.SYNOPSIS
Runs a T-SQL script.
.DESCRIPTION
Runs a T-SQL script. Invoke-Sqlcmd2 only returns message output, such as the output of PRINT statements when -verbose parameter is specified.
Paramaterized queries are supported.
.INPUTS
None
You cannot pipe objects to Invoke-Sqlcmd2
.OUTPUTS
System.Data.DataTable
.EXAMPLE
Invoke-Sqlcmd2 -ServerInstance "MyComputer\MyInstance" -Query "SELECT login_time AS 'StartTime' FROM sysprocesses WHERE spid = 1"
This example connects to a named instance of the Database Engine on a computer and runs a basic T-SQL query.
StartTime
-----------
2010-08-12 21:21:03.593
.EXAMPLE
Invoke-Sqlcmd2 -ServerInstance "MyComputer\MyInstance" -InputFile "C:\MyFolder\tsqlscript.sql" | Out-File -filePath "C:\MyFolder\tsqlscript.rpt"
This example reads a file containing T-SQL statements, runs the file, and writes the output to another file.
.EXAMPLE
Invoke-Sqlcmd2 -ServerInstance "MyComputer\MyInstance" -Query "PRINT 'hello world'" -Verbose
This example uses the PowerShell -Verbose parameter to return the message output of the PRINT command.
VERBOSE: hello world
