SQL 语法错误。我的语法错误在哪里？

Question

我这辈子都不能发现我的错字！

UPDATE orders o, orders_total_couponz otc
    SET o.total_paid = o.total_paid - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    SET o.total_paid_tax_incl = o.total_paid_tax_incl - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    SET o.total_paid_tax_excl = o.total_paid_tax_excl - otc.converted_value,
    SET o.total_paid_tax_real = o.total_paid_tax_real - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    SET o.total_products = o.total_products - otc.converted_value,
    SET o.total_products_wt = o.total_products_wt - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) )
WHERE o.id_order = otc.orders_id

错误：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET o.total_paid_tax_incl = o.total_paid_tax_incl - ( otc.converted_value * ( 1 ' at line 3

Answer 1

仅使用一次 set 关键字，并以逗号分隔要设置的值：

UPDATE orders o, orders_total_couponz otc
SET o.total_paid = o.total_paid - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    o.total_paid_tax_incl = o.total_paid_tax_incl - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    o.total_paid_tax_excl = o.total_paid_tax_excl - otc.converted_value,
    o.total_paid_tax_real = o.total_paid_tax_real - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    o.total_products = o.total_products - otc.converted_value,
    o.total_products_wt = o.total_products_wt - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) )
WHERE o.id_order = otc.orders_id

Answer 2

不要反复使用SET。使用如下命令：

UPDATE orders o, orders_total_couponz otc
    SET o.total_paid = o.total_paid - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
     o.total_paid_tax_incl = o.total_paid_tax_incl - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    o.total_paid_tax_excl = o.total_paid_tax_excl - otc.converted_value,
    o.total_paid_tax_real = o.total_paid_tax_real - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) ),
    o.total_products = o.total_products - otc.converted_value,
    o.total_products_wt = o.total_products_wt - ( otc.converted_value * ( 1 + ( otc.tax_rate / 100 ) ) )
WHERE o.id_order = otc.orders_id
