How to use BULK INSERT to import data locally and in Azure

November 16, 2017 by

Introduction

BULK INSERT is a popular method to import data from a local file to SQL Server. This feature is supported by the moment in SQL Server on-premises.

However, there is a new feature that is supported only in SQL Server 2017 on-premises. This feature allows importing data from a file stored in an Azure storage account to SQL Server on-premises using BULK INSERT. This feature will be supported in Azure SQL versions in the future.

In this article, we will show two examples. The first example will show how to use the traditional BULK INSERT statement from a local CSV file to Azure and the second example will show how to import data from a CSV file stored in Azure to SQL Server on-premises.

We can see many articles which discuss the process of configuring Log shipping using T-SQL or SSMS.

An overview of Python vs PowerShell for SQL Server Database Administration

November 2, 2017 by

Today, Microsoft claims that Linux runs like a First-Class citizen on Azure, .NET Core has been open-sourced, and has been ported over to Linux, taking PowerShell along. PowerShell runs really well on Ubuntu, CentOS, RedHat Linux, and even Mac OS X. There are Alpha builds available for a few other platforms as well, all available for exploitation under the MIT License on GitHub. “Manage anything, anywhere” is what Microsoft is offering to its customers. Keeping with that, we now have:

How to build a SQL Server Virtual Lab with AutomatedLab in Hyper-V

October 30, 2017 by

There are often situations I want to test a piece of software or the latest version of SQL Server for a proof of concept, maybe even the new Power BI Report Server. I could install these locally, where I’ve likely got previous SQL installs or an already burgeoning system. You could be lucky that you have access to Virtual Machines that you can build out for the task. Now add a few hours to setup Windows or even just the applications themselves. Those VMs may be in Azure, or AWS, now add a few £’s or $’s every time you want to work on something. Did you remember to turn them off?

Commonly used SQL Server Constraints: NOT NULL, UNIQUE and PRIMARY KEY

October 25, 2017 by

SQL Server Constraints are predefined rules and restrictions that are enforced in a single column or multiple columns, regarding the values allowed in the columns, to maintain the integrity, accuracy, and reliability of that column’s data. In other words, if the inserted data meets the constraint rule, it will be inserted successfully. If the inserted data violates the defined constraint, the insert operation will be aborted.

ETL optimization using SQL Server TRY Functions

October 24, 2017 by

Introduction

An enterprise data warehouse ETL solution typically includes, amongst other steps, a data transformation step that converts source data from one data type into another. It is during this step that type conversion errors may occur and depending on the type of exception handling techniques implemented in the ETL solution (or lack thereof), frustration may occur for both ETL developers and DBAs when trying to identify and resolve type conversion errors. In this article we take a look at a trio of SQL Server built-in functions that were introduced in SQL Server 2012, namely, TRY_PARSE, TRY_CAST, and TRY_CONVERT and how they could be utilized to reduce type conversion errors in ETL solutions and thereby saving developers needless troubleshooting exercise.

Why would a SQL Server DBA be interested in Python?

October 23, 2017 by

If we follow blogs and publications on the technological advancement with respect to SQL, we notice the increase in the number of references to Python, of late. Often, that makes us think:

  • Why so much emphasis on Python these days?
  • Isn’t knowing PowerShell scripting sufficient for the automation requirements of today?
  • Is it the time DBAs started learning a programming language such as Python in order to handle their day-to-day tasks more efficiently?
  • Why do so many job postings these days include “knowledge of scripting” as a requirement?
  • Is all of this happening because the paradigm is shifting? Can’t the current Microsoft-specific languages such as PowerShell handle the shift?

Monitoring SQL Server database status changes using T-SQL and PowerShell scripts

October 17, 2017 by

Monitoring a SQL Server database is a critical component of database administration. Ninety percent of the organizations expect the number of databases to increase over the next twelve months.
