NAME Get-DbaSchemaChangeHistory



SYNOPSIS

Gets DDL changes logged in the system trace.





SYNTAX

Get-DbaSchemaChangeHistory [-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>

[[-SqlCredential] <Pscredential>] [[-Database] <System.Object[]>] [[-ExcludeDatabase] <System.Object[]>] [[-Since]

<Dbadatetime>] [[-Object] <System.String[]>] [-EnableException <Switch>] [<CommonParameters>]





DESCRIPTION

Queries the default system trace for any DDL changes in the specified time frame



Only works with SQL 2005 and later, as the system trace didn't exist before then





PARAMETERS

-Database [<System.Object[]>]

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

be processed.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EnableException [<Switch>]

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.
