The SYS_REFCURSOR is a predefined weak ref cursor type supplied by Oracle9i and higher. On the other hand, you can also pass entire collections as parameters, but that’s a different issue, you don’t FETCH from collections, but process their data and/or populate them, as needed.
CR is not designed to work with OUT parameters. 5- The REF CURSOR variable must be opened and assigned its query within the procedure. 6- … The REF CURSOR type works similarly to the out and inout parameters. You set the value of the REF CURSOR as an exchange property.

So I thought that it is a nice time to write a post on "Parameterized Cursors in Oracle". Yes, Oracle does support Parameters with Cursors, like it does in case of function or procedure. Benefit of "Parameterized Cursors" if of-course reusability and - Cursor with Parameters in Oracle - Ref Cursor: Strongly Typed VS Weakly Typed - Difference Between Cursor And Ref cursor - ORA-01422: exact fetch returns more than requested number of rows Get Results from REFCURSOR with unknown number of columns in PLSQL OUT REF CURSOR. OUT REF CURSOR parameters are returned as either strongly-typed or weakly-typed result sets.
This procedure has weakly-typed IN and OUT REF CURSOR parameters and a strongly-typed IN OUT REF CURSOR parameter. Di seguito è illustrata la firma del metodo generato nel client WCF per richiamare GET_ACTIVITY. Here is the signature of the method that is generated in the WCF client to invoke GET_ACTIVITY.
When designing a form in forms 10g, is it ideal to define a data block through a REF CURSOR (as an out parameter from a db procedure) or directly through a SQL query. I have done some research on Google about using REF CURSORS and its efficiency but I am not quite sure if the ref cursor approach provides a better performance on forms.
Home / Database / Oracle Database Express Edition Documentation, 11g Release 2 (11.2). Database Creating a PL/SQL Stored Procedure that Uses REF CURSORs. Modifying Stored functions have a single return value parameter. Name:
IN OUT REF CURSOR parameters CREATE OR REPLACE PACKAGE test_package IS . This discussion is archived. 3 Replies Dec 29, 2015 · I have to execute an oracle stored procedure from test complete that returns a refcursor, I tried different ways with parameter object and also using the record set My stored procedure exm create or replace PROCEDURE TESTPROC ( retCur OUT GLOBALPKG.RCT1) AS BEGIN open retCur for SELECT mc_id, ct A REF CURSOR datatype can be obtained as an OracleDataReader object by calling the ExecuteReader method of the OracleCommand object.
None of the output parameters of type OracleDbType.RefCursor is populated after the ExecuteReader method is invoked. You can try something like this, if you need more information you have to provide more details. Create a sequence for unique no. CREATE SEQUENCE emp_seq MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 INCREMENT BY 1 CACHE 20; Without a cursor variable, you have to fetch all data from a cursor, store it in a variable e.g., a collection, and pass this variable as an argument.
For more information, see "Loading data into tables" on page 6-20. There are reports for Cache Groups. For more information, see "Cache Groups" on Hi Solmyr72, At my company we have just converted a few hundred Sybase stored procedures and functions to Oracle procedures using reference cursors. Below is a sample script showing a typical procedure using one input parameter and a reference cursor (:c1) as an output parameter. Make sure that you execute the procedure as a script by hitting F5 or selecting on the main menu > Editor To pass a cursor variable parameter between subprograms in different PL/SQL units, define the REF CURSOR type of the parameter in a package. –> SYS REF CURSOR è un evoluzione del REF_CURSOR che non necessita più della definizione. Cursor.arrayvar (dataType, value [, size]) ¶ Create an array variable associated with the cursor of the given type and size and return a variable object.The value is either an integer specifying the number of elements to allocate or it is a list and the number of elements allocated is drawn from the size of the list.
The REF CURSOR type works similarly to the out and inout parameters. You set the value of the REF CURSOR as an exchange property. To use Oracle REF CURSORs with the SQL module: Map the cursorResultMap to the java.util.HashMap class in your SQL mapper file with the
create table dept ( dept_id number, name varchar2(40), location varchar2(200) ); CREATE OR REPLACE PACKAGE HR.SP_PACKAGE AS TYPE dept_type IS REF CURSOR RETURN HR.dept%ROWTYPE; END SP_PACKAGE; CREATE OR REPLACE PROCEDURE HR.MIXED_IN_INOUT_REF_PARAM ( P_ID IN NUMBER , P_NAME_TO_LOCATION IN OUT VARCHAR2 , P_RCURSOR OUT SP_PACKAGE.dept_type ) AS BEGIN … 8/1/2016 To declare a cursor variable, you use the REF CURSOR is the data type. PL/SQL has two forms of REF CURSOR typeS: strong typed and weak typed REF CURSOR. The following shows an example of a strong REF CURSOR. DECLARE TYPE customer_t IS REF CURSOR … which has REF CURSOR as the IN OUT parameter.
Ref Cursor can be passed/returned to another PL/SQL routine (function or procedure) or even can be returned to client from the Oracle Database Server. Ref Cursors can be further categorized in 2 parts 1) Strongly Typed Ref Cursor 2) Weakly Typed Ref Cursor When a return type is included while defining Ref Cursor it called Strongly Typed Ref Cursor.citi dvojitý převod zůstatku v hotovosti na běžný účet

Oracle REF CURSOR With the REF_CURSOR you can return a recordset/cursor from a stored procedure. There are 2 basic types: Strong ref cursor and weak ref cursor For the strong ref cursor the returning columns with datatype and length need to be known at compile time.
