How to call a Stored Procedure inside an oracle package with Entity Framework?

Question

I have a package in oracle 11g as follow:

CREATE OR REPLACE PACKAGE "HRS.PKG_TRAINING_SP" as
TYPE T_CURSOR IS REF CURSOR;

procedure GETPERSONNELTRAINIGLIST(
        personnel_Id_in in string,
        base_date_in in string,
        is_current_in in number,
        lst OUT T_CURSOR );
end;

How can I execute above procedure package (GETPERSONNELTRAINIGLIST) with Entity Framework (code-first)?

Note: I am using Entity Framwork 6.0 (code-first) and devart EF Provider for Oracle.

Updated: I am using following code:

var param1 = new OracleParameter("personnel_Id_in", OracleDbType.VarChar, "c5eb5589-8fee-47b6-85ad-261a0307cc16", ParameterDirection.Input);
var param2 = new OracleParameter("base_date_in", OracleDbType.VarChar, "1112", ParameterDirection.Input);
var param3 = new OracleParameter("is_current_in", OracleDbType.Number, 1, ParameterDirection.Input);

var ATests =
    db.Database.SqlQuery<ATest>(
    "BEGIN PKG_TRAINING_SP.GETPERSONNELTRAINIGLIST(:personnel_Id_in, :base_date_in, :is_current_in); end;", 
    param1,  param2, param3).ToList();

but below error raised:

{"ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of arguments in call to 'GETPERSONNELTRAINIGLIST'\nORA-06550: line 1, column 7:\nPL/SQL: Statement ignored"}

Solution

Please rewrite your code in the following way:

var param1 = new OracleParameter("personnel_Id_in", OracleDbType.VarChar, "c5eb5589-8fee-47b6-85ad-261a0307cc16",  ParameterDirection.Input);
var param2 = new OracleParameter("base_date_in", OracleDbType.VarChar, "1112", ParameterDirection.Input);
var param3 = new OracleParameter("is_current_in", OracleDbType.Number, 1, ParameterDirection.Input);
var param4 = new OracleParameter("result", OracleDbType.Cursor, ParameterDirection.Output);

var ATests =
db.Database.SqlQuery<ATest>(
"BEGIN PKG_TRAINING_SP.GETPERSONNELTRAINIGLIST(:personnel_Id_in, :base_date_in, :is_current_in, :result); end;", 
param1,  param2, param3, param4).ToList();

How can i put lst parameter into db.Database.SqlQuery?

[smnbbrv]

can't this be helpful? It is about ref cursor but I think there is no real problem to make it?

What is the best practice to execute all of procedures in the package?

When working with the Code-First approach, the way we have described above (via the SqlQuery method msdn.microsoft.com/en-us/library/gg679117%28v=vs.103%29.aspx ), is the most suitable. The general information regarding creating EF models with stored procedures and working with them is available here devart.com/dotconnect/oracle/docs/?OracleRoutines.html
