CLR procedures are not enabled by default. You need to run the following queries to enable CLR:
sp_configure 'show advanced options', 1;

In addition, if some CLR module need external access, you should set TRUSTWORTHY pr...
The basic method to escape reserved words for SQL Server is the use of the square brackets ([ and ]). For example, Description and Name are reserved words; however, if there is an object using both as names, the syntax used is:
SELECT [Description]
FROM dbo.TableName
WHERE [Name] = 'foo'

Creating a new array is slightly confusing, as there is no real identifier for an array in awk. So, an array cannot really be initialised with our AWK code.
An array in awk is associative, meaning that any string or number can be a key. This means that the array is more like a key-value pair dictio...

const correctness is the practice of designing code so that only code that needs to modify an instance is able to modify an instance (i.e. has write access), and conversely, that any code that doesn't need to modify an instance is unable to do so (i.e. only has read access). This prevents the insta...
