Union two queries

i have two queries.
query 1: select to_char(date) as column1from table1
query 2: select getVarchar(somevalue) as column1 from table2
first query converts date to varchar2 and displays the column as column1
second query returns varchar2 and displays the column as column1
i want to union two queries
i am getting error while i do that.
error is 'expression must have same datatype as corresponding expression.
Solution?

things are working gud. my question is wrong

Combining two queries to one

I have two queries and I would like to output the results as
one and sort by Name ASC
Any help would be great thanks

Either use union in your SQL query or use Coldfusion to
combine exisitng queries and create a new query resultset.
Something like this:
<CFQUERY NAME="getDetailsQuery1"
DATASOURCE="#DSNNAME#">
SELECT * FROM getDetailsA
</CFQUERY>
<CFQUERY NAME="getDetailsQuery2"
DATASOURCE="#DSNNAME#">
SELECT * FROM getDetailsB
</CFQUERY>
<CFQUERY NAME="getDetails" DBTYPE="query">
SELECT * FROM getDetailsQuery1
UNION
SELECT * FROM getDetailsQuery2
ORDER BY Name ASC
</CFQUERY>
Hope this helps!
Cheers / Manu.

I have following two queries. How I can convert these two queries into one with the same result ?
Q1
SELECT id,vdate,vendorname,venddate,vid
FROM VENDOR
WHERE processid=32
AND venddate is null
AND vid in(select vid from view_vid where type='PDX')
AND (id,vdate) not in (select id,vdate from vkfl_is where task_id=55)
AND (id,vdate) in (select id,vidate from market_data where marketed_date is null)
AND id not in (select id from location)
Q2
SELECT id,vdate,vendorname,venddate,vid
FROM VENDOR

AND venddate is null
AND vid in(select vid from view_vid where type='PBX')

AND (id,vdate) in (select id,vidate from market_data where region_date is null)
AND id not in (select id from location)
I can UNION these two queries, but, is there any way I can write a single query with which gives me same result as above two queries?
Any help would be highly appreciated
Thanks in advance

Hi,
You can do something like this, which will be more efficient than a UNION:
SELECT id, vdate, vendorname, venddate, vid
FROM vendor
WHERE (   (    -- Conditions that apply only to q1
                           processid = 32
            AND vid       IN (SELECT vid FROM view_vid WHERE type = 'PDX')
            AND (id,vdate) NOT IN ( SELECT id, vdate
                                    FROM   vkfl_is
                                    WHERE task_id = 55
            AND (id,vdate) IN ( SELECT id, vidate
                                FROM   market_data
                                WHERE marketed_date IS NULL
        OR ( -- Conditions that apply only to q2
                 processid = 20
            AND vid       IN (SELECT vid FROM view_vid WHERE type = 'PBX')
            AND (id,vdate) NOT IN ( SELECT id, vdate
                                    FROM   vkfl_is
                                    WHERE task_id = 40
            AND (id,vdate) IN ( SELECT id, vidate
                                FROM market_data
                                WHERE region_date IS NULL
               -- The remaining conditions apply to both q1 and q2
AND     venddate   IS NULL
AND     id         NOT IN (SELECT id FROM location)
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.

Union two tables with diffrent count of fields with null and float value

Hello,
i want to union two tables, first one with 3 fields and second one with 4 fields (diffrent count of fields).
I can add null value at end of first select but it does not work with float values in second table. Value form second table is convert to integer.
For example:
select null v1 from sessions
union
select 0.05 v1 from sessions
result is set of null and 0 value.
As workaround i can type:
select null+0.0 v1 from sessions
union
select 0.05 v1 from sessions
or simple change select's order.
Is any better/proper way to do this? Can I somehow set float field type in first select?
Best regards,
Lukasz.
WIN XP, MAXDB 7.6.03

Hi Lukasz,
in a UNION statement the first statement defines the structure (number, names and types of fields) of the resultset.
Therefore you have to define a FLOAT field in the first SELECT statement in order to avoid conversion to VARCHAR.
Be aware that NULL and 0.0 are not the same thus NULL+0.0 does not equal NULL.
In fact NULL cannot equal to any number or character value at all.
BTW: you may want to use UNION ALL to avoid the search and removal of duplicates - looks like your datasets won't contain duplicates anyhow...

