PostgreSQL 8.3 data types: xml vs varchar -

-

There is XML data type in postgres, I have never used it before, so I want to hear feedback. Dosacides and upsides using regular varchar (or text) columns to store XML

The text I will write is XML, well-formed, there is no need to search by UTF-8 (search by XML is slow).

This XML is actually ready for PDF PDFs with Apache FOP XML can be dynamically generated from the data found elsewhere (other postgres tables) , It is stored only so that I do not need to generate it twice . Kind Backup # 2 for pre-generated PDF documents.

To learn something else? Good practice, performance, maintenance, etc?

XML is different from TEXT only logical Firstly, the validity of the input is checked, second, XML is a type of compression operator, so you can call it UNION or DISTINCT < / Code> etc.

If you are not searching against it using indexes and want to create additional checks for validity, then use XML securely.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
