/**
|
|
* Specific support for SQL Azure databases running on Windows Azure.
|
|
* "sqlsrv" for PHP MUST be installed to use SQL Azure. It does not support
|
|
* the mssql_*() functions in PHP, as SQL Azure is Windows only.
|
|
*
|
|
* Some important things about SQL Azure:
|
|
*
|
|
* Selecting a database is not supported.
|
|
* In order to change the database currently in use, you need to connect to
|
|
* the database using the "Database" parameter with sqlsrv_connect()
|
|
*
|
|
* Multiple active result sets are not supported. This means you can't
|
|
* have two query results open at once.
|
|
*
|
|
* Fulltext indexes are not supported.
