Hi, Because i don't like the mysql DELETE syntax, i prefer using this quick method:
% create a new table = table1 CREATE TABLE Table3 (...) % insert into table3 the records from table1 that aren't in table2 INSERT INTO Table3 (Table3.fields) SELECT Table1.fields FROM Table1 LEFT JOIN Table2 USING (id) WHERE Table2.id IS NULL % remove table1 DROP TABLE Table1 % rename table3 to table1 RENAME TABLE Table3 TO Table1; On Tue, 2002-01-15 at 22:32, SNK wrote: > Hi , I would need help with the syntax for this: > > I have Table1 and Table2.
