Considere la siguiente consulta:columna "statement_date" es de tipo fecha, pero la expresión es de tipo entero
INSERT INTO statement_line_items
SELECT count(*)::integer as clicks, sum(amount_cents)::integer as amount_cents, imps.user_id, imps.created_at::date as statement_date
FROM impression_events imps
INNER JOIN transactions t ON t.event_id = imps.id
AND t.event_type = 'ImpressionEvent'
AND amount_cents >= 0
WHERE imps.created_at >= (now() - interval '8 days')::date
AND imps.created_at < (now() - interval '7 day')::date
AND imps.clicked = true
GROUP BY imps.user_id, imps.created_at::date;
Esto está regresando:
ERROR: column "statement_date" is of type date but expression is of type integer
LINE 2: ...icks, sum(amount_cents)::integer as amount_cents, imps.user_...

Mi estructura de la tabla de statement_line_items es:
"id"; "integer"
"user_id"; "integer"
"statement_date"; "date"
"description"; "character varying(255)"
"clicks"; "integer"
"amount_cents"; "integer"
"created_at"; "timestamp without time zone"
"updated_at"; "timestamp without time zone"
Ah, que estaba bajo la impresión de que se inserta en la misma columna llamada. Eso lo explica. –
Para mí, la instrucción de inserción que funcionó fue: 'INSERT INTO statement_line_items (col1, col2, ...) select data_for_col1, data_for_col2, ... from xyz'. Estoy usando Amazon Redshift. –
