sql on '&' character in Oracle

Escape ampersand (&) characters in SQL*Plus

When using SQL*Plus, the DEFINE setting can be changed to allow &'s (ampersands) to be used in text:


SET DEFINE ~
SELECT 'Lorel & Hardy' FROM dual;
Other methods:

Define an escape character:


SET ESCAPE '\'
SELECT '\&abc' FROM dual;
Don't scan for substitution variables:


SET SCAN OFF
SELECT '&ABC' x FROM dual;

to convert systimestamp to Any other time zone

The fuction is from_tz

SELECT FROM_TZ(to_timestamp(to_char(systimestamp,'DD-MON-YYYY HH:MI:SS PM')) ,'+05:30') AT TIME ZONE '-06:00',systimestamp from dual;

and one more fn.

select LOCALTIMESTAMP AT TIME ZONE '-6:00' from dual;

Oracle Table OUTPUT to CSV

(1st Method)
set colsep ','
set pagesize 0
set feedback off
set trimspool on
set linesize 1000
spool myfile.csv
select * from mytable;
spool off

(2nd Method)

create or replace function dump_csv( p_query in varchar2,
p_separator in varchar2
default ',',
p_dir in varchar2 ,
p_filename in varchar2 )
return number
AUTHID CURRENT_USER
is
l_output utl_file.file_type;
l_theCursor integer default dbms_sql.open_cursor;
l_columnValue varchar2(2000);
l_status integer;
l_colCnt number default 0;
l_separator varchar2(10) default '';
l_cnt number default 0;
begin
l_output := utl_file.fopen( p_dir, p_filename, 'w' );

dbms_sql.parse( l_theCursor, p_query, dbms_sql.native );

for i in 1 .. 255 loop
begin
dbms_sql.define_column( l_theCursor, i,
l_columnValue, 2000 );
l_colCnt := i;
exception
when others then
if ( sqlcode = -1007 ) then exit;
else
raise;
end if;
end;
end loop;

dbms_sql.define_column( l_theCursor, 1, l_columnValue,
2000 );

l_status := dbms_sql.execute(l_theCursor);

loop
exit when ( dbms_sql.fetch_rows(l_theCursor) <= 0 );
l_separator := '';
for i in 1 .. l_colCnt loop
dbms_sql.column_value( l_theCursor, i,
l_columnValue );
utl_file.put( l_output, l_separator ||
l_columnValue );
l_separator := p_separator;
end loop;
utl_file.new_line( l_output );
l_cnt := l_cnt+1;
end loop;
dbms_sql.close_cursor(l_theCursor);

utl_file.fclose( l_output );
return l_cnt;
end dump_csv;
/


You would use that for example like this:

create or replace procedure test_dump_csv
as
l_rows number;
begin
l_rows := dump_csv( 'select *
from all_users
where rownum < 25',
',', '/tmp', 'test.dat' );
end;
/

How to Create RMAN Catalog

To create the recovery catalog schema in the recovery catalog database:

Start SQL*Plus and then connect with administrator privileges to the database containing the recovery catalog. For example, enter:

1) sql> CONNECT SYS/oracle@catdb AS SYSDBA

Create a user and schema for the recovery catalog. For example, enter:

sql > CREATE USER rman IDENTIFIED BY cat
TEMPORARY TABLESPACE temp
DEFAULT TABLESPACE tools
QUOTA UNLIMITED ON tools;
*************************************
Grant the Permission as mention below.
**************************************
sql> GRANT RECOVERY_CATALOG_OWNER TO rman;
sql> grant connect , resource to rman;
**************************************
Now Create Catalog
**************************************
RMAN> CONNECT CATALOG rman/cat@catdb
RMAN> CREATE CATALOG TABLESPACE cat_ts;
**************************************
SQL> SELECT TABLE_NAME FROM USER_TABLES;
