PARAMETERS

-AllConstraints [<Switch>]

Checks all enabled and disabled constraints on the table if the table name is specified or if all tables are

checked;

Otherwise, checks only the enabled constraint.

Has no effect when a constraint is specified



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-AllErrorMessages [<Switch>]

Returns all rows that violate constraints in the table that is checked.

The default is the first 200 rows.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Database [<System.String[]>]

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.

Accept wildcard characters? false



-NoInformationalMessages [<Switch>]

Suppresses all informational messages.



Required? false

Accept wildcard characters? false



-Object [<String>]

The table or constraint to be checked.

When table_name or table_id is specified, all enabled constraints on that table are checked.

When constraint_name or constraint_id is specified, only that constraint is checked.

If neither a table identifier nor a constraint identifier is specified, all enabled constraints on all tables

in the current database are checked.



Required? false

Position? named

Default value
