Microsoft SQL Server

Microsoft SQL Server

The following table describes the data masking, data subset, data discovery, and data generation operations that you can perform on the Microsoft SQL Server data types when the target is test data warehouse:
Data Types
Test Data Warehouse
Comments
Bigint
Yes
Binary
Yes
Use dictionary generation rule to generate test data.
Use nullification data masking rule to mask the data.
Bit
Yes
Char
Yes
Date
Yes
Datetime
Yes
Datetime2
Yes
Datetimeoffset
Yes
Decimal
Yes
You can enter a precision value up to 28.
Float
Yes
To perform a data masking operation, you must set the precision to less than 28.
When you run a data generation operation, TDM truncates data if the precision is greater than 17.
Image
Yes
Int
Yes
Money
Yes
Nchar
Yes
Ntext
Yes
To perform a reset operation on tables with Ntext data type, create a logical primary key in Test Data Manager if a physical primary key does not exist.
Numeric
Yes
You can enter a precision value up to 28.
Nvarchar
Yes
Real
Yes
When you run a data generation operation, TDM truncates data if the precision is greater than 15.
To perform a reset operation on tables with Real data type, create a logical primary key in Test Data Manager if a physical primary key does not exist.
Smalldatetime
Yes
Smallint
Yes
Smallmoney
Yes
Sql_variant
Yes
You cannot perform a data masking operation.
Text
Yes
To perform a reset operation on tables with Text data type, create a logical primary key in Test Data Manager if a physical primary key does not exist.
Time
Yes
When you enter values in milliseconds, TDM truncates the data.
Tinyint
Yes
Uniqueidentifier
Yes
You cannot assign string masking rule even if the data type is present in the
dataMapping.xml
file.
You cannot perform data generation operations.
Varbinary
Yes
Use dictionary generation rule to generate test data.
Use nullification data masking rule to mask the data.
Varchar
Yes
XML
Yes
You cannot perform a data masking operation.
When the target is test data warehouse, you cannot perform data masking, data subset, data discovery, and data generation operations on the following Microsoft SQL Server data types:
  • Geography
  • Geometry
  • HierarchyID
  • Timestamp
