在创建表格时,我收到错误#1089-错误的前缀密钥。
我的sql代码:
CREATE TABLE `buildblockz`.`db_user_info` ( `BBZUID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT 'User''s Id' , `username` VARCHAR(255) NOT NULL COMMENT 'User''s username' , `password` VARCHAR(255) NOT NULL COMMENT 'User''s password' , `fname` VARCHAR(255) NOT NULL COMMENT 'User''s First Name' , `mname` VARCHAR(255) NULL COMMENT 'User''s Middle Name' , `lname` VARCHAR(255) NOT NULL COMMENT 'User''s Last Name' , `line1` VARCHAR(255) NOT NULL COMMENT 'User''s Address Line 1' , `line2` VARCHAR(255) NULL COMMENT 'User''s Address Line 2' , `city` VARCHAR(255) NOT NULL COMMENT 'User''s Address City' , `state` VARCHAR(255) NOT NULL COMMENT 'User''s Address State' , `pincode` INT(11) UNSIGNED NOT NULL COMMENT 'User''s Address Pincode' , `email` VARCHAR(255) NOT NULL COMMENT 'User''s Contact Email' , `mobile` INT(11) UNSIGNED NULL COMMENT 'User''s Contact Mobile' , `phone` INT(11) UNSIGNED NULL COMMENT 'User''s Contact Phone' , `sex` ENUM('M','F','NS') NOT NULL COMMENT 'User''s Sex' , `dateOfBirth` DATE NOT NULL COMMENT 'User''s Date of Birth' , `designation` VARCHAR(255) NULL COMMENT 'User''s Designation' , `dateOfEntry` TIMESTAMP on update CURRENT_TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT 'User''s Date of Entry' , PRIMARY KEY (`BBZUID`(9)) , UNIQUE (`username`(30)) ) ENGINE = InnoDB COMMENT = 'User''s Database';
答案 0 :(得分:9)
您必须删除密钥的长度:
PRIMARY KEY (`BBZUID`) ,
而不是
PRIMARY KEY (`BBZUID`(9)) ,
答案 1 :(得分:1)
SQL代码
而不是主键(' id'(10));
它将是主键(' id');
答案 2 :(得分:0)
更改SQL语法的这一部分:
主键(BBZUID
(9))->主键(BBZUID
)
