Hi I have above three select stetements, I have to merge those select statements into one select statements, all select statements having same conditions and filter conditions(in each select statement one filter condition different), I highlighted in the bold differencet filter conditions in each table, fianlly I should be get 7 coloumns like
LAST_UPDATE_DATE, COMMENTS, REASON, CORRECTD_ACTUAL_DELIVERY_DATE, LAST_UPDATE_DATE, CORRECTD_PROMISE_DATE, LAST_UPDATE_DATE
Please help on this
Thanks

Use CASE?
Possibly something like this:

Tuning is NOT about reducing the cost of i/o.
i/o is only one of many contributors to cost and only one of many contributors to waits.
Any time you would like to explore this further run this code:
SELECT 1 FROM dual
WHERE regexp_like(' ','^*[ ]*a');but not on a production box because you are going to experience an extreme tuning event with zero i/o.
And when I say "extreme" I mean "EXTREME!"
You've been warned.I think you just need a faster server.

I am not sure that this is a good example - the query either executes very fast, or never has a chance to start executing. But, it might still make your point physical I/O is not always the problem when performance problems are experienced.

We are getting multiple 8623 Errors in SQL Log while running Vendor's software.
How can you catch which Query causes the error?
I tried to catch it using SQL Profiler Trace but it doesn't show which Query/Sp is the one causing an error.
I also tried to use Extended Event session to catch it, but it doesn't create any output either.
Error:
The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that
reference a very large number of tables or partitions. Please simplify the query. If you believe you have received this message in error, contact Customer Support Services for more information.
Extended Event Session that I used;
CREATE EVENT SESSION
overly_complex_queries
ON SERVER
ADD EVENT sqlserver.error_reported
ACTION (sqlserver.sql_text, sqlserver.tsql_stack, sqlserver.database_id, sqlserver.username)
WHERE ([severity] = 16
AND [error_number] = 8623)
ADD TARGET package0.asynchronous_file_target
(SET filename = 'E:\SQLServer2012\MSSQL11.MSSQLSERVER\MSSQL\Log\XE\overly_complex_queries.xel' ,
metadatafile = 'E:\SQLServer2012\MSSQL11.MSSQLSERVER\MSSQL\Log\XE\overly_complex_queries.xem',
max_file_size = 10,
max_rollover_files = 5)
WITH (MAX_DISPATCH_LATENCY = 5SECONDS)
GO
-- Start the session
ALTER EVENT SESSION overly_complex_queries
ON SERVER STATE = START
GO
It creates only .xel file, but not .xem
Any help/advice is greatly appreciatedHi VK_DBA,
According to your error message, about which query statement may fail with error message 8623, as other post, you can use trace flag 4102 & 4118 for overcoming this error. Another way is looking for queries with very long IN lists, a large number of
UNIONs, or a large number of nested sub-queries. These are the most common causes of this particular error message.
The error 8623 occurs when attempting to select records through a query with a large number of entries in the "IN" clause (> 10,000). For avoiding this error, I suggest that you could apply the latest Cumulative Updates media for SQL Server 2012 Service
Pack 1, then simplify the query. You may try divide and conquer approach to get part of the query working (as temp table) and then add extra joins / conditions. Or You could try to run the query using the hint option (force order), option (hash join), option
(merge join) with a plan guide.
For more information about error 8623, you can review the following article.

Automatic Refresh of a Merged Power Query giving 'Table Not Registered' error
Scenario: I have 5 tables in my Azure VM SQL database associated with my ERP system. I have loaded all 5 tables into a 'Build Excel' workbook, merged the tables together and created a dataset that my users will be using. From that 'Build
Excel' workbook - I published to the BI catalog a data set simply called 'Customer information and Statistics' - This is searchable by my users and they don't have to go through the effort of combining the 5 tables.
I have a published workbook that uses the 'Customer Information and Statistics' data set and nothing else. I tried to schedule a refresh of the data and it failed (below is the error when I did a manual refresh):
OnPremise error: Sorry, the data source for this data connection isn't registered for Power BI. Ask your Power BI admin to register the data source in the Power BI admin center. An error occurred while processing table 'Customer Information and Statistics'.
The current operation was cancelled because another operation in the transaction failed.
So, going down that rabbit hole, I began the process of 'registering' this in Power BI - however, when I copied in the connection string it began walking me through a process of providing credentials to the 5 tables in my SQL server - that are already exposed
in my main data Sources. I figured I would continue and tried to use the service account credentials that my main data sources use and it would not properly authenticate.
Taking a step back it prompted a few questions:
Why am I being asked to register these 5 merged data sources that are already exposed in my base data sources?
Is my approach of creating 'Friendly named' Merged datasets for my users an incorrect approach?
Is there a different method I should be using to establish autorefresh on Merged datasets in these published workbooks using Power Query?
Thanks for the help -

