I'm dealing with queries that manages a lot of data consolidation and I'm having to repeat large blocks of code to get the desired result.
I'm wondering if that is any way to make it simple.
My queries looks like this:
Code BlockSELECT
(A + B) AS C,
(D + E) AS F,
(G + H) AS I,
(A + B) * (D + E) AS total1,
(D + E) * (G + H) AS total2,
(A + B) * (G + H) AS total3,
(A + B) * (D + E) * (G + H) AS total
FROM table
Can I somehow declare each part of the expression and make it something like this?
Code Block
SELECT
(A + B) AS C,
(D + E) AS F,
(G + H) AS I,
C * F AS total1,
F * I AS total2,
C * I AS total3,
C * F * I AS total
FROM table
Maybe it seems silly, but each sub-expression, on the real life, includes a lot of CASEs and aggragate functions and my codes are getting complex and confuse.
Since I have lots of code pieces that I repeat more than once, I would like to make it simpler.
I am new to SSIS, so I am hoping there is an easier way to do this...
I need to evaluate a date in a field and determine if it is between the beginning and end of whatever the current month is... In Access, this was written as something like:
IIF(datevalue >= CDate(Format(Now(),"mm/01/yy")) AND datevalue < CDate(Format(DateAdd("m",1,Now()), "mm/01/yy)), value1, value2)
Trying to recreate this in SSIS using expressions during a derived transformation has been extremely difficult. Here is what I came up with:
Dear All, I want to practise writing complex T sql queries in SQl Server 2005 which involve several joins, sub-queries in a single query. This kind of queries are commonly required in Reporting scenarios where a single report may have to be prepared from 2,3 or more tables. Presently I am able to write queries of moderate complexity. Therefore I am looking for web tutorials, books which contains some solved examples as well as some Unsolved ones. The Unsolved ones should have the answers given so that one comes to know if he makes a mistake. The web tutorials can be from paid sites as well. If any of you have a good collection of such queries then pls be kind enough to send it to me.I will give my email id for the purpose. If anybody can help in some other way pls let me know. Your help will be highly appreciated. Thanks .
i am getting to trip with SQL Server and i find it is quite interesting. please send me complex TSQL queries which would help me to test my SQL server expertise. do let me know what are the URLs where i can find complex TSQL Queries i appreciate pointers in right direction

Alright just starting out in ASP.NET and it's making my head spin, but I think I'm getting it.My schema in brief : Images, Categories, and a table in the middle so we can have a many-to-many relationship between images and categories. My issue is searching. I can search by keyword, and limit it to categories. So, in pseudo sql.. SELECT ... WHERE keyword LIKE '%test%' and category_id in (1,5,20,66); I made a variable for the keyword no problem. But how can I get this dynamic list? Or, is there another way about going this problem?
Hello Friends. I have few doubts regarding the use of Sqldatasource server control. Is the control flexible enough to achieve these things:- 1.To perform complex queries using Sqldatasource. For eg:- using JOIN to retrieve/insert data from/into multiple tables.2.Performing cascading dropdownlist using sql database as datasource.3.Performing For loops eg:-populating the multiple items into the listbox from sqldatasource. and retrieving them at once.4.use ajax update panel.etc.any example/sample on how to achieve these task?thanks.jack.
Any recommendations for good advanced t-sql books/articles? I find myself involved with writing increasingly more complex queries and after spending a few hours on some, and then searching on this site for potential answers/help, I am wondering if there might be some good books on creating more advanced/complex t-sql for real world scenarios.
I am not very good in queries. Could you please suggest me some web site/Tutorial/Artical where i can get Study Material for complex and real life queries. I know the syntexes, I just need to practice queries to enhance my skills
Any suggestions on how to simplify this piece of code:
'locationCount'= CASE dbo.#requestsbyyeartemp.themonth when '1' then (select count(distinct location) from #requestsbyyeartemp where themonth=1) when '2' then (select count(distinct location) from #requestsbyyeartemp where themonth=2) when '3' then (select count(distinct location) from #requestsbyyeartemp where themonth=3) when '4' then (select count(distinct location) from #requestsbyyeartemp where themonth=4) when '5' then (select count(distinct location) from #requestsbyyeartemp where themonth=5) when '6' then (select count(distinct location) from #requestsbyyeartemp where themonth=6) when '7' then (select count(distinct location) from #requestsbyyeartemp where themonth=7) when '8' then (select count(distinct location) from #requestsbyyeartemp where themonth=8) when '9' then (select count(distinct location) from #requestsbyyeartemp where themonth=9) when '10' then (select count(distinct location) from #requestsbyyeartemp where themonth=10) when '11' then (select count(distinct location) from #requestsbyyeartemp where themonth=11) when '12' then (select count(distinct location) from #requestsbyyeartemp where themonth=12) end
locationCount is a variable in a temp table. I am looking for ways to make things less repetitive and more efficient.