Merging two Queries in single crystal report lauout

Hi All,
I need to show two reports from two different BEx queries in a single crystal report layout. The queries are independent of each onther and having their selection variables. I have implemented two subreports for two queries in a main report. Now the problem i am facing is, though both the queries are having same slection(Profit Centre and Fiscal Per/Year), they are getting repeated in crystal report parameter screen. I have to enter the values for selections for each report.
Is there any method to merge the selections for both reports if they are same, so that i can enter the selections only once?
Thanks in Adv,
Shubhramukta.

Hi,
I have two queries in BEx having Selections. Query 1 is having selections (Profit centre and Fiscal Per/Yr) and query 2 is having same selections as well(i.e. Profit centre and Fiscal Per/Yr). I have created two reports corresponding to these queries have used as subreports in a main report using Crystal report 2008. When i run the main Crystal report, it automatically prompts for values to be entered, as variables are set at BEx query level.
Though both the reports are having same selection variables, crystal report asks to enter values two times , once for each report, and it is obvious.
Parameters are Crystal parameters.
Is there any method to merge the parameters,is selection variables are same, so that it will ask only once?
Thanks

Whats the difference between these two queries ? - for tuning purpose

Whats the difference between these two queries ?
I have huge amount of data for each table. its takeing such a long time (>5-6hrs).
here whice one is fast / do we have any other option there apart from listed here....
QUERY 1:
SELECT --<< USING INDEX >>
      field1, field2, field3, sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end)
    FROM
      tab1 inner join tab2 on condition1 inner join tab3 on condition2 inner join tab4 on conditon3
    WHERE
     condition4..10 and
    GROUP BY
      field1, field2,field3
    HAVING
      sum( case when field4 in (1,2) then 1 when field4 in (3,4) then -1 else 0 end) <> 0;
QUERY 2:
   SELECT --<< USING INDEX >>
      field1, field2, field3, sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0))
    FROM
      tab1, tab2, tab3, tab4
    WHERE
     condition1 and
     condition2 and
     condition3 and
     condition4..10
    GROUP BY
      field1, field2,field3
    HAVING
      sum( decode(field4, 1, 1, 2, 1, 3, -1, 4, -1 ,0)) <> 0;
[pre]

My feeling here is that simply changing join syntax and case vs decode issues is not going to give any significant improvement in performance, and as Tubby points out, there is not a lot to go on. I think you are going to have to investigate things along the line of parallel query and index vs full table scans as well any number of performance tuning methods before you will see any significant gains. I would start with the Performance Manual as a start and then follow that up with the hard yards of query plans and stats.
Alternatively, you could just set the gofast parameter to TRUE and everything will be all right.

How to Insert two queries in a single workbook in BI 7 ?

Hi,
I am trying to insert two queries in a single workbook. The queries are of Accounts Receivable.I have inserted one query in a workbook , but am not able to proceed to inserting the second query. In BEx analyzer, in design mode , using analysis grid , i tried inserting the second query but when saving and running, i am getting message " Variables are present, change their values " . should i maintain same variables for two queries ? i am stuck up. please explain me as how can this be done.
Roja.

Hi,
If you get the message "Variables are present, change their values" ,it means that the query which you inserted having variables.
You just click the "Change Variables" icon in the Analysis Toolbox,which will invoke the variable screen.
Set the values in the variable screen and click OK.
Now you will be able to see the data in the grids based on the values selected in the variable screen.
Both queries data will be displayed in the workbook.
Let me know in case of any clarifications!

