I have two table the first one is with 3 columns As
CR_GENERAL:
CRNO, | mainCR | CR status
-------|--------|------------
555 | Null | not act
5647 | 555 | act
7845 | 555 | not act
434 | Null | act
566 | 434 | act
675 | null | not act
778 | null | act
768 | null | Can
8668 | 555 | can
Second table (IDENTIFICATIONS):
Cr | partner
--------|---------
555 | 23453
434 | 23555
768 | 26653
8668 | 23453
5647 | 23453
First thing I want to do is :
to make all the mainCR Active when ever the Sub is Active.
How ?
In this case in the first table when ever the MainCR is null then the CRNO is the MAINCR and the other thing when ever the CRNO is active the mainCR need to be active as well even if it is not active in this case
555 should be active because 5647 is active and 768 should be active as well
Second step :
I need to create table which includes mainCR with all other CR with it and Including all the status for these CR and Join it with the IDENTIFICATIONS table to add the ID because at the end I need to get the ID status with all CR including with this ID
The result at the end I want it to be something similar to this:
partner| main CR | Sub CR | Sub CR2 | Sub CR3 | Status
--------|---------|------------------------------
23453 | 555 | 5647 | 7845 | 8668 | Act-not Act -can -Act
23555 | 434 | 566 | Null | Null | Act - Act
26653 | 768 | Null | Null | Null | Can
I tried a lot of queries but with no luck I need ur help in this one
I am fine to have status in different columns as long as these are in the same row

I'm trying to join the two table and at the same time getting the value of the certain column by using inner join, I tried joining until the 3rd diagram but when it comes to the fourth it doesn't display the null values, how can I display the values of the 4th column even the null values
here's the code of the SQL
betl.user_id,
betl.agent_id,
ah1.parent_id,
ah2.user_id,
ah3.user_id AS parent_of_agent
FROM
wpc16_02.bets_logs betl
INNER JOIN
wpc16_02.agent_heirarchy ah1 ON betl.agent_id = ah1.user_id
INNER JOIN
wpc16_02.agent_heirarchy ah2 ON ah1.parent_id = ah2.id
INNER JOIN
wpc16_02.agent_heirarchy ah3 ON ah2.parent_id = ah3.id
WHERE
fight_id = 1930 AND agent_income = 0
here's what I'm trying to achieve by using innerjoins:
Here's the result I got when trying the joining upto the 3rd diagram:
user_id | agent_id | parent_id | user_id_of_parent
15012 | 2212 | 96 | 160
227097 | 22061 | 266 | 64
465174 | 464899 | 126 | 211
505094 | 504767 | 980 | 5358
241158 | 8281 | 18 | 67
463344 | 462715 | 751 | 3420
184396 | 29870 | 502 | 2123
486847 | 43225 | 164 | 234
482120 | 482023 | 4430 | 46469
369628 | 217212 | 8283 | 109697
When joining upto 4th diagram:
user_id | agent_id | parent_id | user_id_of_parent | master_uid
184396 | 29870 | 502 | 2123 | 160
482120 | 482023 | 4430 | 46469 | 699
369628 | 217212 | 8283 | 109697 | 71
97287 | 93996 | 7332 | 93866 | 3114
113287 | 113228 | 2714 | 20652 | 4050
366287 | 361918 | 17603 | 235880 | 234
439935 | 236147 | 3776 | 40054 | 103
480201 | 436936 | 1041 | 5761 | 160
456400 | 456248 | 32901 | 431900 | 240
502877 | 497592 | 2571 | 20845 | 3918
notice the other datas have been removed because when I joined the 4th diagram some of the results are null
You seem to want LEFT JOIN. It is a little unclear what the exact query is, because your question doesn't have information such as which columns are in which tables.
But the idea is:
SELECT . . .
