安裝mysql的驅動才行,不管是vb還是c++都需要這個驅動。

**如下:

public

function

exemysql(byval

sqlas

string)

asadodb.recordset

sql=

trim$(sql)

setconn

=new

adodb.connection

setrs

=new

adodb.recordset

conn.open

"driver=mysql

odbc

3.51

driver;"&_

"server=伺服器地址;"&_

"port=3306;"&_

"database=資料庫名;"&_

"uid=使用者名稱;"&_

"pwd=密碼"

conn.defaultdatabase

="資料庫名"

conn.cursorlocation

=aduseclient

setrs.activeconnection=conn

rs.locktype

=adlockbatchoptimisticrs.cursortype

=adopenkeyset

rs.open

sqlset

exesql=rs

setrs

=nothing

setconn

=nothing

endfunction

rss回報型別不匹配:也就是說插入的資料中型別有與欄位的資料型別不一致,自己檢查下

沒用mysql 我用盜版的sql:)

vb怎麼連線資料庫寫入資料?

4樓:51cto學院

'在使用前需要先安裝mysql的驅動,進行正確配置

'注意:必須給出正確的伺服器名、資料庫名、表名、資料庫連線的使用者名稱、密碼

option explicit

dim cnn as adodb.connection '定義ado連線物件

dim records as adodb.recordset '定義ado記錄集物件

'連線到資料庫

function cnnopen(byval servername as string, byval dbname as string, byval tblname as string, byval user as string, byval pwd as string) '伺服器名或ip、資料庫名、登入使用者、密碼

dim cnnstr as string '定義連線字串

set cnn = createobject("adodb.connection") '建立ado連線物件

cnn.commandtimeout = 15 '設定超時時間

cnnstr = "driver=;server=" & servername & ";database=" & dbname & ";u;pwd=" & pwd & ";stmt=set names gbk" '

cnn.connectionstring = cnnstr

cnn.open

end function

'關閉連線

function cnnclose()

if cnn.state = 1 then

cnn.close

end if

end function

'把excel寫入mysql中的資料庫

function inserttomysql(byval sheetname as string, byval tblname as string)

dim sqlstr as string

dim i, j as integer

dim columns, rows as integer

columns = vbaproject.func_public.gettotalcolumns(sheetname)

rows = vbaproject.func_public.gettotalrows(sheetname)

set records = createobject("adodb.recordset")

'取得結果集並插入資料到資料庫

set records = createobject("adodb.recordset")

'以下語句提供了插入思路,我只是把單條記錄的插入方式改為迴圈,以把所有的記錄新增到表中

'rs.open "insert into newtable values('" & activesheet.cells(i, 1).

value & "'," & "'" & activesheet.cells(i, 2).value & "')", cnn, 0

for i = 2 to rows

sqlstr = "insert into " & tblname & " values('" & sheets(sheetname).cells(i, 1).value & "'" '注意:

" values('",字母「v」之前是有空格的!!!

for j = 2 to columns

sqlstr = sqlstr & ",'" & sheets(sheetname).cells(i, j).value & "'"

next

sqlstr = sqlstr & ")"

set records = cnn.execute(sqlstr) 'rs.open sqlstr, cnn, 0 不能用這條語句實現!!!

next

msgbox "insert!", vbokonly, "excel to mysql"

end function

'清除物件

function clearobj()

set cnn = nothing

set records = nothing

end function
