问题描述

oracle 中的包:

Package in oracle:

create or replace package pkgsearch as
type mycursor is ref cursor;
procedure acc_search(id in varchar,cur out mycursor);
end pkgsearch;

CREATE OR REPLACE PACKAGE BODY pkgsearch AS
PROCEDURE acc_search (id in varchar,cur out mycursor) IS
BEGIN
OPEN cur FOR SELECT *
FROM account
WHERE accno = 'id';
end acc_search;
end pkgsearch;

此包用于搜索帐户记录，其中 id 作为参数传递给程序.VB中的代码

This package is used to search account records where id is passed as paramter to procedure. Code in VB

dim con as new ADODB.connection
Dim rs As New ADODB.Recordset
Dim cmd As New ADODB.Command
Dim param As New ADODB.Parameter
Dim str As String

con.open "dsn=xxxxx;uid=xxxxxx;pwd=xxxxxx"

With cmd
.ActiveConnection = con
.CommandText = "pkgsearch.acc_search"
.CommandType = adCmdStoredProc
Set param = .CreateParameter("id", adVarChar, adParamInput, 10, Text1.Text)
.Parameters.Append param
End With

Set rs = cmd.Execute

Text1.Text = rs.Fields(0).Value
Text2.Text = rs.Fields(1).Value

推荐答案

我不确定是否使用 Oracle，但我认为它与 SQL 几乎相同.

I am not sure about using Oracle but I assume its almost the same as SQL.

这是我用于 SQL 的:

This is what I used for SQL:

sql = "exec STORED PROCEDURE HERE"
Set RS = ExecuteQuery(sql)
RS.MoveFirst

While not EOF
DO STUFF
RS.MoveNext
Wend
