SARG (search argument)

Sargable operators

include =, >, <, =>, <=, BETWEEN, and sometimes LIKE. Whether LIKE is sargable depends on the type and position of wildcards used.

Here are some SARG examples:
name = 'jones'
salary > 40000
60000 < salary
department = 'sales'
name = 'jones' AND salary > 100000
name LIKE 'dail%'


Here are some examples of nonsargable clauses:
ABS(price) < 4
name LIKE '%jon%'
name = 'jones' OR salary > 100000
