Help with SQL Statement Please

[tangosdad]

I've got two tables - members and sponsor, their simplified structure below.

members:
id_num
program_id
sponsor_program_id

sponsor:
id_num
sponsor

Some of the members in members table are sponsors. I need to update the field sponsor_program_id in all records in members table with their sponsors program_id field. Sponsor table tells me who their sponsor is, i.e. gives me their id_num back in members. So the contents of program_id of the sponsor goes into the sponsor_program_id of the person they sponsored.

I'm very new to this and I am lost! Can someone help?

update members set members.sponsor_program_id=sponser.program_id where sponser.id_num=members.id_num;

This will update the members by setting sponser_program_id to the program_id of sponser when id_num of sponser is equal to id_num of members.

Perhaps you could give an example to more clearly illustrate what you are trying to do?

Here is some simplified sample data, maybe this will help.

members:
id_num = 1
program_id = 123
sponsor_program_id = 92

extra:
id_num = 1
sponsor = 0

members:
id_num = 2
program_id = 545
sponsor_program_id =

extra:
id_num = 2
sponsor = 1

Ok, so here are two members. id_num 1 & 2. id_num 1 is id_num 2's sponsor based on record in extra table. I need an sql statement that will update id_num 2's sponsor_program_id with id_num 1's program_id of 123
