我的查询有什么问题

Question

以下是我的查询:

CREATE TABLE report_invoice(
'ID' INT(10) NOT NULL AUTO_INCREMENT,
'Invoice_No' VARCHAR(30) NOT NULL,
'Invoice_Type' INT(10) NOT NULL,
'Operator' VARCHAR(50) NOT NULL,
'Customer' VARCHAR(50) NOT NULL,
'Invoice_Date' DATE NOT NULL,
'Total' DECIMAL('10,2'),
PRIMARY KEY ('ID'));

我一直收到这个错误:

ERROR 1064 (42000): 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 ''ID'
INT(10) NOT NULL AUTO_INCREMENT,
'Invoice_No' VARCHAR(30) NOT NULL,
'Invoic' at line 2  

Answer 1

您在字段名称周围使用单引号,而是使用反引号:

CREATE TABLE report_invoice(
`ID` INT(10) NOT NULL AUTO_INCREMENT,
`Invoice_No` VARCHAR(30) NOT NULL,
`Invoice_Type` INT(10) NOT NULL,
`Operator` VARCHAR(50) NOT NULL,
`Customer` VARCHAR(50) NOT NULL,
`Invoice_Date` DATE NOT NULL,
`Total` DECIMAL(10,2),
PRIMARY KEY (`ID`));
