STARTS_WITH predicate
Supported by ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
STARTS_WITH predicates allow for finding strings by a common, fixed prefix.
Unlike the LIKE predicate (which can be used to emulate this), no wildcards are supported and the prefix must be matched exactly.
With jOOQ, the STARTS_WITH predicate can be created from any column expression as such:
STARTS_WITH(TITLE, 'abc')
BOOK.TITLE.startsWith("abc")
Dialect support
This example using jOOQ:
BOOK.TITLE.startsWith("abc")
Translates to the following dialect specific expressions:
ASE
BOOK.TITLE LIKE (str_replace(
str_replace(
str_replace('abc', '!', '!!'),
'%',
'!%'
),
'_',
'!_'
) || '%') ESCAPE '!'
