Sql question : TRUNCATE vs Delete
hi
this is sql question, i don't know where i should post it, so here it is.
i just want to know the best usage of each. both commands delete records in a table, one deletes all, and the other can do the same plus option to delete specified records. if i just want to purge the table. which one is better and why? thanksthis is crucial to my design, i need to be able to
rollback if one of the process in the transaction
failed, the whole transaction should rollback. if
truncate does not give me this capability, then i have
to consider Delete.From the Oracle manual (sans the pretty formatting):
TRUNCATE
Caution: You cannot roll back a TRUNCATE statement.
Purpose
Use the TRUNCATE statement to remove all rows from a table or cluster. By default,
Oracle also deallocates all space used by the removed rows except that specified by
the MINEXTENTS storage parameter and sets the NEXT storage parameter to the size
of the last extent removed from the segment by the truncation process.
Removing rows with the TRUNCATE statement can be more efficient than dropping
and re-creating a table. Dropping and re-creating a table invalidates the table?s
dependent objects, requires you to regrant object privileges on the table, and
requires you to re-create the table?s indexes, integrity constraints, and triggers and
respecify its storage parameters. Truncating has none of these effects.
See Also:
DELETE on page 16-55 and DROP TABLE on page 17-6 for
information on other ways to drop table data from the database
DROP CLUSTER on page 16-67 for information on dropping
cluster tables
Prerequisites
To truncate a table or cluster, the table or cluster must be in your schema or you
must have DROP ANY TABLE system privilege. -
Urgent SQL question : how to flip vertical row values to horizontal ?
Hello, Oracle people !
I have an urgent SQL question : (simple for you)
using SELECT statement, how to convert vertical row values to horizontal ?
For example :
(Given result-set)
MANAGER COLUMN1 COLUMN2 COLUMN3
K. Smith ......1
K. Smith ...............1
K. Smith ........................1
(Needed result-set)
MANAGER COLUMN1 COLUMN2 COLUMN3
K. Smith ......1 .......1 .......1
I know you can, just don't remeber how and can't find exactly answer I'm looking for. Probably using some analytic SQL function (CAST OVER, PARTITION BY, etc.)
Please Help !!!
Thanx !

I have seen the following in some sql, but not sure of the difference.
select abc, NULL from xyz where .....
select abc, to_char(NULL) from xyz where ....
my question is there a difference between NULL and TO_CHAR(NULL) ?
Thanks.BluShadow wrote:
Looks like someone was trying to cast the null to a varchar2 datatype so that SQL knew the datatype of the column. In that case they should have used the CAST function...
Blu:
Just out of curiosity, any particular reason for the preference for cast instead of to_datatype(null)? I often use that construct, particularly in union type queries. The cast is sematically meaningless in a union query since the column will get the size of the largest column in the query.
SQL> set null null
SQL> select *
2 from (select 1 id, null c1, to_char(null) c2, cast(null as varchar2(10)) c3 from dual

View created.
SQL> desc v;
Name Null? Type
ID NUMBER
C1 VARCHAR2(11)
C2 VARCHAR2(11)
C3 VARCHAR2(11)About the only place where I would use an explicit cast is if I was "hiding" the content of a column in a view, but needed to maintain the same structure as the table.