I'm currently working on a series of comparison queries, between data from different countries.
The bad thing about this is, that many countries use special symbols such as ^ ~ ¨ ´ ` which basically means I have a tough time making the query effecient.
How would I work about converting Jiņi to Jini, so I can compare properly. Is there any way at all?
I want to have this query insert a bunch of XML but i get this error...

I have web forms with about 10-15 optional search parameters (fields) for a give table. Each item (textbox) in the form is treated as an AND condition.
Right now I build complex WHERE clauses based on wheather data is present in a textbox and AND each one in the clause. Also, if a particular field is "match any word", i get a ANDed set of OR's. As you can imagine, the WHERE clause gets quite large.
I build clauses like this (i.e., 4 fields shown):
SELECT * from tableName WHERE (aaa like '%data') AND (bbb = 'data') AND (ccc like 'data%') AND ( (xxx like '%data') OR (yyy like '%data%') )
My question is, are stored procedures better for building such dynamic SQL clauses? I may have one field or all fifteen. I've written generic code for building the clauses, but I don't know much about stored procedures and am wondering if I'm making this more difficult on myself.
When creating expressions we have access to a list of functions. It is my understanding that while these functions seem to have the same names and parameters as SQL functions, they are not so. They are implemented in the package libraries themselves. It is also my understanding that this function library cannot be extended to add new ones.
Am I correct? If so... why not?
Leaving alone the fact that they follow the same screwy names as SQL (instead of .NET on which SSIS is built on) and what seems to be a limited library (i.e. You have YEAR(), MONTH(), DAY() functions but no HOUR(), MINUTE(), or SEC() functions -- instead you have to use DATEPART())
I mean honestly... a common expression for most people is using date and times for folder and filenames... So instead of a simple .NET type expression of DateTime.ToString("yyyyMMdd") or Format(DateTime.Now, "yyyyMMdd_hhmmss") I end up with the very complex:
Personally I find myself using Script Tasks and Variables to "build" my expressions and just use Expressions to set the property to the variable. (Which I think may defeat the full purpose of expressions.)
I have a table CREATE TABLE [dbo].[CmnLanguage]( [Id] [char](2) NOT NULL CONSTRAINT PkCmnLanguage_Id PRIMARY KEY, [EnglishName] [varchar](26) NOT NULL, [NativeName] [nvarchar](26) NOT NULL, [DirectionType] [smallint] NOT NULL, [IsVisible] [bit] NOT NULL, [CreatedDateTime] [datetime] NOT NULL DEFAULT GETDATE(), [ModifiedDateTime] [datetime] NULL) We will use these 3 queries select * from CmnLanguage where IsVisible = 0select * from CmnLanguage where IsVisible = 1select * from CmnLanguage I want to make a method which handles these queries. But at the back end on Stored Procedures We have to write 3 queries Which I don't want to do. I want to minimize the queries and conditions and want to just write one for these 3 Can any one do it?
Hello all, I have come across a road block once again and it is probably something fairly easy to do. I have 3 queries that give counts with different criteria. They are: SELECT building, COUNT(asmt_number) AS Cnt FROM dbo.mr_gb_asmt WHERE (school_year = 2008) AND (due_date <= CONVERT (DATETIME, '2007-10-26 00:00:00', 102)) AND (publish_scores = 'N') GROUP BY building ORDER BY building SELECT building, COUNT(asmt_number) AS Cnt FROM dbo.mr_gb_asmt WHERE (school_year = 2008) AND (due_date <= CONVERT (DATETIME, '2007-10-26 00:00:00', 102)) GROUP BY building ORDER BY building SELECT building, COUNT(asmt_number) AS Cnt FROM dbo.mr_gb_asmt WHERE (school_year = 2008) AND (due_date <= CONVERT (DATETIME, '2007-10-26 00:00:00', 102)) AND (publish_asmt = 'N') GROUP BY building ORDER BY building My question is how can I combine these three queries into one so that I only get one record set? Thanks for all the help!
I'm building SSIS packages through code and I would like to set the properties of some custom tasks (not data flow tasks) to expressions. I've done some searches but turned up nothing. This is the only thing I'm hitting a brick wall on at the moment; Books Online has been excellent in detailing how to create packages via code up to this point.
