thanks but is not the way.
Think of a table with these 3 fields (tAB A)
name gender address
record 1: paul - m - john wayne street
record 25: peter - m - j.wayne st.
record 39: bill - m - st.j.wayne
AND tABLE B
record x, field address : j. wayne street (the right structure)
i have to create a new table in which record 1, table A, address field, become paul - m - "j. wayne street" (as written in table b);
record 25,table A, become : peter - m - "j. wayne street", etc.etc.
