Expression Help Needed

Oct 23, 2006

I use the following expression to convert zero length character strings to and int value of 0 :

comno_type == "" ? "0" : comno_type

however, some of the data I'm trying to copy contains 1 character long blank strings or " " to be precise. Can I get the above expression to handle both the zero and 1 char strings at the same time. I've tried things like:

comno_type == "", " " ? "0" : comno_type

but this is a syntax error.

Would I need to do separate expressions to handle each type of string? and if so, how do I get them into the same destination column?

Thanks

SQL Expression Needed

Jan 12, 2006

Hello, I need to create a table where a column's data should have a hypen inserted after the second character. The table will accept a large input of rows, so I think it would be better to use a SQL expression or formula on the column to provide the hyphen on insert rather than doing an update statement later. There is no way of knowing how many characters will follow the hyphen.
So for example... 888888 would become 88-8888
or 5555555555555555 would become 55-55555555555555
Any help would be great!

Help Needed With Expression

Feb 15, 2008

Hi,

I have a For Each Loop container that sniffs for a specific file. I have 2 branching processes that flow out fo the For Each loop and I need either the one or the other to execute based on whether the file was found.

In other words. If I the For Each Loop picks up the file and does a few things with it with components insite the container, then process A must flow out of the FELC. If it doesn't find any files, Process B must flow out of it.

I can't use succes or failure's since it's not a failure when the FELC doesn't pick something up. I guess I have to do this with an expression but I don't know how to do this expression...

Any1 have an idea?

Cheers
Mike

Time Parameter Expression Needed

May 30, 2007

Hello All,

I am trying to set parameter in reporting services that lets the user select "All Hours" or "Cour Hours" of the day in a given date range.

Core hours would filter the transactions (and aggregations) that happened between 6am and 10pm on certain days and another range of hours on some days. The days that the core hours exist will be static. i.e. every day the core hours are 6am to 10pm but on Mondays the core hours are Midnight to 2am and then 6am to 11:59:59.

I am trying to figure out what that code would look like. Any help is appreciated.

URGENT - My Error Or Bug? The Result Of The Expression Cannot Be Written To The Property. The Expression Was Evaluated, But

Directly using C:sql_working_directoryMLSAZPhoenixDocsArmls_Schema Updated 020107.xls
as connectionString works

However - I'm trying to deploy the package - and trying to use expression:
@[User::DIR_WORKING] + "\Docs\Armls_Schema Updated 020107.xls"
which causes the same error to occur

(Same error with other Excel source also:

Reporting Services :: Running Value Expression Within Lookup Expression In SSRS?

Oct 28, 2015

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".

I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.

Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.

This is the lookup expression that I added for the 2nd column.

=Lookup(Fields!salesperson.Value,Fields!sales_person.Value,RunningValue(Fields!sales_amount.Value,
sum, " sales_person"),
"Largeappliances").

I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.

(processing): (SortExpression ++ m_context.ExpressionType)

Expression Help

Feb 20, 2008

Is it possible to nest expressions within a script in a similar fashion to how they're nested within the expression editor?

I have a requirement to strip trailing digits from a string field, so that only two decimal places are left.

e.g.
1.12345 becomes 1.12
12345.6789 becomes 12345.67

I would do this in the expression editor but I need to use Script component because there are a multitude of conditions that need to be evaluated first which I will do inside a Select Case statement.

I'm wrestling with code that looks like

Newratefield = ratefield.Substring(1, Findstring(ratefield, ".", 1) + 2)

but VB doesn't like the 'Findstring(ratefield, ".", 1) + 2)' part.

Any suggestions on what I can do here?

Regular Expression?

Mar 25, 2008

HiI'm looking to return rows from a table where a column is LIKE a keyword. This is my current code:SELECT DISTINCT business_name FROM Table WHERE business_name LIKE @keyword + '%' ORDER BY business_name ASCThe problem with this is that if a business is called "The White Ship Inn", and the keyword to match is "White Ship" it will not match. If i put another wild card in front of @keyword then this finds too many matches - i need it to match against columns which either start with the keyword, or have a whitespace in front of them. Is there some kind of T-Sql i can use or will i have to go down the regex route (using this (http://www.codeproject.com/KB/mcpp/xpregex.aspx)) ?cheers

Is It Possible To Format An Expression?

Sep 12, 2005

I have an expression based upon 2 fields in a view that I want to be able to divide and then multiply by a number. Whenever I do the division portion of the calculation all I get are 0 & 1's. I was hoping to use the percentage in other calculations.
Is there something similar to FORMAT(X/Y,0.00)?

(vwLbrPosSum.PosMin/vwMinByEmp.TotMin) x (a)vwLbrPosSum.PosMin or (b) 2400 or (c)vwMinbyEmp.TotMin - 2400
If the person worked more than 40 hrs I could allocate the OTMins to the different positions in labor reporting.

Expression Question

Mar 11, 2008

Can anyone tell me if I am doing something wrong

I am creating a sql string passing some parameters in the expression field of a string variable(defined at the data flow task level)

I have the following in the expression field

"select * FROM TDATA where CODE ='4' and item ='5' and ddate > (Current_date - " + @[User :: DateOffset] + ")"

DateOffset is a package level variable that is defined as an integer that has a value of 7.

I keep getting a "The expression for variable "SqlStr" failed evaluation. There was an error in the expression."

If I just have the simple query "select * FROM TDATA where CODE ='4' and item ='5' " the expression works fine

Can someone tell what I am doing wrong

Thanks in adv
