Overview

Class for Oracle (OCI) behaviors.

Many thanks to James Kilbride, Darwin Cruz, and others at General Dynamics for this BSD-Licensed contribution.

Special note: make sure the connecting user has permission to issue an ALTER SESSION SET NLS_DATE_FORMAT command; this makes the Oracle dates ISO compliant.

Package

This class is part of the Solar_Sql package.

Inheritance:

Solar_Base
- Solar_Sql_Adapter
  - Solar_Sql_Adapter_Oracle

Configuration Keys

host: Host specification (typically 'localhost').
port: Port number for the host name.
sock: The Unix socket for the connection. Should not be used with host and port.
user: Connect to the database as this username.
pass: Password associated with the username.
name: Database name (or file path, or TNS name).
profiling: Turn on query profiling?
cache: The cache to use, if any, for the lists of table names, table columns, etc.

Constants

None.

Public Methods

These are all the public methods in the Solar_Sql_Adapter_Oracle class.

You can also view the list of all public, protected, and private methods.

__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.
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(): Overrides the adapter's create Table to manage Oracle's specific needs for table creation.
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.
fetchIndexInfo(): Returns an array describing table indexes from the cache; if the cache entry is not available, queries the database for the index information.
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; the placeholder is a question-mark.
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.
