#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Invoke-DbaSqlQuery { <# .SYNOPSIS A command to run explicit T-SQL commands or files. .DESCRIPTION This function is a wrapper command around Invoke-SqlCmd2. It was designed to be more convenient to use in a pipeline and to behave in a way consistent with the rest of our functions. .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential Credential object used to connect to the SQL Server Instance as a different user. This can be a Windows or SQL Server account. Windows users are determined by the existence of a backslash, so if you are intending to use an alternative Windows connection instead of a SQL login, ensure it contains a backslash. .PARAMETER Database The database to select before running the query. This list is auto-populated from the server. .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 or a GO Escape any double quotation marks included in the string. Consider using bracketed identifiers such as [MyTable] instead of quoted identifiers such as "MyTable". .PARAMETER File Specifies the path to one or several files 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 SqlObject Specify on or multiple SQL objects. Those will be converted to script and their scripts run on the target system(s). .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/ .PARAMETER AppendServerInstance If this switch is enabled, the SQL Server instance will be appended to PSObject and DataRow output. .PARAMETER DatabaseCollection A collection of databases (such as returned by Get-DbaDatabase) .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Database, Query Author: Fred Winmann (@FredWeinmann) Website:
