mysql左连接多个表

Question

I have a database which stores information about cars. There are 3 tables which don't have foreign keys:

make(make_ID, name,..)

colour(colour_ID,c_name,...)

engine(engine_ID,eng_size,...)

There's a 4th table which connects all the others together using foreign keys(FK):

carDetails(CarDetails_ID, CD_make_ID, CD_colorID,...)

Now I would like to use left joins to retrieve the appropriate information from tables about a car by using the IDs in the query.

Ideally I would like to select the make.name WHERE make.make_ID = carDetails.CD_make_ID etc. and keep joining extra information on the left. I have tried this and i'm getting errors on the 'where' clause...apparently it cannot be recognized.

SELECT name FROM make WHERE 'make.make_ID' = 'carDetails.CD_make_ID' LEFT JOIN colour.name WHERE colour.colour_ID = carDetails.CD_colour_ID

What am I doing wrong?

尝试这个

SELECT name FROM make, carDetails WHERE 'make.make_ID' = 'carDetails.CD_make_ID' LEFT JOIN colour.name ON colour.colour_ID = carDetails.CD_colour_ID
