我正在使用sqlc库从 SQL 查询生成 go 代码。
我有一个像这样的子查询的查询：
COALESCE(SUM(invoice_payments.total), 0) AS paid,
并sqlc generate返回以下错误：
# package db
query.sql:101:1: relation "bigint" does not exist
我尝试使用 , 等进行操作::numeric，::int并且总是收到相同的结果
也试图像这样投长：
CAST(SUM(CAST( invoice_payments.total AS LONG)) AS LONG) AS paid,
SUM(invoice_payments.total::long)::long AS paid,
结果相同
带有完整示例的游乐场
