Hello,

We have one store procedure in oracle which returns string message in output parameter.

I want to call it from vb.net and my code for output parameter is as below.

VB.NET

Dim lineParameter As New OracleParameter("v_message", OracleType.VarChar)
lineParameter.Size = 32000
lineParameter.Direction = ParameterDirection.Output
myCMD.Parameters.Add(lineParameter)

When i execute,it only returns 22 characters from store proceudre (oracletype varchar is 22 character initially)

How can i get long message from store procedure as output parameter value.

Please help me.

Regards,

If Oracle is only returning 22 characters then you would have to change the oracle stored procedure, wouldn't you?

No because its working fine with java code.. so i think there is no issue with store procedure.

So, you are saying that if you execute the stored procedure in Oracle's tools you get more than 22 characters back but in .Net you only get 22?

Refer to https://msdn.microsoft.com/en-us/library/system.data.oracleclient.oracletype(v=vs.110).aspx and make sure to find the proper Oracle type equivalent.
