How Can I Obtain Compiled SQL from a SQLAlchemy Expression?

Obtain Compiled SQL from SQLAlchemy Expression

In SQLAlchemy, obtaining the raw, compiled SQL query from an expression can be elusive. However, there are ways to accomplish this:

One approach involves using the compile_kwargs argument. By setting "literal_binds" to True, you can print the query statement with included parameters:

print(q.statement.compile(compile_kwargs={"literal_binds": True}))

Note that this method has limitations, such as not supporting complex data types or bind parameters without predefined values.

Additionally, it's important to heed the warning mentioned in the documentation: Always use bound parameters when invoking non-DDL SQL statements from untrusted sources to prevent potential security risks.
