![]() ![]() A Quick Review of the CSV FileĬSV stands for comma-separated values. Then, we cut to the chase and export data to a CSV file using both SQL Server Management Studio (SSMS) and SQL Command Line (SQLCMD).īefore we start, we encourage you to install the Microsoft SQL Server database along with MS SQL Server Management Studio so you can follow along.Ĭheck out our course on SQL Basics in MS SQL Server, which covers basic concepts of T-SQL including querying and aggregating data, JOINs, subqueries, and more. In this article, we first recall what a CSV file is and why you would want to export data in this format from an MS SQL Server database. Follow this article to learn how to export data from Microsoft SQL Server to a CSV file. If intcount - 1 thenĪ.write """" & showList.fields(intcount).value & ""","Ī.write """" & showList.fields(intcount).When working with data and databases, it is common to export data for further processing or transport to another database. If intcount -1 thenĪ.write """" & showList.fields(intcount).name & ""","Ī.write """" & showList.fields(intcount).name & """"įor intcount = 0 to - 1 bcp /?įor example: usage: bcp SERVER=" & dbHost & " PORT=3306 DATABASE=" & dbName & " UID=" & dbUser & " PASSWORD=" & dbPass & " OPTION=3") Run this from your command line to check the syntax. Is this not bcp was meant for? bcp "select col1, col2, col3 from " queryout "c:\MyData.txt" -c -t"," -r"\n" -S ServerName -T To adapt the example for SQL Server 20 R2, remove the #Requires line entirely and use the sqlps.exe utility instead of the standard PowerShell host. # actual Invoke-Sqlcmd |Export-Csv pipelineĪ full path for Export-Csv's -Path parameter is safest if you are stuck using the old SQLPS module. # dummy query to catch initial surprise directory change So you'll need to change the #Requires line above to: Push-Location $PWD ![]() When the module is imported, it changes the current location to SQLSERVER:\. SQL Server 2012 instead has the old SQLPS module. Differences between SQL Server versionsĪs of SQL Server 2016, Invoke-Sqlcmd ships as part of the SqlServer module. If that's a problem, you could try the other tools, or roll your own efficient version of Invoke-Sqlcmd using class. It may not work smoothly for billions of rows. Make sure you have enough memory for the whole result set you want to export. The main disadvantage is that Invoke-Sqlcmd reads the whole result set before passing it along the pipeline. The Export-Csv cmdlet handles it all for you. The main advantage of this solution over sqlcmd.exe or bcp.exe is that you don't have to hack the command to output valid CSV. Use UTF8 instead to preserve all characters and stay compatible with most other tools. By default Export-Csv outputs only ASCII characters and replaces all others with question marks. The -Encoding parameter works like the -f or -u parameters of sqlcmd.exe. The -Path parameter works like the -o parameter of sqlcmd.exe. It lets you know the type of the object when you deserialize it later with Import-Csv, but it confuses tools that expect standard CSV. By default the cmdlet writes a header with type information. ![]() The -NoTypeInformation parameter suppresses extra output that is not part of the CSV format. Pass it the name of the server that contains the data to be exported.Įxport-CSV is a PowerShell cmdlet that serializes generic objects to CSV. The -Server parameter works like the -S parameter of sqlcmd.exe. Pass it the name of the database that contains the data to be exported. The -Database parameter works like the -d parameter of sqlcmd.exe. ![]() Pass it a SQL query that describes the data you want to export. The -Query parameter works like the -Q parameter of sqlcmd.exe. Invoke-Sqlcmd is the PowerShell equivalent of sqlcmd.exe. Invoke-Sqlcmd -Query "SELECT * FROM DimDate " ` With PowerShell you can solve the problem neatly by piping Invoke-Sqlcmd into Export-Csv. ![]()
