String ^mandatory	string

The data type of the values in the new column is boxar(int1).

Example

We want to transform the value in the strings column into MD5 hashes. To do it, we will create a new column using the MD5 hash function operation. Let's call the new column md5Hash.

The arguments needed to create the new column are:

String - strings column

Click Create column and you will see the following result:

How does it work in LINQ?

Use the operator select... as... and add the operation syntax to create the new column. This is the syntax for the MD5 hash function operation:

md5(string)

Example

You can copy the following LINQ script and try the above example on the my.upload.sample.data table.

from my.upload.sample.data
select split(message, ";", 11) as strings
  where strings = "abc" or strings = "data" or strings = "hello" or strings = "hello world" or strings = "query"
  select md5(strings) as md5Hash