I need help with the query
Here is what I need
For a particular comm record if there is no Salary record where comm:Date = Salary:Date, then
• Find maximum dated Salary record as of comm:Date.
• Clone this record and set Salary:Date = comm:Date
• Set Salary:rate = comm:rate
Like wise for a particular Salary record If there is no comm record where Salary:Date = comm:Date then
• Find maximum effective dated comm record as of Salary:Date
• Apply Rate 2 amount from this maximum effective dated record to Salary record i.e. Set Salary:rate = comm:rate
Example
Salary Table :
ID Sal_Date Rate Hours
1 07/01/2011 400.00 40
2 02/15/2011 200.00 40
3 01/01/2011 160.00 40
Sal_comm Table:
Sal_Date comm_Rate
1 07/01/2011 10.00
4 03/01/2011 7.50
3 01/01/2011 4.00
I need to merge comm_Rate column in Salary table, since there is no salary record as off 03/01/2011, I need to find the maximum dated salary record as of 03/01/2011
i.e. the record dated 02/15/2011. Now I need to clone that salary record, set the SAL_date as 03/01/2011 and update Rate2 amount. So the record set will be like:
Sal_Date:
id sal_Date Rate Hours comm_Rate
1 07/01/2011 400.00 40 10.00
4 03/01/2011 200.00 40 7.50
2 02/15/2011 200.00 40 4.00
3 01/01/2011 160.00 40 4.00So you need all used dates as the "driving" dataset. And you need the according data for each of these.
WITH salary_table as
(select 1 id,to_date('07/01/2011','MM/DD/YYYY')sal_date,400 rate,40 hours from dual union all
select 2 id,to_date('02/15/2011','MM/DD/YYYY')sal_date,200 rate,40 hours from dual union all
select 3 id,to_date('01/01/2011','MM/DD/YYYY')sal_date,160 rate,40 hours from dual),

select 3 id,to_date('01/01/2011','MM/DD/YYYY')sal_date,4 comm_Rate from dual)
select to_char(all_dates.sal_date,'MM/DD/YYYY') sal_date,sal.rate,sal.hours,com.comm_rate
from (select sal_date from salary_table
union
select sal_date from sal_comm) all_dates
inner join (select s1.*,lead(sal_date-1,1,to_date('31/12/9999','DD/MM/YYYY')) over (order by sal_date) next_sal_date

