Carlos Soublette #8-35Ĭarrera 52 con Ave. LIKE The LIKE command is used in a WHERE clause to search for a specified pattern in a column. PostgreSQL also provides some operators that act like the LIKE, NOT LIKE, ILIKE and NOT. To match a sequence anywhere within a string, the pattern must start and end with a percent sign. If you use the LIKE operator instead, the query will not return any row. LIKE pattern matching always covers the entire string. LIKE, ILIKE, and RLIKE all perform similar operations however, RLIKE uses POSIX EXE (Extended Regular Expression) syntax instead of the SQL pattern syntax used by LIKE and ILIKE. Unlike the LIKE function, string matching is case-insensitive.

ILIKE Allows matching of strings based on comparison with a pattern.
