Instance Method Summary collapse
-
#connect(server) ⇒ Object
Create an instance of swift_class for the given options.
-
#execute(sql, opts = {}) ⇒ Object
Execute the given SQL, yielding a Swift::Result if a block is given.
-
#execute_dui(sql, opts = {}) ⇒ Object
Execute the SQL on the this database, returning the number of affected rows.
-
#execute_insert(sql, opts = {}) ⇒ Object
Execute the SQL on this database, returning the primary key of the table being inserted to.
-
#initialize(opts) ⇒ Database
constructor
Call the DATABASE_SETUP proc directly after initialization, so the object always uses sub adapter specific code.

Constructor Details
#initialize(opts) ⇒ Database
Call the DATABASE_SETUP proc directly after initialization, so the object always uses sub adapter specific code. Also, raise an error immediately if the connection doesn’t have a db_type specified, since one is required to include the correct subadapter.
