Class: PG::BasicTypeMapForQueries::BinaryData
- Defined in:
- lib/rubypitaya/app-template/vendor/bundle/ruby/3.1.0/gems/pg-1.4.5/lib/pg/basic_type_map_for_queries.rb
Overview
Helper class for submission of binary strings into bytea columns.
Since PG::BasicTypeMapForQueries chooses the encoder to be used by the class of the submitted value, it’s necessary to send binary strings as BinaryData. That way they’re distinct from text strings. Please note however that PG::BasicTypeMapForResults delivers bytea columns as plain String with binary encoding.
conn.type_map_for_queries = PG::BasicTypeMapForQueries.new(conn)
conn.exec("CREATE TEMP TABLE test (data bytea)")
bd = PG::BasicTypeMapForQueries::BinaryData.new("ab\xff\0cd")
conn.exec_params("INSERT INTO test (data) VALUES ($1)", [bd])
