Methods to Insert Data into SQL Server

April 10, 2019 by

Summary

There are a variety of ways of managing data to insert into SQL Server. How we generate and insert data into tables can have a profound impact on performance and maintainability! This topic is often overlooked as a beginner’s consideration, but mistakes in how we grow objects can create massive headaches for future developers and administrators.

Securely Working with Invoke-SqlCmd

March 26, 2019 by

We have a convenient tool for working with PowerShell and SQL Server when using Invoke-SqlCmd. As we saw when running statements, we can run DDL and DML changes with the command without writing our own custom scripts. This carries advantages when we need to quickly develop with PowerShell, but it can come with drawbacks on security if we’re not careful how we use this function. We’ll look at security when using this function by starting with a few examples of what we can do when we have unlimited access along with how we can design to limit our environment to be strict with our use of this tool.

Working with PowerShell’s Invoke-SqlCmd

March 18, 2019 by

PowerShell features many one-line commands for working with SQL Server, one of which is Invoke-SqlCmd. This tool can be useful in many development contexts where we need to quickly execute scripts or test code and it helps to know some of the parameters we’ll often use. In addition, because we may want a custom script using some of the underlying .NET objects, we’ll look at an alternative where we will be able to create a custom PowerShell script that connects to SQL Server in order to run commands. The latter can be useful because one-line scripts have a tendency to change in future versions of PowerShell and working with the library directly can sometimes avoid this challenge.

Using Python SQL scripts for Importing Data from Compressed files

March 4, 2019 by

Using Python SQL scripts is a powerful technical combination to help developers and database administrators to do data analytics activities. Python provides many useful modules to perform data computation and processing of data efficiently. We can run Python scripts starting from SQL Server 2017. We can create the ETL solutions to extract data from various sources and insert into SQL Server.

Export SQL Server FILESTREAM Objects with PowerShell and SSIS

February 14, 2019 by

In this series of articles on SQL Server FILESTREAM (see TOC at bottom), we explored various ways to store unstructured data in the file system with the metadata in SQL Server tables. If we have a large number of objects in the file system, it is advisable to use the fast disk for storage purpose. It is faster and provides better IO in comparison with the traditional file system.

Power BI Desktop and Python; like Peanut Butter and Chocolate

February 13, 2019 by

Power BI Desktop helps to visualize complex data with the help of inbuilt and custom visualizations. It allows integrating data from the various data sources and preparing visualization from it.

Microsoft recently integrated the Python programming language in the Power BI. Python is a powerful object-oriented language and is used by the data analyst and scientist to analyze complex datasets. We can now use the Python as a preview feature in the Power BI August 2018 release onwards. We can now use Python scripts to generate custom visualization. The combination of these technologies is akin to 1 + 1 = 3 or like the famous ad for Reese’s Peanut butter cups, when chocolate was introduced to Peanut Butter 😉
