Microsoft SQL Server<\/strong> and MySQL<\/strong> are among the best relational database management systems (RDBMS) but with one important difference. MS SQL is a proprietary software of Microsoft while Oracle MySQL is open-source and free. This is one of the reasons why companies migrate to MySQL to manage their data. Another important reason that drives the companies to migrate to MySQL is the cost. To be brief, looking at the top editions of these two DBMS, the Enterprise edition of Microsoft SQL Server costs more than the same edition of MySQL.<\/p>

The migration process, however, is an important process that must be analyzed and planned properly. For example, an aspect to keep in mind is that the data types used by the DBMS may differ. In addition, this process involves not only data but also all the other objects, such as functions, procedures, etc.<\/p>

Ways to Convert MS SQL to MySQL<\/h2>

There are different ways to convert or migrate data from MS SQL to MySQL.<\/strong><\/p>

Convert MS SQL to MySQL Manually<\/h3>

Data types in Microsoft SQL Server and MySQL are sometimes different. So, to avoid errors or loss of data, mapping between data types must be done. You can refer the official document<\/a> to know the data type mapping between these two DBMS. For example, Varchar and NVarchar MS SQL data types can become a TEXT data type depending on the field length in MS SQL.  <\/p>

The first step is to convert the database schema using the correct data types. You also need to consider other aspects, such as whether the field you are considering accepts NULL values and the field has a primary key.<\/p>

Since both RDMS adhere to and support much of the ANSI ISO standard<\/strong>, when you create the tables using the SQL “CREATE TABLE” command, the syntax will be similar.<\/p>

For example, below is the schema of the table ‘Customer’ in MS SQL Server.<\/strong><\/p>

Below is the schema of the same table in MySQL.<\/p>
