For character fields, three special filtering characters are provided as pattern matching characters. All other characters reference a match of that specific character. These special filtering characters are:
Matches any string of characters
This character is a fuzzy match character. * can reference any number of characters as well as no characters.
For example:
* Matches everything
A* Matches data starting with A
*A Matches data ending with A (A, LA, FLORIDA, and so on)
*A* Matches A anywhere in the data (A, LA, OHARE, MAINE, and so on)
Matches any single character including a blank. If you are looking for an actual ?, you will match all characters, not just the ?
Matches a single non-blank character. If you are looking for an actual ^, you will match all non-blank characters, not just the ^.
For numeric fields, six special filtering characters are provided in addition to a number specification. These special filtering characters are:
All values
Specifies the number in thousands (1,000 times the number)
Specifies the number in millions, (1,000,000 times the number)
Separates two numbers to indicate a range of numbers
Suffixes the number to indicate all values greater than or equal to the number
Suffixes the number to indicate all values less than or equal to the number
