|

|
|
* @param string $name name of the table that is intended to be changed.
|
|
* @param 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.
