    Takes a (schema, table) specification and returns the table's Catalyst schema.

    options

    - JDBC options that contains url, table and other information.

    returns

    A StructType giving the table's Catalyst schema.

    Exceptions thrown

    java.sql.SQLException if the table contains an unsupported type.
