What is the SQL code that can be used to create a database table to store field report information for observations of White-tailed deer? The table should include columns for:
- Date and time of observation
- Location of observation
- Description of the environment and weather conditions at the time of observation
- Detailed description of the observed White-tailed deer, including size, behavior, and any notable physical characteristics
- Any other relevant observations or notes about the observation
Additionally, can you provide the SQL code to insert a new observation record into the table and retrieve all observations in the table? Finally, how can the retrieved observations be exported as a PDF file?

Sure, I'd be happy to help with these SQL queries.

**Table Creation Query:**

Assuming you want to create the table within a specific database, you'd use the following SQL query:

```sql
CREATE DATABASE database_name; -- Replace 'database_name' with your desired database name.

USE database_name; -- Switch to the newly created database.

-- Create a new table called 'observations'.
CREATE TABLE observations (
    observation_id INT PRIMARY KEY,
    date_time DATETIME,
    observation_location VARCHAR(255),
    environment_description VARCHAR(255),
    weather_description VARCHAR(255),
    white_tailed_deer_description VARCHAR(255),
    other_observations_description TEXT
);
```

**Row Insertion Query:**

Assuming this query is executed inside the `observations` table from the previous query, you'd use the following SQL query:

```sql
INSERT INTO observations (date_time, observation_location, environment_description, weather_description, white_tailed_deer_description, other_observations_description)
VALUES ('2022-01-01 19:30:00', 'Some Location', 'Description of environment', 'Weather description', 'Description of the deer', 'Other observation notes');
```

**All Observations Retrieval Query:**

Assuming this query is executed inside the `observations` table, you'd use the following SQL query to retrieve all rows:

```sql
SELECT * FROM observations;
```

**Exporting to PDF:**

Exporting data to PDF is typically achieved using a third-party tool or application and not directly in SQL. You'll need to use a programming language, such as Python or PHP, to generate the PDF. Alternatively, a report-generating tool like Crystal Reports can be used to generate PDFs, but that requires a separate installation and setup.

In Python, you could use the `reportlab` library to generate integrated PDFs. Here's an example of exporting a table from pandas dataframe to pdf.

Example in Python using Reportlab:

```python
from reportlab.lib.pagesizes import portrait, A4
from reportlab.lib.colors import HexColor
import pandas as pd
from reportlab.pdfgen import canvas
from reportlab.pdfreader import pdfreader

# Creating a PDF Canvas
pdf_canvas = canvas.Canvas("white_tailed_deer.pdf", pagesize=portrait(A4), bottomup=0)
pdf_canvas.setPage(0, landscape=1)
pdf_canvas.drawCentredString(A4[0]/2, A4[1]/2, 'White-tailed Deer Observation Report')
pdf_canvas.drawString(25, 700, 'Observation ID')
pdf_canvas.drawString(100, 700, 'Date & Time')
pdf_canvas.drawString(25, 650, 'Location')
pdf_canvas.drawString(100, 650, 'Environment')
pdf_canvas.drawString(25, 600, 'Weather')
pdf_canvas.drawString(100, 600, 'Deer Description')
pdf_canvas.drawString(25, 550, 'Observations')

# Dataframe
df = pd.read_sql_query("SELECT * FROM observations", "database_name")

# Table Style
pdf_canvas.setFont("Calibri", 12)
pdf_canvas.drawString(10, 500, "Observations")
pdf_canvas.drawString(100, 500, "Date & Time")
pdf_canvas.drawString(200, 500, "Location")
pdf_canvas.drawString(300, 500, "Environment")
pdf_canvas.drawString(400, 500, "Weather")
pdf_canvas.drawString(500, 500, "Deer Description")
pdf_canvas.drawString(600, 500, "Observations")

# Looping to write dataframe rows in the PDF
for index, row in df.iterrows():
    pdf_canvas.drawRightString(10, 450, str(index+1))
    pdf_canvas.drawRightString(100, 450, row['date_time'].strftime("%Y-%m-%d %H:%M:%S"))
    pdf_canvas.drawRightString(200, 450, row['observation_location'])
    pdf_canvas.drawRightString(300, 450, row['environment_description'])
    pdf_canvas.drawRightString(400, 450, row['weather_description'])
    pdf_canvas.drawRightString(500, 450, row['white_tailed_deer_description'])
    pdf_canvas.drawRightString(600, 450, row['other_observations_description'])
    pdf_canvas.drawLine(10, 425, 700, 425)
    pdf_canvas.drawPage()

pdf_canvas.save()
pdf_canvas.close()
```

Note: Please replace `database_name` with your actual database name.

Sure, I can help you with that. Here's how you might create such a table in SQL:

```sql
CREATE TABLE WhiteTailedDeerObservations (
    ObservationID INT PRIMARY KEY AUTO_INCREMENT,
    ObservationDateTime DATETIME,
    ObservationLocation VARCHAR(255),
    EnvironmentDescription TEXT,
    DeerDescription TEXT,
    AdditionalNotes TEXT
);
```

This table includes an `ObservationID` column as a primary key, which will automatically increment with each new record. The other columns correspond to the information you specified.

To insert a new record into the table, you can use the following SQL command:

```sql
INSERT INTO WhiteTailedDeerObservations (ObservationDateTime, ObservationLocation, EnvironmentDescription, DeerDescription, AdditionalNotes)
VALUES ('2022-01-01 10:30:00', 'Forest near the lake', 'Sunny, warm, and calm', 'Medium-sized, calm, with a noticeable scar on the right flank', 'Observed eating leaves');
```

You would replace the values in the parentheses with the actual data for your new record.

To retrieve all observations from the table, you can use the following SQL command:

```sql
SELECT * FROM WhiteTailedDeerObservations;
```

As for exporting the retrieved observations as a PDF file, SQL itself does not have this capability. However, you can export the data to a CSV file using a command like this (in MySQL):

```sql
SELECT * FROM WhiteTailedDeerObservations
INTO OUTFILE '/tmp/observations.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n';
```

Then, you can use a variety of tools or programming languages (like Python with libraries such as pandas and matplotlib, or R with its PDF output functions) to convert the CSV file to a PDF.