FROM wpc16_02.bets_logs betl LEFT JOIN
wpc16_02.agent_heirarchy ah1
ON betl.agent_id = ah1.user_id LEFT JOIN
wpc16_02.agent_heirarchy ah2
ON ah1.parent_id = ah2.id LEFT JOIN
wpc16_02.agent_heirarchy ah3
ON ah2.parent_id = ah3.id
WHERE betl.fight_id = 1930 AND betl.agent_income = 0
This assums that flight_id and agent_income are from the first table. If they are in one of the hierarchy tables, then the conditions should go in the appropriate ON clause.
I have three different tables here:
df_umts_relation table:
|---------------------|------------------|---------------------|------------------|------------------|
| cell_name | n_cell_name | technology | source_ops_num | target_ops_num |
|---------------------|------------------|---------------------|------------------|------------------|
| 121 | 221 | UMTS | 1 | | |
|---------------------|------------------|---------------------|------------------|------------------|
| 122 | 222 | GSM | 2 | | |
|---------------------|------------------|---------------------|------------------|------------------|
| 123 | 223 | UMTS | 3 | | |
|---------------------|------------------|---------------------|------------------|------------------|
| 124 | 224 | GSM | 4 | | |
|---------------------|------------------|---------------------|------------------|------------------|
| 125 | 225 | GSM | 5 | | |
|---------------------|------------------|---------------------|------------------|------------------|
| 126 | 226 | UMTS | 6 | | |
|---------------------|------------------|---------------------|------------------|------------------|
| 127 | 227 | UMTS | 7 | | |
|---------------------|------------------|---------------------|------------------|------------------|
So now I want to update target_ops_num from the two below tables
df_umts_carrier table as this table contains those thow columns I want to work on them and contains some integer values also:
|---------------------|------------------|
| opsnum_umts | cell_name_umts |
|---------------------|------------------|
as I have another table called df_gsm_carrier:
|---------------------|------------------|
| opsnum_gsm | cellname |
|---------------------|------------------|
So All I need I want to update [MyNewDatabase].[dbo].[df_umts_relation].[target_ops_num] CASE WHEN technologyis UMTS then update from table df_umts_carrier ELSE technology is GSM then update from df_gsm_carrier on n_cell_name = cell_name_umts and on n_cell_name = cellname
So I tried to create a query as the below one works with one condition only and it's update the the rows which is UMTS only:
UPDATE [MyNewDatabase].[dbo].[df_umts_relation]
SET [MyNewDatabase].[dbo].[df_umts_relation].[target_ops_num] = [MyNewDatabase].[dbo].[df_umts_carrier].[opsnum_umts]
FROM [MyNewDatabase].[dbo].[df_umts_relation]
INNER JOIN [MyNewDatabase].[dbo].[df_umts_carrier]
ON [n_cell_name] = [cell_name_umts]
and works fine but doesn't update the rows which contains GSM...
On other way I tried to create a query to handle this but it didn't update the GSM part and take a long of time:
UPDATE [MyNewDatabase].[dbo].[df_umts_relation]
SET [MyNewDatabase].[dbo].[df_umts_relation].[target_ops_num] = (CASE WHEN [MyNewDatabase].[dbo].[df_umts_relation].[technology] = 'UMTS'
THEN [MyNewDatabase].[dbo].[df_umts_carrier].[opsnum_umts] ELSE [MyNewDatabase].[dbo].[df_gsm_carrier].[opsnum_gsm] END)
FROM [MyNewDatabase].[dbo].[df_umts_relation]
LEFT JOIN [MyNewDatabase].[dbo].[df_umts_carrier]
ON [n_cell_name] = [cell_name_umts]
LEFT JOIN [MyNewDatabase].[dbo].[df_gsm_carrier]
ON [n_cell_name] = [cell_name]
So any one have any idea how to solve this?
Please check if this will help.
update df_umts_relation
set target_ops_num = ( select case when dur.technology = 'UMTS' then du.cell_name_umts
when dur.technology = 'GSM' then dg.cellname
end
from df_umts_relation dur
left join df_umts_carrier du on dur.n_cell_name = du.opsnum_umts
left join df_gsm_carrier dg on dur.n_cell_name = dg.opsnum_umts
where dur.id= df_umts_relation.id)
Here is a demo
I am new to working with databases and I want to make sure I understand the best way to add or remove data from a database without making a mess of any related data.
