Finding 10 Most Recent Missions
Jun 23, 2008What i have is table with:
mission_id, mission_type_id, security_level and code_name.
What i have to do is get the 10 most recent missions and change their security level to the highest one in their mission_type_id but ONLY if code_name length is >7
So far I have this, the problem is that the oracle moans about the order and wants me to close the bracket before the order
sql
UPDATE missions m
SET m.security_level = (
SELECT max(m2.security_level)
FROM missions m2
WHERE m2.mission_type_id = m.mission_type_id
AND length(m2.code_name) > 7
)
WHERE m.mission_ID IN (
Select m3.mission_id
From missions m3
ORDER BY m3.mission_id desc)
Create A Copy Of Missions Table Called AM_X_442_2
Jan 22, 2009My solution to the following question update 10 rows. It should update only 6 records. Create a copy of the missions table called AM_X_442_2. For missions on this table that meet the following criteria:
1. within the 10 most recent missions
2. length of the first word of the mission code_name exceeds 7 characters
Change the security level to the highest security level found in missions of the same type.
UPDATE
AM_X_442_2 am
SET
am.SECURITY_LEVEL =
(
SELECT
MAX(amx.SECURITY_LEVEL)
FROM
AM_X_442_2 am
INNER JOIN
AM_X_442_2 amx

Updating Rows To Highest Security Level Of Missions Of Same Type
Jan 25, 2009I am trying to update the security_level of a mission to the highest security level of missions of the same type.
Attributes of the missions table:
mission_id, code_name, mission_type_id, mission_date, security_level
The following is an intermediate output.
MISSION_ID MISSION_TYPE_ID SECURITY_LEVEL
318 3 6
329 3 2
286 5 6
521 5 3
281 6 4
396 7 3
331 8 4
14 9 4
230 9 0
486 10 2
The maximum output for each mission_type_id
MAX_LEVEL TYPE
6 3
6 5
4 6
3 7
4 8
4 9
2 10
According to this 3 records (329,521 and 230) should update.
But my code returns an error.
ERROR at line 4:
cannot update (......"SECURITY_LEVEL") to NULL
this is my code
UPDATE
AM_X_442_2 amx
SET
Amx.SECURITY_LEVEL =

I have intended the query to make it legible but it removes all spaces.

Display Different Number Of Rows?
Jan 23, 2009i have a table displaying location, cost, inner_num and rownum ordered by the descending order of the cost.

How To Display Hierarchy List
Oct 1, 2009query in order to display a hierarchy list. Example:
Database has three tables
Heading --> id, status, order, title
Sub-heading --> id, status, order, title, heading_id
Item --> id, status, order, title, heading_id, sub-heading_id, actual_content
order = the sequence in which they are to be displayed a sub-heading's heading_id refers to the parent heading, likewise an item's sub-heading_id refers to the parent sub-heading.
I assumed there was no need to track child content.
Now, the output format should be something like this, where the sub-headings are not repeated, nor are the items. Sort of like chapters in a book, things in a catalogue, or even topics in a forum.
Heading 1
Sub-heading 1
Item 1
Item 2
Item 3
Sub-heading 2
Item 1
Item 2
Item 3
Heading 2
Sub-heading 1
Item 1
Item 2
Item 3
Heading 3
Sub-heading 1
Item 1
Item 2
Item 3
Sub-heading 2
Item 1
Item 2
Item 3
Sub-heading 3
Item 1
Item 2
Item 3
Where I'm getting hung up is how to query the data so it's quick, efficient, clean and easy to read and maintain. I've only gotten to listing the sub-headings and already the query looks convoluted. So, how should I approach this? Should it be done all in one query, and always checking against the results to know when to print a new heading or sub heading. Or should I run multiple queries and save the results to a variable, and then run sub-queries off that? Is there a better way to do this, am I going about it the hard way or am I in the right direction and just haven't gone far enough with it yet?