Report with Two Queries -- Really need your Help Guys

I might be posting duplicate thread but i couldnt found the Q&A that i am looking for.
I am trying to create a report where i have to use two query. Also, with this query i am passing parameter where i ask user to enter Report Month so they can run report by what ever month they want to see data.
Now my Q_2 is duplicate or Q_1 because in my final report layout i have to display fields where i have to compare current_month_data to Previous_month_data. so basically i want user to in put current month date and previous month date and layout look like.
Company_Name Currentmonth_sale previousMonth_Sales ....
Honda $1423.42 $324.42
Toyota $3433 $4255.45
so on....
Now so far i create report manualy and drop two query in to the report but when i trying to create Report Wizard and group by each Company.. it is not giving me the out put that i want. Instead of giving me above out put its give me my Q_! result with each company group and then under that result i have Q_2 result.
so HOW CAN I DISPLAY FIELDS FROM MY Q_2 WITH MY REST OF THE FIELD ON Q_1?????????????????????????
Thank You guys.

Actually, I tried to use Data Link but i am not able to success.
Let me know if I am doing anything wrong . i click on left hand side tool panel where its says DATA LINK. then i click on Q_1 field and then drag the mouse over to Q_2 query with same field name. but its give me an error that Can not link it because of Group data and i have option to choose Yes, NO or Cancel.
Let me know what are the step i need to take in order to link this two queries.
Thank You

Confused on syntax-combine two queries

I have two queries that I'm trying to combine, but can't figure out how to combine them ... successfully!?! The first query is pretty simple in that I'm looking at several fields from two different tables, no big deal.
The second query calculates the years, months, days between two dates that are used in the first query. I'm stumped on how to combine the queries so that they place nice with each other and return results.
Here's the first query ...
select
RTRIM(RTRIM(vpi.LastName) + ', ' + RTRIM(ISNULL(vpi.FirstName,''))) Employee,
convert(varchar,vpi.FromEffectiveDate,101) PositionStart,
convert(varchar,vpi.ToEffectiveDate,101) PositionChange,
convert(varchar,vpi.PositionStartDate,101) PositionStartDate,
vpi.PositionReason, vpi.PositionCode, vpc.PositionCodeDescription
from vhrl_positioninfo vpi
inner join position_codes vpc on vpi.PositionCode = vpc.PositionCode
Here's the second query ...
select
[Age] = convert(varchar, [Years]) + ' Years ' +
          convert(varchar, [Months]) + ' Months ' +
          convert(varchar, [Days]) + ' Days',     *
from
     select
          [Years] = case     when BirthDayThisYear <= Today
                    then datediff(year, BirthYearStart, CurrYearStart)
                    else datediff(year, BirthYearStart, CurrYearStart) - 1
                    end,
          [Months]= case     when BirthDayThisYear <= Today
                    then datediff(month, BirthDayThisYear, Today)
                    else datediff(month, BirthDayThisYear, Today) + 12
                    end,
          [Days]= case     when BirthDayThisMonth <= Today
                    then datediff(day, BirthDayThisMonth, Today)
                    else datediff(day, dateadd(month, -1, BirthDayThisMonth), Today)
                    end,
          Birth = convert(varchar(10) ,Birth, 121),
          Today = convert(varchar(10), Today, 121)
     from
          select     BirthDayThisYear =
               case     when     day(dateadd(year, datediff(year, BirthYearStart, CurrYearStart), Birth)) <> day(Birth)
                    then     dateadd(day, 1, dateadd(year, datediff(year, BirthYearStart, CurrYearStart), Birth))
                    else     dateadd(year, datediff(year, BirthYearStart, CurrYearStart), Birth)
                    end,
               BirthDayThisMonth =
               case      when      day(dateadd(month, datediff(month, BirthMonthStart, CurrMonthStart), Birth)) <> day(Birth)
                    then     dateadd(day, 1, dateadd(month, datediff(month, BirthMonthStart, CurrMonthStart), Birth))
                    else     dateadd(month, datediff(month, BirthMonthStart, CurrMonthStart), Birth)

               from
                    select birth = convert(datetime, fromeffectivedate) ,
                    Today = case when convert(datetime, toeffectivedate) = '3000-01-01'

vpc table ...
PosCode PosDescription
OperPack Pack Line Operator

This is what the results should look like ...
John, Doe 2001-10-15 3000-01-01 10-15-2001 Transfer OperPack Pack Line Operator 6 Years 11 Months 16 Days
John, Doe 1994-11-28 2001-10-14 1994-11-28 New Hire OperDC Descaler Operator 6 Years 6 Months 19 Days
I know the date calculation piece adds 5 additional fields to the end, but they are not needed for the final report. Any help would be greatly appreciated! Thank you! Jena

