Question

I have a MySQL table that will only have one row. What should my statement be for the first time I insert to this row, and for subsequent updates? I tried an insert where the primary key equals 1, but this doesn’t account for the first time around when no row exists yet.

Answer 1

INSERT INTO table(col1,col2,col3) VALUES(val1,val2,val3) ON DUPLICATE KEY UPDATE col1 = val1, col2 = val2, col3 = val3;
