![]() The reason for this is to compare how we can run connections to our database. If we try to log onto SQL Server, we see these as the first two options when connecting.įor running our first tests with Invoke-SqlCmd, we’ll connect with three one-line calls each labelled with Query and the number. When we connect to SQL Server, we will generally either use a trusted connection or a SQL Server authenticated user. Invoke-SqlCmd can be a useful tool in some contexts where we’re already using PowerShell, or if we’re running steps through SQL Server Job Agent, where we can run PowerShell scripts. Using ETL as an example, if most of our ETL is T-SQL, we should be careful about introducing extra tools that add more work in troubleshooting. We also want to be careful about using more tools than we need to avoid development complexity. These are examples where we may want a custom script. In some cases, we may want a custom timeout that exceeds the limit, or we may not want to allow user input for the connection string (or other details). When we have no alternative that is as quick or effective for our needs When we’re running a standard script without custom execution, like a stored procedure that executes a transform of our ETL layer, and the execution matches our flow When we need to run a test quickly, such as testing code execution outside SSMS (like executing code on TestServerOne that runs against TestServerTwo) When we consider one-line scripts, we want to consider where these tend to be the most helpful for us: For the examples in this article, we are using PowerShell version 5. PowerShell ISE is included in most versions of Windows along with the PowerShell command line. In all these examples where we call Invoke-Sqlcmd, we are not executing saved scripts, but executing these scripts through PowerShell ISE without saving the script. 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. 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. In addition, because we may want a custom script using some of the underlying. 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. If I hardcode those values in script, then it worked fine.PowerShell features many one-line commands for working with SQL Server, one of which is Invoke-SqlCmd. ![]() Server Native Client 10.0 : A network-related or instance-specificĮrror has occurred while establishing a connection to SQL Server.
