importing MySQL dump to SQL Server 2012
I recently had to do essentially the same thing, except that I wanted to migrate MySQL tables and data to SQL Server. I tried:


using phpMyAdmin to Export the table definitions with "MSSQL" compatibility: The resulting SQL script would not execute in SQL Server Management Studio (SSMS) due to syntax errors.
using HeidiSQL to export the MySQL database directly to SQL Server: HeidiSQL also generated SQL statements that SQL Server would not accept.
using MySQL Workbench: I could not find a way to migrate a database from MySQL to SQL Server.
using MySQL ODBC and the SQL Server Import and Export Wizard: The wizard crashed (i.e., the Windows "[Application name] has stopped working..." error) when trying to access the MySQL database.


The only method that didn't fail outright was to pull the tables from MySQL into a Microsoft Access .mdb file (!) via MySQL ODBC, then import that into SQL Server. 

However, even that was an incomplete solution because the transfer from MySQL to Access omitted all of the primary keys, indexes, and AUTO_INCREMENT attributes. Still, it did transfer the tables and data, which was my main objective. I just had to write some T-SQL to re-create the indexes and whatnot.

Since you don't need to transfer any data you might want to consider just hacking the mysqldump SQL code (good old Find &amp; Replace...) to the point where SQL Server will execute it.
