Question

我基于一些coldfusion逻辑生成下面的sql语句，但它是错误的，我似乎无法找到原因，我尝试对它做了许多不同的修改，似乎没有任何帮助。

UPDATE MAIN_RECORDS 
SET JONUM = NULL, 
SET CUSTNAME = 'Super Sweet Name', 
SET CONTACTDT = 02/28/2011, 
SET ENGRECDT = 03/07/2011, 
SET HOW_WR_DT = 03/07/2011, 
SET COMM_DT = 03/29/2011, 
SET FACAVALDT = NULL, 
SET FAX_SUPDT = 03/07/2011, 
SET LINENUM = 'CLPRO L6', 
SET POLENUM = 'CLPRO 125 T T3', 
SET REASON = '03/07/11 NO VAC FAC THIS IS THE WRONG INFORMATION IT WAS ON HERE TWICE', 
SET REC_TYPE = 'H', 
SET ORDER_TYPE = 'P', 
SET CANCEL_ORDER = 'Y', 
SET State_abbr = 'IL', 
SET dbfk_state = 17, 
SET xx_streetnumber = '2626', 
SET xx_street = 'Fake St', 
SET xx_city = 'NEWTON', 
SET xx_class_of_service_ind = 'R', 
SET xx_cellphone_ind = '1', 
SET xx_assigned_phone = '3045653897', 
SET xx_exchange_name = 'NEWTON', 
SET XX_new_ref_code = '60', 
SET xx_new_service_type = '11', 
SET ORD_COMDT = 03/11/2011, 
SET delivery_date = NULL 
WHERE ordernum = '08824112' AND exchnum = '304565'

目前管理工作室给我的错误是：

Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'SET'.

Answer 1

您只需要1 SET个陈述，而不是您拥有的多个陈述。

此外，您的日期需要在它们周围加上单引号。

e.g：

UPDATE MAIN_RECORDS 
SET JONUM = NULL, 
    CUSTNAME = 'Super Sweet Name', 
    CONTACTDT = '02/28/2011', 
    ENGRECDT = '03/07/2011', 
    HOW_WR_DT = '03/07/2011', .....

Answer 2

查看UPDATE声明。帖子中的语法都错了：）

相关部分：

SET
        { column_name = { expression | DEFAULT | NULL }
        | @variable = expression
        | @variable = column = expression } [ ,...n ]

请注意，SET只能指定一次。 ,...n表示之前的使用（在{}中）可以指定附加 n次，用逗号分隔：SET关键字本身，但是，在那个结构之外。

快乐的编码。

Answer 3

通常，此命令语法将遵循此逻辑

UPDATE table_name
 SET column1=value, column2=value2,...
 WHERE some_column=some_value

所以只有一个SET不是您拥有的倍数

Answer 4

更新关键字中只需要一个SET来更新n个列 - 例如：

Update Employee 
set City = Chennai,Country ='India',Employee name = 'Vignesh'
where  Employee Id = 1X234

SQL Update语句 - “SET”附近的语法错误？
