Hello
I'm looking for something like
if not exists( select 1 from PERSON where NAME = 'Test' ) then
insert into PERSON ( NAME ) values ( 'Test');
end if;
I did it with Sybase Database.
I need to get Data from Excel and have to be shure that there is no
data more than once in the table.
So I have to generate a script with test, if this data is in teh
table yet, or not, before inserting.
Maybe you could just use INSERT IGNORE ... SELECT FROM ... ?
That inserts records from one table into another table, ignoring
records that duplicate any existing unique key values.
Did You Understand? Sorry for my English
