Linking Several Fields As One

[friend_al_23]

table1
id field1 field2 field3

table2
id field1 field2 field3

table3
id field1 field2 field3

Entries inside field1 of all the tables are the same. Can I link all field1 as one so that when I add, edit, and delete things in field1, it will also be done in all the other tables? and also to minimize the size of the database.

for ($i=1; $1 <= "3"; $i++)
{
//update query for table".$i."
}

I mean, to have only a single field for each of the three tables. Something like a relational database. To minimize SQL queries and amount of space.
