String Random Generation Parameters

String Random Generation Parameters

Create a random data generation rule for string datatypes.
The following table describes the parameters that you can configure to generate random data for string datatype:
Parameter
Description
Random
A range provided to generate random data. You can select Random to specify the range of the string for data generation.
Minimum Length
The minimum length for the string datatype. Default is 1.
Maximum Length
The maximum length for the string datatype. Default is the maximum value that the column permits.
From Regular Expression
A regular expression to generation random data. You can select From Regular Expression to create fixed percentage of data for generation.
Pattern
A regular expression that describes the format of generated data.
Distribution
The percentage of rows with the regular expression data. If you want to use more expressions, you can add more rows.
Generate Unique Values
Generates unique data values. You cannot generate unique values when you select From Regular Expression.
Null Values
A list of global rules or default rule that are available for the string datatype. A null value is a value that a default rule or a global rule generates in the target columns for the string datatype.
Invalid Values
A list of global rules or default rule that you can select for the string datatype. Any value that is less than the minimum length or more than maximum length for a specified range is not valid. A string that does not match the specified pattern is not valid.
You cannot generate values that are not valid when you select From Regular Expression.
