import sqlalchemy
from sqlalchemy import Column, ForeignKey, Integer, String
from sqlalchemy.dialects import registry
from sqlalchemy.orm import backref, declarative_base, relationship, sessionmaker

Base = declarative_base()


class Artist(Base):
    __tablename__ = "artists"

    ArtistId = Column("ArtistId", Integer, primary_key=True)
    Name = Column("Name", String)
    Albums = relationship("Album", backref=backref("artist"))


class Album(Base):
    __tablename__ = "albums"

    AlbumId = Column("AlbumId", Integer, primary_key=True)
    ArtistId = Column("ArtistId", Integer, ForeignKey("artists.ArtistId"))
    Title = Column("Title", String)

# SQLite Cloud connection string
connection_string = "sqlitecloud://myhost.sqlite.cloud:8860/mydatabase.sqlite?apikey=myapikey"

engine = sqlalchemy.create_engine(connection_string)
Session = sessionmaker(bind=engine)
session = Session()

name = "John Doe"
query = sqlalchemy.insert(Artist).values(Name=name)
result_insert = session.execute(query)

title = "The Album"
query = sqlalchemy.insert(Album).values(
    ArtistId=result_insert.lastrowid, Title=title
)
session.execute(query)

query = (
    sqlalchemy.select(Artist, Album)
    .join(Album, Artist.ArtistId == Album.ArtistId)
    .where(Artist.ArtistId == result_insert.lastrowid)
)

result = session.execute(query).fetchone()

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/README.md

Demonstrates how to switch from using the standard sqlite3 library to sqlitecloud-py by changing the import statement and connection string. This example creates a table, inserts data, and then queries it.

```python
# import sqlitecloud
import sqlite3

# comment out the following line...
conn = sqlite3.connect(":memory:")

# ... and uncomment this line and import the sqlitecloud package
# (add the database name like in this connection string)
# conn = sqlitecloud.connect("sqlitecloud://myhost.sqlite.cloud:8860/mydatabase.sqlite?apikey=myapikey")

conn.execute("CREATE TABLE IF NOT EXISTS producers (ProducerId INTEGER PRIMARY KEY, name TEXT, year INTEGER)")
conn.executemany(
    "INSERT INTO producers (name, year) VALUES (?, ?)",
    [("Sony Music Entertainment", 2020), ("EMI Music Publishing", 2021)],
)

cursor = conn.execute("SELECT * FROM producers")

for row in cursor:
    print(row)
```

### Insert and Query DataFrame with SQLite Cloud

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/README.md

This snippet shows how to read data into a Pandas DataFrame, write it to a SQLite Cloud database, and then query the database to fetch data back into a DataFrame. Ensure you have pandas and sqlitecloud libraries installed.

```python
import io

import pandas as pd

import sqlitecloud

dfprices = pd.read_csv(
    io.StringIO(
        """DATE,CURRENCY,PRICE
    20230504,USD,201.23456
    20230503,USD,12.34567
    20230502,USD,23.45678
    20230501,USD,34.56789"""
    )
)

conn = sqlitecloud.connect("sqlitecloud://myhost.sqlite.cloud:8860/mydatabase.sqlite?apikey=myapikey")

conn.executemany("DROP TABLE IF EXISTS ?", [("PRICES",)])

# Write the dataframe to the SQLite Cloud database as a table PRICES
dfprices.to_sql("PRICES", conn, index=False)

# Create the dataframe from the table PRICES on the SQLite Cloud database
df_actual_prices = pd.read_sql("SELECT * FROM PRICES", conn)

# Inspect the dataframe
print(df_actual_prices.head())

# Perform a simple query on the dataframe
query_result = df_actual_prices.query("PRICE > 50.00")

print(query_result)
```

--------------------------------

### Execute INSERT and SELECT Queries with Parameter Styles

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/samples.ipynb

Demonstrates executing INSERT and SELECT queries using both question mark (?) and named (:name) parameter styles for safe query preparation. This helps prevent SQL injection.

```python
# You can use the cursor to perform other queries.
# Queries can be prepared with `question mark` and `named` style
cursor = conn.execute("INSERT INTO genres (Name) values (?)", ("My brand new genre",))

cursor.execute("SELECT * FROM genres WHERE Name like :name", {"name": "My brand%"})

cursor.fetchone()
```

--------------------------------

### Select Database for Queries

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/samples.ipynb

If the database was not specified in the connection string, you can select it using the 'USE DATABASE' SQL command. This ensures subsequent queries target the correct database.

```python
# Select the database to use if not specified in the connection string
db_name = "chinook.sqlite"
conn.execute(f"USE DATABASE {db_name}")
```

