I am using Oracle SQL (in SQLDeveloper, so I don't have access to SQLPLUS commands such as COLUMN) to execute a query that looks something like this:
select assigner_staff_id as staff_id, active_flag, assign_date,
complete_date, mod_date
from work where assigner_staff_id = '2096';
The results it give me look something like this:
STAFF_ID ACTIVE_FLAG ASSIGN_DATE COMPLETE_DATE MOD_DATE
---------------------- ----------- ------------------------- ------------------------- -------------------------
2096 F 25-SEP-08 27-SEP-08 27-SEP-08 02.27.30.642959000 PM
2096 F 25-SEP-08 25-SEP-08 25-SEP-08 01.41.02.517321000 AM
2 rows selected
This can very easily produce a very wide and unwieldy textual report when I'm trying to paste the results as a nicely formatted quick-n-dirty text block into an e-mail or problem report, etc. What's the best way to get rid of all tha extra white space in the output columns when I'm using just plain-vanilla Oracle SQL? So far all my web searches haven't turned up much, as all the web search results are showing me how to do it using formatting commands like COLUMN in SQLPLUS (which I don't have).
In your statement, you can specify the type of output you're looking for:
select /*csv*/ col1, col2 from table;
select /*Delimited*/ col1, col2 from table;
there are other formats available such as xml, html, text, loader, etc.
You can change the formatting of these particular options under tools > preferences > Database > Utilities > Export
Be sure to choose Run Script rather than Run Statement.
* this is for Oracle SQL Developer v3.2
What are you using to get the results? The output you pasted looks like it's coming from SQL*PLUS. It may be that whatever tool you are using to generate the results has some method of modifying the output.
By default Oracle outputs columns based upon the width of the title or the width of the column data which ever is wider.
If you want make columns smaller you will need to either rename them or convert them to text and use substr() to make the defaults smaller.
select substr(assigner_staff_id, 8) as staff_id,
active_flag as Flag,
to_char(assign_date, 'DD/MM/YY'),
to_char(complete_date, 'DD/MM/YY'),
mod_date
from work where assigner_staff_id = '2096';
What you can do with sql is limited by your tool. SQL Plus has commands to format the columns but they are not real easy to use.
One quick approach is to paste the output into excel and format it there or just attach the spreadsheet. Some tools will save the output directly as a spreadsheet.
Nice question. I really had to think about it.
One thing you could do is change your SQL so that it only returns the narrowest usable columns.
e.g. (I'm not very hot on oracle syntax, but something similar should work):
select substring( convert(varchar(4), assigner_staff_id), 1, 4 ) as id,
active_flag as act, -- use shorter column name
-- etc.
from work where assigner_staff_id = '2096';
Does that make sense?
If you were doing this on unix/linux, I would suggest running it from the command line and piping it through an awk script.
If I've miss-understood, then please update your question and I'll have another go :)
If you don't have alot of rows returned I'll often use Tom Kytes print_table function.

If its lots of rows, i'll just do the query in SQL Developer and save as xls, businessy types love excel for some reason.
Why not just use the "cast" function?
select
(cast(assigner_staff_id as VARCHAR2(4)) AS STAFF_ID,
(cast(active_flag as VARCHAR2(1))) AS A,
(cast(assign_date as VARCHAR2(10))) AS ASSIGN_DATE,
(cast(COMPLETE_date as VARCHAR2(10))) AS COMPLETE_DATE,
(cast(mod_date as VARCHAR2(10))) AS MOD_DATE
from work where assigner_staff_id = '2096';

So I'm learning how to define custom functions in PL/SQL. When I use any of the functions I've defined in a regular SELECT statement the script output gets a ton of dashes added and the readability suffers. I'm using the latest version of SQL developer.
What I want it to look like:
SELECT dtstage, idstage
FROM bb_basketstatus
WHERE idbasket = 4;
DTSTAGE IDSTAGE
--------- ----------
13-FEB-12 1
13-FEB-12 5
What I get:
SELECT dtstage, status_desc_sf(idstage) Description
FROM bb_basketstatus
WHERE idbasket = 4;
DTSTAGE
---------
DESCRIPTION

