How to return the result set of multiple select statements as one result set?

Hi All,
I have multiple select statements in my stored procedure that I want to return as one result set
for instance
select id from tableA
union
select name from table b
but union will not work because the result sets datatypes are not identical so how to go about this ?
Thanks

You have to CAST or CONVERT (or implicitly convert) the columns to the same datatype. You must find a datatype that both columns can be converted to without error. In your example I'm guessing id is an int and name is a varchar or nvarchar.
Since you didn't convert the datatypes, SQL will use its data precedence rules and attempt to convert name to an int. If any row contains a row that has a value in name that cannot be converted to an int, you will get an error. The solution is
to force SQL to convert the int to varchar. So you want something like
select cast(id as varchar(12)) from tableA
union
select name from tableb
If the datatypes are something other that int or varchar, you must find a compatable datatype and then convert one (or both) of the columns to that datatype.

How to Return the Index of a Mouse-Selected Array Element in the View Interface of Diadem

Hello,
Does anybody have an idea of how to obtain the index of a mouse-selected array element in the View interface of Diadem??
Thanks!

Hi Ovidius,
Keep explaining. The only way I know of to trap a selected cell value in VIEW is to embed into the desired VIEW area a second non-modal SUDialog that has a Table control or an XTable control displaying the values of certain data channels. There are callbacks in both table controls for cell selection, and you can configure the table control to allow only single cell selection if that's what you want. The regular table control will be easier to program, but the XTable control will perform much better for larger channels.
But what happens with that value the user selected? Is it used for a calculation? Is it added to a report? Why would the user select that cell in a table rather than selecting the corresponding feature in a graph with the crosshair cursor?

Why does getdate() function return same time value for multiple select statements executed sequentially

When I run the following code
set nocount on
declare @i table(id int identity(1,1) primary key, sDate datetime)
while((select count(*) from @i)<10000)
begin
insert into @i(sDate) select getdate()
end
select top 5 sDate, count(id) selectCalls
from @i
group by sDate
order by count(id) desc
I get the following results.
sDate selectCalls
2014-07-30 14:50:27.510 406
2014-07-30 14:50:27.527 274
2014-07-30 14:50:27.540 219
2014-07-30 14:50:27.557 195
2014-07-30 14:50:27.573 170
As you can see the select getdate() function returned same time up to the milisecon 406 time for the first date value. This started happening when we moved our applications to a faster server with four processors. Is this correct or am I
going crazy?
Please let me know
Bilal

Observe that adding 2 ms is accurate only with datetime2. As noted above, datetime does not have ms resolution:
set nocount on
declare @d datetime, @i int, @d2 datetime2
select @d = getdate(), @i = 0, @d2 = sysdatetime()
while(@i<10)
begin
select @d2, @d, current_timestamp, getdate(), sysdatetime()
select @d = dateadd(ms,2,@d), @i = @i+1, @d2=dateadd(ms,2,@d2)
end

Can we give multiple select statements in one function in PL/SQL

Hi All,
I am new to the PL/SQL. Can you please help me with the following problem.
I am cretaing a function in which I have to extract some fields from three tables and to handle three tables I am first extracting the primary key from one table(acting as a foreign key for other table) in a variable declared in declare section, then I am selecting the required fields from the other table by giving that variable name in Where condition. My code is attached as well.
e.g
Create or Replace function <function name>(arguments)
Return return type
AS
a1 a%TYPE;
b_new b%TYPE;
n fn%TYPE
Select a into a1 from table1 where b like b_new;
Select fn into n from table2 where id like a1;
return a1,n; (can we pass record like this?)
end;

Left's first look at the approach you use.. 2 SQL statements that can be done using a single SQL statement.
Actually it is not as bad as some other code posted here where people go and write complex PL/SQL code to do what could have been done using a single SQL statement.
There are a couple of golden rules in Oracle development. One of these is to 'Maximise SQL and Minimise PL/SQL'.
Why take a value from one SQL statement into PL/SQL and then use that value in a second SQL statement?
Rather do this:
select
fn into n
from table2
where id like (Select a from table1 where b like b_new);Also keep in mind that in PL/SQL the above SQL construct is only able to fetch a single row - look at the bold above. The variable N can only hold a single value. If that SQL SELECT returns more than one value, how is variable N suppose to hold it?
I suggest that you read [url http://www.oracle.com/pls/db102/to_toc?pathname=appdev.102%2Fb14261%2Ftoc.htm&remark=portal+%28Books%29]Oracle® Database PL/SQL User's Guide and Reference guide.

Values from a Multi-Select in the where clause of a Select statement

I have a web page that solicits query parameters from the user.
The selections that the user makes will populate the WHERE clause of a Select statement.
One of the controls on the page is a multi-select control.
When this page posts, I would like to execute a Select statement wherein the selected values from this control appear in the .. Column IN ( <list here> ) portion of the WHERE clause.
This is an extremely common scenario, but I cannot seem to locate a how-to or message thread that addresses this specific case.
I have an idea that it may involve dynamic SQL or Execute Immediate, but cannot seem to pin down the answer.
Any help would be greatly appreciated!

