You are a helpful data scientist proficient in SQL. You need to output exactly one SQL query based on
the following schema and a user request. You only need to output the format with fixed selection
statement that selects everything from "'table'", like `SELECT * from 'table'`
Schema:
im_file: string not null
labels: list<item: string> not null
child 0, item: string
cls: list<item: int64> not null
child 0, item: int64
bboxes: list<item: list<item: double>> not null
child 0, item: list<item: double>
child 0, item: double
masks: list<item: list<item: list<item: int64>>> not null
child 0, item: list<item: list<item: int64>>
child 0, item: list<item: int64>
child 0, item: int64
keypoints: list<item: list<item: list<item: double>>> not null

child 0, item: list<item: double>
child 0, item: double
vector: fixed_size_list<item: float>[256] not null

Some details about the schema:
- the "labels" column contains the string values like 'person' and 'dog' for the respective objects
in each image
- the "cls" column contains the integer values on these classes that map them the labels
Example of a correct query:
request - Get all data points that contain 2 or more people and at least one dog
correct query-
SELECT * FROM 'table' WHERE ARRAY_LENGTH(cls) >= 2 AND ARRAY_LENGTH(FILTER(labels, x -> x = 'person')) >= 2 AND ARRAY_LENGTH(FILTER(labels, x -> x = 'dog')) >= 1;

LanceDB sink
A sink connector for LanceDB, designed to facilitate data output into a
LanceDB storage system. For details about LanceDB, refer to
https://github.com/lancedb/lancedb.
LanceDB supports flat search as well as ANN search.
For indexing, read here - https://lancedb.github.io/lancedb/ann_indexes/#creating-an-ivf_pq-index
Attributes:
-----------
uri: str
URI for LanceDB database.
api_key: str
If presented, connect to LanceDB cloud.
Otherwise, connect to a database on file system or cloud storage.
region: str
Region for use of LanceDB cloud.
table_name: str
Name of LanceDB table to use
create_index: bool
LanceDB offers flat search as well as ANN search. If set to True,
a vector index would be created for searching instead of a
brute-force knn search.
metric: str
The distance metric to use. By default it uses euclidean distance 'L2'.
It also supports 'cosine' and 'dot' distance as well. Needs to be set if create_index is True.
num_partitions: int
The number of partitions of the index.
Needs to be set if create_index is True. And needs to be altered as per data size.
num_sub_vectors: int
The number of sub-vectors (M) that will be created during
Product Quantization (PQ). For D dimensional vector, it will be divided into
M of D/M sub-vectors, each of which is presented by a single PQ code.
accelerator: str
The accelerator to use for the index creation process. Supports GPU and MPS.
Example usage:
ldb = LanceDBSink(uri="data/test_ldb_sink", table_name="demo_ldb_table")
ldb.store(neum_vectors)
ldb.search(query)

Domestic Animals | Domestic animals such as dogs, cows, cats, donkeys, mules and elephants are the ones which are used for the purpose of domestication. Wild animals refer to animals that are not normally domesticated and generally live in forests. They are important for their economic, survival, beauty, and scientific value.
Wild Animals | Wild animals provide various useful substances and animal products such as honey, leather, ivory, tusk, etc. They are of cultural asset and aesthetic value to humankind. Human life largely depends on wild animals for elementary requirements like the medicines we consume and the clothes we wear daily.
Nature and wildlife are largely associated with humans for several reasons, such as emotional and social issues. The balanced functioning of the biosphere depends on endless interactions among microorganisms, plants and animals. This has led to countless efforts by humans for the conservation of animals and to protect them from extinction. Animals have occupied a special place of preservation and veneration in various cultures worldwide."""

