Hello,
I'm sure I'll be flagged as a moron for asking this question, so be it.
I have some tables of info with no primary keys. As a result the field I want to key on is repeated. My plan is to do
aDISTINCT select from the un-keyed table into another table that does have constraints.
Here is what I thought would work:
INSERT INTO table2
SELECT DISTINCT(key), name, field1, field2
FROM table1;
When I issue this statement it tells me that you cannot put in duplicate values into my key field. Why does it do
that? If I issue the following statement I get exactly what I want:
SELECT DISTINCT(phone) from table1;
Am I using the DISTINCT function incorrectly? Is it taking all of the field and using them to create a distinct row?
Any help would be appreciated.
Chris.
