问题描述
我已经编写了代码来插入用 oracle pl/sql 编写的调用参数化存储过程.我已经正确地给出了所有参数,如下面的代码所示.
I have written code to insert call parameterized stored procedure written in oracle pl/sql. I have given all parameters properly as displayed in below code.
function CallSp(str_id, ref_no, note, userId, strdatestamp, writtenDate)
Dim strcon2 : set strcon2=server.createObject("ADODB.Connection")
Dim strcmd2
Dim sql2
Dim ReturnVal
strcon2.Open "Proper Connectionstring provided here"
sql2 = "Fr_Store_Notes"
Set strcmd2 = Server.CreateObject("ADODB.Command")
Set strcmd2.ActiveConnection = strCOn2
strcmd2.CommandText = sql2
strcmd2.CommandType = 4
strcmd2.Parameters.Refresh
strcmd2.Parameters.Append strcmd2.CreateParameter("p_str_id", 12,1)
strcmd2.Parameters("p_str_id") = str_id
strcmd2.Parameters.Append strcmd2.CreateParameter("p_ref_no", 12,1)
strcmd2.Parameters("p_ref_no") = ref_no
strcmd2.Parameters.Append strcmd2.CreateParameter("p_UserId", 12,1)
strcmd2.Parameters("p_UserId") = userId
strcmd2.Parameters.Append strcmd2.CreateParameter("p_note", 12,1)
strcmd2.Parameters("p_note") = note
strcmd2.Parameters.Append strcmd2.CreateParameter("p_Datestamp", 12,1)
strcmd2.Parameters("p_Datestamp") = strdatestamp
strcmd2.Parameters.Append strcmd2.CreateParameter("p_WrittenDate", 12,1)
strcmd2.Parameters("p_WrittenDate") = writtenDate
strcmd2.Parameters.Append strCmd2.CreateParameter("p_return", 3, 2)
strcmd2.Execute
ReturnVal = strcmd2.Parameters("p_return").Value
CallSp=ReturnVal
set strCmd2=Nothing
strCon2.close
end function
但我收到错误
strcmd2.Execute
数据库存储过程如下所示,如果我们从数据库中执行它就可以正常工作
Database stored procedure is as like below and working fine if we execute it from database
create or replace
procedure Fr_Store_Notes (
P_STR_ID IN VARCHAR2,
p_Ref_no in VARCHAR2,
P_UserId in VARCHAR2,
P_Note IN VARCHAR2,
P_datestamp IN VARCHAR2,
p_WrittenDate IN VARCHAR2,
p_return OUT number)
AS
BEGIN
--Expected Code Block is there and working fine
End;
谁能帮我解决这个问题
推荐答案
更新: - 显然经过一些研究(因为我不使用 Oracle)ADODB 不支持 adVariant
(即 12
),你应该使用 adVarChar
(即200
) 代替.
Update: - Apparently after a bit of research (as I don't work with Oracle) ADODB doesn't support adVariant
(which is 12
) and you should use adVarChar
(which is 200
) instead.

将其余答案留在下面,因为一旦此问题得到解决,它可能仍然相关.
Leaving the rest of the answer below as it's probably still relevant once this issue is fixed.
一旦 ADODB 与连接定义的提供者对话,导致该特定错误的原因通常是数据类型不匹配.
The cause is of that particular error is usually a mismatch of data type once the ADODB talks to the provider defined by the connection.
仅查看 Oracle 中的过程定义与您的 ADODB.Command
对象相比,我可以看到 p_return
参数似乎不正确.我在 previous answer 对 类似问题.
Just looking at the procedure definition in Oracle in comparison to your ADODB.Command
object I can see that the p_return
parameter appears to be incorrect. I talk about this in a previous answer to a similar question.
根据数据类型映射 (ADO 中数据类型映射的绝佳资源) adInteger
(即 3
) 映射到 Int
在 Oracle 中不是 Number
.相反,您应该使用 adNumeric
(即 131
) 来修复该特定错误.
According to Data Type Mapping (a great resource for Data Type Mapping in ADO) adInteger
(which is 3
) maps to Int
in Oracle not Number
. Instead, you should use adNumeric
(which is 131
) which should fix that particular error.
尝试更改此行
strcmd2.Parameters.Append strCmd2.CreateParameter("p_return", 3, 2)
到
strcmd2.Parameters.Append strCmd2.CreateParameter("p_return", 131, 2)