Why are two queries better than one

I'm trying to help out our developers who are struggling with the performance of a very simple select statmenent that for some reason is exhibiting some very inexplicable results.
I'll show the SQL as a single statement first.....
select * from transaction1 t where t.hid in (select distinct h.hid from history1 h,filter1 f where h.fid = f.fid and f.match='value');
transaction 1 has 250k records, history1 has about 100k as does filter1. We know generally the subselect will only return a total of half a dozen or less records (only 1 in our testing here).
Running the above query takes around 7 seconds.
Changing this to a with clause.....
WITH a as (select distinct h.hid from history1 h,filter1 f where h.fid = f.fid and f.match='value') select * from transaction1 t where t,hid in (select a.hid from a);
and the runtime drops to 3 seconds. But then re-running the first statement again also now takes 3 seconds (so I guess there's some caching going on there).
Now what really puzzles is if we split this into two queries.....
select distinct h.hid from history1 h,filter1 f where h.fid = f.fid and f.match='value';
This takes .1 of a second,
select * from transaction1 t where t.hid in (12345);
And this takes .1 of a second.
So why when run seperately are they so fast, yet combined they take so long. I'm a bit baffled by this. We've rewritten the same SQL in half a dozen different ways with the same result and also done the same thing with other tables as well. Is it an optimisation issue?

Query works as two queries, but not as one

I am beating my head against the wall trying to figure out why a query will not return, yet when I break it up into two queries, they both return successfully.
There is a text index on the text_a field.
This is my query:
select distinct /*+ */ table_c.rec_id
from table_d, table_n, table_c
where ( ((create_date >='2006-03-16T00:00:00Z')
and (misc_field='abcd')
and (contains( text_a,'ABC or DEF or GHI or JKL or MNP') > 0 ))
/* and (rownum <=2000) */)
and table_c.rec_id = table_d.rec_id
and table_c.create_date = table_d.create_date
and table_c.rec_id = table_n.rec_id
and table_c.create_date = table_n.create_date
This query will not return data. I get an ora-1555 every time I let it run. The longest I let it run before getting the 1555 error was 1 hr and 50 min.
Tests suspecting a text data problem:
Now, here's what's puzzling. The query will run if 'JKL' is taken out. So, I thought this value may be the problem, so I ran the query with just the 'JKL' value in the "contains" clause and it did not return a value.
Tests suspecting a date problem:
Now, even more strange: When I ran the query (with all 5 conditions for misc_field) and looked from 2006-03-17T00:00:00Z, it returned records in less than 5 minutes. Then I queries just the 16th (create_date>='2006-03-16T00:00:00Z' and create_date < '2006-03-17T00:00:00Z' and it returned rows in less than 1 minute. So, I looked at the tokens for those dates, and there are values for all of them for each of the dates from the 16th to the present (the 21st). However, when I put them together in the query above, the query just seems to hang.
The total number of rows that should be returned is around 650 (adding the two results that worked).
Any suggestions? The indexes are valid, syncing is up-to-date, optimizing has no errors,a nd there are token_counts for the tokens in the $I table for the text_a field.
This problem has crossed into a second day and the same value of the 16th (as in the query above) is still used and still does not return rows. What else should I be looking at?
In advance, thanks for any suggestions/assistance.
- Jenny

