我正在尝试使用VBA将记录集检索回ADODB对象。我在 Oracle(11g) 数据库包中有一个非常基本的功能:
CREATE OR REPLACE PACKAGE "DATABASE"."PKG_INDEX" AS
FUNCTION get_diary(event_date IN DATE := NULL) RETURN SYS_REFCURSOR;
END PKG_AIT_INDEX;
CREATE OR REPLACE PACKAGE BODY "DATABASE"."PKG_INDEX" AS
FUNCTION get_diary(event_date IN DATE := NULL)
RETURN SYS_REFCURSOR
IS
my_cursor SYS_REFCURSOR;
search_date EVENTS.EVENT_DATE%TYPE;
BEGIN
If event_date Is Null Then
search_date := TRUNC(SYSDATE);
Else
search_date := event_date;
END IF;
OPEN my_cursor FOR
SELECT *
FROM Table
WHERE EVENT_DATE > search_date;
RETURN my_cursor;
END get_diary;
END PKG_INDEX;
在 DB Visualiser 中调用时,该函数的行为与预期相同:
--/
DECLARE
rc SYS_REFCURSOR;
BEGIN
rc := PKG_INDEX.GET_DIARY(NULL);
END;
/
我想从 VBA 调用函数并获取记录集。我尝试了许多不同的方法,但无法提出解决方案。
Public Function ExecuteFunction(sDBName As String, sDBEnv As String, sDBRegion As String, sCommand As String, Optional sDBConn As String, Optional sError As String) As Recordset
Dim oConn As ADODB.Connection
Dim oCmd As ADODB.Command
Dim oParam As ADODB.Parameter
Dim oRst As ADODB.Recordset
Const SOURCE As String = "ExecuteQuery"
If GetDBConnection(oConn, sDBName, sDBEnv, sDBRegion, sDBConn, sError) Then
Set oCmd = New ADODB.Command
With oCmd
Set .ActiveConnection = oConn
.CommandType = adCmdText
.CommandText = "BEGIN :returnValue :=PKG_INDEX.GET_DIARY; END;"
Set oParam = .CreateParameter("returnValue", adVariant, adParamInputOutput, 100000)
.Parameters.Append oParam
Set oRst = .Execute
End With
Set ExecuteFunction = oRst
End If
End Function
以上是一次尝试,但没有任何内容传递回参数,我得到:
ORA-01008: not all variables bound
我的连接字符串是:
Provider=MSDAORA;User ID=XXX;Password=XXX;Data Source=(DESCRIPTION = (ADDRESS_LIST
= (ADDRESS = (PROTOCOL = TCP)(HOST = XXXX)(PORT = XXXX)) ) (CONNECT_DATA = (SID = XXXX)));
似乎很难实现很容易的事情。
任何帮助或建议将不胜感激。
终于找到了一个很好的例子:
或者使用 CreatePLSQLDynaset 方法:
