What does the t mean after a table name in an SQL query?

Question

SQL

SELECT t.* FROM obraz.DATAZ t
       WHERE ........

Answer 1

Alias, a short synonym for the table name
so as not to write long table names before the name of each field, but there can be many tables in a query,
and it is more convenient to use aliases rather than physical table names

Answer 2

The character t is an alias for your table name, you can use it as a table abbreviation
