Detailed Description

AirDBC driver internals.

May be directly accessed by AirDBC drivers. Contains a set of function pointers that define the driver's actions.

Field Documentation

AdbConnectionFn _AdbDriver::alloc

Driver private allocation function.

Called by adb_conn_create() to allow driver to set up driver private information for the connection.

AdbConnectionFn _AdbDriver::close

Driver connection open function.

Called by adb_conn_close() to close the connection to the backend.

AdbFetchFn _AdbDriver::fetch

Driver result set fetch function.

May return pointers to driver private information; the AirDBC API specifies that applications should copy data returned from fetch if it must be accessed beyond a call to adb_rs_next().

AdbConnectionFreeFn _AdbDriver::free

Driver private disposal function.

Called by adb_conn_free() to free driver private information.

AdbResultSetFreeFn _AdbDriver::free_rs

Driver private result set disposal function.

Called by adb_rs_free() to free driver private result set information.

AdbStatementFreeFn _AdbDriver::free_stmt

Driver private statement disposal function.

Called by adb_stmt_free() to free driver private statement information.

const char* _AdbDriver::name

Driver name.

Corresponds to the URI scheme which will select this driver.

AdbResultSetFn _AdbDriver::next

Driver result set advance function.

Your driver must be set up to require adb_rs_next() to be called before first fetch (i.e., a next call before a fetch should not skip the first row.

AdbConnectionFn _AdbDriver::open

Driver connection open function.

Called by adb_conn_open() to open the connection to the backend.

const char* _AdbDriver::param_prefix

Native SQL parameter prefix string.

Each named prefix in the expression passed to adb_stmt_prepare() will be replaced with a string beginning with this substring.

AdbStatementFn _AdbDriver::prepare

Driver statement prepare function.

Called by adb_stmt_prepare() to allow driver to prepare native statement and set up driver private statement information for the statement.

AdbQueryFn _AdbDriver::query

Driver statement query function.

Called by adb_stmt_query() with a pre-allocated AdbResultSet to allow the driver to execute the query and set up driver private result set information.
