18. Using SQL reserved names
|
||
|
|
|
||
|
|
Need to use a reserved SQL name as a column name or table name? Need to include
|
||
|
|
a hyphen in a column or table name? No problem. Django quotes names
|
||
|
|
appropriately behind the scenes, so your database won't complain about
|
||
|
|
reserved-name usage.
