How to find Mister/Miss right

So many fishes in the sea, but I can not see the right one.

Maybe it helps

In SQL Server

SELECT TOP 1 * FROM GIRLS WHERE SHE IS MY LOVE

In DB2

SELECT * FROM GIRLS WHERE SHE IS MY LOVE FETCH FIRST 1 ROWS ONLY

In MySQL

SELECT * FROM GIRLS WHERE SHE IS MY LOVE LIMIT 1

At the beginning, the query keeps simple. But sometimes, it is not easy.

like:

SELECT * FROM GIRLS WHERE SHE IS MY LOVE AND SHE CAN COOK AND SHE IS BEAUTIFUL AND BALABALA

What's more,

SELECT G,F,S,BEST(ONE) FROM GIRLS WHERE SHE IS MY LOVE AND SHE CAN COOK AND SHE IS BEAUTIFUL AND BALABALAGROUP BY G,F,S

What's more.

SELECT G,F,S,BEST(ONE) FROM BOYS WHERE HE IS MY LOVE AND HE CAN COOK AND HE IS HANDSOME AND BALABALAGROUP BY G,F,S HAVING SUM(balance)>10000... AND COUNT(PROPERTY)>1 AND COUNT(CAR)>1 AND BABABALA

As we know, In a millionaire level table,If there are too many conditions clause, it will affect the performance of the query. The search engine always takes a long time to get what you want.

Now we know why there are still so many fishes in the sea.

For love, keep it simple.
