| | Effectiveness This editorial was originally published on Nov 7, 2013. It is being rerun as Steve is on vacation. I saw a great quote recently on an internal email at Red Gate. We had deployed a new feature to a website, the application seemed to be working, but someone questioned the architecture of the implementation. The person who was in charge of the project sent this back at the end of an explanation: "It’s a little clunky, but we decided it was better to get it done than make it perfect." That's a great quote. In fact, that's what I've aimed for in most of my career. Move things forward, get them done in an effective manner. That's what I've tried to do as long as I've been in technology. Examine a problem, consider various solutions, and then choose one to move forward with. At the end of the day, as has been said by many people, "shipping is a feature". This doesn't mean giving up on quality or accepting anything, but it does mean that you continue to move forward. You may make compromises on code quality, but small compromises. Your code has to still solve the problem. Your database still has to handle the load. You still need quality work, but a solution you can get done quickly that performs 10% worse may be better than a faster solution that takes twice as long to develop. Lots of code lives in systems for years. We want this code to be "good" in that it needs to work, handle the load, and contain few bugs. However lots of code also gets refactored over time. We should minimize bad code as much as possible, but less than perfect code isn't bad. Sometimes it's just a little clunky, but it gets the job done.

| | | Vishnu Gupthan from SQLServerCentral.com How to insert data into a SQL Server Table using Powershell using Invoke-SQLcmd Commandlet Being a SQL Server DBA , while dealing with reporting and automation stuffs, it is quite needed to insert the data into SQL Server table using shell or batch scripts Here , we are going to use powershell to insert the data using a commandlet in Powershell called Invoke-SQLCmd. There are many other options also to do the same but we are focusing Invoke-SQLcmd to perform this in this session. What we are doing Insert the Services running in a windows server to a table in SQL Server. What we need SQL Server installed in the machine\Server. How we are doing 1. Take the output of the Get-Services command. 2. Insert the data to SQL Server table ‘ServiceTable’ Steps - This is how the Get-Service commandlet output looks like.  Script to extract the details and insert into SQL server table.  Powershell Script $services=Get-Service foreach($service in $services) { $ser=$service.Status $name=$service.name $disname=$service.DisplayName $insertquery=" INSERT INTO [dbo].[ServiceTable] ([Status] ,[Name] ,[DisplayName]) VALUES ('$ser' ,'$name' ,'$disname') GO " Invoke-SQLcmd -ServerInstance 'KILIKOOD-PC\MSSQLSERVER,1433' -query $insertquery -U sa -P test123 -Database Fantasy } Table ServiceTable looks like below :  Notes : Normally Invoke-SQLcmd should work if you have SQL Server installed in the server as the SQL Server Management Objects will get installed along with it. If you still have any issues in loading Invoke-SQLcmd , please follow the below steps as referred in the link click here - Install SQL Server 2008 R2 Management Objects using Web PI (I'm not sure about versions prior to 2008 R2... if you have more info, please let us know in the comments)
- Install 'Windows PowerShell Extensions for SQL Server' from the Microsoft® SQL Server® 2008 R2 Feature Pack page (it's about halfway down the page). Make sure you pick the correct flavor for your instance (32 or 64 bit).
- Run these two commands before calling invoke-sqlcmd in your script:
Add-PSSnapin SqlServerCmdletSnapin100
Add-PSSnapin SqlServerProviderSnapin100
For SQL Server 2012, MSFT have switched to a single module. Run this instead: More »
