Examples of org.apache.phoenix.expression.LikeExpression

org.apache.phoenix.expression.LikeExpression
Implementation for LIKE operation where the first child expression is the string and the second is the pattern. The pattern supports '_' character for single character wildcard match and '%' for zero or more character match. where these characters may be escaped by preceding them with a '\'. Example: foo LIKE 'ab%' will match a row in which foo starts with 'ab' @since 0.1
