How Can I Use A For Loop In A Query ?

Nov 15, 2007

hi all i have the following stored procedure.


declare @AreaID int

select @AreaID = 1

 

select DATEPART(hh, dbo.JobEvent.JobEventDateTime) AS hourbracket, count(ID) as NUMCOUNT

from
 table1 INNER JOIN
                      table2 ON table1.JobId = table2.JobEvent_JobId
where

 (table1.Job_AreaId = @AREAID)


the there are about 300 AREAID's  so my question is do i do a "LOOP"  or is that no efficient and chews up resources on the server ?
what would be a nice clean way to do this ?

thanks

SQL Server 2014 :: Loop And Query CSV Files In Folder Using Union All Query To Form Resultant Table On Server?

Jun 27, 2014

I am trying to run a UNION ALL query in SQL SERVER 2014 on multiple large CSV files - the result of which i want to get into a table in SQL Server. below is the query which works in MSAccess but not on SQL Server 2014:

SELECT * INTO tbl_ALLCOMBINED FROM OPENROWSET
(
'Microsoft.JET.OLEDB.4.0' , 'Text;Database=D:DownloadsCSV;HDR=YES',
'SELECT t.*, (substring(t.[week],3,4))*1 as iYEAR,
''SPAIN'' as [sCOUNTRY], ''EURO'' as [sCHAR],

[Code] ....

What i need is:

1] to create the resultant tbl_ALLCOMBINED table

2] transform this table using PIVOT command with following transformation as shown below:

PAGEFIELD: set on Level = 'Item'
COLUMNFIELD: Sale_Week (showing 1 to 52 numbers for columns)
ROWFIELD: sCOUNTRY, sCHAR, CATEGORY, MANUFACTURER, BRAND, DESCRIPTION, EAN (in this order)
DATAFIELD: 'Sale Value with Innovation'

3] Can the transformed form show columnfields >255 columns i.e. if i want to show all KPI values in datafield?

P.S: the CSV's contain the same number of columns and datatype but the columns are >100, so i dont think it will be feasible to use a stored proc to create a table specifying that number of columns.

HI

I am quite new in query building so I would like to know where can I find some useful information about if, for,.. clauses to use in query analizer.
I would like to set a variable for date(datetime) and use it in if, for,...

SQL Loop Query Problem.

Jul 25, 2007

I'm a relative novice at using sql and I'm struggling with a particular problem. I'm not sure if this is the appropriate place to post this sort of thing but after much fruitless research I need to try and enlist someone's help.

I have a table of pay dates with a paid amount. I want to write a statement that creates a table that breaks those out into the daily amount paid. So it would create a table with a row for each date in the pay period and the amount paid each day.

For example: My existing table has an employee Bob who was paid $1000.00 on January 14. I want then create a table that has records for January 1 - 14 and $71.43 for each date. I think it I need some kind of loop for the whole thing to run through but I can't get the syntax right. I've thought about creating a temp table with all of the dates in that pay period but again, in order to create that temp table I feel like I need some sort of while loop that creates the rows for each date.

Any help or suggestions would be greatly appreciated. I'm at wits end .

Dynamic Query In While Loop

Nov 18, 2011

@strSql is a dynamic query in while loop which can return single record, single row of records, multiple rows of records.

So only if it returns single record then I have to store it otherwise convert to xml before storing.

1) If it returns 1 record(1row and 1 column) then save as it is.
2) if it returns a row with more than 1 columns then convert to xml before saving.
2) if it returns data rows then convert to xml before saving.

Loop Through Result Set Using Value In Query

Mar 27, 2012

I have to pull values from a mysql table, then loop through the result set using the value in an mssql query as shown below. I also have an array ($all_lobs[]) of about 100 values that must be looped through for each value pulled from the mysql table:

$tod=date("n/j/Y",time());

//this is pulling the data from the mysql table
$query2="select CustId from prospect_CustId ";
$result2=mysql_query($query2,$link_id_mysql);
while($custs=mysql_fetch_row($result2))

[Code] .....

