fix oci batchInsert
fix oci schema type errors
when oci creates ColumnSchema, it forgot to get column php type, and the implement of `extractColumnType` is incomplete, must add common used CLOB and BLOB type
Column name `child` must be quoted.
If the select value of column `data` is resource, use the contents of it.
fix phpTypecast bugs
if phpType is string and value type is resource, we must use `stream_get_contents` to cast value to string, instead of return the resource handle.
Ignore update parameter \yii\db\oci\QueryBuilder::addForeignKey()
Ingore update parameter instead of throw an exception. This can make consistency of all db in DDL.
