View Full Version : Searching a table technique

03-25-2009, 06:11 PM

I have an SQL database with a table that has about 20 columns and about 30 rows.

I need to perform a search on the whole table based on the values from one row: I need to find what other rows have similar values with the row that I base my search on. The similarities can vary from 1 column to all 20 columns.

I am not very experienced with SQL, I only know the some basic things and I need help in writing the code to perform the search (PHP).

Please help.

Thank you.

What exactly are you trying to search for, and how are you comparing?

You can pass in a value and use the LIKE (http://dev.mysql.com/doc/refman/5.0/en/string-comparison-functions.html) keyword to do your column comparisons for you.

FROM `my_table`
WHERE `column_1` LIKE '%bleh%'

-- % is a wildcard where SQL string comparisons go.
-- Anything can come in place of the '%'.

-- In the example, '%bleh%' could match results to:

-- * 'asfasfblehasdfasdf'
-- * 'my name is bleh'