If I pull only 100 records from the mysql table, this takes about 1 second to run. However, if I pull 200 records, it takes about 60 secs to run. And, if I pull 300 records, it takes about 200 secs to run. After about 500 records, it takes almost a second per record to run!

Since I have 20,000+ records to pull, this takes hours...

Unfortunately, we are not allowed to modify the mssql tables at all, only query them.

Avoiding Query In Loop

Jun 9, 2008

Hello all,

I currently have an asp script that is generating a 12 month rolling report. From asp I'm running a for loop with 12 iterations, each one sending the following query:

select count(a.aReportDate) as ttl from findings f left outer join audits a on a.aID = f.auditID
where f.findingInvalid <> 1 and month(aReportDate) = " & Mo & " and year(aReportDate) = " & Yr

where the Mo and Yr variables are incremented accordingly.

I actually have 4 sets of data being pulled back to populate a graph, so this results in 48 queries with each page load! Obviously not ideal. So I'm hoping to reduce this to 4 queries. I was playing with the following in enterprise manager:

DECLARE @DT DATETIME
DECLARE @CNT INT
SET @DT = '10/31/07'
SET @CNT = 1
WHILE(@CNT < 12)
BEGIN
select count(a.aReportDate) as ttl from findings f left outer join audits a on a.aID = f.auditID
where f.findingInvalid <> 1 and month(aReportDate) = month(@DT) and year(aReportDate) = year(@DT)

SET @CNT = @CNT + 1
END

I haven't yet added any logic to increment the date, but my concern is that it looks like it is returning 12 separate results. Is there any way to combine this all into one resultset that will be passed back to my asp script? Hopefully this makes sense?

Suggestions on a completely different approach would also be welcome.

Thanks!

Imitating Nested For Each Loop In SQL Query

May 25, 2007

Dear All,

I need to create a query to list all the subfolders within a folder.

I have a database table that lists the usual properties of each of the folder.

I have another database table that has two columns

1. Parent folder
2. Child folder

But this table maintains the parent child relationship only to one level.

For example if i have a folder X that has a subfolder Y and Z.
And Y has subfolders A and B.
and B has subfolder C and D
and C has subfolder E and F

The database table will look like

parentfolder child folder
X Y
X Z
Y A
Y B
B C
B D
C E
C F

I want to write a query which will take a folder name as the input and will provide me a list of all the folders and subfolders under it. The query should be based on the table (parent - child) and there should not be any restriction on the subfolder levels to search and report for.

I have been banging my head to do this but i have failed so far. Any help on this will be highly appreciated.

Loop By Passing Variable Into Query

Nov 2, 2007



Hi all,

I'm have created a data flow that uses an OLEDB source with a SQL Query. In the WHERE statement of this query is a condition for the storecode. I want to figure out how to create a loop that will cycle through a list of storecodes using a variable which is passed to the dataflow in turn to the OLEDB source's query and runs through the process for each store.

The reason i'm using a loop is because there are about 15 million records that are merge joined with 15 million others which is causing a huge performance problem. I'm hoping that by looping the process with one store at a time it should be faster. Any ideas would be greatly appreciated.

Is There A Way To Loop Over Report Parameters, And Format Them Before Passing Them Onto The Query

Nov 13, 2007

Good morning all,


I have a report which is getting its parameters from an ASP.net page. My ASP developer wants to send in simple values, such as the list 1,2,3,4 for a parameter. However my report needs that list to look like [CD RSRC].[RSRC].&[1], [CD RSRC].[RSRC].&[2], [CD RSRC].[RSRC].&[3], [CD RSRC].[RSRC].&[4].


Is there any way, on the report services side, to capture an incoming report parameter, parse it, loop over the parsed values and format them?


I don't think there is, but I wanted to check before I go back to the developer and tell him he has to send in tuple lists.


Thanks,
Kathryn

Newbie Question: Table Polling And Select Query In A Loop

May 2, 2007

Hi,



I am a newbie in SSIS.

Can anybody please help me in the following.



Here is the task that I want to achieve:



1. continously poll a db table every 1 minute,

if the value of a paticular cell in the table has changed since last poll,

then initiate the second task



2. do a select query that picks about 10,000 new rows off another db table,

the 10,000 rows should then be stored in a in-memory dataset.

