Azure SQL Database General Guidelines and Limitations
Please do following checks when you create database object script using "Generate Script" wizard.
1. Delete all instances of SET ANSI_NULLS ON.
2. SQL Azure hides all hardware-specific access and information. There is no concept of PRIMARY or file groups because disk space is handled by Microsoft, so this option isn’t required.
Delete all instances of ON [PRIMARY].
3. Delete all instance of PAD_INDEX = OFF as well as ALLOW_ROW_LOCKS = ON and ALLOW_PAGE_LOCKS = ON.
4. The NEWSEQUENTIALID() function isn’t supported in SQL Azure because there is no CLR support in SQL Azure, and thus all CLR-based types aren’t supported. The NEWSEQUENTIALID() return value is one of those typesIn the Users table, modify the rowguid column, changing DEFAULT NEWSEQUENTIALID() to NULL.
5. In the stored procedure, remove the ENCRYPTION clause.
6. SQL Azure currently supports only clustered tables. SQL Azure doesn’t support heap tables. A heap table is one without a clustered index.
7.Microsoft Azure SQL Database supports only SQL Server Authentication. Windows Authentication (integrated security) is not supported. Users must provide credentials (login and password) every time they connect to Microsoft Azure SQL Database.
8.Microsoft Azure SQL Database does not support distributed transactions, which are transactions that affect several resources
9.Microsoft Azure SQL Database does not allow setting the collation at the server level.
10.Microsoft Azure SQL Database provides two database editions: Web Edition and Business Edition. Web Edition databases can grow up to a size of 5 GB and Business Edition databases can grow up to a size of 150 GB.
