ref-cursor

问题 This package uses two unique features of Oracle, REF_CURSOR and a package global variable. I would like to port the functionality from Oracle to Postgresql or MySQL. PACKAGE tox IS /*=======================*/ g_spool_key spool.key%TYPE := NULL; TYPE t_spool IS REF CURSOR RETURN spool%ROWTYPE; /*=======================*/ PROCEDURE begin_spool; /*=======================*/ PROCEDURE into_spool ( in_txt IN spool.txt%TYPE ); /*=======================*/ PROCEDURE reset_spool; /*====================

问题 I am trying to execute an Oracle stored procedure using JPA. I am able to retrieve results if I build the query and call the stored procedure through the query.getResultList() as shown below: @Autowired EntityManager em; public List<MyEntity> callStoredProcedure(String paramOneValue, String paramTwoValue) { StoredProcedureQuery query = em.createStoredProcedureQuery("storedProcedureName"); query.registerStoredProcedureParameter("paramOneName", String.class, ParameterMode.IN); query

问题 I'm trying to use a RefCursor as an input parameter on an Oracle stored procedure. The idea is to select a group of records, feed them into the stored procedure and then the SP loops over the input RefCursor , doing some operations to its records. No, I can't select the records inside the SP and thus avoid having to use the RefCursor as an input type. I've found an example on how to do this on (this here would be the link, but it seems I cannot use them yet) Oracle's documentation, but it

问题 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

问题 I am trying to load data from reference cursor into a table variable (or array), the reference cursor works if the table variable is based on existingtable %Rowtype but my reference cursor gets loaded by joining multiple tables so let me try to demonstrate an example what i am trying to do and some one can help me --created table create table SAM_TEMP( col1 number null, col2 varchar(100) null ); --created procedure which outputs results from that table CREATE OR REPLACE PROCEDURE SP_OUT

问题 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

问题 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? 回答1: 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

问题 I have a function which I have written to automate the execution of a group of functions for my project. I am taking a refcursor where I am storing my required data which I will be passing as an argument to each of my functions being called and based on the argument will get executed. I am giving my code here: CREATE OR REPLACE FUNCTION ccdb.fn_automation() RETURNS void AS $BODY$ DECLARE sec_col refcursor; cnt integer; sec_code ccdb.update_qtable%ROWTYPE; new_cnt numeric; BEGIN SELECT COUNT(*
