Constraint Value

Constraint Value

The constraint value represents a constant value to which you want to compare the field values. For example, you might want to verify that all values in the ORDER_DATE field fall between January 1, 2020 and December 31, 2020. Or, you might want to verify that the minimum ORDER_ID number is greater than 1000.
The constraint value must be a string, numeric, or datetime constant. The datatype of the constraint value depends on the test.
The following table lists the constraint value datatype allowed for each test:
Test
Datatype
COUNT, COUNT_DISTINCT, COUNT_ROWS
Integer
MIN, MAX, SUM, VALUE
Same as the
Field
datatype.
FORMAT
String
AVG
Double
UNIQUE, NOT_NULL, NOT_BLANK
These tests do not use a constraint value.
Enter a constraint value in the
Constraint Value
field. Enter a constant or list of constants separated by commas.
The number of constants you enter as the constraint value depends on the operator you use:
Arithmetic operator such as =, <>, or ~
Enter a single constant.
Between or Not Between operator
Enter two constants separated by a comma.
In or Not In operator
Enter multiple constants separated by commas.
Enclose each string value, datetime value, or format pattern within single quotes. Datetime values must match the PowerCenter standard datetime format of MM/DD/YYYY HH24:MI:SS.
