SQL-WTF SQL-TIL snowflake edition.

In Snowflake, you can create tables, stages, and functions temporarily.
Temporary objects remain visible in the current session only and disappear after the session ends.

The unusual behavior is that you can create a temporary object with the same name as an already existing object.

So, all existing objects linked with it will be relinked to the "new" temporary object. For e.g. all views dependent on the original table will depend on the temporary table.

More than it!

The permanent table created after the temporary table with the same name stays invisible in the current session too :)
JUG Ru Group's SmartData is back!

The conference for data engineers will take place in October.

Would you like to give a talk there? If you have interesting cases or you want to share your experience of nontrivial solutions, apply for participation.

You will confirm your expertise, get to know other experts and get feedback from the participants. The Program Committee will help to prepare for the talk: schedule a personal curator, conduct a review of the material and organize rehearsals.

On the website, you will find a list of topics you can talk about. If you have another topic, send your suggestions; they will be considered.

And if you just want to participate in SmartData 2022, tickets are already on the website.

When you want to make sure your primary key is really really really unique (valid in PostgreSQL) by Lukas Eder
“Every decade, another hyped-up database technology comes along that claims SQL is terrible, slow, or impractical,” Pavlo says. “Over time, the conventional wisdom comes back to realizing that [SQL] is a good idea, and everyone returns to it.”
