ihave a .bat file, in which i am using sqlldr to load into a staging table from csv file, and then using merge to insert / update into target table
i have 2 doubts
1) my first doubt is regarding batch script..how to handle the errorlevels which are greater than 1?
so generally speaking, how do i handle all the errors at once..and make sure the control goes to
run_sqlldr0 always? and handle the error meaningfully if its other than 0 ?
below is my batch script, and i get error
goto run_sqlldr2
the system cannot find the batch label specified - run_sqlldr2
@echo on
call oraenv.bat
if not exist %mainpath% goto mainpath_def
if not exist %scripts% goto scriptspath_def
if not exist %logs% goto logspath_def
if not exist %data% goto datapath_def
goto x1
:x1
goto run_sqlldr%ERRORLEVEL%
echo run_sqlldr%ERRORLEVEL%
if run_sqlldr%ERRORLEVEL% NEQ 0 goto run_sqlldr1
echo "entering sqlldr"
:run_sqlldr1
echo "entered sqlldr1"
echo "some error"
echo mergedata%ERRORLEVEL%
:run_sqlldr0
echo "entered sqlldr0"
sqlldr userid = scott/tiger@orcl control=%mainpath%\cm.ctl log=%logs%\cm.log discard=%logs%\cm.dsc bad=%logs%\cm.bad SILENT=(HEADER, FEEDBACK)
goto mergedata%ERRORLEVEL%
:mergedata1
echo "entered mergedata1"
echo cleandata%ERRORLEVEL%
:mergedata0
sqlplus -s scott/tiger@orcl @%scripts%\merge_stg.sql
goto cleandata%ERRORLEVEL%
:cleandata1
echo "entered cleandata1"
echo "cleaning error"
goto exit
:cleandata0
sqlplus -s scott/tiger@orcl @%scripts%\clean_stg.sql
goto exit
:mainpath_def
echo "mainpath not existing as specified %mainpath%, Please edit ORAENV with correct value"
goto exit
:scriptspath_def
echo "scripts path not existing as specified %scripts%, Please edit ORAENV with correct value"
goto exit
:logspath_def
echo "Logs path not existing as specified %logs%, Please edit ORAENV with correct value"
goto exit
:datapath_def
echo "Data path not existing as specified %data%, Please edit ORAENV with correct value"
goto exit
:exit
2) my second doubt, is this the right way of calling the stored procedures merge_stg and clean_stg?
in clean_stg, i use dynamic sql to truncate the staging table
create or replace procedure trunstg is
lsql varchar2(2000) := 'truncate table stg_ldrtest';
begin
execute immediate lsql;
end;

i have changed the code
@echo on
call oraenv.bat
if not exist %mainpath% goto mainpath_def
if not exist %scripts% goto scriptspath_def
if not exist %logs% goto logspath_def
if not exist %data% goto datapath_def
goto x1
:x1
goto run_sqlldr%ERRORLEVEL%
echo run_sqlldr errorlevel: %ERRORLEVEL%
if run_sqlldr%ERRORLEVEL% NEQ 0 goto run_sqlldr1
echo "entering sqlldr"
:run_sqlldr1
echo "entered sqlldr1"
echo "some error"
:run_sqlldr2
echo errorlevel: %errorlevel%
echo mergedata%ERRORLEVEL%
:run_sqlldr0
echo "entered sqlldr0"
sqlldr userid = gautam/gautam@orcl control=%mainpath%\cm.ctl log=%logs%\cm.log discard=%logs%\cm.dsc bad=%logs%\cm.bad SILENT=(HEADER, FEEDBACK)
goto mergedata%ERRORLEVEL%
:mergedata1
echo "entered mergedata1"
goto end
echo cleandata%ERRORLEVEL%
:mergedata0
sqlplus -s gautam/gautam@orcl @%scripts%\merge_stg.sql
goto cleandata%ERRORLEVEL%
:cleandata1
echo "entered cleandata1"
echo "cleaning error"
goto end
:cleandata0
sqlplus -s gautam/gautam@orcl @%scripts%\clean_stg.sql
goto end
:mainpath_def
echo "mainpath not existing as specified %mainpath%, Please edit ORAENV with correct value"
goto exit
:scriptspath_def
echo "scripts path not existing as specified %scripts%, Please edit ORAENV with correct value"
goto exit
:logspath_def
echo "Logs path not existing as specified %logs%, Please edit ORAENV with correct value"
goto exit
:datapath_def
echo "Data path not existing as specified %data%, Please edit ORAENV with correct value"
goto exit
:end
EXIT
so the error is ORA - 30926, unable to get a stable set of
rows in the source tables
my merge is
MERGE INTO ldrtest D
USING (SELECT code,id,row_name,col1,col2,col3,crt_tm,md_tm,crt_user,mod_usr FROM stg_ldrtest) S
ON (d.code = s.code and d.id = s.id and d.row_name=s.row_name )
WHEN MATCHED THEN UPDATE SET d.col1 = s.col1,
d.col2 = s.col2,
d.col3 = s.col3,
d.crt_tm = s.crt_tm,
d.md_tm = s.md_tm,
d.crt_user = s.crt_user,
d.mod_usr = s.mod_usr
WHEN NOT MATCHED THEN INSERT (d.code,d.id,d.row_name,d.col1,d.col2,d.col3,d.crt_tm,d.md_tm,d.crt_user,d.mod_usr)
VALUES (s.code,s.id,S.row_name, s.col1,s.col2,s.col3,s.crt_tm,s.md_tm,s.crt_user,s.mod_usr);
i did not understand what this error means..
could anyone please help me out
