Method Summary
	`__init__(self, connectArgs, pool, verbose, initFunc)`
	`describeTable(self, table, schema, sequence_mapper)` for the given table, returns a 2-tuple: a dict of Field objects keyed by name, and list of multi-column unique constraints (sets of Fields)).
	`execute(self, sql, values, qualified)` Executes the statement with the values and does conversion of the return result as necessary.
	`field_values(row)` Produces the value of each item in the row, reading any LOBs before the LOB locators get invalidated by a subsequent fetch. (Static method)
	`getAutoIncrement(self, name)` If db uses auto increment, should obtain the value of the auto-incremented field named 'name'
	`listTables(self, schema)` lists the tables in the database schema
	`sequence_mapper(table, column)` (Static method)
Inherited from DBIBase
	`_connect(self)`
	`_convertResultSet(description, resultset, qualified)` internal function that turns a result set into a list of dictionaries. (Static method)
	`_initExceptions(self)`
	`commit(self)` commits a transaction
	`cursor(self)` returns a database cursor for direct access to the db connection
	`endConnection(self)` disassociate from the current connection, which may be deleted or returned to a pool.
	`getConverter(self)` returns a converter instance.
	`getSequence(self, name, field, table)` If db has sequences, this should return the next value of the sequence named 'name'
	`orderByString(order, limit, offset)` (Static method)
	`rollback(self)` rolls back a transaction
	`swapConnection(self, connection)` switch the connection in use for the current thread with another one.

Instance Method Details

describeTable(self, table, schema=None, sequence_mapper=None)

for the given table, returns a 2-tuple: a dict of Field objects keyed by name, and list of multi-column unique constraints (sets of Fields)). The Field instances should contain information about whether they are unique or sequenced.

Overrides:: pydo.dbi.DBIBase.describeTable

execute(self, sql, values=(), qualified=False)

Executes the statement with the values and does conversion of the return result as necessary. result is list of dictionaries, or number of rows affected

Overrides:: pydo.dbi.DBIBase.execute

getAutoIncrement(self, name)

If db uses auto increment, should obtain the value of the auto-incremented field named 'name'

Overrides:: pydo.dbi.DBIBase.getAutoIncrement

listTables(self, schema=None)

lists the tables in the database schema

Overrides:: pydo.dbi.DBIBase.listTables

Static Method Details

field_values(row)

Produces the value of each item in the row, reading any LOBs before the LOB locators get invalidated by a subsequent fetch.

Class Variable Details

auto_increment

Type:: bool
Value:: True

autocommit

Type:: NoneType
Value:: None

paramstyle

Type:: str
Value:: 'named'
