Method Detail

alterTable   [line 332]

mixed alterTable( string $name, array $changes, boolean $check)

alter an existing table
  • Return: MDB2_OK on success, a MDB2 error on failure
  • Access: public

Overridden in child classes as:

MDB2_Driver_Manager_xxx::alterTable()
alter an existing table

Parameters:

string   $name     name of the table that is intended to be changed.
array   $changes     

associative array that contains the details of each type of change that is intended to be performed. The types of changes that are currently supported are defined as follows:

name

New name for the table.

add

Associative array with the names of fields to be added as indexes of the array. The value of each entry of the array should be set to another associative array with the properties of the fields to be added. The properties of the fields should be the same as defined by the Metabase parser.

remove

Associative array with the names of fields to be removed as indexes of the array. Currently the values assigned to each entry are ignored. An empty array should be used for future compatibility.

rename

Associative array with the names of fields to be renamed as indexes of the array. The value of each entry of the array should be set to another associative array with the entry named name with the new field name and the entry named Declaration that is expected to contain the portion of the field declaration already in DBMS specific SQL code as it is used in the CREATE TABLE statement.

change

Associative array with the names of the fields to be changed as indexes of the array. Keep in mind that if it is intended to change either the name of a field and any other properties, the change array entries should have the new names of the fields as array indexes.

The value of each entry of the array should be set to another associative array with the properties of the fields to that are meant to be changed as array entries. These entries should be assigned to the new values of the respective properties. The properties of the fields should be the same as defined by the Metabase parser.

Example array( 'name' => 'userlist', 'add' => array( 'quota' => array( 'type' => 'integer', 'unsigned' => 1 ) ), 'remove' => array( 'file_limit' => array(), 'time_limit' => array() ), 'change' => array( 'gender' => array( 'default' => 'M', ) ), 'rename' => array( 'sex' => array( 'name' => 'gender', ) ) )

boolean   $check     indicates whether the function should just check if the DBMS driver can perform the requested table alterations if the value is true or actually perform them otherwise.

createDatabase   [line 141]

mixed createDatabase( mixed $database, string $name)

create a new database
  • Return: MDB2_OK on success, a MDB2 error on failure
  • Access: public

Overridden in child classes as:

MDB2_Driver_Manager_xxx::createDatabase()
create a new database

Parameters:

string   $name     name of the database that should be created

createIndex   [line 499]

mixed createIndex( string $table, string $name, array $definition)

get the stucture of a field into an array
  • Return: MDB2_OK on success, a MDB2 error on failure
  • Access: public

Overridden in child classes as:

MDB2_Driver_Manager_xxx::createIndex()
get the stucture of a field into an array

Parameters:

string   $table     name of the table on which the index is to be created
string   $name     name of the index to be created
array   $definition     

associative array that defines properties of the index to be created. Currently, only one property named FIELDS is supported. This property is also an associative with the names of the index fields as array indexes. Each entry of this array is set to another type of associative array that specifies properties of the index that are specific to each field.

Currently, only the sorting property is supported. It should be used to define the sorting direction of the index. It may be set to either ascending or descending.

Not all DBMS support index sorting direction configuration. The DBMS drivers of those that do not support it ignore this property. Use the function supports() to determine whether the DBMS driver can manage indexes.

Example array( 'fields' => array( 'user_name' => array( 'sorting' => 'ascending' ), 'last_login' => array() ) )

createSequence   [line 563]

mixed createSequence( string $seq_name, [string $start = 1])

create sequence
  • Return: MDB2_OK on success, a MDB2 error on failure
  • Access: public

Overridden in child classes as:

MDB2_Driver_Manager_xxx::createSequence()
create sequence

Parameters:

string   $seq_name     name of the sequence to be created
string   $start     start value of the sequence; default is 1

createTable   [line 206]

mixed createTable( string $name, array $fields)

create a new table
  • Return: MDB2_OK on success, a MDB2 error on failure
  • Access: public

Overridden in child classes as:

MDB2_Driver_Manager_xxx::createTable()
create a new table

Parameters:

string   $name     Name of the database that should be created
array   $fields     

Associative array that contains the definition of each field of the new table The indexes of the array entries are the names of the fields of the table an the array entry values are associative arrays like those that are meant to be passed with the field definitions to get[Type]Declaration() functions.

Example array(

'id' => array( 'type' => 'integer', 'unsigned' => 1 'notnull' => 1 'default' => 0 ), 'name' => array( 'type' => 'text', 'length' => 12 ), 'password' => array( 'type' => 'text', 'length' => 12 ) );
