It is recommended that you remove all special characters and HTML formatting. This task can be handled in TSQL code, however in this case I have the opportunity to use .NET and the power of the regular expressions to manage the string.

You need to generate random data directly into SQL Server table columns or close to the database engine as variables or expressions. Looking at the SQL Server available functions, you notice that only RAND function offers support for random data generation. Although RAND([seed]) is a built-in function, it can only return a float value between 0 and 1, and has other limitations in regards to seed values. Because your table columns may be of various data types, and each data type may have a lower value and an upper value, you would prefer to create your custom random data generators. This is when SQL Server CLR functions come into play and provide a viable solution.   Read more...