Every time the poll initiates a new select query, it should insert the new rows to the existing in-memory dataset.

thus if the select runs for 2 times in 2 minutes, the the in-memory dataset would contain a maximum of 20,000 rows.



3. Then I want to apply a set of transformations on the dataset and then finally update some db tables, push some records to the ssas database. (push mode incremental processing)



which sub tasks can be achieved and which cannot.

if not, Is there a workaround?



Please do provide some specific links that accomplish some of these similar tasks.



I have tested some functionality, like

doing a full processing of a ssas database.

reading from a database table and inserting into a flat file.

I tired to use the ExecuteSQLTask, and i also assigned the resultant to an user:variable. the execution completed succesfully but I am not able to see the value of the variable change. also I am not able to use the variable to figure out a change in previous value and thus initiate a sql select. or use the variable to do anything.





Regards

Vijay R

empnum, empname, Tin, Tout, Thrs

what I would like to do is populate a grid view the a select statement that does the following.

display each empname and empnum in a gridview returning only unique values. this part is easy enough. in addition to these values i would also like to count up all the Thrs for each empname and display that sum in the gridview as well. Below is a little better picture of what I€™m trying to accomplish.

Tbltimes

|empnum | empname | Tin | Tout | Thrs |

| 1 | john | 2:00PM | 3:00PM |1hr |

| 1 | john | 2:00PM | 3:00PM | 1hr |

| 2 | joe | 1:00PM | 6:00PM | 5hr |

GridView1

| 1 | John | 2hrs |

| 2 | Joe | 5hrs |

im using VWD 2005 for this project and im at a loss as to how to accomplish these results. if someone could just point me in the right direction i could find some material and do the reading.

While Loop

Mar 3, 2008

Hello everyone,I've got this While loop here which is giving me a problem:WHILE (SELECT ProductId FROM _ShoppingCart WHERE CartId = @CartId) IS NOT NULLBEGIN            DECLARE @ProdId int, @ProdSize varchar, @ProdQuan int            SELECT @ProdId = ProductId, @ProdSize = ProductSize, @ProdQuan = Quantity FROM _ShoppingCart WHERE CartId = @CartId                                   If @ProdSize = 'XL'            BEGIN                UPDATE                    _ProductBatches                SET                    XL = '0'                WHERE                    ProductId = @ProdId            END            DELETE FROM _ShoppingCart WHERE ProductId = @ProdId AND CartId = @CartIdEND The problem is that the IF statement isn't being executed. And I know for a fact that 'XL' is ProductSize in my _ShoppingCart database. Whats even stranger is that my delete statement is being executed. So @ProdId is Being set correctly, but when it gets to the IF @ProdSize = 'XL' it doesn't get executed for some reason. If @ProdId is being recognized correctly in my DELETE statement, why is my @ProdSize not being reconized correctly in my IF statement. I checked my _ShoppingCart database, and my ProductSize is definitely 'XL'. Can any one see what could be going on here.  Thank you, Alec

For Loop

Jan 26, 2004

HeaderLoop: for forHeader as curHeader dynamic scroll cursor for
select lngALSHeadrID from "DBA".ALSHEADR where lngFedTaxID>0 do
set AcctNum=lngALSHeadrID;
exec "DBA".sp_ALSHeadr2Policy(AcctNum);
set Cntr=Cntr+1
end for;


The above is the sybase version of a 'for loop' . The query
select lngALSHeadrID from "DBA".ALSHEADR where lngFedTaxID>0 results in 1000 results.
How do I change that in SQL?? Do we have a for loop ??
I checked in BOL but it is confusing with "browse" etc n some other options.

can I write like this?


for { Browse { declare curHeader dynamic cursor for
select lngALSHeadrID from "DBA".ALSHEADR where lngFedTaxID>0 }
set @AcctNum=lngALSHeadrID;
exec "DBA".sp_ALSHeadr2Policy(@AcctNum);
set @Cntr=@Cntr+1
}


I duno its just my guess, can any one help me out. @Cntr and @Acctnum are declared
in the beginnning.
