Mssqlex v2.0.0-beta.0 Mssqlex.ODBC View Source
Adapter to Erlang's :odbc
module.
This module is a GenServer that handles communication between Elixir
and Erlang's :odbc
module. Transformations are kept to a minimum,
primarily just translating binaries to charlists and vice versa.
It is used by Mssqlex.Protocol
and should not generally be
accessed directly.

.
Commits a transaction on the ODBC driver.
Note that unless in autocommit mode, all queries are wrapped in implicit transactions and must be committed.
pid
is the :odbc
process id
Disconnects from the ODBC driver.
Attempts to roll back any pending transactions. If a pending transaction cannot be rolled back the disconnect still happens without any changes being committed.
pid
is the :odbc
process id
query(pid, statement, params, opts)
View Sourcequery(pid(), iodata(), Keyword.t(), Keyword.t()) :: {:selected, [binary()], [tuple()] | {:updated, non_neg_integer()}} | {:error, Exception.t()}
Sends a parametrized query to the ODBC driver.
Interface to :odbc.param_query/3
.See
Erlang's ODBC guide
for usage details and examples.
pid
