Search Databases and Tables in Apache Hive

In all SQL supported systems, the LIKE operator is used in the WHERE clause of a query statement to search for a specified pattern in a column.

But what if we need to find a certain table or database?

Users will mostly have an option to search for a specific table or database in most database graphical user interfaces (GUIs). For example, in SQL Server Management Studio, you can filter in the objects explorer for a table/ database based on keywords. But it’s more challenging when it comes to CLIs. Listing all of the tables and databases may not always be the best solution. Apache Hive includes a capability that can assist us in finding the table/database using wildcards with LIKE operator.

SHOW DATABASES command will list out all the databases and SHOW TABLES will list out all the tables in the database. However, in order to filter, use the following :

The above command will return any databases with the word ‘sales’ in their name. Similarly,
will return all the tables that are having ‘test’ in their name.