Hello. I work for Clarian Health in Indianapolis and am trying to learn as much as possible about the SQL databases, both AWDB and HDS so that I can handle the reporting for our Revenue Cycle Customer Service.
I am currently working my way through the Database Schema Handbook for Cisco Unified ICM /Contact Center Enterprise & Hosted. I’m also reviewing the explanation pages that are available for the reports on WebView. During my reviews, I have noticed a few things that confuse me.
My questions are:
1. Why do a majority of the tables on our SQL Server start with “t_”?
2. Why do some of the tables have data on the AWDB server but not on the HDS server, and vice versa? (Examples: t_Agent and t_Agent_Team and t_Agent_Team_Member and t_Person are blank on the HDS database but not blank on the AWDB database; but the t_Agent_Logout is blank on the AWDB database and not blank on the HDS database)
3. When data is moved to the HDS server every 30 minutes, is it also removed from the corresponding AWDB table?
4. In review of the agent26: Agent Consolidated Daily Report syntax info located on the WebView, 1 of the calculations uses the LoggedOnTimeToHalf from the Agent_Half_Hour table while the remaining calculations uses the same field from the Agent_Skill_Group_Half_Hour table. Can you please tell me why this is? Why would all of the percent calculations not use the data from the same table? (The % of time Agent paused and/or put a task on hold uses the Agent_Half_Hour Table. All other % calculations uses the same field from the Agent_Skill_Group_Half_Hour Table.)
5. Also in reviewing the agent26: Agent Consolidated Daily Report syntax info, I noticed that it contains the Skill_Group table, the Agent_Half_Hour table and the Media_Routing_Domain table. Both the Skill Group table and the Agen_Half_Hour table contain links to the Media_Routing_Domain table. Which relationship/join is actually utilized for this report?
6. Why doesn't the LoggedOnTimeToHalf field on both the Agent_Half_Hour table and the Agent_Skill_Group_Half_Hour table have the same value in them?
7. On the agent_26: Agent Consolidated Daily Report syntax explanation page, the Agent State Times: Log on Duration says that it is derived using the Agent_Half_Hour.LoggedOnTimeToHalf field, but when i convert this field to HH:MM:SS, it does not match the actual WebView report. But, when I use the Agent_Skill_Group_Half_Hour.LoggedOnTimeToHalfHour, it does match. Which one is correct?
8. On the agent_26: Agent Consolidated Daily Report, why does the Completed Tasks: Transfer Out contain both the TransferredOutCallsToHalf and the NetTransferredOutCallsToHalf fields? What's the difference between the two? What Transfer out data writes to each field?
Thank you.

[email protected]You need to be careful when looking at the three databases - Logger, AW, HDS - which use the same schema. But many of what appear to be tables in the AW are really views into the t_ tables in the HDS - the data is not there in the AW DB. You are right to look at the schema - but check with SQL Enterprise to understand a bit more.
In essence, the AW DB is for configuration data and real-time data. The HDS is for historical data. You can query the AW DB for (say) Call_Type_Half_Hour data and join with the Call_Type table to resolve the call type ID into its name - but the data is really in the HDS through the view.
The DB design is quite complex and sophisticated - many things are not obvious.
Keep up your research.

SQL question- on how to handle groups of records at a time.
Hi,
I have a sql that looks like the following:
insert into INVALID_DATES_TMP
(id, gid, created, t_rowid, updated)
select id, gid, created, rowid, updated
from TABLE1
where fix_invalid_date_pkg.is_date_invalid('TABLE1', 'CREATED', ROWID) = 'Y';
COMMIT;
What the above sql does is selects all rows from TABLE1 where the CREATED column
has invalid dates and inserts them into invalid_dates_tmp table. So we can process/fix
those invalid dates from the temp table. Problem is our DBA said Table1 can have
millions of rows so the above sql can be very database intensive. So, I need to
figure out another way that may handle chunks of rows at a time from table1.
Any ideas are appreciated!
ThankYou,
Radhika.Hallo,
in general INSERT AS SELECT is the fastest method to insert into the table.
Probably you can use direct load ? (Hint APPEND).
Other options (INSERT IN LOOP or BULK + FORALL) are slower.
I think, this method is optimal.
Another question is, the function itself. It is not clear, whether it searches the invalid dates optimal. I suppose strong, that function uses dynamic SQL.
Why ? It is better to search static . Or you use this function for many other columns ? Could you post the function also ?
Regards

