#Code Snippet

This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:

This article is little explanation to a GitGub project.

Now, let’s say you can’t access the terminal or simply you just rather execute it from a web interface. In this article, I will show you how to execute terminal commands from a simple web page.

For example, in the image below you see how we execute $zv on a webpage:

Hi all,

I've been looking for a way to extract the sorting from the ^CacheTemp.zenData global that contain the tablePane snapshot data in order to use it on a report following the current UI sorting criteria.

I could see that if the column is sorted by one column, new entries with this structure are created:

^CacheTemp.zenData(<sessionId>,<snapShotId>,<tablePaneId>,"index",<columnId>,<value>,<dataId>)=""

Hello,

Here's the code:

What's the best way to replace character groups?

I want not to remove character groups as $zstrip does but to replace them with whitespaces.

$translate needs explicit character list.

Effectively I want to remove any characters besides letters, numbers and a small (known) subset of punctuation characters, replacing everything else with whitespaces.

I'm writing some custom functions for use in a routing rule. I have a few that are working, but right now I'm trying to use one that has no parameters. Typically this would be a sub instead of a function, but I'm not familiar enough with Cache to know what I need to do here.

Here is the code:

We have in DB two books, first is loaned because it has the Friend ID, and the other is in the shelf.

I execute a class query to get all loaned books:

Query BooksLoaned() As %SQLQuery
{
SELECT *
FROM Library.Book
WHERE Friend IS NOT NULL
}

Which I have tested throught the portal:

Two fairly common requests we receive from HL7 customers are (1) how to remove all trailing delimiters for fields and segments in HL7 messages and (2) how to "find and replace" for an entire HL7 message (as opposed to one segment/field at a time). The code sample below shows a custom function that solves for item 1 and by extension item 2 above. In other words the same approach can be used for finding/replacing any sequence of chars in an entire HL7 message, with some tweaks to the custom function.

DTL Transformations and GetValueAt/SetValueAt calls on HL7 messages will truncate any fields longer than 32K. To avoid this, the methods GetFieldStreamRaw and StoreFieldStreamRaw must be used when dealing with fields that might be larger than 32K. OBX:5 is a frequent example. These methods have some subtleties and must be used carefully.

This can't be done by simply dragging from left to right in a DTL. It must be done with a code action. Also, the StoreFieldStreamRaw call must be the last edit made to the segment because the segment becomes immutable after that.

Hello Everyone,

I was wondering about the best way to initialize several variables, or several lists of variables.

Would it be better to write it like:

set (var1, var2, var3) = "value1"
set (var4, var5) = "value2"
set (var6,var7,var8) = "value3"

or

set var1="value1", var2="value1", var3="value1", var4="value2", var5="value2", var6="value3", var7="value3", var8="value3"

or

End users sure love Excel tables. So, how can you deliver the second to the first? Read this post to find out.

I've been trying to write a method to compare two local variables, which may be arrays, for "equality" - that is, to see if they have all the same subscripts (if they're arrays) and values. This is the best I've come up with so far - are there any better/simpler approaches out there?

Hi folks,

I've created a datatype class whoch extends from %Library.String with a REGEX parameter and the validation of the value against the regular expression. The class does not support Populate using the regular expression as a template for data population.
