Copy Statement

We support "COPY relation FROM file", "COPY relation TO file", and "COPY (query) TO file". In any given CopyStmt, exactly one of "relation" and "query" must be nonNULL.

Fields

type_: NodeTag

relation: *mut RangeVar

query: *mut Node

the relation to copy

attlist: *mut List

the query (SELECT or DML statement with RETURNING) to copy, as a raw parse tree

is_from: bool

List of column names (as Strings), or NIL for all columns

is_program: bool

TO or FROM

filename: *mut c_char

is 'filename' a program to popen?

options: *mut List

filename, or NULL for STDIN/STDOUT

whereClause: *mut Node

List of DefElem nodes
