hi experts,

I am writing a search engine for my database. i am using MySQL, and using Perl dbi.
how can i write SQL statement so that it will check each field for the string?

i only know to check only one field like:
select * from table_name where name=$search_string

but i want to check not only the name field, but all the fields in that table.
thanks.

well if the data is all in the same table
you need to append to your where clause.

like so...

select * from table_name where name=$search_string || field_name2=$search_string || field_name3=$search_string etc...

if the data is across multible tables
you must prefix the table name using dot notation to the field name

select * from table_name where name=$search_string || table_name.field_name2=$search_string || table_name.field_name3=$search_string etc...


You could keep this information ( the table and field names ) in arrays for eassier management and execution of the querries.
