AdvancedMeta

sealed trait AdvancedMeta[A] extends Meta[A]

Meta for "advanced" JDBC types as defined by the specification. These include Array, JavaObject, Struct, and other types that require driver, schema, or vendor-specific knowledge and are unlikely to be portable between vendors (or indeed between applications). These mappings require (in addition to matching JDBC types) matching driver, schema, or vendor-specific data types, sadly given as Strings in JDBC.

  3. abstract def scalaType: String

    Name of the Scala type, for diagnostic purposes.

    Name of the Scala type, for diagnostic purposes. Smart constructors require a TypeTag to guarantee this value is correct.

  4. abstract val schemaTypes: NonEmptyList[String]

    List of schema types to which values of type A can be written and from which they can be read.

    List of schema types to which values of type A can be written and from which they can be read. Databases will often have several names for the same type, and the JDBC driver may report an alias that doesn't appear in the schema or indeed in the database documentation. This field is therefore a list.