Is there a setting in SQL developer or something I'm missing the function definition?
That's just a SQLPlus / SQLDeveloper script display issue.
You can manually set the width of the column with the column ... format command:
column description format a50
select dtstage, status_desc_sf(idstage) description
from bb_basketstatus
where idbasket = 4;
It might also be useful to increase the default width of the lines (which defaults to 80), eg:
set linesize 120
I am trying to find a way to capture relevant errors from oracle alertlog. I have one table (ORA_BLACKLIST) with column values as below (these are the values which I want to ignore from
V$DIAG_ALERT_EXT)
Below are sample data in ORA_BLACKLIST table. This table can grow based on additional error to ignore from alertlog.
ORA-07445%[kkqctdrvJPPD
ORA-07445%[kxsPurgeCursor
ORA-01013%
ORA-27037%
ORA-01110
ORA-2154
V$DIAG_ALERT_EXT contains a MESSAGE_TEXT column which contains sample text like below.
ORA-01013: user requested cancel of current operation
ORA-07445: exception encountered: core dump [kxtogboh()+22] [SIGSEGV] [ADDR:0x87] [PC:0x12292A56]
ORA-07445: exception encountered: core dump [java_util_HashMap__get()] [SIGSEGV]
ORA-00600: internal error code arguments: [qercoRopRowsets:anumrows]
I want to write a query something like below to ignore the black listed errors and only capture relevant info like below.
select
dae.instance_id,
dae.container_name,
err_count,
dae.message_level
from
ORA_BLACKLIST ob,
V$DIAG_ALERT_EXT dae
where
group by .....;
Can someone suggest a way or sample code to achieve it?
I should have provided the exact contents of blacklist table. It currently contains some regex (perl) and I want to convert it to oracle like regex and compare with v$diag_alert_ext message_text column. Below are sample perl regex in my blacklist table.
ORA-0(,|$| )
ORA-48913
ORA-00060
ORA-609(,|$| )
ORA-65011
ORA-65020 ORA-31(,|$| )
ORA-7452 ORA-959(,|$| )
ORA-3136(,|)|$| )
ORA-07445.[kkqctdrvJPPD
ORA-07445.[kxsPurgeCursor –
Your blacklist table looks like like patterns, not regular expressions.
You can write a query like this:
select dae.* -- or whatever columns you want
from V$DIAG_ALERT_EXT dae
where not exists (select 1
from ORA_BLACKLIST ob
where dae.message_text like ob.<column name>
);
This will not have particularly good performance if the tables are large.
I'd like to create a table name in Hive using variable substitution.
E.g.
SET market = "AUS";
create table ${hiveconf:market_cd}_active as ... ;
But it fails. Any idea how it can be achieved?
You should use backtrics (``) for name for that, like:
SET market=AUS;
CREATE TABLE `${hiveconf:market}_active` AS SELECT 1;
DESCRIBE `${hiveconf:market}_active`;
Example run script.sql from beeline:
$ beeline -u jdbc:hive2://localhost:10000/ -n hadoop -f script.sql
Connecting to jdbc:hive2://localhost:10000/
...

Markovitz's criticisms are correct, but do not produce a correct solution. In summary, you can use variable substitution for things like string comparisons, but NOT for things like naming variables and tables. If you know much about language compilers and parsers, you get a sense of why this would be true. You could construct such behavior in a language like Java, but SQL is just too crude.
Running that code produces an error, "cannot recognize input near '$' '{' 'hiveconf' in table name".(I am running Hortonworks, Hive 1.2.1000.2.5.3.0-37).
I spent a couple hours Googling and experimenting with different combinations of punctuation, different tools ranging from command line, Ambari, and DB Visualizer, etc., and I never found any way to construct a table name or a field name with a variable value. I think you're stuck with using variables in places where you need a string literal, like comparisons, but you cannot use them in place of reserved words or existing data structures, if that makes sense. By example:
--works
drop table if exists user_rgksp0.foo;
-- Does NOT work:
set MY_FILE_NAME=user_rgksp0.foo;
--drop table if exists ${hiveconf:MY_FILE_NAME};
-- Works
set REPORT_YEAR=2018;
select count(1) as stationary_event_count, day, zip_code, route_id from aaetl_dms_pub.dms_stationary_events_pub
where part_year = '${hiveconf:REPORT_YEAR}'
-- Does NOT Work:
set MY_VAR_NAME='zip_code'
select count(1) as stationary_event_count, day, '${hiveconf:MY_VAR_NAME}', route_id from aaetl_dms_pub.dms_stationary_events_pub
where part_year = 2018
The qualifies should be removed
You're using the wrong variable name
SET market=AUS; create table ${hiveconf:market}_active as select 1;
The parameterization example in the "SQL Parameters" IPython notebook in the datalab github repo (under datalab/tutorials/BigQuery/) shows how to change the value being tested for in a WHERE clause. Is it possible to use a parameter to change the name of a field being SELECT'd on?
eg:
SELECT COUNT(DISTINCT $a) AS n
FROM [...]
After I received the answer below, here is what I have done (with a dummy table name and field name, obviously):
%%sql --module test01
DEFINE QUERY get_counts
SELECT $a AS a, COUNT(*) AS n
FROM [project_id.dataset_id.table_id]
GROUP BY a
ORDER BY n DESC
table = bq.Table('project_id.dataset_id.table_id')
field = table.schema['field_name']
bq.Query(test01.get_counts,a=field).sql
bq.Query(test01.get_counts,a=field).results()
You can use a field from a Schema object (eg. given a table, get a specific field via table.schema[fieldname]).
Or implement a custom object with a _repr_sql_ method. See: https://github.com/GoogleCloudPlatform/datalab/blob/master/sources/lib/api/gcp/bigquery/_schema.py#L49
I have tried a few different ways to list the db properties and have come up short.
SQL> SHOW DATABASE VERBOSE emp;
SP2-0158: unknown SHOW option "DATABASE"
SP2-0158: unknown SHOW option "VERBOSE"
SP2-0158: unknown SHOW option "emp"
Heres another that I dont understand why its not working
SQL> show database;
SP2-0158: unknown SHOW option "database"
SQL> DGMGRL
SP2-0042: unknown command "DGMGRL" - rest of line ignored.
Does anyone have ideas as to what I am missing.
There's a table called database_properties - you should query that
select property_name, property_value, description from database_properties
If this isn't what you're looking for, you should be more specific
If you wan the full version information for your DB then:
SELECT *
FROM v$version;
If you want your DB parameters then:
SELECT *
FROM v$parameter;
If you want more information about your DB instance then:
SELECT *
FROM v$database;
If you want the database properties then:
SELECT *
FROM database_properties;
If you want the "size" of your database then this will give you a close enough calculation:
SELECT SUM(bytes / (1024*1024)) "DB Size in MB"
FROM dba_data_files;
You will need DBA level permissions to see these views or you could request the data from your DBA and he will (probably) oblige.
Hope it helps...
SHOW DATABASE is not a valid SQL*Plus command.
The correct syntax is SHOW option where option is one of:
