Snowflake SnowPro Certification Practice Test

Which command can users utilize to retrieve the query ID of the second query executed in the current session?

1. GET second_query_id()

2. SELECT second_query_id()

3. SHOW last_query_id(2)

4. SELECT last_query_id(2)

The correct answer is: SELECT last_query_id(2)

The command that allows users to retrieve the query ID of the second query executed in the current session is structured to utilize the SELECT statement in conjunction with the function designed for this purpose. The correct answer involves using the SELECT statement, which indicates that the system is expected to return a value to the user, in this case, the query ID. The function last_query_id(2) specifically looks into the execution history for the current session and retrieves the ID corresponding to the second query that was executed. By using SELECT, you are explicitly asking Snowflake to return the result of that function, making it clear that the intention is to retrieve data, which fits the structure of SQL commands typically used for data selection. In contrast, other command structures provided in the options do not conform to this requirement, as they either do not utilize the correct SQL syntax needed to return a value or refer to functions that do not exist in the Snowflake context. For example, GET and SHOW are not used in combination with last_query_id in a manner that would return a specific query ID as intended. Therefore, SELECT last_query_id(2) is the correct choice for this scenario.