Need to merge the below two rows
Hi,
I have a sample data as shown below:
ID OBJID ACT_CODE ADDNL_INFO ENTRY_TIME
2523540 333003736 900 from WIP default to Queue PSD1. 1/3/2012 15:07
2523540 333003271 100 100 from Queue PSD1 to WIP For assigment. 1/3/2012 15:43
2523540 333003744 900 900 from WIP default to Queue PSD1. 1/3/2012 15:49
2523540 333004966 100 100 from Queue PSD1 to WIP For assigment. 1/3/2012 16:04
I need to merge the first two rows and get a single record for each "from" and "to" as shown below (desired output)
ID_NUMBER ADDNL_INFO ENTRY_TIME EXIT_TIME TOTAL TIME
2523540 PSD1 1/3/2012 15:07 1/3/2012 15:43 0.025069444
2523540 PSD1 1/3/2012 15:49 1/3/2012 16:04 0.010231481
I have used function on the addnl_info column to display only the name of the queue "PSD1"
(SUBSTR(ADDNL_INFO, INSTR(ADDNL_INFO, 'PSD1'), LENGTH('PSD1'))) QUEUE_NAME
Can any one help me out in getting the desired output.Below is a solution to your query:
drop table test_Table;
create table test_Table
ID number,
objid number,
act_code number,
addl_info varchar2(500),
entry_time timestamp
insert into test_Table values (2523540, 333003736, 900, 'from WIP default to Queue PSD1.', to_timestamp('1/3/2012 15:07', 'DD/MM/YYYY HH24:MI'));
insert into test_Table values (2523540, 333003271, 100, 'from Queue PSD1 to WIP For assigment.', to_timestamp('1/3/2012 15:43', 'DD/MM/YYYY HH24:MI'));
insert into test_Table values (2523540, 333003744, 900, 'from WIP default to Queue PSD1.', to_timestamp('1/3/2012 15:49', 'DD/MM/YYYY HH24:MI'));
insert into test_Table values (2523540, 333004966, 100, 'from Queue PSD1 to WIP For assigment.', to_timestamp('1/3/2012 16:04', 'DD/MM/YYYY HH24:MI'));
select * from test_table;
select id, addl_info, entry_time, exit_time, total_time
from
select a.id, a.objid, 'PSD1' addl_info, a.entry_time, lead(a.entry_time, 1, null) over (order by a.entry_time) exit_time,
lead(a.entry_time, 1, null) over (order by a.entry_time) - a.entry_time total_time, DECODE(a.act_code, 900, 'D', 'ND') disp
from test_Table a
where a.id = 2523540
where disp = 'D';
ID ADDL_INFO ENTRY_TIME EXIT_TIME TOTAL_TIME
2523540 PSD1 01-MAR-12 03.07.00.000000000 PM 01-MAR-12 03.43.00.000000000 PM 0 0:36:0.0
2523540 PSD1 01-MAR-12 03.49.00.000000000 PM 01-MAR-12 04.04.00.000000000 PM 0 0:15:0.0I see a shortcoming in the design:
1. For "WIP default to Queue PSD1" there are two records, both containing different OBJID but same ID, which in ideal case should not happen. You MUST have a COMPOSITE key on ID and OBJID; This shall help you to identify the distinct records.
My solution is not perfect as it is based on the ENTRY TIME. The reason being SIMPLE Ordering by the OBJID would not lead to a correct difference in the Transaction Time (referred by you as TOTAL_TIME.); Hence, for this reason I had to use ENTRY_TIME to correctly get the total_time.
If you wish you may follow the solution else I shall always recommend to change the Table Design and follow the correct approach.
If you are changing the Table design then following shall be a solution:
select id, addl_info, entry_time, exit_time, total_time
from
select a.id, a.objid, 'PSD1' addl_info, a.entry_time, lead(a.entry_time, 1, null) over (order by a.id, a.objid) exit_time,
lead(a.entry_time, 1, null) over (order by a.entry_time) - a.entry_time total_time, DECODE(a.act_code, 900, 'D', 'ND') disp
from test_Table a
where disp = 'D';Regards,

Hi,
I have created Credit Management workflow in CRM and now I am stuck with having the Credit Request Summary report. I tried Print preview, however it does not provide me the entire details. Under request, I have tabs such as Request details, Customer
details, Facility Details (multiple tables) and other securities details. Customer needs to have Print of Credit Request, to solve this I have created multiple reports which display the Facility details. But now I am stuck with merging those reports.
Need assistance....Hi ,
You can Merge the column by using Table Interface in WAD.What you can do is include the list of atendees(person) in the query and in Table interface you can have a lookup to the Infoprovider and get the corresponding value of list of atendees( company). Then you can concatenate both the value and diplay them under same column in WAD Report.
You can refer the below attached document for Table interface....

and shown below is the sample code how we are merging two columns in WAD report..
if I_X = 3.
MOVE C_CELL_CONTENT to CELL_DETAILS.
SEARCH CELL_DETAILS FOR '>'.
STARTING_OFFSET = SY-FDPOS + 1.
SEARCH CELL_DETAILS FOR '<' STARTING AT STARTING_OFFSET.
LENGTH = SY-FDPOS - 1.
MOVE CELL_DETAILS+STARTING_OFFSET(LENGTH) TO POSMDESC.
concatenate POSMDESC '<BR>' into POSMDESC.
read table itab_/BIC/TAPMPOSM into it_/BIC/TAPMPOSM with key
/BIC/APMPOSM = POSMID.
concatenate POSMDESC it_/BIC/TAPMPOSM-TXTLG into POSMDESC.
move POSMDESC to C_CELL_CONTENT.
endif.
Hope it helps....