Here is a scenario I am working with:
I have a Tags table, with an Identity ID column. The Tags can be selected via the web application to categorize stories that are submitted by a user. When the database was first seeded; like tags were seeded in order together. As you can see all the Campuses (cities) were 1-4, the Colleges (subjects) are 5-7, and Populations are 8-11.
If this database is live in production and the client wants to add a new Campus (City) tag, what is the best way to do this?
All the other city tags are sort of organized at the top, it seems like the only option is to insert any new tags at to bottom of the table, where they will end up taking whatever the next ID available is. I suppose this is fine because the Display category column will allow us to know which categories these new tags actually belong to.
Is this typical? Is there better ways to set up the database or handle this situation such that everything remains more organized?
Thank you
+----+------------------+---------------+-----------------+--------------+--------+----------+
| ID | DisplayName | DisplayDetail | DisplayCategory | DisplayOrder | Active | ParentID |
+----+------------------+---------------+-----------------+--------------+--------+----------+
| 1 | Albany | NULL | 1 | 0 | 1 | NULL |
| 2 | Buffalo | NULL | 1 | 1 | 1 | NULL |
| 3 | New York City | NULL | 1 | 2 | 1 | NULL |
| 4 | Syracuse | NULL | 1 | 3 | 1 | NULL |
| 5 | Business | NULL | 2 | 0 | 1 | NULL |
| 6 | Dentistry | NULL | 2 | 1 | 1 | NULL |
| 7 | Law | NULL | 2 | 2 | 1 | NULL |
| 8 | Student-Athletes | NULL | 3 | 0 | 1 | NULL |
| 9 | Alumni | NULL | 3 | 1 | 1 | NULL |
| 10 | Faculty | NULL | 3 | 2 | 1 | NULL |
| 11 | Staff | NULL | 3 | 3 | 1 | NULL |
+----+------------------+---------------+-----------------+--------------+--------+----------+
The terms "top" and "bottom" which you use aren't really applicable. "Albany" isn't at the "Top" of the table - it's merely at the top of the specific view you see when you query the table without specifying a meaningful sort order. It defaults to a sort order based on the Id or an internal ROWID parameter, which isn't the logical way to show this data.
Data in the table isn't inherently ordered. If you want to view your tags organized by their category, simply order your query by DisplayCategory (and probably by DisplayOrder afterwards), and you'll see your data properly organized. You can even create a persistent View that sorts it that way for your convenience.
I have a database table that has a companion many-to-many self-join table alongside it. The primary table is part and the other table is alternate_part (basically, alternate parts are identical to their main part with different #s). Every record in the alternate_part table is also in the part table. To illustrate:
`part`
| part_id | part_number | description |
|---------|-------------|-------------|
| 1 | 00001 | wheel |
| 2 | 00002 | tire |
| 3 | 00003 | window |
| 4 | 00004 | seat |
| 5 | 00005 | wheel |
| 6 | 00006 | tire |
| 7 | 00007 | window |
| 8 | 00008 | seat |
| 9 | 00009 | wheel |
| 10 | 00010 | tire |
| 11 | 00011 | window |
| 12 | 00012 | seat |
`alternate_part`
| main_part_id | alt_part_id |
|--------------|-------------|
| 1 | 5 | // Wheel
| 5 | 1 | // |
| 5 | 9 | // |
| 9 | 5 | // |
| 2 | 6 | // Tire
| 6 | 2 | // |
| ... | ... | // |
I am trying to produce a simple SQL query that will give me a list of all alternates for a main part. The tricky part is: some alternates are only listed as alternates of alternates, it is not guaranteed that every viable alternate for a part is listed as a direct alternate. e.g., if 'Part 3' is an alternate of 'Part 2' which is an alternate of 'Part 1', then Part 3 is an alternate of Part 1 (even if the alternate_part table doesn't list a direct link). The reverse is also true (Part 1 is an alternate of Part 3).
