Qore::SQL Namespace Reference

Qore::SQL namespace. More...

## Classes
class | AbstractDatasource
| This class defines an abstract interface for database access, inherited by both the Datasource and DatasourcePool classes. More...
class | Datasource
| This class provides the Qore interface to databases. More...
class | DatasourcePool
| Provides transparent per-thread, per-transaction datasource connection pooling. More...
class | SQLStatement
| The SQLStatement class provides the most flexibilty for executing SQL on a database server. More...

## Functions
*int | getDBIDriverCapabilities (string driver)
| Returns an integer representing the capabilities of a DBI driver binary-OR'ed together (see DBI Capability Constants) or NOTHING if the driver is not already loaded. More...
nothing | getDBIDriverCapabilities ()
| This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments. More...
*list | getDBIDriverCapabilityList (string driver)
| Returns a list of each capability supported by the given DBI driver (see DBI Capability Constants) or NOTHING if the driver cannot be found. More...
nothing | getDBIDriverCapabilityList ()
| This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments. More...
*list | getDBIDriverList ()
| Returns a list of strings of DBI drivers currently loaded or NOTHING if no drivers are loaded. More...
hash | parseDatasource (string ds)
| Returns a datasource hash of the components of a datasource string. More...
nothing | parseDatasource ()
| This function variant does nothing at all; it is only included for backwards-compatibility with qore prior to version 0.8.0 for functions that would ignore type errors in arguments. More...
int | dbi_get_driver_capabilities (string driver)
| Returns an integer representing the capabilities of a DBI driver binary-OR'ed together (see DBI Capability Constants) or 0 if the driver is not already loaded. More...
*list | dbi_get_driver_capability_list (string driver)
| Returns a list of each capability supported by the given DBI driver (see DBI Capability Constants) or NOTHING if the driver cannot be found. More...
*list | dbi_get_driver_list ()
| Returns a list of strings of DBI drivers currently loaded or NOTHING if no drivers are loaded. More...
*hash | dbi_get_driver_options (string driver)
| returns a hash of driver options More...
hash | parse_datasource (string ds)
| Returns a datasource hash of the components of a datasource string. More...

## Variables
const | DSDB2 = "db2"
| for the `"db2"` driver
const | DSFreeTDS = "freetds"
| for the `"freetds"` driver
const | DSMSSQL = "freetds"
| another constant for the `"freetds"` driver
const | DSMySQL = "mysql"
| for the `"mysql"` driver
const | DSOracle = "oracle"
| for the `"oracle"` driver
const | DSPGSQL = "pgsql"
| for the `"pgsql"` driver
const | DSSQLite3 = "sqlite3"
| for the `"sqlite3"` driver
const | DSSybase = "sybase"
| for the `"sybase"` driver
const | DBI_CAP_AUTORECONNECT = DBI_CAP_AUTORECONNECT
| Indicates that the DBI driver supports automatically/transparently reconnecting to the server if the connection is lost while not in a transaction.
const | DBI_CAP_BIND_BY_PLACEHOLDER = DBI_CAP_BIND_BY_PLACEHOLDER
| Indicates that the DBI driver supports binding placeholder buffers when executing SQL to retrieve data from queries and procedures, etc.
const | DBI_CAP_BIND_BY_VALUE = DBI_CAP_BIND_BY_VALUE
| Indicates that the DBI driver supports directly binding qore values into queries using the `%v` placeholder in the query string.
const | DBI_CAP_CHARSET_SUPPORT = DBI_CAP_CHARSET_SUPPORT
| Indicates that the DBI driver supports proper character encoding conversions.
const | DBI_CAP_EVENTS = DBI_CAP_EVENTS
| Indicates that the DBI driver supports the event API.
const | DBI_CAP_HAS_DESCRIBE = DBI_CAP_HAS_DESCRIBE
| Indicates that the DBI driver supports the describe method.
const | DBI_CAP_HAS_EXECRAW = DBI_CAP_HAS_EXECRAW
| Indicates that the DBI driver supports the Datasource::execRaw() and DatasourcePool::execRaw() methods.
const | DBI_CAP_HAS_NUMBER_SUPPORT = DBI_CAP_HAS_NUMBER_SUPPORT
| Indicates that the DBI driver supports arbitrary-precision numeric support for binding and retrieving values.
const | DBI_CAP_HAS_OPTION_SUPPORT = DBI_CAP_HAS_OPTION_SUPPORT
| Indicates that the DBI driver supports the new driver option API.
const | DBI_CAP_HAS_SELECT_ROW = DBI_CAP_HAS_SELECT_ROW
| Indicates that the DBI driver supports a native selectRow() method implementation.
const | DBI_CAP_HAS_STATEMENT = DBI_CAP_HAS_STATEMENT

const | DBI_CAP_LOB_SUPPORT = DBI_CAP_LOB_SUPPORT
| Indicates that the DBI driver supports LOB columns (BLOBs and CLOBs, for example)
const | DBI_CAP_SERVER_TIME_ZONE = DBI_CAP_SERVER_TIME_ZONE
| Indicates that the DBI driver supports automatically converting date/time values to the server's presumed time zone (also implies that the driver supports the `"timezone"` option) and tagging date/time values with the same; this is independent from the client's current time zone setting.
const | DBI_CAP_STORED_PROCEDURES = DBI_CAP_STORED_PROCEDURES
| Indicates that the DBI driver supports stored procedure execution.
const | DBI_CAP_TIME_ZONE_SUPPORT = DBI_CAP_TIME_ZONE_SUPPORT
| Indicates that the DBI driver supports time zones in times.
const | DBI_CAP_TRANSACTION_MANAGEMENT = DBI_CAP_TRANSACTION_MANAGEMENT
| Indicates that the DBI driver supports transaction management.
const | BLOB = "blob"
| for binding BLOB values
