| 5.5 Attribute Questions: Select by
Condition |
|
| A question about attributes is used to find records that meet
certain conditions. For example: Which ZIP Codes have an average household income of over
$40,000 per year? You use the Selection-Select by Condition command to select records and map features whose values meet a condition. You can choose this command from either a map or a dataview. Conditions can contain field names, math operators like +, -, *, and /, logical operators like <, >, <=, >=, and <>, and many different types of numeric and string functions. |
