 ## Using AzureSQL Query Editor to Query and Export Data
-If you are using an AzureSQL Database, you can use the Query Editor to run SQL queries to retrieve desired data. Memory labels (`labels`) may be an especially useful column to query on for finding data pertaining to a specific operation, user, harm_category, etc. Memory labels are a free-from dictionary for tagging prompts with whatever information you'd like (e.g. `op_name`, `username`, `harm_category`). (For more information on memory labels, see the [Memory Labels Guide](../memory/5_memory_labels.ipynb).) An example is shown below:

 1. Write a SQL query in the Query Editor. You can either write these manually or use the "Open Query" option to load one in. The image below shows a query that gathers prompt entries with their corresponding scores for a specific operation (using the `labels` column) with a "float_scale" `score_type`.

+# # 5. Memory Labels and Advanced Memory Queries
+#
+# This notebook covers two ways to filter and retrieve data from PyRIT's memory:
+#
+# 1. **Memory Labels** — free-form key/value tags attached to every prompt, useful for grouping and retrieval.
+# 2. **Identifier Filters** — structured filters that match against the JSON-backed identifier columns
+#    (target, converter, scorer, attack) stored alongside different memory entities, such as `MessagePiece`, `AttackResult`, etc. 
+#    This notebook demonstrates the functionality with `MessagePiece` entities, but the concepts are similar for other memory entities.
+# 3. **Score Identifier Filters** — the same `IdentifierFilter` mechanism applied to `memory.get_scores()` for
+#    retrieving scores by scorer identity (class name, custom parameters, etc.).
+#
+# ## Part 1 — Memory Labels
+#
+# Memory labels are a free-form dictionary for tagging prompts for easier querying and scoring later on. The `GLOBAL_MEMORY_LABELS`
+# environment variable can be set to apply labels (e.g. `operator` and `operation`) to all prompts sent by any attack.
+# Passed-in labels will be combined with `GLOBAL_MEMORY_LABELS` into one dictionary. In the case of collisions,
+# the passed-in labels take precedence.
+#
+# You can then query the database (either AzureSQL or SQLite) for prompts with specific labels, such as `operator` and/or `operation`
+# (which are standard), as well as any others you'd like, including `harm_category`, `language`, `technique`, etc.
+#
+# We take the following steps in Part 1:
+# 1. Send prompts to a text target using `PromptSendingAttack`, passing in `memory_labels` to the execution function.
+# 2. Retrieve these prompts by querying for the corresponding memory label(s).
+# 3. Resend the retrieved prompts.

+# ## Part 2 — Identifier Filters
+#
+# Every `MessagePiece` stored in memory carries JSON identifier columns for the **target**, **converter(s)**, and
+# **attack** that produced it. `IdentifierFilter` lets you query against these columns without writing raw SQL.
+#
+# An `IdentifierFilter` has the following fields:
+#
+# | Field | Description |
+# |---|---|
+# | `identifier_type` | Which identifier column to search — `TARGET`, `CONVERTER`, `ATTACK`, or `SCORER`. |
+# | `property_path` | A JSON path such as `$.class_name`, `$.endpoint`, `$.model_name`, etc. |
+# | `value` | The value to match. |
+# | `partial_match` | If `True`, performs a substring (LIKE) match. |
+# | `array_element_path` | For array columns (e.g. converter_identifiers), the JSON path within each element. |
+#
+# The examples below query against data already in memory from Part 1.

+
+# %% [markdown]
+# ### Filter by converter (array column)
+#
+# Converter identifiers are stored as a JSON **array** (since a prompt can pass through multiple converters).
+# Use `array_element_path` to match if *any* converter in the list satisfies the condition.
+

+# %% [markdown]
+# ### Mixing labels and identifier filters
+#
+# Labels and identifier filters can be used together. Labels narrow by your custom tags,
+# while identifier filters narrow by the infrastructure (target, converter, etc.) that
+# handled each prompt.
+
+# %%
+# Retrieve prompts from our labeled group that specifically went through Base64Converter

+
+# %% [markdown]
+# ## Part 3 — Filtering Scores by Scorer Identity
+#
+# `IdentifierFilter` also works with `memory.get_scores()`. Every `Score` stored in memory records the
+# **scorer's identifier** — a JSON object that contains the class name as well as any custom parameters
+# the scorer was initialized with.
+#
+# In this example we create two `SubStringScorer` instances with different substrings, score the
+# assistant responses from Part 1, and then use `identifier_filters` on `memory.get_scores()` to
+# retrieve only the scores produced by a specific scorer.
+
+# %%
+from pyrit.models import Message
+from pyrit.score import SubStringScorer
+
+# Create three scorers with different substrings
+scorer_molotov = SubStringScorer(substring="molotov")
+scorer_launder = SubStringScorer(substring="launder")
+scorer_assist = SubStringScorer(substring="assist")  # intentionally bad scorer that matches when the phrase 'assist' is present in response. But good for demo.

+# Retrieve assistant responses from Part 1
+assistant_pieces = memory.get_message_pieces(

+)

+# Wrap each piece in a Message so we can pass it to score_async
+assistant_messages = [Message([piece]) for piece in assistant_pieces]

+# Score every response with both scorers — scores are automatically persisted in memory