Parent - child table issue wrt to count - SQL question
I have a scenario:
There are 2 tables (parent and child). lets say, case summary table and task level dimension table.
for every case id in case summary table, there would be multiple tasks in task level dim table with a flag indicator set to 1 for all tasks.
but while counting the number of cases active with flag indicator 1 (ofcourse when joining case summary table with task dimension table), for a case id only 1 instance of task needs to be accounted (even though it has more than one task , for counting active cases, the flag ind corresponding to a task in a case if set to 1 , then the case is considered active)..but while joining and taking count of case ids with flag indicator as 1, you get the count of every task row of a case which is incorrect logically. how to discard the rest of child records of a case in child table (task dimension table)?
I am not sure how to achieve this in sql query
Kindly help!
Case summary table
case id, busininess_unit, agent_name
1001, admin, Ram
1002, Finance, Sam
task table
case id, task_id,task_name, flag_indicator
1001, 1, 'New', 1
1001,2, 'Open',1
1001,3,'In progress',1
1002, 4, 'New', 1
(In fact task_id is not a big deal... even you can assume task id doesn't exist..only task name ... )
now my question... if my query should get the current active cases (ind=1); as per above it should essentially give 2... but my query gives me 4..you know the reason why.. but how do i get the correct count?
Thanks!may be you need just this:
select count(distinct case_id) from task
where indicator = 1;
If this is not what you are looking for, please elaborate and tell us the expected output and rest of the details as mentioned in FAQ Re: 2. How do I ask a question on the forums?: -
Hi,
I am working on a SQL, please help ms with the question
below .... thanks
(1)Increase by 10% salary of these captain pilots who have
traveled more than 800,000 miles.
Routes | | Flights | |Pilots |
| | | | |
#routeID | | #flightNO | |#pilotID |
depAirportID | | airplaneNO| |*name |
arrAirportID |_______/| pilotID |\___________|*hours_in_air|
length | \| routeID |/ |*grade |
______________| |_____________| |*salary |
|____________|If the length column in routes is in hours, and it represents
additional hours to those shown in hours_in_air in pilots, then
the following should work:
UPDATE pilots
SET salary = salary * 1.1
WHERE pilotid in (SELECT a.pilotid
FROM pilots a,
(SELECT b.pilotid,sum(c.length) new_hours
FROM flights b, routes c
WHERE b.routeid = c.routeid
GROUP BY b.pilotid) d
WHERE a.pilotid = d.pilotid and
new_hours + hours_in_air >= 80000)I suspect that you probably need to add additional criteria to
the sub-query from flights and routes to take into account only
flights since the hours_in_air column from pilots was last
updated. However, your table structures do not indicate any
date sensitivity. If the table flights is emptied every time
hours_in_air is updated, then the query above will work. -
SQL Question (Select rows with multiple records)
Hello Gurus,
I am learning SQL and have a question. Thanks for your time and help.
I have 2 tables TABLE_AA and TABLE_BB. Both tables have two columns ID, DATA.
TABLE_AA is connected to TABLE_BB through ID field (TABLE_AA.AA_DATA = TABLE_BB.BB_DATA)
TABLE_AA
~~~~~~~
AA_ID______AA_DATA
~~~~~~~~~~~~~~~~
1111_______XXXX
2222_______QQQQ

1111_______AAAA
2222_______BBBB
3333_______CCCC
3333_______DDDD
4444_______EEEE
I am looking to get those AA_ID values that have multiple in TABLE_BB for their parent reference in TABLE_BB.
So, from the above example, the sql should return the following as AA_ID 3333 has more than 1 reference value in BB_ID
AA_ID_____BB_ID

Hi,
I need to select the set of records only in Table A, but not in Table B. I think that the correct SQL is:
select k~vbeln
into data
from vbak as k
inner join vbfa as f on kvbeln = fvbelv
where f~vbelv is null.
But the following message appears: u201CNo fields from the right-hand table of a LEFT OUTER JOIN may appear in the WHERE condition: u201CF~VBELBu201Du201D.
Thanks in advance,
Ricard.Hi Oscar & William,
first of all: The database meaning of NULL is that for the field in question no value is stored for an existing record.
In SAP tables we rarely have any NULL values. Only if you extend an existing table, i.e. append a new field, the database will expand the structure but not store INITIAL values for the new field in all records.
Second, just a hint: although the SAP example uses the mystifying ALIAS (AS) addition for joins, it does not help except reducing the code transparency:
SELECT vbak~vbeln
INTO lw_data
FROM vbak
INNER JOIN vbfa ON vbak~vbeln = vbfa~vbelv
WHERE vbfa~vbelv IS NULL.
<you can do your process here>
ENDSELECT.
Is 100 % the same. Nevertheless it will never retrieve a single record because vbelv is never stored as a NULL value.
I think this can be solved using a subquery
DATA : lt_data TYPE table of vbak-vbeln.
SELECT vbeln
INTO lt_data
FROM vbak
WHERE NOT EXISTS
( SELECT * FROM vbfa WHERE vbelv = vbak~vbeln ).
<you can do your process here>
ENDSELECT.
To be honest: I did not try the code, never played with subqueries though I should do so.

