[All Databricks Certified Data Analyst Associate Questions]

A data analyst has a managed table table_name in database database_name. They would now like to remove the table from the database and all of the data files associated with the table. The rest of the tables in the database must continue to exist.

Which of the following commands can the analyst use to complete the task without producing an error?

ADROP DATABASE database_name;

BDROP TABLE database_name.table_name;

CDELETE TABLE database_name.table_name;

DDELETE TABLE table_name FROM database_name;

EDROP TABLE table_name FROM database_name;

Show Suggested Answer

Suggested Answer: B

The DROP TABLE command removes a table from the metastore and deletes the associated data files. The syntax for this command is DROP TABLE [IF EXISTS] [database_name.]table_name;. The optional IF EXISTS clause prevents an error if the table does not exist. The optional database_name. prefix specifies the database where the table resides. If not specified, the current database is used. Therefore, the correct command to remove the table table_name from the database database_name and all of the data files associated with it is DROP TABLE database_name.table_name;. The other commands are either invalid syntax or would produce undesired results.Reference:Databricks - DROP TABLE

Surprised that people still mix up DROP and DELETE!

I thought DROP DATABASE would work, but it deletes everything!

Wait, isn't it DELETE TABLE instead?

The correct command is B, DROP TABLE database_name.table_name.

I’m pretty sure "DELETE TABLE" isn’t a valid command, but I can't recall the correct syntax for dropping a table.

I practiced a similar question, and I believe "DROP DATABASE" would remove everything, which isn't what we want here.

I think option B looks familiar, but I feel like there might be a specific way to reference the database and table.

I remember that to remove a table, we usually use the DROP TABLE command, but I'm not sure about the exact syntax.

This seems like a classic SQL question testing our knowledge of database management commands. I'll methodically go through each option and eliminate the incorrect ones until I'm left with the right answer.

I'm a little confused by the wording of the question. Is it asking for the command to drop just the table, or the entire database? I'll need to re-read it carefully before selecting an answer.

Okay, I've got this. The key is to use the DROP TABLE command with the fully qualified table name, including the database name. I'm confident option B is the right answer.

Hmm, I'm a bit unsure about this one. Dropping a whole database seems too extreme, but I'm not sure if the other options are correct. I'll have to think this through step-by-step.

This looks like a straightforward SQL question. I'll carefully read through the options and think about the correct syntax for dropping a table without affecting the rest of the database.

Alright, let me break this down. The key requirements are a full system backup that uses an insecure TCP-based protocol. I think option D, "Type: System Configuration" and "Protocol: TFTP", might be the best fit since TFTP uses TCP and is considered an insecure protocol.

Okay, I think I've got this. The key is to ensure the traffic is inspected without alerting the end-users. Option D seems like the best approach.

This looks like a tricky one. I'm a bit confused about how to apply the additive model to adjust the trend equation. I'll need to review my notes on that and make sure I understand the process before attempting to solve this.

For B, I remember discussing how insuring risks doesn't mean businesses can just ignore them; they still have to manage and mitigate those risks.
