Snowflake Certified SnowPro Specialty - Snowpark 認定 SPS-C01 試験問題 (Q278-Q283):

質問 # 278
You have a Snowpark DataFrame 'df with a column 'transaction_date' of STRING type, containing dates in 'YYYY-MM-DD' format, and a 'transaction_amount' column of STRING type, containing currency values like '$1 ,234.56'. You need to create a new DataFrame 'df_transformed' that contains the 'transaction_date' as a DATE type and 'transaction_amount' as a DOUBLE type. What Snowpark Python code snippet will accomplish this transformation most efficiently and handle potential errors during the cast?

A. ...python from snowflake.snowpark.functions import try_to_date, try_to_double df_transformed = df.with_column('transaction_date', try_to_date(col('transaction_date'))).with_column('transaction_amount', try_to_double(regexp_replace(col('transaction_amount'), '[$,]', ")))
B. ...python df_transformed = df.select(to_date(col('transaction_date')).alias('transaction_date'), to_double(col('transaction_amount')).alias('transaction_amount'))
C. ...python import snowflake.snowpark.functions as sf df_transformed = df.with_column('transaction_date', sf.to_date(sf.col('transaction_date'), format='YYYY- MM-DD')).with_column('transaction_amount', sf.to_double(sf.regexp_replace(sf.col('transaction_amount'), '[$,]', ")
D. ...python df_transformed = df.with_column('transaction_date', to_date(col('transaction_date'))).with_column('transaction_amount', to_double(col('transaction_amount').replace('$',").replace(',',")))
E. ...python df_transformed = df.with_column('transaction_date', to_date(col('transaction_date') YYYY-MM-DD')).with_column('transaction_amount', col('transaction_amount').cast(DoubleType()))

正解：A

解説：
Option C is the most robust because it uses and , which handle potential conversion errors by returning NULL instead of throwing exceptions. It also correctly uses 'regexp_replace' to remove both '$ and ',' from the 'transaction_amount' string before casting. Option A doesn't handle the format string for 'to_date' or special characters in amount. Option B doesnt remove special charcaters from transaction amount.Option D will not return other existing Columns, and also it doesn't handle the format string for 'to_date' or special characters in amount. Option E will not handle errors gracefully and redundantly imports 'snowflake.snowpark.functions as sf, and it also requires providing a format string for 'to_date' .

質問 # 279
You have two Snowpark DataFrames, 'dfl' and 'df2 , both containing customer data, but with slightly different schemas. 'dfl' has columns 'customer_id', 'name', and 'email'. 'df2' has columns 'id', 'customer name', and 'email_address'. You want to perform a set- based operation to find all unique customer IDs present in 'dfl but NOT in 'df2' , considering that 'customer_id' in 'dfl corresponds to 'id' in 'df2. Which of the following code snippets will achieve this, ensuring that column names are correctly aligned before the operation?

正解：D

解説：
Option D is the correct solution. First, 'customer_id')' renames the 'id' column in 'df2 to 'customer_id', aligning it with the 'customer_id' column in 'dfl Then, 'cifl performs the set difference operation, returning only the 'customer_id' values present in 'dfl& but not in the modified 'df2. 'exceptAll' (Option A) will include duplicates. Option B uses 'minus' which does not exist on Snowpark DataFrame. Options C uses 'subtract which also does not exist. Option E will cause unexpected results because the column name of dfl and df2 would be different.

質問 # 280
You need to create a Snowpark DataFrame using a SQL query. The query requires a user-defined variable (e.g., a date for filtering records). What are the correct and recommended ways to safely pass this variable into the SQL query when creating the DataFrame using 'session.sql()' to prevent SQL injection vulnerabilities?

正解：C、E

解説：
Options C and E are the safest and recommended approaches. Option C, if supported by your Snowpark version, uses parameterized SQL queries, which are the best way to prevent SQL injection. Option E avoids injecting the variable into the SQL string at all by filtering in Snowpark after the DataFrame is created. Options A and B are highly vulnerable to SQL injection. Option D is better than A and B, but still less secure and more complex than using parameterized queries or filtering with the DataFrame API.

質問 # 281
You are using VS Code with the Snowflake extension to develop a Snowpark application. You have successfully connected to your Snowflake account and are writing a script that creates a stage and then loads data from a local file into a Snowflake table using Snowpark. However, you're encountering issues with file paths and permission errors. Which of the following strategies would best address these challenges and ensure your Snowpark application can reliably load data from local files?

A. Use VS Code's remote development feature to run your Snowpark code directly on the Snowflake compute nodes. This will eliminate file path issues.
B. Utilize Snowpark's 'session.file.put' to upload the local file to an internal or external stage. Then, use 'session.table.copy_into' to load data from the stage into the target table.
C. Leverage a network share and mount it as a drive in both your local development environment and the Snowflake environment. Then, use relative file paths in your Snowpark code.
D. Modify the Snowflake account-level parameters to allow direct access to the local file system. Use relative file paths to access the local file.
E. Use absolute file paths in your Snowpark code when referring to local files. Ensure the Snowflake service account has read access to the local file system.

正解：B

解説：
Option B is the most secure and recommended approach. Snowflake's security model restricts direct access to local file systems. Using 'session.file.put' uploads the file to a Snowflake-managed stage (either internal or external), ensuring data is transferred securely and access is controlled within the Snowflake environment. Then, 'copy_into' safely loads the staged data into the table. The other options are problematic for these reasons: Option A is incorrect because Snowflake does not directly access the local file system for security reasons. Option C is overly complex and introduces external dependencies that can be difficult to manage and secure. Option D is incorrect as Snowflake does not allow modifications to account-level parameters to grant direct local file system access. This would be a major security risk. Option E is incorrect. VS Code's remote development is for connecting to remote servers; it cannot run code on Snowflake compute nodes.

質問 # 282
You are developing a Snowpark application to ingest a large dataset into Snowflake. You have a DataFrame with a schema that matches the target table 'TARGET TABLE. Due to network constraints, you need to optimize the insertion process to minimize the number of API calls. Which of the following approaches would provide the MOST efficient way to insert the data?

A. Directly use the method, without any intermediate transformations.
B. Stage 'data_df to an internal stage, then load the data from stage to the table using COPY INTO command.
C. Load the DataFrame into chunks of 1000 records into target table by using insert_into() function iteratively
D. Iterate through the rows of 'data_df , constructing and executing a separate INSERT statement for each row using 'session.sql()'.
E. Convert 'data_df to a Pandas DataFrame using and then use to insert the data.

正解：A

解説：
The most efficient approach is option C: 'data_df.insert_into('TARGET_TABLE')'. This method leverages Snowpark's optimized data transfer mechanisms and performs bulk insertion using the underlying Snowflake engine which minimizes api calls and faster to insert the data. Option A is highly inefficient due to the overhead of constructing and executing individual SQL statements. Option B introduces Pandas, which is slower. Option D involves additional staging steps. Option E is manual chunking which is also slower.
