Creating a Key Lookup
29
Purpose of Key Lookup
• Another Way to Join to a Table
• Primary use is to provide values from Table of Values
• Use when an Equijoin may eliminate rows
30
Select Key Lookup

Data Transformation
57
Use of Expressions
• “Clean” the Data, handle nulls, etc.
• Conform the Data – all CAPS, etc
• Conditional Logic – if then else
• Dig out data from strings – Substring
• Etc
58
Populate Expression

Edit Output Fields
61
Common Expression Transforms
• Trim off Blanks from character fields TRIM(INGRP1.CHAR_FLD_NAME)
• Select portions of fields SUBSTR(INGRP1.NUMBER_FLD_NAME,1,5)
• Handle Null Values NVL(INGRP1.FLD_NAME,’U’)
• Convert to Upper Case UPPER(INGRP1.FLD_NAME)
• Convert Characters to Numbers TO_NUMBER(INGRP1.FLD_NAME)• If … then …Else Logic
CASE Statement• Compound Expressions and Functions
