    In our last post, we discussed the most basic of all ways how in Snowflake you can send out a basic email. It was pretty simple, straight text – nothing to really grab the attention of our readers – which we know is the way to craft an email, right? To do this, we’re going…

    To send an email in SQL Server, all that’s required is a fairly simple call of a stored procedure created by Microsoft. Now, there are several more parameters you can use. Below are some of my favorites that I use often. For the many other parameters you can use with sp_sendmail, please refer to the…

    Today, I want to talk about all the effort that goes into setting up the ability to email in SQL Server and Snowflake. First is our old friend – SQL Server. I’ll leave this one to the experts at Microsoft. As has been the case over the last few years, they have some great documentation…

    In our last post, we discussed data masking and setting it up for specific columns. Now, I don’t know about y’all, but I deal with hundreds of tables with several columns in each on a daily basis that truly need data masking. If I have to go through and set up a masking policy one…

    The premise behind data masking is fairly simple – make it so that only certain people can see the data in a certain column. For example, social security numbers or credit card numbers probably shouldn’t be seen by everyone who has access to your database. I like to set it up as follows: (Obviously, this…

    If you’ve been working with data for several years like I have – mostly using the SQL language – then I have a term for you that other languages, like JavaScript or Python, have had for a few years. The term is “memoizable” and it means, in a nutshell, to remember. A memoizable function caches…

    When working with one of the many modern computer languages that use libraries, one of the many things to be aware of – as a developer – is the version of the libraries available for your usage. Since there are multiple languages in Snowflake that use libraries, let’s go over how to check out the…

    This week, I want to talk about something we’ve all done at least once – especially before our first cup of coffee in the morning. Yes, that’s right – dropping tables and databases. So we have our table from last time still existing in our database: We’re trying to get rid of a table from…

    In my last post, we worked out how to change the data type of a field if it already existed and was found to need changing. This time, I want to add a fresh, new column to an existing table. In SQL Server, I would be doing something like the following. This works great if…

    When working with data, I usually have an idea of what type of data I will push into a field. Sometimes, for whatever reason, it is decided to change the type of data allowed in the field. Today, I want to show how that’s done in Snowflake. I will start out working with a simple…
