SQL & PL/SQL :: From Clause With Conditions
Apr 2, 2013
You think i can do a from clause with conditions ??
The reason is that i need to retrieve fields from different schemas depending on a column in a common table
let s say the column CRITERIA_COL is in table Common
If COMMON.CRITERIA_COL has value 1 then the select query should fetch results from the schema : SCHEMA1.MY_TABLE
If COMMON.CRITERIA_COL has value 2 then the select query should fetch results from the schema : SCHEMA2.MY_TABLE
If COMMON.CRITERIA_COL has value 3 then the select query should fetch results from the schema : SCHEMA3.MY_TABLE
Something like this:
Select my_Col1, my_Col2 from
(case COMMON.CRITERIA
when '1' then SCHEMA1.MY_TABLE
when '2' then SCHEMA2.MY_TABLE
when '3' then SCHEMA3.MY_TABLE
)
but that is not working .By the way my query is not just that, it s a more complicated query, that s just the portion I am having trouble with .

I am trying to run an SQL query which refers/joins around 10 tables.In my case I would want to add an if-else or case condition in the WHERE clause of select query
For example
select a.column1, b.column1, c.column1, d.column1
from a, b, c, d
WHERE a.column2 = b.column2
AND (if a.column3 = 10 then ( I want 2 conditions to be
AND b.column2 = c.column2) added
else after WHERE clause as AND...)
AND b.column2 = d.column2
)
AND d.column2 = a.column2

I need to be clear about what exactly difference when we put any condition in INNER JOIN and WHERE Clause. I tried both way and found same results. Even in Statistics Plan not much differences.
1. Here I am using location filter in Inner join condition -
"SELECT I.*, Gl * From Sc1.Item I Inner Join Sc1.Part P On P.Part_Id = I.Part_Id Inner Join Sc1.Location Gl On Gl.Location_Id = I.Location_Id And Gl.Location_Id In ( 1767, 1747,202,1625) Inner Join Sc1.Condition C On C.Condtion_Id = Gl.Condition_Id Where I.Inactive_Ind = 0 And I.Condition_Id != 325
2. Here I am using location filter in Where clause
SELECT I.*, Gl * From Sc1.Item I Inner Join Sc1.Part P On P.Part_Id = I.Part_Id Inner Join Sc1.Location Gl On Gl.Location_Id = I.Location_Id Inner Join Sc1.Condition C On C.Condtion_Id = Gl.Condition_Id Where I.Inactive_Ind = 0 and I.LOCATION_ID in ( 1767, 1747,202,1625) And I.Condition_Id != 325.

I putted in a table "conditions" some rules (if conditions) and I want to read and execute those conditions in another table "list_parameters" in pl/sql procedure.
conditions :
ID||||||||||||||RULE
1-----------(param1 = F)
2-----------(param2 is null)
.....
list_parameters :
id_task|||||param1|||||param2|||||param3|||||param4
--x-----------F---------Z----------NULL-------NULL
--y----------- ---------A----------K-----------L

How can I use the conditions of clause IF from table "conditions"? Is it possible to do:
CURSOR cur_rules IS select * from conditions;
BEGIN
FOR c1_cur in cur_rules

I would like resolve an issue, I would like to know if is there any posibility to filter particular conditions using sql, the example that Im going to describe below shows these conditions:
create table t1
(
month number,
club char(2),
total_subs number
)
[Code]....
month sum(total_subs)
------------------------
1 21
2 13
3 89
4 6
5 7
therefore I would like exclude the total_subs for the club c2 in the months (1,2,3) and obtain the next result
month sum(total_subs)
-------------------------------
1 15
2 10
3 69
4 6
5 7

I am new to the forum as well as SQL programing and I need to have the following criteria writen in my WHERE so all three of these criterias are included in the same report (perhaps, each will have its own section).
1. PCT_To_Goal < 60
AND (round ( (opened_period / expected_Goal ), 2 ) * 100) >= 100
2. opened_period >= 3 and number_to_date = 0
3. PCT_To_Goal < 30
AND (round ( (opened_period / expected_Goal ), 2 ) * 100 > = 50
AND round ( (opened_period / expected_Goal ), 2 ) * 100 <= 100)

