ref-cursor

Need to access a procedure that return setof refcursor from PostgreSQL. I am able to access the first object but not rest of object not rest of objects. con.setAutoCommit(false); try (CallableStatement proc = con.prepareCall("{ ? = call usp_sel_article_initialdata_new1() }")) { proc.registerOutParameter(1, Types.OTHER); proc.execute(); ResultSet results = (ResultSet) proc.getObject(1); while (results.next()) { System.out.println("Result Id" + results.getString(1)); System.out.println("Results Name" + results.getString(2)); } This give me the first refcursor values but when i try to use second

I want to write PL/SQL to test a function in a package. The package defines a cursor type TYPE ref_cursor IS REF CURSOR; I want to define a record based on that type. My code is: DECLARE cur PACKAGE_NAME.ref_cursor; rec cur%ROWTYPE; why is last line not correct? You can't define a record type based on a weakly-typed REF CURSOR. Since the cursor type defined in the package can be used to return data from an arbitrary query with arbitrary columns, the PL/SQL compiler can't determine an appropriate record type to fetch the data into. If you know the actual data being returned from the function,

Many RDBMS support "CURSOR" types of some sort. Those types are mostly useful when returned from stored procedures. An example in Oracle: TYPE t_cursor_type IS REF CURSOR; CREATE PROCEDURE p (c OUT t_cursor_type); When calling this procedure using JDBC, the OracleTypes.CURSOR = -10 "JDBC" type should be used. This type is not part of any standard and it is not going to be part of JDBC 4.1 in Java 7. Does anyone know whether the JSR guys will consider adding this type to the standard some time in the future? Or if other RDBMS have a similar "vendor-specific type"? Support for REF CURSORS was

I am using Postgresql 8.3 and have the following simple function that will return a refcursor to the client CREATE OR REPLACE FUNCTION function_1() RETURNS refcursor AS $$ DECLARE ref_cursor REFCURSOR; BEGIN OPEN ref_cursor FOR SELECT * FROM some_table; RETURN (ref_cursor); END; $$ LANGUAGE plpgsql; Now , I can use the following SQL commands to call this function and manipulate the returned cursor ,but the cursor name is automatically generated by the PostgreSQL BEGIN; SELECT function_1(); --It will output the generated cursor name , for example , "<unnamed portal 11>" ; FETCH 4 from "<unnamed

In continuing from a previous case that was assisted by @Erwin Brandstetter and @Craig Ringer, I have fixed my code to become as follows. Note, that my function myresult() outputs now text , and not a table (as indeed, as was pointed out in the former case, there is no point in outputting a table object, since we would need to define all its columns ahead, which basically defies the entire purpose): CREATE OR REPLACE FUNCTION myresult(mytable text, myprefix text) RETURNS text AS $func$ DECLARE myoneliner text; BEGIN SELECT INTO myoneliner 'SELECT ' || string_agg(quote_ident(column_name::text),

In Oracle I can declare a reference cursor... TYPE t_spool IS REF CURSOR RETURN spool%ROWTYPE; ...and use it to pass a cursor as the return value... FUNCTION end_spool RETURN t_spool AS v_spool t_spool; BEGIN COMMIT; OPEN v_spool FOR SELECT * FROM spool WHERE key = g_spool_key ORDER BY seq; RETURN v_spool; END end_spool; ...and then capture it as a result set using JDBC... private Connection conn; private CallableStatement stmt; private OracleResultSet rset; [...clip...] stmt = conn.prepareCall("{ ? = call " + call + "}"); stmt.registerOutParameter(1, OracleTypes.CURSOR); stmt.execute(); rset

I'm looking for a good explanation on how to test an Oracle stored procedure in SQL Developer or Embarcardero Rapid XE2. Thank you. Something like create or replace procedure my_proc( p_rc OUT SYS_REFCURSOR ) as begin open p_rc for select 1 col1 from dual; end; / variable rc refcursor; exec my_proc( :rc ); print rc; will work in SQL*Plus or SQL Developer. I don't have any experience with Embarcardero Rapid XE2 so I have no idea whether it supports SQL*Plus commands like this. DCookie Something like this lets you test your procedure on almost any client: DECLARE v_cur SYS_REFCURSOR; v_a
