受保护方法

隐藏继承方法

方法描述定义在
createCompositeInCondition()生成根据指定符合键选择行的表达式。CSqliteCommandBuilder
ensureTable()Checks if the parameter is a valid table schema.CDbCommandBuilder

方法详细

createCompositeInCondition() 方法
protected string createCompositeInCondition(CDbTableSchema $table, array $values, string $prefix)
$tableCDbTableSchema表schema
$valuesarray要选择的主键值列表
$prefixstring列前缀(以.结束)
{return}string选择的表达式
源码: framework/db/schema/sqlite/CSqliteCommandBuilder.php#30 (显示) protectedfunctioncreateCompositeInCondition($table,$values,$prefix)
{
$keyNames=array();
foreach(array_keys($values[0])as$name)
$keyNames[]=$prefix.$table->columns[$name]->rawName;
$vs=array();
foreach($valuesas$value)
$vs[]=implode("||','||",$value);
returnimplode("||','||",$keyNames).'IN('.implode(',',$vs).')';
}

生成根据指定符合键选择行的表达式。 该方法被重写了,因为SQLite不支持 带有复合列的默认IN表达式。