novice to SQL (Oracle 10g)
Am trying to write code for sollowing scenario:
Have 3 tables
table1 (campaignid,promoflag)
table2 (campaignid,projectid,campaigndesc)
table3 (projectid,promoflag,projectstart,projectend)
I am to update table 1 promoflag with value from promoflag in table3
Update table1
set promoflag = table3.promoflag
I would like to make sure only appropriate record is updated therefore want to use where clause condition but the primary key for table1 and table3 are different, the only link can be found on table2.
I want to use condition where table1.campaignid=table2.campaignid and table2.projectid=table1.projectid
Have used the following without success:
Scenario 1
Update table1
SET promoflag = table3.promoflag
FROM table1
inner join table2 on table1.campaignid = table2.camapaignid
inner join table3 on table2.projectid = table3.projectID;
Error at line 1 ORA-00933: SQL command not properly ended
Scenario 2 with real table/column names
Update UA_CAMPAIGNEXTATTR
SET CFPROMOTABLE = LMUK_PROJECT_AUDIENCE_GRID.GRID_AUD_CFPROMOTABLE
FROM UA_CAMPAIGNEXTATTR,UA_CAMPAIGN,LMUK_PROJECT_AUDIENCE_GRID
WHERE
UA_CAMPAIGNEXTATTR.CAMPAIGNID = UA_CAMPAIGN.CAMPAIGNID
AND UA_CAMPAIGN.PROJECTID = LMUK_PROJECT_AUDIENCE_GRID.GRID_AUDIENCE_ID;
Error at line 2
ORA-00933: SQL command not properly ended
It appears to get block with the 'FROM' statement (was underlined in red)

I've below table.
with tmp_tbl as
(select 'H1' as hh_id, 'C1' as cust_id, 2 as f_rnk, 'F' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100203','YYYYMMDD') first_dt from dual
union
select 'H1' as hh_id, 'C2' as cust_id, 1 as f_rnk, 'M' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100303','YYYYMMDD') first_dt from dual
union
select 'H1' as hh_id, 'C3' as cust_id, cast(null as number) as f_rnk, 'U' as gender, to_date('20130103','YYYYMMDD') as purch_dt,
[code].....
Now i need to rank each cust_id in each hh_id based on below conditions.
1) If atleaset one cust_id in hh_id has f_rnk then gender 'F' with highest f_rnk (more then one F with same f_rnk then the one with oldest first_dt), if no 'F' then gender 'U' with highest f_rnk ((more then one F with same f_rnk then the one with oldest first_dt)), if no 'F' and 'U' then consider 'M' (more then one M with same f_rnk then the one with oldest first_dt).
2) If the above is not met (no cust_id in hh_id has f_rnk populated) then i've to rank based on purch_dt. Gender 'F' with recent purch_dt (if more than one F in household with same purch_dt then the one with oldest first_dt), if no 'F' then gender 'U' with recent purch_dt (if more than one U in household with same purch_dt then one with oldest first_dt), if no 'F' and 'U' then consider 'M' (more than one M in household with same purch_dt then the one with oldest first_dt).
3) If the above criteria is also not met, then rank based on gender_cd. Gender 'F' will have first preference then 'U' and then 'M'.
My output :
HH_ID CUST_ID F_RNK GENDER PURCH_DT FIRST_DT F_RNK_RANK PURCH_RANK GENDER_ONLY_RANK
----- ------- ---------- ------ ----------- ----------- ------------ ------------ -----------------
H1 C1 2 F 1/2/2013 2/3/2010 1
H1 C2 1 M 1/2/2013 3/3/2010 2
H1 C3 U 1/3/2013 4/3/2010 3
H2 C4 F 4/3/2013 10/2/2009 2
H2 C5 M 5/5/2013 8/8/2010 1
H3 C6 F 5/6/2008 1
H3 C6 M 7/8/2010 2
I've tried below query with one condition, but it's giving f_rnk_rank for all records. How can i include multiple conditions in the rank function.
with tmp_tbl as
(select 'H1' as hh_id, 'C1' as cust_id, 2 as f_rnk, 'F' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100203','YYYYMMDD') first_dt from dual
union
select 'H1' as hh_id, 'C2' as cust_id, 1 as f_rnk, 'M' as gender, to_date('20130102','YYYYMMDD') as purch_dt, to_date('20100303','YYYYMMDD') first_dt from dual
union
select 'H1' as hh_id, 'C3' as cust_id, cast(null as number) as f_rnk, 'U' as gender, to_date('20130103','YYYYMMDD') as purch_dt, s hh_id, 'C5' as cust_id,