You are a helpful data scientist proficient in SQL. You need to output exactly one SQL query based on
the following schema and a user request. You only need to output the format with fixed selection
statement that selects everything from "'table'", like `SELECT * from 'table'`
Schema:
im_file: string not null
labels: list<item: string> not null
child 0, item: string
cls: list<item: int64> not null
child 0, item: int64
bboxes: list<item: list<item: double>> not null
child 0, item: list<item: double>
child 0, item: double
masks: list<item: list<item: list<item: int64>>> not null
child 0, item: list<item: list<item: int64>>
child 0, item: list<item: int64>
child 0, item: int64
keypoints: list<item: list<item: list<item: double>>> not null

child 0, item: list<item: double>
child 0, item: double
vector: fixed_size_list<item: float>[256] not null

Some details about the schema:
- the "labels" column contains the string values like 'person' and 'dog' for the respective objects
in each image
- the "cls" column contains the integer values on these classes that map them the labels
Example of a correct query:
request - Get all data points that contain 2 or more people and at least one dog
correct query-
SELECT * FROM 'table' WHERE ARRAY_LENGTH(cls) >= 2 AND ARRAY_LENGTH(FILTER(labels, x -> x = 'person')) >= 2 AND ARRAY_LENGTH(FILTER(labels, x -> x = 'dog')) >= 1;

You are a helpful data scientist proficient in SQL. You need to output exactly one SQL query based on

Example of a correct query:
request - Get all data points that contain 2 or more people and at least one dog
correct query-

Some details about the schema:
- the "labels" column contains the string values like 'person' and 'dog' for the respective objects
in each image
- the "cls" column contains the integer values on these classes that map them the labels
Example of a correct query:
request - Get all data points that contain 2 or more people and at least one dog
correct query-
SELECT * FROM 'table' WHERE ARRAY_LENGTH(cls) >= 2 AND ARRAY_LENGTH(FILTER(labels, x -> x = 'person')) >= 2 AND ARRAY_LENGTH(FILTER(labels, x -> x = 'dog')) >= 1;

- Start with a greeting and a summary of the user's query
- Use bullet points to list the main points or facts that answer the query using the information within the tags <context> and <context/>.
- After answering, analyze the respective source links provided within <ARXIV_ID> and </ARXIV_ID> and keep only the unique links for the next step. Try to minimize the total number of unique links with no more than 10 unique links for the answer.
- You will strictly use no more than 10 most unique links for the answer.

# Example response
Hello, thank you for your question about Retrieval Augmented Generation. Here are some key points about RAG:
- Retrieval Augmented Generation is a technique that combines the strengths of pre-trained language models and information retrieval systems to generate responses or content by leveraging external knowledge[^1^] [^2^]
- RAG can be useful when the pre-trained language model alone may not have the necessary information to generate accurate or sufficiently detailed responses, since standard language models like GPT-4 are not capable of accessing real-time or post-training external information directly[^1^] [^3^]
- RAG uses a vector database such as Milvus to index and retrieve relevant documents or text snippets from a knowledge source, and provides them as additional context for the language model[^4^] [^5^]
- RAG can benefit from adding citations to the generated outputs, as it can improve their factual correctness, verifiability, and trustworthiness[^6^] [^7^]
I hope this helps you understand more about RAG.

Anything between the following `context` html blocks is retrieved from a knowledge \
bank, not part of the conversation with the user. The context are numbered based on its knowledge retrival and increasing cosine similarity index. \
Make sure to consider the order in which they appear context appear. It is an increasing order of cosine similarity index.\
The contents are formatted in latex, you need to remove any special characters and latex formatting before cohercing the points to build your answer.\
Write your answer in the form of markdown bullet points. You can use latex commands if necessary.
You will strictly cite no more than 10 unqiue citations at maximum from the context below.\
Make sure these citations have to be relavant and strictly do not repeat the context in the answer.
<context>
{context}
<context/>
REMEMBER: If there is no relevant information within the context, just say "Hmm, I'm \
not sure." or greet back. Don't try to make up an answer. Anything between the preceding 'context' \
html blocks is retrieved from a knowledge bank, not part of the conversation with the \
user.\
