anyone know how can i do counting if in SQL alchemy like
COUN(IF(table_row = 1 AND table_row2 =2),1,0)
i make something like this,
func.COUNT(func.IF((TransactionMessage.tm_read==0 and TransactionMessage.tm_type==1),1,0)).label('t_message_count'),
But sqlalchemy make 2 seperate if with TransactionMesssage.tm_read, and TransactinMessage.tm_type
Could somone help me to resolve problem?
I do not have environment to test, but most probably you need to use sqlalchemy.sql.expression.and_ expression:
from sqlalchemy.sql.expression import and_
...
func.COUNT(func.IF(and_(TransactionMessage.tm_read == 0,
TransactionMessage.tm_type == 1), 1, 0)
).label('t_message_count'),
