Hi,
Testing expressions test app, the query generated into
BasicExpressionsTests.test_annotate_values_filter method:
companies = Company.objects.annotate(
foo=RawSQL('%s', ['value']),
).filter(foo='value').order_by('name')
Generate:
'SELECT "EXPRESSIONS_COMPANY"."ID", "EXPRESSIONS_COMPANY"."NAME",
"EXPRESSIONS_COMPANY"."NUM_EMPLOYEES", "EXPRESSIONS_COMPANY"."NUM_CHAIRS",
"EXPRESSIONS_COMPANY"."CEO_ID",
"EXPRESSIONS_COMPANY"."POINT_OF_CONTACT_ID", ? AS "FOO" FROM
"EXPRESSIONS_COMPANY" WHERE ? = ? ORDER BY "EXPRESSIONS_COMPANY"."NAME" ASC'
This sql command has 3 params (?), two of which are out of where clause.
? AS "FOO"
WHERE ? = ?
So, the underlying database driver execute this, doing something like this
cursor.execute(sql, ['value', 'value', 'value'])
Is correct that the 3 params are replaced into the entire sql and not just
on where clause ?
It depend of the implementation on each database driver?
Best regards
Maxi
