[All ARA-R01 Questions]

A table, EMP_ TBL has three records as shown:

The following variables are set for the session:

Which SELECT statements will retrieve all three records? (Select TWO).

Show Suggested Answer Hide Answer
Suggested Answer: B, E

The correct answer is B and E because they use the correct syntax and values for the identifier function and the session variables.

The identifier function allows you to use a variable or expression as an identifier (such as a table name or column name) in a SQL statement. It takes a single argument and returns it as an identifier. For example, identifier($tbl_ref) returns EMP_TBL as an identifier.

The session variables are set using the SET command and can be referenced using the $ sign. For example, $var1 returns Name1 as a value.

Option A is incorrect because it uses Stbl_ref and Scol_ref, which are not valid session variables or identifiers. They should be $tbl_ref and $col_ref instead.

Option C is incorrect because it uses identifier<Stbl_ref>, which is not a valid syntax for the identifier function. It should be identifier($tbl_ref) instead.

Option D is incorrect because it uses Cvarl, var2, and var3, which are not valid session variables or values. They should be $var1, $var2, and $var3 instead.Reference:

I’m confused about the use of IN with the variables. I thought it was supposed to match the exact names, so maybe A and E are the right picks?

I'm leaning towards C and D, but I can't recall if the identifier function works the same way in both cases.

I remember practicing a similar question, and I feel like option E could be a good choice too, but I need to double-check the variable names.

This is a tricky one, but I'm going to carefully analyze each option and try to match them to the given data. I may need to do some additional research on the syntax, but I'm determined to get this right.

I'm feeling pretty confident about this one. I just need to make sure I'm using the right identifiers and variable references in the query. I think options B and E are the correct answers.

Okay, I think I've got this. The key is to use the correct table and column names based on the information provided. Options B and E look the most promising to me.

Hmm, I'm a bit confused by the different table and column references in the options. I'll need to double-check the syntax and make sure I understand how the variables are being used.

This looks like a straightforward SQL query question. I'll need to carefully read through the options and match them to the given table and variables.

I've got this! First, I'll get the list of all ready nodes with `kubectl get nodes -o jsonpath='{range .items[*]}{@.metadata.name}{" "}{@.status.conditions[?(@.type=="Ready")].status}{"\n"}{end}'`. Then I'll filter out the tainted nodes with `kubectl get nodes -o jsonpath='{range .items[*]}{@.metadata.name}{" "}{@.spec.taints[?(@.effect=="NoSchedule")].key}{"\n"}{end}'`. Finally, I'll write the count to the file with `echo $(( $(wc -l < /tmp/ready_nodes.txt) - $(wc -l < /tmp/tainted_nodes.txt) )) > /opt/KUSC00402/kusc00402.txt`.

I've got a good strategy for this. I'll start by considering the bandwidth capabilities of the FC switches and the VSP G200 ports. Then I'll think about how the host HBA and multi-pathing software could impact performance.

Hmm, I'm not sure. The question mentions storing files, videos, and virtual disk images, so a key-value store might also work well for that type of unstructured data.

I agree with E, and I believe B could also be correct since it uses 'identifier(Scol_ref)'.
