_dsn | ( | ) | [protected] |
Creates a PDO DSN for the adapter from $this->_config settings.
Reimplemented from Zend_Db_Adapter_Pdo_Abstract.
_quote | ( | $ | value ) | [protected] |
Quote a raw string. Most PDO drivers have an implementation for the quote() method, but the Oracle OCI driver must use the same implementation as the Zend_Db_Adapter_Abstract class.
string | $value | Raw string |
Reimplemented from Zend_Db_Adapter_Pdo_Abstract.
describeTable | ( | $ | tableName, |
$ | schemaName = null |
||
) |
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 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
string | $tableName | |
string | $schemaName | OPTIONAL |
Use FETCH_NUM so we are not dependent on the CASE attribute of the PDO connection
Oracle does not support auto-increment keys.
Reimplemented from Zend_Db_Adapter_Abstract.
lastInsertId | ( | $ | tableName = null , |
$ | primaryKey = null |
||
) |
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.
Oracle does not support IDENTITY columns, so if the sequence is not specified, this method returns null.
string | $tableName | OPTIONAL Name of table. |
string | $primaryKey | OPTIONAL Name of primary key column. |
Zend_Db_Adapter_Oracle_Exception |
Reimplemented from Zend_Db_Adapter_Pdo_Abstract.
lastSequenceId | ( | $ | sequenceName ) |
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.
string | $sequenceName |
Reimplemented from Zend_Db_Adapter_Abstract.
limit | ( | $ | sql, |
$ | count, | ||
$ | offset = 0 |
||
) |
Adds an adapter-specific LIMIT clause to the SELECT statement.
string | $sql | |
integer | $count | |
integer | $offset |
Zend_Db_Adapter_Exception |
Oracle does not implement the LIMIT clause as some RDBMS do. We have to simulate it with subqueries and ROWNUM. Unfortunately because we use the column wildcard "*", this puts an extra column into the query result set.
Reimplemented from Zend_Db_Adapter_Abstract.
listTables | ( | ) |
Returns a list of the tables in the database.
Reimplemented from Zend_Db_Adapter_Abstract.
nextSequenceId | ( | $ | sequenceName ) |
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.
string | $sequenceName |
Reimplemented from Zend_Db_Adapter_Abstract.
quoteTableAs | ( | $ | ident, |
$ | alias = null , |
||
$ | auto = false |
||
) |
Quote a table identifier and alias.
string | array | Zend_Db_Expr | $ident | The identifier or expression. |
string | $alias | An alias for the table. |
Reimplemented from Zend_Db_Adapter_Abstract.
