Multiple Expressions.

Apr 16, 2007

Good Morning all.

Is it possible to put multiple expressions in one cell.



Here is an example of the expressions I'm using. I'm currently having to put them horizontally in a seperate cell.



=Count(IIf (Trim(Fields!NOB_Pickup_L_D_T.Value) = "Y", 1, Nothing))

=Count(IIf (Trim(Fields!NOB_Pickup_L_D_T.Value) = "N", 1, Nothing))

=Count(IIf (Trim(Fields!NOB_Pickup_L_D_T.Value) = "NA", 1, Nothing))



Desired output will look sim to this in one cell







Y = 5

N = 3

NA = 0



Thanks,

Rick

Dataset Filtering With Multiple Expressions

Sep 1, 2007

I would like to know how to dynamically change the And/Or value on the Filter tab within a dataset.

Here are my two expressions within the filter:




Code Snippet
=Switch(Parameters!TotalCostFilterOp.Value = "=",Fields!tcost.Value = Parameters!TotalCost.Value,Parameters!TotalCostFilterOp.Value = ">",Fields!tcost.Value > Parameters!TotalCost.Value,Parameters!TotalCostFilterOp.Value = ">=",Fields!tcost.Value >= Parameters!TotalCost.Value,Parameters!TotalCostFilterOp.Value = "between",Fields!tcost.Value >= Parameters!TotalCost.Value AND Fields!tcost.Value <= Parameters!TotalCost2.Value,Parameters!TotalCostFilterOp.Value = "ie", ISNothing(Fields!tcost.Value), Parameters!TotalCostFilterOp.Value= "<",Fields!tcost.Value < Parameters!TotalCost.Value,Parameters!TotalCostFilterOp.Value = "<=",Fields!tcost.Value <= Parameters!TotalCost.Value,Parameters!TotalCostFilterOp.Value = "<>",Fields!tcost.Value <> Parameters!TotalCost.Value)









Code Snippet
=Switch(Parameters!CompanyFilterOp.Value = "%",LCASE(Fields!company.Value) like "*" & LCASE(Parameters!Company.Value) & "*", Parameters!CompanyFilterOp.Value = "=",Fields!company.Value = Parameters!Company.Value, Parameters!CompanyFilterOp.Value = "ie", ISNothing(Fields!company.Value), Parameters!CompanyFilterOp.Value = "?", LCASE(Fields!company.Value) LIKE LCASE(Parameters!Company.Value), Parameters!CompanyFilterOp.Value = "<>", Fields!company.Value <> Parameters!Company.Value, Parameters!CompanyFilterOp.Value = "?%", LCASE(Fields!company.Value) LIKE LCASE(Parameters!Company.Value) & "*")






The operator for both these is set to "=", and the value is set to "=true".

Based on user selection in a report wizard, the 4th column (And/Or) may need to be changed from 'and' to 'or', or vice-versa.
Is there anyway to accomplish this programatically?

Thanks in advance for you help!

Multiple Select And Sum Expressions On The Same Table SQL…??

Oct 25, 2005

Little complex but I'll try to explain the best I canI have the following table…
 
UserID___Year___Month_____A1____A2____B1____B2
__1_______4______5______45_____5____43____0
__1_______4______6______10_____12___1_____3
__1_______5______5______12_____22___8_____7
__1_______5______6______11_____10___5_____0
 
__2_______4______5______9______65___33____66
__2_______4______6______3______3____10____11
__2_______5______5______44_____2___77_____1
 
 
I want to pull out the data to show the sum of the totals for each year the user is in. The idea is to then be able to see a comparison for year on year on a month by month basis
Eg.
 
UserID____TotalAYear4____TotalBYear4___TotalAYear5____TotalBYear5___Month
__1___________50_____________43___________34____________15__________5
__1___________22_____________4____________21____________5___________6
__2___________74_____________99___________21____________5___________5
 
 
There would be no data returned for UserID2 for month 6 as there is no data for them for year 5 month 6 therefore no comparison can be made.
 
I’ve having real difficulty getting the correct SQL syntax to do this. Any ideas or pointers would be great thanks

Expressions

Jun 7, 2006



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:

(DT_STR, 4, 1252) YEAR( GETDATE() ) + RIGHT("0" + (DT_STR, 2, 1252) MONTH( GETDATE() ), 2) + RIGHT("0" + (DT_STR, 2, 1252) DAY( GETDATE() ), 2) + "_" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("hour", GetDate()), 2) + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("minute", GetDate()), 2) + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("second", GetDate()), 2)

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.)

Any thoughts?

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?

Subquery Expressions Help

Oct 31, 2007

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!

