how can i get the int value using the sql language? like this,
"select cost from my_money_table " , the data type of cost is float.
take a look at
http://www.postgresql.org/docs/8.2/static/sql-expressions.html
CAST ( expression AS type )
expression::type
Incidentally, float is about the worst data type to represent monetary amounts
that one can choose.
