Question

I have a problem about inserting values into the table with sqlite.
supposing the table:

create table test 
{ 
    KeyName varchar(50) primary key,
    KeyValue varchar (255)

};

I want to insert data like ('john', 'friend'), but I don’t know whether the 'john' existed.
Currently I solve it:

1. using select * where KeyName = “john”
2. according the result from list 1, I use insert or update;

I’d like to know whether there is better solution?
thanks

Answer 1

you can use insert or replace which replaces the record if it already exists.

so you query be INSERT OR REPLACE INTO
