可以使用Python的MySQL驱动程序将二进制图片从MySQL数据库中检索出来,并在PyCharm中进行查看。以下是基本的代码示例:
```python
import mysql.connector
from mysql.connector import Error
import io
from PIL import Image
try:
connection = mysql.connector.connect(host='localhost',
database='database_name',
user='username',
password='password')
sql_fetch_blob_query = """SELECT image_column FROM table_name WHERE id = %s"""
cursor = connection.cursor()
cursor.execute(sql_fetch_blob_query, (1,))
record = cursor.fetchone()
image = record[0]
# 将二进制数据读入内存
image_data = io.BytesIO(image)
# 使用Pillow库打开内存中的图片
img = Image.open(image_data)
img.show()
except Error as e:
print("Error reading data from MySQL table", e)
finally:
if (connection.is_connected()):
cursor.close()
connection.close()
print("MySQL connection is closed")
```
请将 `database_name`、`username`、`password`、`image_column` 和 `table_name` 替换为您的实际值,并将 `id` 更改为要检索的特定图像的ID。这将从MySQL数据库中获取二进制图像数据,并使用Pillow库将其读入内存并在PyCharm中显示。
