Mssqlex v0.5.1 Mssqlex.ODBC
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.
Summary
Functions
Commits a transaction on the ODBC driver
Disconnects from the ODBC driver
Sends a parametrized query to the ODBC driver
Rolls back a transaction on the ODBC driver
Starts the connection process to the ODBC driver
Functions
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, iodata, 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
is the :odbc
process id
statement
is the SQL query string
opts
are options to be passed on to :odbc
Rolls back a transaction on the ODBC driver.
pid
is the :odbc
process id
Starts the connection process to the ODBC driver.
conn_str
should be a connection string in the format required by
your ODBC driver.
opts
will be passed verbatim to :odbc.connect/2