MS SQL:- Regular Expressions

Jun 24, 2008

Hi, the Microsoft SQL Server version is 2000


Basically I want use a basic regular expression but can't seem to get the syntax right.

i want to compare ID_short = ID_Long

ID_short is a truncated version of ID_Long, and I want to search on the beginning only (hence I can't use the 'LIKE' comparative on it's own).

What is the syntax to use Reg Expressions (or if anyone knows a non RegExp way of searching the beginning please let me know).

Can I Set Expressions Programmatically?

Apr 16, 2007

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] + "')"



What would the code look like?

Color Expressions

Jun 5, 2007

Hey everyone,



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.

Greetings!

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 :

Boolean Expressions

Nov 12, 2007

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

=iif((Fields!RevenueGbp.Value = 0.00), "Zero", (Fields!Commission.ValueGbp/Fields!RevenueGbp.Value))

However this does not work. However if i tried the following Boolean query

=iif((Fields!RevenueGbp.Value = 0.00), "Zero", Fields!CommissionGbp.Value)

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!

Anyone help?

As you can see I´m trying to create a folder but it keeps the double slash, how can I fix it?

thanks.

well the real expression is:

@[User::varLogFolder] +"\"+ @[System:ackageName] +"\"+replace(replace(@[User::varFilesCollect],"\","" ),".","")+"\"+"CollectTrnsRxaFecPagLog.txt"

and the error is because:

Using Expressions In FOR LOOP

Apr 11, 2007

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.



Any help appreciated.



Thanks

Date Conversion And Expressions

Aug 31, 2006

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.

Numeric Expressions And Aliases

Mar 8, 2006

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?

Thank you,

Derrick

Regular Expressions In SQL 2005 Using C#

Sep 24, 2006

Hi all,

i wrote a little function that is basically supposed to give me a match of a regular expression in C#. i tested it out in VS05 and it seems to work fine. It hits the fan when i try it on SQL Query analyzer once deployed. Anyone have any idea why?

here is the C# class that I deploy to a db using VS05.

using System;

using System.Data;

using System.Data.SqlClient;

using System.Data.SqlTypes;

using Microsoft.SqlServer.Server;

using System.Text.RegularExpressions;



public partial class RegExTest

{

[Microsoft.SqlServer.Server.SqlFunction(IsDeterministic = true, IsPrecise = true)]

public static string RegExMatch(string pattern, string matchString)

{

Regex r1 = new Regex(pattern);

if (r1.Match(matchString.TrimEnd(null)).Success)

{

Regex testReg = new Regex(pattern);

Match regMatch = testReg.Match(matchString);



string runnumber = regMatch.ToString().TrimEnd('_');

runnumber = runnumber.TrimStart('_');

return runnumber;

}

else

{

return null;

}



}

};

Basically i have a teststring that looks like abc_xxx_nnndef. xxx and nn are both numbers, and im using the pattern _\d{3}_ to test it out in SQL (i need the numbers between '_' and '_'). But it never even proceeds past the if statement in SQL i think. here is the basic SQL that i use to test the above function:

use northwind

go

declare @teststring varchar(50),

@pattern varchar(10),

@out varchar(50)

set @teststring = 'dw_012_34.ext'

set @pattern = '_\d{3}_'

set @out = dbo.RegExMatch(@pattern, @teststring )

select @teststring

select @pattern

select @out



Anyone have any suggestions as to why it works in VS 05 when I use it in a C# program, but fails on the SQL version?

Expressions And Datareader Source

Mar 12, 2007

Greetings my SSIS friends,

Apologies for asking a similar question again but I am still non the wiser with this problem!

Let me explain to you my situation and the method I've adopted to try and solve it.

I have some source data residing in a SQL Server 6.5 database. The source data consists of a single table. For this example I will assume that my table contains only 2 columns, an ID column called result_ID and a Result_Name.

The idea is to retrieve new data each time the package is run. We will know this because the result_IDs in the source table will be greater than the maximum result_ID in my destination table . The way the package should work is like this :

1) Retrieve maximum result_ID from destination table

2) retrieve data from source table where result_ID > maximum result_ID from destination table.



My package consists of a

1) SQL Query Task which retrieves the maximum result_ID and places it in a user variable (type Int32).

2) A Data flow task with a Datareader source adapter which uses an expression to retrieve the data. My expression looks like this : "select * from result where result_id > " + (dt_str, 10, 1252) @[User::max_result_id]

When I run my package the first time all the rows are retrieved (as my destination table is empty to begin with). BUT when I run it the second time the same thing happens again!! All rows are retrieved.

I placed a breakpoint at the point where the variable gets populated with the maximum result_ID and true enough, the variable gets populated with the correct result_ID BUT then that variable gets reset to 0 in my expression!



This problem is driving me crazy! Has anybody out there experienced this kind of problem before?! What are the ways to solve it?!

Thanks for your help in advance.
