Abstract

The string pattern search operator LIKE of SQL has been developed based on English such that each search pattern of English of the operator works for each character in the alphabet of English. For finding Korean, search patterns of the operator can be expressed by both the alphabet and syllables of Korean. As a phonetic symbol, each syllable of Korean is composed either of a leading sound and a medial sound or of a leading sound, a medial sound, and a trailing sound. By utilizing that characteristic of Korean syllables, in addition to the traditional complete-syllable based search pattern of Korean, this paper proposes an incomplete-syllable based search pattern of Korean, as a pattern of the operator LIKE, to find Korean syllables having specific leading sounds, specific medial sounds, or both specific leading sounds and medial sounds. Formulating predicates that are equivalent with the incomplete-syllable based search pattern of Korean by way of existing SQL expressions is cumbersome and might cause the portability problem of applications depending on the underlying character set of the DBMS.
