Passing array to Oracle procedure from c#
arrays, c#, oracle, stored-procedures
Solution
Define an array type and a procedure:
CREATE or replace PACKAGE Testpackage AS
TYPE Areas_t is table of VARCHAR(100) index by BINARY_INTEGER;
PROCEDURE TESTPROCEDURE(Areas IN Areas_t);
END Testpackage;
C# routine:
public void InsertQuestion(IEnumerable<string> area_list)
{
var connect = new OracleConnection("YOUR CONNECTION STRING");
var command = new OracleCommand("BEGIN Testpackage.Testprocedure(:Areas); END;", connect);
connect.Open();
var arry = command.Parameters.Add("Areas", OracleDbType.Varchar2);
arry.Direction = ParameterDirection.Input;
arry.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
arry.Value = area_list.ToArray();
arry.Size = area_list.Count();
arry.ArrayBindSize = area_list.Select(_ => _.Length).ToArray();
arry.ArrayBindStatus = Enumerable.Repeat(OracleParameterStatus.Success, area_list.Count()).ToArray();
command.ExecuteNonQuery();
connect.Close();
}
Problem
I'm trying to pass an array to oracle procedure. I searched about it and firstly i created a type named 'dizi' (like here enter link description here). So it works in oracle developer. The problem is; i can't pass my c# array to procedure as a parameter. So how can i pass my array to my procedure? Here is my code (When i execute, oracle error says: Not all variables bound) ``` public void InsertQuestion(List<string> area_list) { quest_areas = area_list.ToArray(); command.Connection = connect; connect.Open(); var arry = command.Parameters.Add("Areas", OracleDbType.Varchar2); arry.Direction = ParameterDirection.Input; arry.CollectionType = OracleCollectionType.PLSQLAssociativeArray; arry.Value = quest_areas; command.CommandText ="TESTPROCEDURE(:Areas)"; command.CommandType = CommandType.StoredProcedure; command.ExecuteNonQuery(); connect.Close(); } ```
