Methods

describeTable (line 149)

Returns the column descriptions for a table.

The return value is an associative array keyed by the column name, as returned by the RDBMS.

The value of each array element is an associative array with the following keys:

SCHEMA_NAME => string; name of database or schema TABLE_NAME => string; COLUMN_NAME => string; column name COLUMN_POSITION => number; ordinal position of column in table DATA_TYPE => string; SQL datatype name of column DEFAULT => string; default expression of column, null if none NULLABLE => boolean; true if column can have nulls LENGTH => number; length of CHAR/VARCHAR SCALE => number; scale of NUMERIC/DECIMAL PRECISION => number; precision of NUMERIC/DECIMAL UNSIGNED => boolean; unsigned property of an integer type PRIMARY => boolean; true if column is part of the primary key PRIMARY_POSITION => integer; position of column in primary key IDENTITY => integer; true if column is auto-generated with unique values

todo: Discover integer unsigned property.
access: public

array describeTable (string $tableName, [string $schemaName = null])

string $tableName
string $schemaName: OPTIONAL

Redefinition of:

Zend_Db_Adapter_Abstract::describeTable(): Returns the column descriptions for a table.

lastInsertId (line 317)

Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column.

As a convention, on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2), this method forms the name of a sequence from the arguments and returns the last id generated by that sequence. On RDBMS brands that support IDENTITY/AUTOINCREMENT columns, this method returns the last value generated for such a column, and the table name argument is disregarded.

access: public

string lastInsertId ([string $tableName = null], [string $primaryKey = null])

string $tableName: OPTIONAL Name of table.
string $primaryKey: OPTIONAL Name of primary key column.

Redefinition of:

Zend_Db_Adapter_Pdo_Abstract::lastInsertId(): Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column.

lastSequenceId (line 281)

Return the most recent value from the specified sequence in the database.

This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null.

access: public

string lastSequenceId (string $sequenceName)

string $sequenceName

Redefinition of:

Zend_Db_Adapter_Abstract::lastSequenceId(): Return the most recent value from the specified sequence in the database.

limit (line 245)

Adds an adapter-specific LIMIT clause to the SELECT statement.

access: public

string limit (string $sql, integer $count, [integer $offset = 0])

string $sql
integer $count
integer $offset: OPTIONAL

Redefinition of:

Zend_Db_Adapter_Abstract::limit(): Adds an adapter-specific LIMIT clause to the SELECT statement.

listTables (line 100)

Returns a list of the tables in the database.

access: public

array listTables ()

Redefinition of:

Zend_Db_Adapter_Abstract::listTables(): Returns a list of the tables in the database.

nextSequenceId (line 296)

Generate a new value from the specified sequence in the database, and return it.

This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null.

access: public

string nextSequenceId (string $sequenceName)

string $sequenceName

Redefinition of:

Zend_Db_Adapter_Abstract::nextSequenceId(): Generate a new value from the specified sequence in the database, and return it.

_connect (line 81)

Creates a PDO object and connects to the database.

throws: Zend_Db_Adapter_Exception
access: protected

void _connect ()

Redefinition of:

Zend_Db_Adapter_Pdo_Abstract::_connect(): Creates a PDO object and connects to the database.