Basically, right now I'm pulling alternates and iterating through them
SELECT p.*, ap.*
FROM part p
INNER JOIN alternate_part ap ON p.part_id = ap.main_part_id
And then going back and doing the same again on those alternates. But, I think there's got to be a better way.
The SQL query I'm looking for will basically give me:
| part_id | alt_part_id |
|---------|-------------|
| 1 | 5 |
| 1 | 9 |
For part_id = 1, even when 1 & 9 are not explicitly linked in the alternates table.
Note: I have no control whatever over the structure of the DB, it is a distributed software solution.
Note 2: It is an Oracle platform, if that affects syntax.
You have to create hierarchical tree , probably you have to use connect by prior , nocycle query
something like this
select distinct p.part_id,p.part_number,p.description,c.main_part_id
from part p
left join (
select main_part_id,connect_by_root(main_part_id) real_part_id
from alternate_part
connect by NOCYCLE prior main_part_id = alternate_part_id
) c
on p.part_id = c.real_part_id and p.part_id != c.main_part_id
order by p.part_id
You can read full documentation about Hierarchical queries at http://docs.oracle.com/cd/B28359_01/server.111/b28286/queries003.htm
Sorry for the title, perhaps it's not very clear.
I have some SQL queries in a script that depend on each other.
The script uses a temporary table in which the data is inserted (the #temp_data table).
This is the expected output:
___________________________________
| speed1 | speed2 | distance |
| 1 | NULL | 10 |
| 3 | NULL | 40 |
| 5 | NULL | 90 |
| NULL | 1 | 10 |
| NULL | 3 | 40 |
| NULL | 5 | 90 |
Here is the query structure (I didn't include the actual query since it's too big):
-- First group
queryForSpeed1
queryToUpdateDistanceBasedOnSpeed1
-- Second group
queryForSpeed2
queryToUpdateDistanceBasedOnSpeed2
If I run the first group of queries (queryForSpeed1 and queryToUpdateDistanceBasedOnSpeed1) separately from the second group then I get the expected output: only the speed1 and distance columns contain data:
___________________________________
| speed1 | speed2 | distance |
| 1 | NULL | 10 |
| 3 | NULL | 40 |
| 5 | NULL | 90 |
| NULL | NULL | NULL |
| NULL | NULL | NULL |
| NULL | NULL | NULL |
The same happens when I run the second group:
___________________________________
| speed1 | speed2 | distance |
| NULL | NULL | NULL |
| NULL | NULL | NULL |
| NULL | NULL | NULL |
| NULL | 1 | 10 |
| NULL | 2 | 40 |
| NULL | 3 | 90 |
BUT, when I run both groups: all the distances are NULL:
___________________________________
| speed1 | speed2 | distance |
| 1 | NULL | NULL |
| 3 | NULL | NULL |
| 5 | NULL | NULL |
| NULL | 1 | NULL |
| NULL | 2 | NULL |
| NULL | 3 | NULL |
I believe this is somehow related to transaction management and temporary tables, although I wasn't able to find anything relevant to solve the problem on Google.
From what I've read, SQL Server keeps a transaction log where it stores every update, insert and whatever... when it arrives at the end of the script it actually does all those insertions and updates.
So the update I did for the distance column finds all the speeds as being NULL because the data wasn't yet inserted in the temporary table from the previous updates, but at the end of the query the speeds are inserted in the table so that's why they are visible.
I played a bit with the GO statement to execute my script in batches, but no luck so far...
What am I doing wrong? Can someone point me in the right direction, please?
EDIT
Here is the actual query.
The problem is not related to transactions, but rather to the way you conduct updates to #temp_speed_profile. The second pass through #temp_speed_profile retrieves all six records. Speed_new is null in first record of Voyage_Id, consequently #distance becomes null. As you retain the value of #distance in next turn, it remains null.
Problem goes away when using different temporary tables because second pass works on second set of data only.
A note on cursors - when defining one make sure to add local and fast_forward. Local because it is limiting cursors' scope, and fast_forward to optimize fetches.
It is almost certainly caused by the way you have written your queries.
To confirm, just rewrite your queries using #temp_data1 and #temp_data2, rather than a single table #temp_data.
