传递 CLOB TO Sys 过程 SAP HANA

Question

如何将 clob 传递给系统 rpocedure 而不会出错？

我正在尝试通过

   CALL SYS.GET_PROCEDURE_OBJECTS(CREATE PROCEDURE "IA_ATP"."ia_xsjob.xsjob_procedures_folder::atp_procedure" ( ) 
        LANGUAGE SQLSCRIPT
        SQL SECURITY INVOKER 

    AS BEGIN

    DROP TABLE IA_ATP.ATP;

    CREATE COLUMN TABLE IA_ATP.ATP AS (SELECT ATP_VIEW.*, UTCTOLOCAL(CURRENT_UTCTIMESTAMP,'EST') AS CREATE_TS FROM IA_ATP.ATP_VIEW WHERE  
    OPEN_PRICE_REQUESTS <>0
    OR TOTAL_ON_HAND <> 0 
    OR OPEN_CUSTOMER_ORDERS <> 0  
    OR OPEN_CUSTOMER_DELIVERIES <> 0 
    OR OPEN_OUTBOUND_STOS <> 0 
    OR ATP <> 0 
    OR NEGATIVE_ATP <> 0
    OR BLOCK_STOCK <> 0
    );END;

过程"SYS"."GET_PROCEDURE_OBJECTS" 尚未记录为一般用途。

但我设法从 SQL 脚本上下文中成功调用它：

有一个过程定义：

create procedure pr_test (in i int)
as
begin
declare a, b int;

    select :i into a from dummy;
    select count(*) into b from objects;

    select :a, :b, :a*:b from dummy;
end;


call pr_test(10);

将此源代码分配给CLOB 变量并使用此变量调用系统过程：

do begin
declare proc_source clob;

proc_source :='create procedure pr_test (in i int)
                as
                begin
                declare a, b int;

                    select :i into a from dummy;
                    select count(*) into b from objects;

                    select :a, :b, :a*:b from dummy;
                end;';

 CALL SYS.GET_PROCEDURE_OBJECTS(:proc_source);

end;

从系统视图PROCEDURE_OBJECTS获取procecure结果：

select * from procedure_objects;


SCHEMA_NAME PROCEDURE_NAME  OBJECT_SCHEMA   OBJECT_NAME OBJECT_TYPE_ID  OBJECT_TYPE START_POSITION  END_POSITION

SYSTEM      PR_TEST         SYS             DUMMY       32              TABLE       100             105         
SYSTEM      PR_TEST         PUBLIC          OBJECTS     128             SYNONYM     141             148

SYSTEM      PR_TEST         PUBLIC          DUMMY       128             SYNONYM     189             194         
SYSTEM      PR_TEST         SYS             DUMMY       32              TABLE       189             194