Problems with putting the Schema on the query!!!! Need Help.
Hi guys!
I have a problem and a doubt about putting schema name on my query. I want to know if is neccesery specify the schema name on the query I want to execute. All my queries are on my application, I connect from the begging to my oracle data base with a user and password, this user is only alow for that schema. So my question is if I can ommit the schema name on the query.
Explample
Select * From Table
Select * from Student
Select * from Schema.Table
Select * from Institution.Student
Thanks, and I hope you can help me,

don't use words that you don't know!
also, your example (in the first post) gave the schema.table as INSTITUTION.STUDENT
so these are all words that you started with.
now, PAY ATTENTION and RUN THE EXAMPLE SQLS I GAVE
connect to the database as INSTITUTION (user, schema, I don't care which).
execute the sql statement "select * from student".
did it do anything? did it return data, did it say "no rows", or did it have an error? my magic 8 ball and x-ray glasses are broken and I can't see you monitor (my old computer only has that one way window). if it works, then you clearly do not need to put be "putting the Schema on the query!!!!". if it didn't work, then TELL US EXACTLY WHAT HAPPENED (copy AND paste).
and where are my cigars ;-)
MERGE AGAIN????? PLZ Somebody HELP ME!!!!! -
Is it possible to merge 2 query results?
I have a function that returns a querey result.
< CFSET temp = query1>
<CFSET FNCTransfers = temp>
Now I want to change the query to return a merged query
result
< CFSET temp = query1>
<CFSET temp2 = query2>
Is it possible to merge the two results?
Some thing like this (I know that it cannot be done like
this)
<CFSET FNCTransfers = temp1 & temp2>
Maby it should be a union and query of query?UNION could be the way to go. the query results will have to
match up
between the 2 queries (field data types need to match for
both queries)
<cfquery name="qryMergedQueries" dbtype="query">
SELECT * FROM query1
UNION
SELECT * FROM query2
</cfquery>

Hi ,
I have a Query that needs to be tuned.
The query joins two views with some filter condition.
While running the individual view query with the filter condition i can able to get the results quickly within a seconds.
But while joining the views conditions of the same criteria which i have used for the individual query takes more than 30 minute.
i am struggling to tuning this query which was written using the views.
Note :
My problem is while checking the explain plan unique sort is taking more cost.
is that i can reduce the time by giving some optimizer hints to reduce the unique sort cost for query using views?
Thanks & regards,

Note :
My problem is while checking the explain plan unique sort is taking more cost.Cost in not necessarily a good comparison to use. The cost is a figure determined on a per-query basis,The problem with cost is that it's a prediction made by the optimizer, rather than the actual measure of query performance. Optimizer often makes mistakes about expected query performance. Ironically, people normally look at query cost when it needs tuning, i.e. when the chance that optimizer made a mistake is especially high.
In many internet forums one can see claims that cost estimates are meaningless across different queries. Such claims are unfounded. When calculated correctly, cost is quite meaningful, and in such cases there is nothing wrong about comparing cost not only for different queries, but also for different databases (if they have same optimizer settings and system stats).
is that i can reduce the time by giving some optimizer hints to reduce the unique sort cost for query using views?Hints are not the way to improve performance. That's an overstatement. The sad truth is that in many cases there is no viable alternative to using hints. Rather than always avoid hints no matter what cost, it's better to understand how hints affect optimizer behavior, and when it's safe to use them.
They are great for identifying where the cause of a performance issue is, but shouldn't be used in production code, as it would be like saying that you know better than Oracle how to retrieve the data, not just now, but in the future as more
data is added and as data is deleted and replaced with new data etc. By adding hints you are effectively forcing the optimizer to execute the query in a particular way, which may be fast now, but in the future may be worse than what the optimizer can determine itself.Hints that force the optimizer to use a specific access path or a specific join method are dangerous -- because the only lock-in one part of the plan, but not the entire plan (e.g. INDEX hint only ensures that an index is used if possible, but it cannot ensure INDEX UNIQUE/RANGE SCAN, so you may end up in a situation when the optimizer is doing an expensive and meaningless INDEX FULL SCAN because of the hint that was indended to force a different, more selective, access method).
Hints that don't do that, but rather prevent the optimizer from trying to be smart when it's better to keep things simple, are relatively safe.
So, use the hints to identify where there are issues in the SQL or in the database design, and fix those issues, rather than leave hints in production code.As a general rule, sure. Here, however, the problem seems to be obvious -- if views are fast separately, and slow when joined, that suggests that the optimizer doesn't merge them correctly.

