# Sequel::Postgres::HStoreOp

The HStoreOp class is a simple container for a single object that defines methods that yield Sequel expression objects representing PostgreSQL hstore operators and functions.

In the method documentation examples, assume that:

    hstore_op = :hstore.hstore

### Constants

CONCAT
CONTAINED_BY
CONTAINS
CONTAIN_ALL
CONTAIN_ANY
HAS_KEY
LOOKUP
RECORD_SET

### Public Instance Methods

Delete entries from an hstore using the subtraction operator:

    hstore_op - 'a' # (hstore - 'a')

    # File lib/sequel/extensions/pg_hstore_ops.rb, line 91
    def -(other)
      other = if other.is_a?(String) && !other.is_a?(Sequel::LiteralString)

      end
      HStoreOp.new(super)

Lookup the value for the given key in an hstore:

    hstore_op['a'] # (hstore -> 'a')

    # File lib/sequel/extensions/pg_hstore_ops.rb, line 103
    def [](key)
