__construct(): Constructor.
__destruct(): Default destructor; does nothing other than provide a safe fallback for calls to parent::__destruct().
addColumn(): Adds a portable column to a table in the database.
apiVersion(): Reports the API version for this class.
begin(): Leave autocommit mode and begin a transaction.
commit(): Commit a transaction and return to autocommit mode.
connect(): Creates a PDO object and connects to the database.
createIndex(): Creates a portable index on a table.
createSequence(): Creates a sequence in the database.
createTable(): Creates a portable table.
delete(): Deletes rows from the table based on a WHERE clause.
disconnect(): Closes the database connection.
dropColumn(): Drops a column from a table in the database.
dropIndex(): Drops an index from a table in the database.
dropSequence(): Drops a sequence from the database.
dropTable(): Drops a table from the database, if it exists.
dump(): Convenience method for getting a dump the whole object, or one of its properties, or an external variable.
fetchAll(): Fetches all rows from the database using sequential keys.
fetchAssoc(): Fetches all rows from the database using associative keys (defined by the first column).
fetchCol(): Fetches the first column of all rows as a sequential array.
fetchOne(): Fetches one row from the database.
fetchPairs(): Fetches an associative array of all rows as key-value pairs (first column is the key, second column is the value).
fetchPdo(): Fetches a PDOStatement result object.
fetchSql(): Builds the SQL statement and returns it as a string instead of executing it.
fetchTableCols(): Returns an array describing table columns from the cache; if the cache entry is not available, queries the database for the column descriptions.
fetchTableList(): Returns a list of database tables from the cache; if the cache entry is not available, queries the database for the list of tables.
fetchValue(): Fetches the very first value (i.e., first column of the first row).
getCache(): Returns the cache object.
getCacheKeyPrefix(): Gets the connection-specific cache key prefix.
getPdo(): Get the PDO connection object (connects to the database if needed).
getProfile(): Get the query profile array.
insert(): Inserts a row of data into a table.
lastInsertId(): Get the last auto-incremented insert ID from the database.
locale(): Looks up class-specific locale strings based on a key.
nextSequence(): Gets the next number in a sequence; creates the sequence if it does not exist.
query(): Prepares and executes an SQL statement, optionally binding values to named parameters in the statement.
quote(): Safely quotes a value for an SQL statement.
quoteInto(): Quotes a value and places into a piece of text at a placeholder.
quoteMulti(): Quote multiple text-and-value pieces.
quoteName(): Quotes a single identifier name (table, table alias, table column, index, sequence).
quoteNamesIn(): Quotes all fully-qualified identifier names ("table.col") in a string, typically an SQL snippet for a SELECT clause.
rollback(): Roll back a transaction and return to autocommit mode.
setCache(): Injects a cache dependency for $_cache.
setCacheKeyPrefix(): Sets the connection-specific cache key prefix.
setProfiling(): Turns profiling on and off.
update(): Updates a table with specified data based on a WHERE clause.

_addProfile(): Adds an element to the profile array.
_bind(): Binds data as values into a prepared PDOStatment.

_createSequence(): Creates a sequence, optionally starting at a certain number.
_dropIndex(): Drops an index.
_dropSequence(): Drops a sequence.
_exception(): Convenience method for returning exceptions with localized text.
_fetchTableCols(): Describes the columns in a table.
_fetchTableList(): Returns a list of all tables in the database.
_getCacheKey(): Gets a full cache key.
_getDefault(): Given a native column SQL default value, finds a PHP literal value.
_getTypeSizeScope(): Given a column specification, parse into datatype, size, and decimal scope.
_modAutoincPrimary(): Given a column definition, modifies the auto-increment and primary-key clauses in place.
_modIndexName(): Modifies the index name.
_modSelect(): Modifies a SELECT statement in place to add a LIMIT clause.
_modSequenceName(): Modifies the sequence name.
_nextSequence(): Gets a sequence number; creates the sequence if it does not exist.
_postConnect(): After connection, set various connection attributes.
_prepare(): Prepares an SQL query as a PDOStatement object.
_quoteName(): Quotes an identifier name (table, index, etc).
_quoteNamesIn(): Quotes all fully-qualified identifier names ("table.col") in a string.
_select(): Returns a SELECT statement built from its component parts.
_setDsn(): Sets the DSN value for the connection from the config info.
_setup(): Follow-on setup from the constructor; useful for extended classes.
_sqlColdef(): Returns a column definition string.
_sqlCreateTable(): Returns a CREATE TABLE command string for the adapter.
