sql - How to combine IN operator with LIKE condition (or best way to get comparable results) -

-

I have to select the rows where a field starts with one of several different prefixes: 

 Select  from the table * where fields such as 'ab%' or fields like 'cd%' or "ef%" ... ...

using SQL What's the best way to do Oracle or SQL Server? I'm looking for something like the following statement (which is wrong): 

  Select * from the table where in the field ('ab%', 'cd%', 'ef%',). ..)

or 

  select from the table where in the field (choose foo from the bar)

edited Do: I want to see how it is done with giving all the prefixes in one helpful statement and giving it to all prefixes.

The length of the prefixes is not fixed.

By joining your prefix table with your actual table, both SQL Server & amp; Oracle Announcement @ Table tab (Field VARCHAR (32)) DECLARE @ Prefix Tables (prefix VARCHAR (32)) Insert into the eligible values ​​('ABC') INSERT @Table Enter VALUES ('def') Enabled values ​​('ADEF') @ Valid values ​​('DEFAB'). Insert @free values ​​('EFABD') @Prinfix values ​​('AB%') INSERT INSERT Choose from prefix value ('de%'). PF like @Profix PF on T. Field from @TableTInner Prefix

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'
