Discuss Databricks Databricks Certified Data Analyst Associate Exam Topic 2 Question 33

Which of the following is a benefit of Databricks SQL using ANSI SQL as its standard SQL dialect?

AIt has increased customization capabilities

BIt is easy to migrate existing SQL queries to Databricks SQL

CIt allows for the use of Photon's computation optimizations

DIt is more performant than other SQL dialects

EIt is more compatible with Spark's interpreters
Databricks SQL uses ANSI SQL as its standard SQL dialect, which means it follows the SQL specifications defined by the American National Standards Institute (ANSI). This makes it easier to migrate existing SQL queries from other data warehouses or platforms that also use ANSI SQL or a similar dialect, such as PostgreSQL, Oracle, or Teradata.By using ANSI SQL, Databricks SQL avoids surprises in behavior or unfamiliar syntax that may arise from using a non-standard SQL dialect, such as Spark SQL or Hive SQL12.Moreover, Databricks SQL also adds compatibility features to support common SQL constructs that are widely used in other data warehouses, such as QUALIFY, FILTER, and user-defined functions2.Reference:ANSI compliance in Databricks Runtime,Evolution of the SQL language at Databricks: ANSI standard by default and easier migrations from data warehouses

Suggested Answer: E

The SQL Editor page is where the analyst can write and execute SQL queries in Databricks SQL. The SQL Editor page has a query pane where the analyst can type or paste SQL statements, and a results pane where the analyst can view the query results in a table or a chart. The analyst can also browse data objects, edit multiple queries, execute a single query or multiple queries, terminate a query, save a query, download a query result, and more from the SQL Editor page.Reference:Create a query in SQL editor

I thought Spark SQL was more compatible, this is surprising!

Customization capabilities are nice, but not the main benefit.

Josephine 11 months ago

Wait, is it really more performant than others?

Arlette 11 months ago

Totally agree, that’s a huge plus!

I vaguely remember something about how using ANSI SQL helps avoid surprises with syntax, which seems really important for smooth migrations.

Peggie 12 months ago

I feel like performance might be a factor too, but I can't recall if that's specifically tied to ANSI SQL or just Databricks in general.

Caprice 12 months ago

I remember practicing a question about SQL dialects, and I think compatibility with existing SQL queries was highlighted as a key advantage.

Gussie 1 year ago

I think the benefit of using ANSI SQL is that it makes migrating existing SQL queries easier, but I'm not entirely sure if that's the main point.

The fact that Databricks SQL uses ANSI SQL means it should be more compatible with other platforms and easier to integrate existing SQL code. That flexibility is a big benefit, so I'm leaning towards option B as the best answer.

Kimbery 1 year ago

I'm a little confused by all the technical details in the question. I'll need to re-read it a few times to make sure I understand the differences between the SQL dialects and how that impacts Databricks SQL. Hopefully, I can narrow it down from there.

Matthew 1 year ago

Okay, the key here is that ANSI SQL makes it easier to migrate existing SQL queries to Databricks SQL. That's really helpful for companies already using other data warehouses. I think option B is the way to go.

Pamella 1 year ago

Hmm, I'm a bit unsure about this one. I know ANSI SQL is a standard, but I'm not sure how that specifically benefits Databricks SQL. I'll need to think this through carefully.

This seems like a straightforward question about the benefits of Databricks SQL using ANSI SQL. I'm confident I can identify the correct answer.

I'm just glad Databricks SQL isn't speaking some made-up SQL dialect. ANSI SQL is the way to go, no doubt about it.

Stevie 1 year ago

The ANSI SQL standard is like the universal language of data. Databricks SQL speaking it fluently is a major plus in my book.