For the sake of argument, let's say I want to set the SqlStatementSource property of an Execute SQL task to this value:
"INSERT INTO [SomeTable] VALUES (NEWID(), '" + @[User:omeStringVariable] + "')"
I know that you can make an expression that will make it one color if a certain condition is met and a different one if it is not but is there anyway to make it so that if a number is less than another it's one color, if it's greater it's a different color and if they're equal it's a third color? Thanks for the help.
I am attempting to implement the following case statement BEFORE getting the data in to my destination table but I don't know how to create an expression for it.
In the mapping section of my OLE DB destination component I can only do mapping but I can't actually manipulate the data before it gets to the destination table.
What do I have to do to implement :
case when SOPD.PRICE_TOP_NUMBER is NULL then -8 else SOPD.PRICE_TOP_NUMBER end AS price_top_number,
I have a unusual problem, well it is unusual becaue i cannot understand it.
I am retrieving the following data, Revenue, Sales, Commission, and calculating Commission Rate in the report itself.
I got warnings that a textbox that was attempting to calculate the Commission Rate was trying to divide by zero.
When I analysed the data, I realised that indeed there were instances when Revenue was 0.00 and therefore when calculating the commission rate, commission/revenue it returned an error.
I then thought I'd do the following in the expression field
it does work. In fact if I use any other identifier or use two field thats add, subtract or multiplied with each other it will work. The problem only arises is when I decide to divide two fields together.
Strangely if the condition is satisfied - [Fields!RevenueGbp.Value = 0.00] - it will still try to work out the division even though it should just return Zero!

I need to create a While Loop with the FOR LOOP task.
According to my SSIS book, "to set up a While Loop in the For Loop, simply create an expression that tests a variable that can be modified by some workflow either inside or outside the For Loop"
What I want to do is, put an FTP task (whose job it is to receive a file) inside the For Loop.
I want the control flow to go like:
FOR LOOP --> FTP task --> file received? --> NO --> set variable 0 --> FOR LOOP --> check for variable --> is variable 1? --> NO --> FOR LOOP --> FTP task
and so on, until the variable is set to 1, indicating the successful transfer of the file
According to my book, this can be done simply with the use of expressions.
My question is, how do I write the expressions, both for the FTP task (which will set the variable to 0 or 1), and then the expression for the For Loop, which will evaluate the variable in its expression?
So, seems like I need to write 2 expressions, but not sure how.
I have a table with about 20,000 records that have a date field, stored as a datetime in the database like '8/28/2006 8:42:14 AM'. The dates range from March 2004 to current. What I would like to do is retrieve the dates in that format (month year) and put them in a dropdown. I have this so far:SELECT DISTINCT DATEPART(month, dte_date) AS Expr1, DATEPART(yyyy, dte_date) AS Expr2 FROM myTable ORDER BY DATEPART(yyyy, dte_date), DATEPART(month, dte_date)And the query returns the information that I want, but I can only bind one field to the dropdown. I was thinking that if I return the results a single expression (concantenate?) then I could bind that to the dropdown. I'm not sure as how to go about this. Also, the month returned is numeric and I would rather have the name of the month returned (like "July" instead of "7"). Thanks in advance to anyone who helps me.
I'm in the process of building a site and converting views/tables/queries from an Access database to SQL. I've done this quite a few times, and never had any significant issues I couldn't figure out on my own.
In Enterprise Manager, I've created a view and in the query, I need to create an alias that is similar to below:
SELECT ((monthmult) + ((b2avg*15)-(av2*10)) + (lp1+lp2) + ((b1avg*30)-(av1*20))) as PIndexValue
which is how the formula reads in the Access view.
However, when I got to run the query, SQL strips out all of the parentheses and calculates the value in left to right order:
(monthmult + b2avg*15-av2*10 + lp1+lp2 + b1avg*30-av1*20) as PIndexValue
Which gives me an incorrect value.
Does anyone know why this is happening, or am I just unaware of the right way of doing it?
I am creating a check constraint on a field (GRID_NBR) for values between 1 & 99. I am a little confused on creating the expression for it (Books online is vague).
Can I use the following expression: GRID_NBR BETWEEN 1 AND 99
Or do I have to use: GRID_NBR > 0 AND GRID_NBR < 100
I have a crappy old database that has an email field with a lot of bad data, and I need to use SSIS to extract a list of names & email addresses.
I have an OLE DB Source set up to pull the relevant columns out of the database. Is there a way that I could setup a Regular Expression based filter to disregard any rows where my email Regex does not match the value of the email column?
