Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Alias
Required True
Pipeline true (ByValue)
Default Value

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance.

Alias
Required False
Pipeline false
Default Value
-Database

The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed.

Alias
Required False
Pipeline false
Default Value
-ExcludeDatabase

The database(s) to exclude - this list is auto-populated from the server

Alias
Required False
Pipeline false
Default Value
-MaxResultsPerDb

Allows you to limit the number of results returned, as many systems can have very large amounts of query plans. Default value is 100 results.

Alias
Required False
Pipeline false
Default Value 100
-MinExecs

Allows you to limit the scope to queries that have been executed a minimum number of time. Default value is 100 executions.

Alias
Required False
Pipeline false
Default Value 100
-MinExecMs

Allows you to limit the scope to queries with a specified average execution time. Default value is 500 (ms).

Alias
Required False
Pipeline false
Default Value 500
-ExcludeSystem

Allows you to suppress output on system databases

Alias ExcludeSystemDatabases
Required False
Pipeline false
Default Value False
-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.

Alias
Required False
Pipeline false
Default Value False
