Question

I have a MSSQL queries file(.sql), now I need to convert it to MYSQL queries.
Please help me. The script like this:

CREATE TABLE [dbo].[Artist](
    [ArtistId] [int] IDENTITY(1,1) NOT NULL,
    [Name] [nvarchar](120) NULL,
PRIMARY KEY CLUSTERED 

(
    [ArtistId] ASC

)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]

) ON [PRIMARY]

If you want to convert the DDL by hand, then you can do this by building up rules on a case by case basis, e.g. as follows:

• [] need to be replaced with backticks
• IDENTITY(1,1) can be replaced with AUTO_INCREMENT
• Most of the ANSI options and Device settings
  can be ignored (these seem to be present only because the table has
  been rescripted)
• w.r.t. dbo, MySQL doesn’t implement schemas in the same way as SQL Server – you will either need to separate schemas into databases, or drop the schema, or mangle the schema name into the tablename (e.g. as a Prefix)

This will leave you with something like the following:

CREATE TABLE `Artist`(
    `ArtistId` int NOT NULL AUTO_INCREMENT,
    `Name` nvarchar(120) NULL,
    PRIMARY KEY CLUSTERED 
    (
       `ArtistId` ASC
    )
);

However, it is usually much easier to do this migration with a migration tool – search for the section on How to Transition from SQL Server to MySQL
