cursor update + insert

hello guys,

I have a question, I have two tables with exactly the same settings example:


table1
NAME, AGE, DATE, IDENTIFIER, PHONE

table2
NAME, AGE, DATE, IDENTIFIER, PHONE

Table 1 is updated every day and I need to mount a cursor to read the record and compare to table2 record if they match make an update in table2 with data from table1.

if you have data in table1 in table2 that do not have an insert in table2 as I assemble this structure?

Try to use this

insert into table2
select NAME, AGE, DATE, IDENTIFIER, PHONE
FROM   table1
WHERE  NOT EXISTS
  (SELECT NAME, AGE, DATE, IDENTIFIER, PHONE
   FROM   table2
   WHERE  table2.NAME = table1.Name
and table2.Age = table1.age

and table2.date = table1.date
and table2.IDENTIFIER = table1.IDENTIFIER
and table2.PHONE = table1.Phone)

Hi,

Do you really need that cursor. I think you could easily solve the problem using this sintax:

insert into t1(a, b, c)
    select d, e, f from t2
    on duplicate key update b = e, c = f;

This, of course, assuming that there are unique keys in the tables.
