How Can I Debug and View Django's SQL Queries?
Troubleshooting Django SQL query issues
Debugging database interactions in Django can be challenging. Fortunately, there are ways to see the raw SQL queries that Django is executing.
Access SQL query
To access the executing SQL query, you can leverage Django’s connection object:
<code>from django.db import connection print(connection.queries)</code>
This will display a list of executed queries. Note that due to Django's parameterization, these queries may not be valid SQL.
Another way is to access the query attribute of the queryset:
<code>print(MyModel.objects.filter(name="my name").query)</code>
Reset query
If you need to reset the query list, for example to track the number of queries executed during a specific time period, you can use the reset_queries helper function:
<code>from django.db import reset_queries from django.db import connection reset_queries() # 在此处运行您的查询 print(connection.queries) # 将返回一个空列表</code>
By leveraging these techniques, you can understand the SQL queries executed by Django and troubleshoot issues that may arise in database interactions.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
