过程或函数＆QUOT;＆QUOT;预计参数＆QUOT;但未提供＆QUOT ;, [英] Procedure or function "" expects parameter "", which was not supplied

问题描述

我是在asp.net新的跟在后面。

i am new on asp.net with vb.code behind

我试图获取值

我的code

Dim apps As New MyApps
apps.OpenConnection()

Dim esql As New SqlCommand
esql.Connection = apps.oConn

esql.CommandText = "cekdatauploads"
esql.Parameters.Add("@value", SqlDbType.Int, 2)

esql.ExecuteNonQuery()
esql.Parameters("@value").Direction = ParameterDirection.Output

Dim nilai As Integer = esql.Parameters("@value").Value

apps.CloseConnection()

误差

The parameterized query '(@value int)cekdatauploads' expects the parameter '@value', which was not supplied.

我已经尝试执行存储prosedure

i already try execute store prosedure

declare @p int
exec [cekdatauploads] @p output
print @p

和返回0，不为空值。

在此先感谢！

推荐答案

通过交换两行试试。

esql.CommandText = "cekdatauploads"
esql.Parameters.Add("@value", SqlDbType.Int, 2)
esql.Parameters("@value").Direction = ParameterDirection.Output
esql.ExecuteNonQuery()

如果一件事， cekdatauploads 是一个strored过程中，您应在的CommandType

one more thing if, cekdatauploads is a strored procedure, you should declare it in the CommandType

esql.CommandType = CommandType.StoredProcedure
esql.CommandText = "cekdatauploads"
esql.Parameters.Add("@value", SqlDbType.Int, 2)
esql.Parameters("@value").Direction = ParameterDirection.Output
esql.ExecuteNonQuery()
