NAME Invoke-DbaDbDataGenerator
SYNOPSIS
Invoke-DbaDbDataGenerator generates random data for tables
SYNTAX
Invoke-DbaDbDataGenerator [[-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>]
[[-SqlCredential] <Pscredential>] [[-Database] <System.String[]>] [-FilePath] <System.Object> [[-Locale] <String>]
[[-CharacterString] <String>] [[-Table] <System.String[]>] [[-Column] <System.String[]>] [[-ExcludeTable]
<System.String[]>] [[-ExcludeColumn] <System.String[]>] [[-MaxValue] <Int>] [-ExactLength <Switch>]
[[-ModulusFactor] <Int>] [-EnableException <Switch>] [<CommonParameters>]
DESCRIPTION
Invoke-DbaDbDataMasking is able to generate random data for tables.
PARAMETERS
-CharacterString [<String>]
The characters to use in string data. 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789' by
default
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-Column [<System.String[]>]
Columns to process. By default all the columns will be processed
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-Database [<System.String[]>]
Databases to process through
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.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-ExactLength [<Switch>]
Mask string values to the same length. So 'Tate' will be replaced with 4 random characters.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-ExcludeColumn [<System.String[]>]
Exclude specific columns even if it's listed in the config file.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-ExcludeTable [<System.String[]>]
Exclude specific tables even if it's listed in the config file.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-FilePath [<System.Object>]
Configuration file that contains the which tables and columns need to be masked
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-Locale [<String>]
Set the local to enable certain settings in the masking
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-MaxValue [<Int>]
Force a max length of strings instead of relying on datatype maxes. Note if a string datatype has a lower
MaxValue, that will be used instead.
Useful for adhoc updates and testing, otherwise, the config file should be used.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-ModulusFactor [<Int>]
Calculating the next nullable by using the remainder from the modulus. Default is every 10.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-SqlCredential [<Pscredential>]
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.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-SqlInstance [<Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>]
The target SQL Server instance or instances.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-Table [<System.String[]>]
Tables to process. By default all the tables will be processed
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
<CommonParameters>
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
