how to check the existance of a record stored in a database

[Nadine Hossam]

hi all,
i have stored the cities' names in the database so that i can use these records in extracting cities from any given document.
what's the best way to do so?

1- The simplest way is to get each single record(city name) and check whether it exists in the document or not, but this will take a lot of time (looping through all the records, knowing that we have about 2000 city)

2- I thought of using regular expressions by placing all the cities in one regular expression like this (Anguilla|Vienna|Aberdeen|Boston|Egypt|Columbia....etc)
but as we said before it ll be too long regular expression that will take long time too

can anyone tell me what to do, what's the best solution in such cases
