Broadband connection to SQL Azure database failed

This post is showing an error when you have a slow wireless broadband then you would never be connected to SQL Azure database. I was connecting to SQL Azure database using Azure Data Studio. It was the same when I used SQL Server Management Studio. When you see the error “A connection was successfully established with the server but then an error occurred during the login process.” I have confirmed this was caused by my slow wireless broadband (Celcom). I was in a place called Mulu at that point of time.

Azure Data Studio vs SQL Server Management Studio part 3

This post continue to look at the differences between Azure Data Studio and SQL Server Management Studio. This post is focus on Security. In SSMS you can find a dedicated Security node.

In ADS is the same, it has a dedicated Security node.

When you right click a credential such as sa. There will be a list of shortcut menu. The most important item in the list is actually the Properties. That allow you to grant permission to a database, define the role(s) for that credential and more.

In ADS, beside a Refesh, when I was right clicking the credential, there is nothing else.

In SSMS, when you click on a security role. There is also a list of item display in a shortcut menu.

In ADS, it is still only the Refresh for now. Whether Microsoft going to extension the features?

SQL Server query for the most used Tables and Index

This short post consist of the SQL Server Query to find out most used Tables and most used Indexes.

— most use table

SELECT
db_name(ius.database_id)
AS DatabaseName,t.NAME
AS TableName,SUM(ius.user_seeks + ius.user_scans + ius.user_lookups)
AS NbrTimesAccessed FROM
sys.dm_db_index_usage_stats ius INNER JOIN
sys.tables t ON t.OBJECT_ID
= ius.object_id WHERE database_id =
DB_ID(‘Tablename’) GROUP
BY database_id, t.name ORDER
BY
SUM(ius.user_seeks + ius.user_scans + ius.user_lookups)
DESC

— most use Indexes

SELECT
db_name(ius.database_id)
AS DatabaseName,t.NAME
AS TableName,i.NAME
AS IndexName,i.type_desc
AS IndexType, ius.user_seeks + ius.user_scans + ius.user_lookups AS NbrTimesAccessed FROM
sys.dm_db_index_usage_stats ius INNER
JOIN
sys.indexes i ON i.OBJECT_ID
= ius.OBJECT_ID
AND i.index_id = ius.index_id INNER
JOIN
sys.tables t ON t.OBJECT_ID
= i.object_id WHERE database_id =
DB_ID(‘Tablename’) ORDER
BY ius.user_seeks + ius.user_scans + ius.user_lookups DESC

Machine Learning Service in SQL Server 2017

This post shows you how to start with Machine Learning Service in SQL Server 2017. One of the feature added to SQL Server 2017 is machine learning. There are two language of choices R and Python. I am a R user than Python user. So this post is more R oriented. Many people don’t know where to start, like me, few weeks back. First you must install SQL Server with Machine Learning Services here:

https://docs.microsoft.com/en-us/sql/advanced-analytics/install/sql-machine-learning-services-windows-install?view=sql-server-2017

Once you have done the installation make sure the Windows Service MSSQLLaunchpad is running. Start SQL Server Management Studio. Type this in the query pane.

EXEC
sp_configure
‘external scripts enable’, 1 RECONFIGURE
WITH
OVERRIDE

Test the R language is working in SQL Server 2017.

EXECUTE
sp_execute_external_script @language =
N’R’, @script =
N’ a <- 1 b <- 2 c <- a/b d <- a*b print(c, d)’