I am trying to use a CASE statement
CASE WHEN (EP.ORDER_NUMBER IS NOT NULL AND ATD.IS_DISCONNECT_CREDIT = 1 ) THEN
.........
......
END
In my case when I club two conditions after WHEN in case statement , everytime the first condtion is satisfied (i.e EP.ORDER_NUMBER IS NOT NULL) it is entering into the loop.
Irrespective of using AND or OR after the first condition I am getting the same results.
I want to enter the CASE statement only when both the conditions (1st and 2nd )are satisfied

While there's numerous QAs about inserting an image into the DB using the Data Block, how does one remove an image? Obviously there's the "UPDATE ... SET X = EMPTY_BLOB();", however, that kills the Data Block/Form's flow, and it doesn't update.
I've tried a few things:
* :CONTROL.IMG1 := NULL; (bad bind variable)
* :CONTROL.IMG1 := EMPTY_BLOB(); (some other error, probably as above)

Scenario 1 Query should check for priority record(25), if the start_date and end_date of that priority record is the max in that group, records will not have any split.output will be the same.
DC Store St Date End date Priority
955 3 1/1/2010 12/31/9999 25
966 3 4/5/2011 10/10/2011 50
977 3 10/12/2011 12/12/2012 100
output
DC store St Date End date Priority Rank
955 3 1/1/2010 12/31/9999 25 1
966 3 4/5/2011 10/10/2011 50 2
977 3 10/12/2011 12/12/2012 100 3
Scenario 2 If priority record is not covering the max range, then split the records as shown below,
1. during the time period 1/1/2011 & 4/30/2011 there were no other DC for that store so rank would be 1
2. the next range would be 5/1/2011 to 6/29/2011 we have 2 records in service so the record with low priortiy would be ranked 1 and second priority would be ranked 2
3. similarly, for 6/30/2011 to 10/1/2011 we have 3 records in service and it will be ranked accordingly on the priority.
DC Store St Date End date Priority
966 3 6/30/2011 10/1/2011 25
955 3 5/1/2011 11/30/2011 50
977 3 1/1/2011 12/31/2011 100
output
DC store St Date End date Priority Rank
977 3 1/1/2011 4/30/2011 100 1
955 3 5/1/2011 6/29/2011 50 1
977 3 5/1/2011 6/29/2011 100 2
[code]....
Scenario 3 This works similar to scenario 2
DC Store St Date End date Priority
966 3 2/1/2011 12/31/2011 25
955 3 1/1/2011 12/31/2012 50
977 3 5/1/2011 06/31/2011 100
output
DC store St Date End date Priority Rank
955 3 1/1/2011 1/31/2011 50 1
966 3 2/1/2011 12/31/2011 25 1
955 3 2/1/2011 12/31/2011 50 2
977 3 5/1/2011 6/30/2011 100 3
955 3 1/1/2012 12/31/2012 50 1
Note: Number of records in the input can vary and ther can be duplicates in the date interval

SUMMARY is my summarized table and COB is my reference table
Without adding condition in query it gives
INDEX (RANGE SCAN)--PK_SUMMARY(INDEX(UNIQUE))
After adding condition in query it gives
INDEX(FAST FULL SCAN)--PK_SUMMARY(INDEX(UNIQUE))
how can i keep RANGE SCAN even after adding my new conditions?
SELECT

I have a database block that refreshes using a timer. In short, I list all open work pieces for a certain garage, displaying route, run, on_time, of_time, location grouped by garage, on_time, off_time
I need to highlight every garage with a different color. I am highlighting the on_time every time the garage changes.
The problem is, every time I move down the records, instead of keeping the previous garage color, and highlight the new garage on_time with a new color, the whole on_time column will be set to the current garage color.
I need to break down the block by color so the user can distinguish between the different garages, and the start and end time. Here is my code, I am putting it in when_new_record_instance of the work_block:
IF :work_bLock.current_garage = 9006 THEN
Set_Item_Property('work_block.on_time', BACKGROUND_COLOR, 'r191g223b191');
ELSIF :work_bLock.current_garage = 9002 THEN
Set_Item_Property('work_block.on_time', BACKGROUND_COLOR, 'r255g228b196');
ELSE
Set_Item_Property('work_block.on_time', BACKGROUND_COLOR, 'r255g250b250');
END IF;
I need the block to be 3 or more different colors depending on the garage.

Actually I have one query which contains two parameters from_Date and To_date.
if user pass the values for the parameter like 1-dec-2010 to 30-dec-2010 query will works fine and it fetches the values according to the query selected. but now I am going to add one more parameter, the value is 01-apr-2010 now my query should run for 01-apr-2010 to 30-dec-2010.
Here my question is how should I make this scenario with only one query and at the same time the query should work for to scenarios.