--------------------------------

### Connect to SQLite Cloud and Query Data

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/README.md

Connect to a SQLite Cloud instance using a connection string and API key. Demonstrates executing a query and fetching a single result.

```python
import sqlitecloud

# Open the connection to SQLite Cloud
conn = sqlitecloud.connect("sqlitecloud://myhost.sqlite.cloud:8860?apikey=myapikey")

# You can autoselect the database during the connect call
# by adding the database name as path of the SQLite Cloud
# connection string, eg:
# conn = sqlitecloud.connect("sqlitecloud://myhost.sqlite.cloud:8860/mydatabase?apikey=myapikey")
db_name = "chinook.sqlite"
conn.execute(f"USE DATABASE {db_name}")

cursor = conn.execute("SELECT * FROM albums WHERE AlbumId = ?", (1, ))
result = cursor.fetchone()

print(result)

conn.close()
```

--------------------------------

database name as path of the SQLite Cloud connection string, eg:
# conn = sqlitecloud.connect("sqlitecloud://myhost.sqlite.cloud:8860/mydatabase?apikey=myapikey")
sqlitecloud_connection_string = "sqlitecloud://myhost.sqlite.cloud:8860/mydatabase?apikey=myapikey"

# Open the connection to SQLite Cloud
conn = sqlitecloud.connect(sqlitecloud_connection_string)
```

--------------------------------

### Execute SELECT Query and Fetch One Row

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/samples.ipynb

Execute a SELECT query to retrieve data. The result is a Cursor object from which you can fetch rows. fetchone() retrieves a single row.

```python
# The execution of the query generate the `Cursor` object
# to fetch the results.
cursor = conn.execute("SELECT * FROM albums")
cursor.fetchone()
```

--------------------------------

### SQLAlchemy ORM with SQLite Cloud

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/README.md

Defines SQLAlchemy ORM models for 'artists' and 'albums' tables and demonstrates inserting and querying data using a SQLite Cloud connection string. Ensure your connection string is correctly formatted with your host, port, database name, and API key.

```python
import sqlalchemy
from sqlalchemy import Column, ForeignKey, Integer, String
from sqlalchemy.dialects import registry
from sqlalchemy.orm import backref, declarative_base, relationship, sessionmaker

Base = declarative_base()


class Artist(Base):
    __tablename__ = "artists"

    ArtistId = Column("ArtistId", Integer, primary_key=True)
    Name = Column("Name", String)
    Albums = relationship("Album", backref=backref("artist"))


class Album(Base):
    __tablename__ = "albums"

    AlbumId = Column("AlbumId", Integer, primary_key=True)
    ArtistId = Column("ArtistId", Integer, ForeignKey("artists.ArtistId"))
    Title = Column("Title", String)

# SQLite Cloud connection string
connection_string = "sqlitecloud://myhost.sqlite.cloud:8860/mydatabase.sqlite?apikey=myapikey"

engine = sqlalchemy.create_engine(connection_string)
Session = sessionmaker(bind=engine)
session = Session()

name = "John Doe"
query = sqlalchemy.insert(Artist).values(Name=name)
result_insert = session.execute(query)

title = "The Album"
query = sqlalchemy.insert(Album).values(
    ArtistId=result_insert.lastrowid, Title=title
)
session.execute(query)

query = (
    sqlalchemy.select(Artist, Album)
    .join(Album, Artist.ArtistId == Album.ArtistId)
    .where(Artist.ArtistId == result_insert.lastrowid)
)

result = session.execute(query).fetchone()

print("Artist Name: " + result[0].Name)
print("Album Title: " + result[1].Title)

```

query_result = df_actual_prices.query("PRICE > 50.00")

print(query_result)
```

--------------------------------

### Pandas DataFrame Integration with SQLite Cloud

Source: https://github.com/sqlitecloud/sqlitecloud-py/blob/main/samples.ipynb

Use Pandas DataFrames to easily load data from CSV into SQLite Cloud and query data from SQLite Cloud into DataFrames. This simplifies data manipulation and analysis workflows.

```python
import io

import pandas as pd

import sqlitecloud

dfprices = pd.read_csv(
    io.StringIO(
        """DATE,CURRENCY,PRICE
    20230504,USD,201.23456
    20230503,USD,12.34567
    20230502,USD,23.45678
    20230501,USD,34.56789"""
    )
)

conn = sqlitecloud.connect(sqlitecloud_connection_string)

conn.executemany("DROP TABLE IF EXISTS ?", [("PRICES",)])

# Write the dataframe to the SQLite Cloud database as a table PRICES
dfprices.to_sql("PRICES", conn, index=False)

# Create the dataframe from the table PRICES on the SQLite Cloud database
df_actual_prices = pd.read_sql("SELECT * FROM PRICES", conn)

# Inspect the dataframe
print(df_actual_prices.head())
```

--------------------------------

### Close SQLite Cloud Connection
