Subject: [PATCH] Implement native boolean check constraint flag in test suite
|
|
|
896b32f |
|
|
|
896b32f |
This is based on
|
|
|
896b32f |
https://github.com/zzzeek/sqlalchemy/commit/d2bacad469c0b07cc707b563e37e835abcf96eb8
|
|
|
896b32f |
which adds further specificity to SQL Server's boolean behaviors,
|
|
|
896b32f |
the test suite here expects a CHECK constraint to be rendered.