I believe the 1555 error is an obscure response to (i.e. a result of) another problem.
The create_date column is a date datatype. The NLS format matches at the session, instance and database level (nls_session_parameters, and instance, and database). The NLS_DATE_FORMAT is set to YYYY-MM-DD"T"HH24:MI:SS"Z" in each of those views. Would this still cause a potential problem?
I neglected to say that we are on version 9.2.0.7 (both the data dictionary and the binaries).
The response from raford suggests that the optimizer is causing the text index to be called in "functional lookup" mode. I tried testing it, forcing it to use an index. The query ran in 3.5 minutes. Then I tested the original query and received the same results. After checking with the other DBAs, one of them was updating statistics on partitions for previous days' data. The statistics were only being run on current data partitions for the current day, but apparently the method that the application uses to "update" data (which could be for previous days) is to delete it and then insert it. I am suspecting that this is the root cause of all our evil! We are currently working with the developers to get this design changed. In the meantime, I REALLY appreciate all the help/suggestions. If we see the problem occur again, we will add the hint to test and verify whether or not that is the cause. I suspect it will be. Thank you raford.
Darn that optimizer!!!! ;-)
Oh, just a hint: Using set autotrace traceonly explain will NOT show that each of the text index partitions is being scanned. This was what we were using for our explain plans. But, when another query, with a similar problem, was finally run, we used EM and the "Long Ops" tab to finally see that each partition was being scanned for the token, whether it needed it or not. I think I'll go back to Tom Kyte's website and look for that article on the set autotrace traceonly explain not giving a totally accurate explain plan.
Thanks again.

Requirement wherein I want to call two queries in parallel using ABAP Prg

We are using RSCRM_BAPI to run a query in background and write the results to a table. We later read this table and create a file. I have a requirement u2013 wherein I want to call two queries in parallel using an ABAP program.
For our discussion assume:
1) Program : ZCALL_RCRMBAPI  is a program that calls RSCRM_BAPI in background and takes the query name as input
2) Program: ZMAIN_PROGRAM  this is the main program
The requirement is to call the ZCALL_RCRMBAPI in a loop. Also within the loop call it in parallel. Basically we have an ODS that stores ; FISCPER. So I call the two queries for a list of FISCPER.
ZMAIN_PROGRAM - A program that reads a table (ODS ) in our case and call the two programs in a loop and both should run in parallel .
Now if it was sequential u2013 it was easy u2013 I would just say
Loop at L_T_FISCPER .
Update Z_FISCPER with L_T_FISCPER-FISCPER u201C Assume Z_FISCPER is a Z table . The VARIABLE in the query Q1 and Q2 use a customer exit to read this table.
A)       SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q1 and return .
B)      SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q2 and return .
Endloop .
Question: How do I make these calls in parallel u2013 yet retain control in the main program?
A)       SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q1 and return .
B)      SUBMIT ZCALL_RCRMBAPI with P_QUERy = Q2 and return .

Instead of RSCRM BAPI you can use the RRW3_QUERY_VIEW_DATA function module for greater control over program execution...

How do I connect two Queries?

Hello all,
How do I connect two Queries and add some numbers.
Here is what I am trying to do.
Query 1: Gets G/L Credit Amounts for Jan 2007 Feb 2007 March 2007.....Dec 2007
Query 2: Gets G/L Debit Amounts for Jan 2007 Feb 2007 march 2007.....Dec 2007
I need to put both these Queries in a worksheet one below the other and add the totals by each month.....so the final report looks something like this:
I am using two structures to hold the query values.
G/L Credit Amount        Jan 2007    Feb 2007.............Dec 2007
                                    +100         +200                   +400
G/L Debit Amount           -50           -100                     -200
Total                              50             100                      200
Also, I would like to allow the users to enter Year as a variable. Any suggestions?
Your help is greatly appreciated.

Venkata,
Thanks for your reply. Could you explain how I insert two query results into one worksheet? And, also how do I link the two structures ( one structure per query) so I can total the amounts by each month?
Thank you in advance.

Two Queries in one Worksheet

Hi,
I'd like to know what the disadvantages are of having two queries in the same worksheet of a workbook. Is it correct that the results of one query can overflow to the area of the second? How about issues with authorization, are there any?
Thanks!

HI,
Yes, result of one can flow over the other if you are using simple report with characteristics and output may vary.
Actually you apply basic Excel logic and its like 2 diff report on it.
Mostly you add more Fixed format reports to a single sheet. So that number of report rows dont increase and also you dont have any free characteristics to drilldown.
About authorization, that depends on individual reports. If a user doesnt have proper authorization for 1 of the reports then that report would throw error while other would show result.
