【问题描述】：

我有一个原生查询

        "SELECT *, point(?2, ?1) <@> point(lng,lat) as distance FROM workers " +
                " LEFT JOIN availabilities on availabilities.worker_id = workers.id " +
                " WHERE workers.category_id = ?3 " +
                " WHERE worker_availability.time = ?4 ORDER BY distance ASC",
        nativeQuery = true
    )

我不断收到的错误是

org.postgresql.util.PSQLException: ERROR: syntax error at or near "WHERE"

【问题讨论】：

SELECT 语句中只能有一个 WHERE 子句。

【参考方案1】：

你写了 2 次“WHERE”。你必须改变这个：

" WHERE worker_availability.time = ?4 ORDER BY distance ASC",

到这里：

" AND worker_availability.time = ?4 ORDER BY distance ASC",
