function Invoke-Sqlcmd2 { <# .SYNOPSIS Runs a T-SQL script. .DESCRIPTION Runs a T-SQL script. Invoke-Sqlcmd2 runs the whole script and only captures the first selected result set, such as the output of PRINT statements when -verbose parameter is specified. Parameterized queries are supported. Help details below borrowed from Invoke-Sqlcmd .PARAMETER ServerInstance Specifies the SQL Server instance(s) to execute the query against. .PARAMETER Database Specifies the name of the database to execute the query against. If specified, this database will be used in the ConnectionString when establishing the connection to SQL Server. If a SQLConnection is provided, the default database for that connection is overridden with this database. .PARAMETER Query Specifies one or more queries to be run. The queries can be Transact-SQL, XQuery statements, or sqlcmd commands. Multiple queries in a single batch may be separated by a semicolon. Do not specify the sqlcmd GO separator (or, use the ParseGo parameter). Escape any double quotation marks included in the string. Consider using bracketed identifiers such as [MyTable] instead of quoted identifiers such as "MyTable". .PARAMETER InputFile Specifies the full path to a file to be used as the query input to Invoke-Sqlcmd2. The file can contain Transact-SQL statements, XQuery statements, sqlcmd commands and scripting variables. .PARAMETER Credential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) SECURITY NOTE: If you use the -Debug switch, the connectionstring including plain text password will be sent to the debug stream. .PARAMETER Encrypt If this switch is enabled, the connection to SQL Server will be made using SSL. This requires that the SQL Server has been set up to accept SSL requests. For information regarding setting up SSL on SQL Server, see https://technet.microsoft.com/en-us/library/ms189067(v=sql.105).aspx .PARAMETER QueryTimeout Specifies the number of seconds before the queries time out. .PARAMETER ConnectionTimeout Specifies the number of seconds before Invoke-Sqlcmd2 times out if it cannot successfully connect to an instance of the Database Engine. The timeout value must be an integer between 0 and 65534. If 0 is specified, connection attempts do not time out. .PARAMETER As Specifies output type. Valid options for this parameter are 'DataSet', 'DataTable', 'DataRow', 'PSObject', and 'SingleValue' PSObject output introduces overhead but adds flexibility for working with results: http://powershell.org/wp/forums/topic/dealing-with-dbnull/ .PARAMETER SqlParameters Specifies a hashtable of parameters for parameterized SQL queries. http://blog.codinghorror.com/give-me-parameterized-sql-or-give-me-death/ Example: .PARAMETER AppendServerInstance If this switch is enabled, the SQL Server instance will be appended to PSObject and DataRow output. .PARAMETER ParseGo If this switch is enabled, "GO" statements will be handled automatically. Every "GO" will effectively run in a separate query, like if you issued multiple Invoke-SqlCmd2 commands. "GO"s will be recognized if they are on a single line, as this covers the 95% of the cases "GO" parsing is needed Note: Queries will always target that database, e.g. if you have this Query: USE DATABASE [dbname] GO SELECT * from sys.tables and you call it via Invoke-SqlCmd2 -ServerInstance instance -Database msdb -Query ... you'll get back tables from msdb, not dbname. .PARAMETER SQLConnection Specifies an existing SQLConnection object to use in connecting to SQL Server. If the connection is closed, an attempt will be made to open it. .INPUTS None You cannot pipe objects to Invoke-Sqlcmd2 .OUTPUTS As PSObject: System.Management.Automation.PSCustomObject As DataRow: System.Data.DataRow As DataTable: System.Data.DataTable As DataSet: System.Data.DataTableCollectionSystem.Data.DataSet As SingleValue: Dependent on data type in first column. .EXAMPLE Invoke-Sqlcmd2 -ServerInstance "MyComputer\MyInstance" -Query "SELECT login_time AS 'StartTime' FROM sysprocesses WHERE spid = 1" 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" 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 Uses the PowerShell -Verbose parameter to return the message output of the PRINT command. VERBOSE: hello world .EXAMPLE Invoke-Sqlcmd2 -ServerInstance MyServer\MyInstance -Query "SELECT ServerName, VCNumCPU FROM tblServerInfo" -as PSObject | ?{$_.VCNumCPU -gt 8} Invoke-Sqlcmd2 -ServerInstance MyServer\MyInstance -Query "SELECT ServerName, VCNumCPU FROM tblServerInfo" -as PSObject | ?{$_.VCNumCPU} This example uses the PSObject output type to allow more flexibility when working with results. If we used DataRow rather than PSObject, we would see the following behavior: Each row where VCNumCPU does not exist would produce an error in the first example Results would include rows where VCNumCPU has DBNull value in the second example .EXAMPLE 'Instance1', 'Server1/Instance1', 'Server2' | Invoke-Sqlcmd2 -query "Sp_databases" -as psobject -AppendServerInstance This example lists databases for each instance. It includes a column for the ServerInstance in question.
