Property Details
Character used to escape special characters in LIKE conditions.

with \
.

Method Details
Builds a SQL statement for adding a foreign key constraint to an existing table.
The method will properly quote the table and column names.
public string addForeignKey ( $name, $table, $columns, $refTable, $refColumns, $delete = null, $update = null ) | ||
$name | string | The name of the foreign key constraint. |
$table | string | The table that the foreign key constraint will be added to. |
$columns | string|array | The name of the column to that the constraint will be added on. If there are multiple columns, separate them with commas or use an array to represent them. |
$refTable | string | The table that the foreign key references to. |
$refColumns | string|array | The name of the column that the foreign key references to. If there are multiple columns, separate them with commas or use an array to represent them. |
$delete | string | The ON DELETE option. Most DBMS support these options: RESTRICT, CASCADE, NO ACTION, SET DEFAULT, SET NULL |
$update | string | The ON UPDATE option. Most DBMS support these options: RESTRICT, CASCADE, NO ACTION, SET DEFAULT, SET NULL |
return | string | The SQL statement for adding a foreign key constraint to an existing table. |
---|
Builds a SQL statement for changing the definition of a column.
public string alterColumn ( $table, $column, $type ) | ||

$column | string | The name of the column to be changed. The name will be properly quoted by the method. |
$type | string | The new column type. The getColumnType() method will be invoked to convert abstract column type (if any) into the physical one. Anything that is not recognized as abstract type will be kept in the generated SQL. For example, 'string' will be turned into 'varchar(255)', while 'string not null' will become 'varchar(255) not null'. |
return | string | The SQL statement for changing the definition of a column. |
---|

$params | array | The binding parameters to be populated |
return | string | The generated SQL expression |

return | string | The SELECT EXISTS() SQL statement. |
---|
Oracle DBMS does not support more than 1000 parameters in IN
