Method Details
createCompositeInCondition()
method
|
protected string createCompositeInCondition(CDbTableSchema $table, array $values, string $prefix)
| ||
| $table | CDbTableSchema | the table schema |
| $values | array | list of primary key values to be selected within |
| $prefix | string | column prefix (ended with dot) |
| {return} | string | the expression for selection |
Source Code: framework/db/schema/sqlite/CSqliteCommandBuilder.php#30 (show)
protected function createCompositeInCondition($table,$values,$prefix)
{
$keyNames=array();
foreach(array_keys($values[0]) as $name)
$keyNames[]=$prefix.$table->columns[$name]->rawName;
$vs=array();
foreach($values as $value)
$vs[]=implode("||','||",$value);
return implode("||','||",$keyNames).' IN ('.implode(', ',$vs).')';
}
Generates the expression for selecting rows with specified composite key values. This method is overridden because SQLite does not support the default IN expression with composite columns.
