// Fix: No Entity Framework provider found for the ADO.NET provider with invariant name 'MySql.Data.MySqlClient'
DbConfiguration.SetConfiguration(new MyDbConfiguration());
var createTableOperation = new CreateTableOperation("customers");
var createTable = new CreateTableOperation("customers");
createTable.Columns.Add(
new ColumnModel(PrimitiveTypeKind.Int64)
{
Name = "id",

IsIdentity = true,
IsNullable = false,
});
createTable.Columns.Add(new ColumnModel(PrimitiveTypeKind.String)
{
Name = "name",
StoreType = "varchar",
MaxLength = 45,
DefaultValue = null,
});
createTable.PrimaryKey = new AddPrimaryKeyOperation();
createTable.PrimaryKey.Columns.Add("id");
var sqlGenerator = new MySqlMigrationSqlGenerator();
var sqlStatements = sqlGenerator.Generate(
new[] { createTableOperation }, "MySql.Data.MySqlClient"
);
// Return the first SQL statement as a string
foreach (var sqlStatement in sqlStatements)
{
var sql = sqlStatement.Sql.ToString();
Console.WriteLine(sql);
}
Result
create table `customers` (`id` int unsigned not null auto_increment ,`name` varchar(45) , KEY (`id`)) engine=InnoDb auto_increment=0;
