Db/Adapter/Abstract.php

$config is an array of key/value pairs or an instance of Zend_Config containing configuration options. These options are common to most adapters:

dbname => (string) The name of the database to user username => (string) Connect to the database as this username. password => (string) Password associated with the username. host => (string) What host to connect to, defaults to localhost

Some options are used on a case-by-case basis by adapters:

port => (string) The port of the database persistent => (boolean) Whether to use a persistent connection or not, defaults to false protocol => (string) The network protocol, defaults to TCPIP caseFolding => (int) style of case-alteration used for identifiers

Throw exceptions if any are missing.

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

Uses the current fetchMode for the adapter.

The first column is the key, the entire row array is the value. You should construct the query to be sure that the first column contains unique values, or else rows with duplicate values in the first column will overwrite previous data.

The first column in each row is used as the array key.

The first column is the key, the second column is the value.

This is not intended to be used by application code, but the method must be public so the Statement class can invoke it.

If not presently connected, this initiates the connection.

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.

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

If an array is passed as the value, the array values are quoted and then returned as a comma-separated string.

Accepts a string representing a qualified indentifier. For Example: $adapter->quoteIdentifier('myschema.mytable') Returns: "myschema"."mytable"

Or, an array of one or more identifiers that may form a qualified identifier: $adapter->quoteIdentifier(array('myschema','my.table')) Returns: "myschema"."my.table"

The actual quote character surrounding the identifiers may vary depending on the adapter.

The placeholder is a question-mark; all placeholders will be replaced with the quoted value. For example:

$text = "WHERE date < ?"; $date = "2005-01-02"; $safe = $sql->quoteInto($text, $date); // $safe = "WHERE date < '2005-01-02'"

The argument may be a boolean, an associative array, an instance of Zend_Db_Profiler, or an instance of Zend_Config.

A boolean argument sets the profiler to enabled if true, or disabled if false. The profiler class is the adapter's default profiler class, Zend_Db_Profiler.

An instance of Zend_Db_Profiler sets the adapter's instance to that object. The profiler is enabled and disabled separately.

An associative array argument may contain any of the keys 'enabled', 'class', and 'instance'. The 'enabled' and 'instance' keys correspond to the boolean and object types documented above. The 'class' key is used to name a class to use for a custom profiler. The class must be Zend_Db_Profiler or a subclass. The class is instantiated with no constructor arguments. The 'class' option is ignored when the 'instance' option is supplied.

An object of type Zend_Config may contain the properties 'enabled', 'class', and 'instance', just as if an associative array had been passed instead.
