I'm trying to learn REGEX and I was wondering its usefulness with dates.

 

I have some hypothetical dates I want to convert to Alteryx's Date format.  Currently I'm using this formula:

 

REGEX_replace([Field1],'(.*?)/(.*?)/(.*)','20$3-$1-$2')

 

I don't know how to pad the left of the day and month portions.  Is there a way?

 

Starting Date	Current Conversion	Desired Conversion
2/3/16	2016-2-3	2016-02-03
2/13/16	2016-2-13	2016-02-13
12/3/16	2016-12-3	2016-12-03
12/13/16	2016-12-13	2016-12-13

 

I'm sure that there are some great macros that convert dates, but i am only doing this to teach myself the how i can better use REGEX.

Hello everyone,

 

I am quite new to Alteryx and am currently working on a workflow that writes several sheets in a single Excel file. Therefore, I made use of the Block Until Done Tool to unparallelize the run-through of workflows. However, after adjusting some things in the model, I now get an 'Internal Error Message': Block Until Done (xx) Internal Error: AddRecord() - MetaInfo must be successfully set before adding records.

 

I've compared it to a previous version where the run worked withough error message but I can't figure out what the problem might be...any ideas on how to solve this issue?

Thank you very much in advance,

Isa

Hi Folks,

 

I have created a workflow and it works fine .I am facing a peculiar issue where in once I close the workflow  and open it and click on any transformation(Filter,select,join) within it , the columns turns yellow showing missing but when I run the workflow,it runs fine and the columns turns normal again .The issue happens with every closure and opening of the workflow.

PFA a screenshot of the issue .Could someone help me understand the issue ?

Hi,

 

I am doing a POC on Json file and Parsing capabilities of Alteryx . I have built a Json file and i parsed it and Crosstab it immeditely. When i cross checked the input and the Crosstab output, i could see the order in which field are got in Crosstab is not in correct order. Please help me to solve this issue of how to Parse a Json file and get the same order as input json.

Hi, 

I have a simple question on transforming the data. This is the input format. 

Customer ID	Date	Product
1	11/16/2015	A
1	11/16/2015	B
1	11/16/2015	C
1	11/16/2015	D
1	11/16/2015	E
1	11/16/2015	E
1	11/16/2015	F

 

And I want to transform/transpose SKU from a column to a row, which will look like this. 

Customer	Date	Product 1	Product 2	Product 3	Product 4	Product 5	Product 6
1	11/16/2015	A	B	C	D	E	F

 

I am not so familiar with transpose functions so any help is much appreciated. 

 

Thanks,

Hello,

 

I need to convert strings (in my case countries) into unique code number.

I tried the function CharToInt, but it gives me identical numbers for different countries (for example 65 for australia, azerbaidjan, austria, argentina etc.).

Can someone explain me why ? Is there a solution to convert a string into a unique code ? 

 

Thank you

Hi,
I am trying to insert data in a MySQL database table which has a unique index on one of the columns.
Alteryx errors out because its trying to insert a duplicate value.

Update: Insert if new (Alteryx ) also does not seem to work.

Is there a way I can use the MySQL command 'replace into' or 'insert ignore into'.

I do not think the Pre / Post SQL statements can be used here.

thank you

Hi all,

 

Just wondering if there's a list somewhere of how to use the control characters (https://en.wikipedia.org/wiki/C0_and_C1_control_codes) within Alteryx, e.g., if a dataset is delimited by the SOH character, how would I specify this?

 

Thanks in advance,

So I've been given a pretty unorganized data set with a bunch of address info all in one column. I figured out how to parse out zip and state using ReverseString then a Text to Column. I having a much harder time getting the City and Address because as you can see the info is all over the place some having customer info and some having PO Boxes. 

 

I'm wondering if there is anyway I can parse out "city" by looking for patterns like parsing everything left of an two uppercase letters and right of everyword like "AVE, ST, LN, RD etc." Possible similar thing for address with parsing between "RD, ST etc" and a set of digits.

 

Not sure if thats possible but my goal was to eventually use the Alteryx geocoding app. Thanks for the help!

Hi,

 

I have a table like this

 

Client     Text

1            I like the product a lot

2            The product is expensive

...           ....

 

Now, I want to count the number of words for each row. So, I want to produce a new column like that:

 

Client     Text                                          Wordcount

1            I like the product a lot               6

2            The product is expensive         4

...           ....

 

Any idea how to do this?

Thanks a lot,

Looking for some help with a basic?

 

I have output from an execl pivot with two columns: Time and a number

In thh Time column there is a random date row to which all the time below it belongs. So would like Alteryx to look for random dates, create a new column, and transpose the file to a Date, Time, Number, format with times asigned to there propoer date:

So:

 

Time            Number

24;00:00      12

24:00:01      15

25/06/2016

06:00:00      56

Becomes:

Hi,

 

I'm trying to build a workflow to audit my TWB files and am running into an issue where the Calculation strings for some fields are being truncated without any apparent reason and I am unable to prevent it from happening.

 

Here's an example:

 

The XML contains the entire Calculation string...

 

 

When I connect the XML Parse tool to the Input Tool, the calculation_formula field is read in as a V_String with a size of 900.

 

 

I can change this to a V_WString and increase the Size, but that doesn't seem to do anything.  The values in certain fields are simply truncated.

 

 

I have to imagine that there is a way to ensure the entire string gets read in, but I am at a loss as to what that might be.

I want to read the tags marked with text from XML files that follow this pattern:

 

I have created a Talend Open Studio job that does this very well. However I obviously can't use the XPath-structure in Alteryx. I tried a few things, but nothing seems to work.

My biggest concern is that at the lowest level of AAAAB and AAAAC the field types can vary, so AAAAB has field 1 and field 2 types, but AAAAC has field 1 and field 3 types. These can't mix, I need to know exactly which field 1 is aligned with field 2 or field 3.

And I can't depict that relation in Alteryx.

 

My first try was this, where every parser reads a single child element. It keeps all the fields I want, unfortunately it creates lots of duplicates and no correct relations. Not to mention that it is inredibly slow because of the duplicates.

My second try was to parse every field individually, but I can't join these correctly, because I have no key fields with which to join the records. Matching by record order doesn't work because of the field 1/2 separation at the lowest level.

 

I hope my problem is understandable. I feel like I'm tackling this whole issue from the wrong perspective.
