OWB - Process Flow Parameters and Variables

1 - About

All mapping, activity in OWB is a program and then you can pass them a variable.

For each parameter, Warehouse Builder defines a :

  • Name,
  • Direction,

A direction of IN indicates that the parameter is an input parameter and OUT an output parameter.

And for each parameter, you can specify values for:

  • Binding,

Use binding to pass a parameters to another parameters. If you assign a parameter in Binding, it overrides any text you assign to Value.

  • Literal,

If you type in a value for the parameter in the field Value, indicate whether the value is literal or an expression. The literal data types follow the PL/SQL literal value specification except for calendar data types. These data types are represented in a standard format as the Process Flow interacts with data sources from different locations.

Literal Value Type Format Example
DATE YYYY-MM-DD 21-3-2006
DATE YYYY-MM-DD HH24:MI:SS 21-3-2006 15:45
TIMESTAMP YYYY-MM-DD HH24:MI:SS.FF9 2006-03-21 15:45:00.000000000
TIMESTAMP_TZ YYYY-MM-DD HH24:MI:SS.FF9 TZH:TZM 2006-03-21 15:45:00.000000000 +01:00
DMINVERVAL [+-]DDDDDDDDD HH24:MI.SS.FF9 +000000001 01:01:01.000000001
