Hash Table Versus Switch Statement?
Sep 8, 2009I have about 100 strings that depend on an integer value. There is potential for the list to grow to 255. What is the faster/preferred method of assigning the string based on the passed integer, a hash table or a switch statement. I googled around and can't seem to find anything that compares the speed of the hash table lookup vs. the speed of the switch statement. Is there an easy way I could measure the speed myself or any links to articles describing the performace of each method?

This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.

Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
