Answer 1

ok!, the last code can work. but i don`t know what happen with "fetch next" or with other thing....
because now the problem is when call the function: DB02_GET_TB_DETL_ANALYSIS_DB2.
this send  a dump:
Table does not exist in database.
The termination occurred in line 26 of the source code of the (Include)
program "LDB02_DB2U20"
of the source code of program "LDB02_DB2U20" (when calling the editor 260).
Processing was terminated because the exception "CX_SY_NATIVE_SQL_ERROR"
occurred in the
procedure "DB02_GET_TB_DETL_ANALYSIS_DB2" "(FUNCTION)" but was not handled
locally, not declared in the
RAISING clause of the procedure.
The procedure is in the program "SAPLDB02_DB2 ". Its source code starts in line
7
of the (Include) program "LDB02_DB2$20 ".
and indicate this part in the code of the function:
000240 ?
000250 ?   EXEC SQL.
     > ?     SELECT NAME, CREATOR,
000270 ?            TYPE, DBNAME,
000280 ?            TSNAME, COLCOUNT,
000290 ?            NPAGES, KEYCOLUMNS,
