summary: In which I explain how to see SQL queries generated for DBIx::Class.
title: debug your DBIx::Class queries
---
If you use DBIx::Class and want to see what the SQL generated looks like, you can set the environment variable **DBIC_TRACE**.
```sh
% DBIC_TRACE=1 my_programme.pl
```
And all the SQL will be printed on **STDERR**.
If you give a filename to the variable, like this
```sh
% DBIC_TRACE="1=/tmp/sql.debug"
```
all the statements will be printed in this file.
