I have a table in a RDLC report which is utilized as a subreport, and the first column of this table is a static string. Does anyone know how I can determine if a row is the first in the table. I tried using "=First("My String")" but it didn't work.
Looking at the link supplied by ThatBloke in his answer, I found the RowNumber command.
Which means that this worked:
=IIf(RowNumber(Nothing)=1,"myString", "")
Aggregate functions work with "Scope', referring to the paragraph scope in this MSDN article, might help...
http://msdn.microsoft.com/fr-fr/library/ms252112(VS.80).aspx"
From what I understand you may have to define a scope or try =First("MyString", Nothing).
=IIF((RowNumber(Nothing) Mod <>)=0)
<> Indicate No of Rows Which you want To Display

I have the following XML structure. I am trying to extract the attributes StartDate and EndDate of the relationship period, that is only if rr:PeriodType is RELATIONSHIP_PERIOD.
However, the nodes for "relationship" and "accounting" have exactly the same name and am not sure how to proceed.
<rr:RelationshipPeriods>
<rr:RelationshipPeriod>
<rr:StartDate>2018-01-01T00:00:00.000Z</rr:StartDate>
<rr:EndDate>2018-12-31T00:00:00.000Z</rr:EndDate>
<rr:PeriodType>ACCOUNTING_PERIOD</rr:PeriodType>
</rr:RelationshipPeriod>
<rr:RelationshipPeriod>
<rr:StartDate>2019-01-02T00:00:00.000Z</rr:StartDate>
<rr:PeriodType>RELATIONSHIP_PERIOD</rr:PeriodType>
</rr:RelationshipPeriod>
</rr:RelationshipPeriods>
I tried using this code
ldply(xpathApply(xmlData, '//rr:RelationshipPeriod/rr:StartDate', getChildrenStrings), rbind)
But doesn't work well as it's hard to understand if it is extracting accounting or relationship period.
Any help would be greatly appreciated!
For rr:StartDate use XPath:
//rr:RelationshipPeriod[rr:PeriodType='RELATIONSHIP_PERIOD']/rr:StartDate
But probably better to first find the correct rr:RelationshipPeriod using XPath:
//rr:RelationshipPeriod[rr:PeriodType='RELATIONSHIP_PERIOD']
See this answer on how to reuse the result of a XPath.
But don't use // in front of rr:StartDate and rr:EndDate
I have read the docs for MariaDB's REGEX_REPLACE but cannot get my query to work. I am storing links in a column, link and want to change the end of the link:
From www.example.com/<code> to www.example.com/#/results/<code> where <code> is some hexidecimal hash, e.g. 55770abb384c06ee00e0c579. What I am trying is:
SELECT REGEX_REPLACE("link", "www\\.example\\.com\\/(.*)", "www\\.example\\.com\\/#\\/results\\/\\1");
The result is:
Showing rows 0 - 0.
I wasn't able to figure out what the first argument was--the documentation says "subject". Turns out it's just the column name. So this works:
UPDATE my_table
SET my_link = REGEXP_REPLACE(
my_link,
"http:\\/\\/www\\.example\\.com\\/(.*)",
"http:\\/\\/www\\.example\\.com\\/#\\/results\\/\\1")
WHERE my_link IS NOT NULL
I am trying to set a label in a gridview not to show a particular date if it is returned (it is because it is a default date and is not needed).
The code I have used is
<%# 'Convert.ToString(Eval("DateTaken")).Equals("01/01/1899") ? "" : Eval("DateTaken")'%>
Unfortunately, when I try and compile it the code won't run. I have tried to find an answer by research, but have not been able to do so.
It uses part of Chris's answer, but Equals does not work. Changing this to Contains does when parsing the value as year
<%# 'Convert.ToString(Eval("DateTaken")).Equals("01/01/1899") ? "" : Eval("DateTaken")'%>
This is not valid syntax as far as I am aware. You have single quotes ' wrapping your statement which is likely confusing the parser a lot. I'm not sure what you intend them to be doing but I'd suggest trying without:
<%# Convert.ToString(Eval("DateTaken")).Equals("01/01/1899") ? "" : Eval("DateTaken")%>
I can't test this but it looks like it should work.
Also for the comparison (I assumed you'd tested that elsewhere first) I suspect you may have problems with the fact that Convert.ToString likely includes a time element. Instead I would suggest specifying what string format you want to be outputted. Or even better assuming that it is a DateTime you are getting back compare it as a DateTime. Either of the following should work as a reliable comparison
(((DateTime)Eval("DateTaken")).ToString("yyyy-MM-dd")=="2014-03-05")
(((DateTime)Eval("DateTaken")).Date==new DateTime(2014,03,05))
I'm importing an .xls file using the following connection string:
If _
SetDBConnect( _
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & filepath & _
";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1""", True) Then
This has been working well for parsing through several Excel files that I've come across. However, with this particular file, when I SELECT * into a DataTable, there is a whole column of data, Item Description, missing from the DataTable. Why?
Here are some things that may set this particular workbook apart from the others that I've been working with:
The workbook has a freeze pane consisting of the first 24 rows (however, all of these rows appear in the DataTable)
There is some weird cell highlighting going on throughout the workbook
That's pretty much it. I can't see anything that would make the Item Description column not import correctly. Its data is comprised of all Strings that really have no special characters apart from &. Additionally, each data entry in this column is a maximum of 20 characters. What is happening? Is there any other way I can get all of the data? Keep in mind I have to use the original file and I cannot alter it, as I want this to ultimately be an automated process.
Thanks!
Some initial thoughts/questions: Is the missing column the very first column? What happens if you remove the space within "Item Description"? Stupid question, but does that column have a column header?
-- EDIT 1 --
If you delete that column, does the problem move to another column (the new index 4), or is the file complete. My reason for asking this -- is the problem specific to data in that column/header, or is the problem more general, on index 4.
-- EDIT 2 --
Ok, so since we know it's that column, we know it's either the header, or the rows. Let's concentrate on rows for now. Start with that ampersand; dump it, and see what happens. Next, work with the first 50% of rows. Does deleting that subset affect anything? What about the latter 50% of rows? If one of those subsets changes the result, you ought to be able to narrow it down to an individual row (hopefully not plural) by halfing your selection each time.
My guess is that you're going to find a unicode character or something else funky is one of the cells. Maybe there's a formula or, as you mentioned, some of that "weird cell highlighting."
It's been years since I worked with excel access, but I recall some problems with excel grouping content into some areas that would act as table inside each sheet. Try copy/paste the content from the problematic sheet to a new workbook and connect to that workbook. If this works you may be able to investigate a bit further about areas.
I am trying to use regex generators to create an expression, but I can't seem to get it right.
What I need to do is find the following type of string in a string:
community_n
For example, within the string which may be
community community_1 community_new_1 community_1_new
from that, I just want to extract community_1
I have tried /(community_\\d+)/, but that is clearly not right.
Try adding word boundries, so
/(\\bcommunity_\\d+\\b)/
Try using the regex (community_\d+).
Though I could be incorrect since I don't know which language you are using.
(For some reason I cannot add comments, I can only answer questions).
