Description |
|---|
| COALESCE Function |
Function returns the first non-missing value found in an array of columns.
See COALESCE Function.
|
| RAND Function |
The RAND function generates a random real number between 0 and 1. The function accepts an optional integer parameter, which causes the same set of random numbers to be generated with each job execution.
See RAND Function.
|
| RANDBETWEEN Function |
Generates a random integer between a low and a high number. Two inputs may be Integer or Decimal types, functions returning these types, or column references.
See RANDBETWEEN Function.
|
| PI Function |
The PI function generates the value of pi to 15 decimal places: 3.1415926535897932.

|
| IF Function |
The IF function allows you to build if/then/else conditional logic within your transforms.
See IF Function.
|
| CASE Function |
The CASE function allows you to perform multiple conditional tests on a set of expressions within a single statement. When a test evaluates to true, a corresponding output is generated. Outputs may be a literal or expression.
See CASE Function.
|
| Ternary Operators |
Ternary operators allow you to build if/then/else conditional logic within your transforms. Please use the IF function instead.
See Ternary Operators.
