HTML reports using SQL*Plus

Using SQL*Plus it is possible to create presentable HTML reports that improve readability over traditional ASCII based reports.

A Simple report:

set markup html on 
set verify off trimspool on trimout on feedback off heading on echo off pages 100 termout off

spool currentTime1.html

select to_char(sysdate,'DD.MON.YYYY HH24:MI:SS') "Current Time" from dual
/

spool off


Output:

Current Time
06.JUN.2012 18:56:29


Taking a plain report and adding color to it and stylesheet:
spool currentTime2.html

set markup html on spool on entmap off -
 head 'The Current Time -
 ' -
 body 'text=black bgcolor=fffffff align=left' -
 table 'align=center width=99% border=3 bordercolor=black bgcolor=grey'

select 
'

' || to_char(sysdate,'DD.MON.YYYY HH24:MI:SS') ||'

' "Current Time" from dual / spool off


Output:

Current Time

06.JUN.2012 20:56:03



Color highlighting columns in the output:

set verify off trimspool on trimout on feedback off heading on echo off pages 100 termout off

set markup html on spool on entmap off -
    head 'USERENV -
    ' -
    body 'text=black bgcolor=fffffff align=left' -
    table 'align=center width=99% border=3 bordercolor=black bgcolor=grey'

define COLOR_BEGIN_GREEN = '';
define COLOR_END_GREEN = '';

spool userenv.html

select 
 sys_context('USERENV','SESSION_USER') "Session User",
 ''|| sys_context('USERENV','INSTANCE_NAME')|| 
 '' "Instance Name",
 '&COLOR_BEGIN_GREEN' || sys_context('USERENV','SERVER_HOST') ||
 '&COLOR_END_GREEN' "DB Hostname"
from dual
/

spool off


Output:

Session UserInstance NameDB Hostname
SYSlexusjupiter


Displaying columns in different colors based on a condition. This can help highlighting an issue in a report:

set verify off trimspool on trimout on feedback off heading on echo off pages 100 termout off

set markup html on spool on entmap off -
    head 'The Current Time -
    ' -
    body 'text=black bgcolor=fffffff align=left' -
    table 'align=center width=99% border=3 bordercolor=black bgcolor=grey'

define BEGIN_WARNING = '';
define END_WARNING = '';

define BEGIN_OK = '';
define END_OK = '';

column server_host new_value server_host
column instance_name new_value instance_name

select 
 sys_context('USERENV','SERVER_HOST') server_host,
 sys_context('USERENV','INSTANCE_NAME') instance_name
from dual
/

spool logMode.html

prompt 

&server_host..&instance_name - ARCHIVELOG MODE

select decode(log_mode,'NOARCHIVELOG','&BEGIN_WARNING'|| log_mode||'&END_WARNING', '&BEGIN_OK' || log_mode||'&END_OK') "

Archive Log Mode

" from v$database / spool off


Output:

jupiter.lexus - ARCHIVELOG MODE


Archive Log Mode

NOARCHIVELOG


Putting it all together, show init.ora prameters and comment, highlight problem areas in red otherwise in green:

set verify off trimspool on trimout on feedback off heading on echo off pages 100 termout off

define BEGIN_WARNING = '';
define END_WARNING = '';

define BEGIN_OK = '';
define END_OK = '';

column server_host new_value server_host
column instance_name new_value instance_name

select 
 sys_context('USERENV','SERVER_HOST') server_host,
 sys_context('USERENV','INSTANCE_NAME') instance_name
from dual
/

set markup html on spool on entmap off -
    head 'INIT.ORA Parameters - &server_host..&instance_name -
    ' -
    body 'text=black bgcolor=fffffff align=left' -
    table 'align=center width=99% border=3 bordercolor=black bgcolor=grey'

spool initParameters.html

prompt 

&server_host..&instance_name - INIT.ORA Parameters

select name "Parameter Name", value "Parameter Value", comments "Comments" from ( select name name, decode(value,null,'',value) value, case -- -- control_file_record_keep_time -- when name = 'control_file_record_keep_time' then case when value <=14 then '&BEGIN_WARNING Value of '||value|| ' potentially low for retention of RMAN backup information &END_WARNING' end -- -- destinations *dest*, dump and log destinations -- when name like '%dest%' then case when lower(value) like '%product%' then '&BEGIN_WARNING Destination possibly under the Oracle product directory '||value|| ' &END_WARNING' when lower(value) like '%temp%' or lower(value) like '%tmp%' then '&BEGIN_WARNING Destination possibly under a temporary directory!'||value|| ' &END_WARNING' end -- -- processes -- when name = 'processes' then case when value < 100 then '&BEGIN_WARNING '||name||' value '||value|| ' may be too low, see v$resource_limit max utilisation &END_WARNING' end -- -- skip_unusable_indexes -- when name = 'skip_unusable_indexes' then decode(value,'FALSE',value, '&BEGIN_WARNING '||value||' &END_WARNING') -- -- SPFILE -- when name = 'spfile' then decode(value,'?', '&BEGIN_WARNING No SPFILE set &END_WARNING', '&BEGIN_OK SPFILE in USE &END_OK') -- -- undo management -- when name = 'undo_management' then case when lower(value) != 'auto' then '&BEGIN_WARNING UNDO_MANAGEMENT is not AUTO '|| value || ' &END_WARNING' end end comments from v$parameter, v$instance ) where comments is not null order by name, value / spool off