Gentlemen,
I have a table in Locator that is made of of polygons (loaded via MapInfo EasyLoader). What I need to do is to send Oracle a latitude and longitude and have Oracle return the polygon in which that location falls in. I am new to loator and so this is probably an easy question. I have been experimenting with SQL statements and I tried the following:
Select MUSYM From ENCLASS_USER.SOILMU_A_IA001
Where SDO_INSIDE(sdo_geometry(2001, 8307, sdo_point_type(-94.53825,41.38343, NULL),null,null),GEOLOC) = 'TRUE'
The error returned indicates the "interface not supportrd without a spatial index". The table has a spatial index, however I think that the problem is with the latitude and longitude portion of the SQL. In the above statement, MUSYM is the value of the column in the polygon table I need returned and GEOLOC is the SDO_GEOMETRY Column. The Lat/Long coordinates are -94.53825,41.38343 in the example above.
How do I construct this SQL so that it will work?
Thansk for your help,
Tim Fast
Pioneer Hi-Bred International, Inc.The SQL that I am using is:
Select MUSYM From ENCLASS_USER.SOILMU_A_IA001
Where SDO_INSIDE
(GEOLOC,sdo_geometry(2001, 8307, sdo_point_type(-94.542208,41.383796, NULL),null,null)) = 'TRUE'
It should return the MUSYM of "370B"
I don't know how to send you the sample rows but here are three rows in which the first one is the polygon that should be returned. The columns are "|" delimited when exported form Oracle.

I am a former FoxPro programer who has just started working with the JDBC. I have a quick question about table focus. (I am picking up the JDBC Pocket Reference guide tomorrow so this will hopefully be my only silly question)
How can I retrieve the entire contents of a table to the result set without saying
SELECT * FROM TABLE
This seems this is a very slow alternative to just returning the entire table without going through the whole select process and returning a cursor filled with the data.
In FoxPro (ugh) you can say SELECT TABLE and that would bring the table into focus. Can you do this in Java or are you limited to an entire select statement by the JDBC driver?I'm not a FoxPro programmer, so I don't know what the difference is between SELECT * FROM TABLE and bringing the table into focus. If it's a remote call to a database, that data's gotta come back someway. Those bytes have to cross the network sometime. I don't see the difference, but them I'm ignorant.
Are you saying that "bringing the table into focus" allows you to grab say the first ten records and then ask for the next ten when you're ready for them?
I'm not sure, but you might be talking about a scrollable ResultSet or maybe javax.sql.RowSet.
But I don't know of any way to avoid that SELECT.
Are you 100% certain that it's a problem? Have you timed the two and compared?
I have a funny feeling that FoxPro might be doing that SELECT * FROM TABLE behind the scenes and perhaps doing some nice caching to make it look fast.
Sorry I haven't been much help. Maybe someone who knows both JDBC and FoxPro will be able to answer with authority. - MOD -
sorry guys, wasnt sure where else to put this so hope it is ok to post it here. I currently have a field in my database which stores date and time however i am writting an sql statemenet and need to only use the date of the datetime, what would be the correct syntext to do sowould i have to use to_char etc?
Thank you.Are you doing something specific to Oracle Forms? If not, you may want to consider posting your question in the SQL - PL/SQL forum (url below). If this is Forms specific, please indicate exactly which Forms version you are using. The database version you plan to use may also be helpful as there may be a variety of ways of accomplishing your goal depending on the versions.
