Overwrite/Join MySQL table with another table on select?

I think this aught to cover all your scenarios: SELECT COALESCE(b. Nullablefield, a. Nullablefield) as nullablefield, IF(b.

Intfield = 0, a. Intfield, b. Intfield) as intfield, IF(b.

Floatfield = 0, a. Floatfield, b. Floatfield) as floatfield, ... etc ... FROM table_a a LEFT JOIN table_b be ON a.

UniqueID = b.UniqueID.

SELECT UniqueID, COALESCE(b. Price1, a. Price1) as Price1, FROM productdata a LEFT JOIN product_overrides be ON a.

UniqueID = b. UniqueID WHERE UniqueID = "5676544"; gets me a 1064 syntax. If I swap * for COALESCE it works.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