How to add a dummy row in the result set of a SELECT statement.

Hello Everyone -
I have requirment to add a dummy row in the result set of a SELECT statement.
For e.g. lets say there is a table Payment having following colums:
Payment_id number
status varchar2(10)
amount number
payment_date date
so here is the data :-
Payment_id Status Amount payment_date
1 Applied 100 12/07/2008
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
Here is my SQL
Select * form payment where payment_date >= 01/01/2009
Output will be
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
My desired output is below
2 Reversed 200 01/ 06/2009
3 Applied 300 01/ 07/2009
2 Reversed -200 01/ 06/2009 ------(Dummy Row)
Thrid row here is the dummy row which I want to add when status is "Reversed"
I would be very thankful for any kind of help in this regard ...
Thanks,
Gaurav

Cartesion joining against a dummy table is a useful method of creating a dummy row:
with my_tab as (select 1 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all
                select 1 cust_id, 2 Payment_id, 'Reversed' Status, 200 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 1 cust_id, 3 Payment_id, 'Applied' Status, 300 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 2 Payment_id, 'Reversed' Status, 200 Amount, to_date('01/05/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 3 Payment_id, 'Applied' Status, 300 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 4 Payment_id, 'Reversed' Status, -400 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                select 2 cust_id, 5 Payment_id, 'Applied' Status, 500 Amount, to_date('01/07/2009', 'mm/dd/yyyy') payment_date from dual),
                --- end of mimicking your table
      dummy as (select 'Reversed' col1, 1 rn from dual union all
                select 'Reversed' col1, 2 rn from dual)
select mt.cust_id,

NB. You may have to mess around with the ordering if that's not come back in the order you wanted. You didn't mention what the rules were for any expected ordering though, so I've made up my own *{;-)
Also, I added an identifier (cust_id) to differentiate between different sets of payments, since that's usually the case. Remove that if it's not applicable for your case.

How to return the name (or ID) of the Task FLow in Script

Sitaution; two task flows created which can be accessed via Tools > TaskFlows within FDQM
Task Flow "1.1 Multi Load - Import" --> Should run Batch Process Up to Import (enmBatchProcessLevel: 2)
Task Flow "2.1 Multi Load - Import Up To Validate" --> Should run Batch Process Up to Validate (enmBatchProcessLevel: 4)
I have developed one generic script which I would like to use for each task flow.
Only the enmBatchProcessLevel differs between the task flows and therefore I would like to parse this enmBatchProcessLevel as a parameter my generic script.
To be able to do this, the script needs to know on which task flow a user has clicked. So, I am looking for a function or statement which returns the name (or ID) of the task flow. Based on this name (or ID) a conditional statement can be performed in which a variable is dynamically filled. This variable can then be parsed as a parameter to my generic script.
For instance:
Sub GenericRoutine
     Dim strTaskFlow
     Dim intBatchProcessLevel
     '--Get the Task Flow Name
     strTaskFlow = ......<How to return the TaskFlow name or ID?>
     '--Validate the task flow and fill variable intBatchProcessLevel dynamically
     Select Case strTaskFlow
          Case "1.1 Multi Load - Import"
               intBatchProcessLevel = 2
          Case "2.1 Multi Load - Import Up To Validate"
               intBatchProcessLevel = 4
     End Select
     '--Execute generic script
     '--Call Batch script and parse intBatchProcessLevel as a parameter:
     Call sBatchProcess(intBatchProcessLevel)
     '--Execute generic script
End Sub
Sub sBatchProcess(Byval intBatchProcessLevel)
     Dim lngProcessLevel
     Dim strDelimiter
     Dim blnAutoMapCorrect
     '--Use intBatchProcessLevel to fill lngProcessLevel
     lngProcessLevel = intBatchProcessLevel
     strDelimiter = "_"
     blnAutoMapCorrect = 0
     Set BATCHENG.PcolFiles = BATCHENG.fFileCollectionCreate(CStr(strDelimiter))
     BATCHENG.mFileCollectionProcess BATCHENG.PcolFiles, CLng(lngProcessLevel), , CBool(blnAutoMapCorrect)
End Sub

Hi, thanks for your reply.
The Generic script contains 600+ records, which I would like to maintain once, when having multiple Task Flows for Import, UpToValidate, ValidateOnly, UpToExport, ExportOnly etc.
Is there a central storage in FDQM workbench for script, like a "Module" in Excel VisualBasic environment? Thanks!

Ever since I updated my OS, the screen on my Mac will automatically become huge if I keep my mouse on the screen. I can't figure out how to return the screen to a normal size. Any help?

Hold down the 'ctrl' key and scroll backwards on the mouse.
Then go to System Preferences > Universal Access > Seeing. Turn off the Zoom feature.
Similarly in Sys Pref > Mouse uncheck the box for 'Zoom using scroll wheel…'
If it still occurs after that there may be a corrupt .plist file.