How get cfspreadsheet to return the query dump in Excel?
I read my data as shown in examples, but my data just displays the query dump. If I add cfheader and cfcontent, the query dump just displays in an Excel.
I'm using CF 9.01 and Excel 2007
shell. Here is my code:
<cfscript>
//Use an absolute path for the files. --->
theDir=GetDirectoryFromPath(GetCurrentTemplatePath());
theFile=theDir & "TrackEverythingXLS.xls";
//Create two empty ColdFusion spreadsheet objects. --->
theSheet = SpreadsheetNew("TBI_2009");
theSheet2 = SpreadsheetNew("TBI_2008");
//Populate each object with a query. --->
SpreadsheetAddRows(theSheet,QO_getAllData);
SpreadsheetAddRows(theSheet2,QO_getAllData_TBI_2008);
</cfscript>
<!--- Write the sheet --->
<cfspreadsheet action="write" filename="#theFile#" overwrite="true" name="theSheet"
sheetname="QO_getAllData">
<cfspreadsheet action="update" filename="#theFile#" name="theSheet2"
sheetname="QO_getAllData_TBI_2008">
<cfheader name="Content-Disposition" value="inline; filename=TrackEverythingXLS.xls">
<cfcontent type="application/vnd.msexcel">
<cfspreadsheet action="read" src="#theFile#" sheetname="QO_getAllData"
query="spreadsheetData">
<cfspreadsheet action="read" src="#theFile#" sheetname="QO_getAllData_TBI_2008"
query="spreadsheetData2">
<cfdump var="#spreadsheetData#" />
<cfdump var="#spreadsheetData2#" />
As you can see, I'm trying to write 2 tabs. That doesn't work either. All the data is dumped into one tab.My initial problem may start with "Simply create your spreadsheet as usual." How do I do that?
With the code I just tried below, I did get a spreadsheet. So using cfheader and cfcontent is correct?
I did not get 2 sheets though.
<cfscript>
//Use an absolute path for the files. --->
theDir=GetDirectoryFromPath(GetCurrentTemplatePath());
theFile=theDir & "TrackEverythingXLS.xls";
//Create two empty ColdFusion spreadsheet objects. --->
theSheet = SpreadsheetNew("TBI_2009");
SpreadsheetAddRows(theSheet,QO_getAllData);
//Create a new sheet.
SpreadsheetCreateSheet (theSheet, "QO_getAllData_TBI_2008"); // 2nd query
//Set the sheet as active.
SpreadsheetSetActiveSheet (theSheet, "QO_getAllData_TBI_2008");
//Populate each object with a query. --->
SpreadsheetAddRows(theSheet,QO_getAllData_TBI_2008);
</cfscript>
<!--- Write the sheet --->
<cfspreadsheet action="write" filename="#theFile#" overwrite="true" name="theSheet"
sheetname="QO_getAllData">
<!--- (no formatting) Works best. 8/10/11 2:54 pm --->
<cfheader name="Content-Disposition" value="inline; filename=TrackEverythingXLS.xls">
<cfcontent type="application/vnd.msexcel">
<cfspreadsheet action="read" src="#theFile#" sheetname="QO_getAllData"
query="spreadsheetData">
<cfdump var="#spreadsheetData#" />
Also, will I be able to code to Sort? Right now, I get an error message saying: "This operation requires the merged cells to be identically sized. (I had selected a Custom Sort on the entire sheet.) Is this a formatting issue?
Thanks for helping me out.
