转换SQL Server查询到MySQL

Question

这是我在ms sql server中编写的简单查询...现在我需要将此数据库转换为mysql ...建议我以最简单的方式执行此操作...提前致谢

Answer 1

的基本语法应该工作，但是有一个问题，但：

您需要将所有的“内联”为横生键约束任一表中的末端或到ALTER TABLE，如InnoDB的忽略直列约束“附接”到柱：

此外，InnoDB的不能识别或支持“内联参考规范”（如SQL标准中定义的那样），其中引用被定义为列规范的一部分。 InnoDB只有在作为单独的FOREIGN KEY规范的一部分指定时才接受REFERENCES子句。

来源：http://dev.mysql.com/doc/refman/5.5/en/innodb-foreign-key-constraints.html

所以，这种说法

CREATE TABLE GRADE 
(
    LETTER_GRADE CHAR NOT NULL , 
    PERCENTAGE FLOAT NOT NULL, 
    STUDENT_REGNO int CONSTRAINT STUDENT_5 FOREIGN KEY(STUDENT_REGNO) 
    REFERENCES STUDENT(STUDENT_REGNO), 
    COURSE_ID int CONSTRAINT COURSE_1 FOREIGN KEY(COURSE_ID) 
    REFERENCES COURSE(COURSE_ID) 
) 

需要成为：

CREATE TABLE GRADE 
(
    LETTER_GRADE CHAR NOT NULL, 
    PERCENTAGE FLOAT NOT NULL, 
    STUDENT_REGNO int, 
    COURSE_ID int, 
    CONSTRAINT STUDENT_5 FOREIGN KEY(STUDENT_REGNO) REFERENCES STUDENT(STUDENT_REGNO), 
    CONSTRAINT COURSE_1 FOREIGN KEY(COURSE_ID) REFERENCES COURSE(COURSE_ID) 
) 

注意在定位约束定义略有不同。

Answer 2

有没有简单的解决方案 - 你需要手动转换它，手动。创建表的语法或多或少是相同的，你需要改变的是数据类型和约束。您可以检查MySQL参考手册中的所有数据类型和contraint创作语法，发现这里：http://dev.mysql.com/doc/refman/5.0/en/sql-syntax.html

在一个单独的说明，如果你正在寻找从SQL Server迁移到MYSQL（不只是转换查询），尝试寻找这里：http://dev.mysql.com/tech-resources/articles/migrating-from-microsoft.html

 
Migration Tools 
There are a wide variety of tools available to help you migrate a SQL Server or Access database to MySQL. We'll look at several different tools so you can choose the one that best suits your needs. The tools we will look at will include the following: 

MSSQL2MYSQL 
Microsoft DTS 
SQLyog 
Access Export 
Text Import/Export 
SQLYog and the Microsoft DTS wizard offer graphical interfaces that can be used with both MSSQL and Microsoft Access to import tables into MySQL. MSSQL2MYSQL is a script by Michael Kofler that can convert not only the table structure and data, but converts the index information as well. If you use Microsoft Access you may not have access to the above tools, but you can use the data export features of Access.
