CAN_JSON_PARSE 及其关联函数将 JSON 值解析为 SUPER,Amazon Redshift 解析 SUPER 的效率比 VARCHAR 更高。 我们建议您使用CAN_JSON_PARSE 函数验证您的 JSON 字符串,而不是使用 IS_VALID_JSON。 IS_VALID_JSON 函数用于验证 JSON 字符串。如果字符串是格式正确的 JSON 字符串,则该函数返回布尔值true;如果字符...

由于json.isvalid不存在,我们需要使用其他方法来验证JSON的有效性。在Python中,可以通过尝试解析JSON字符串来验证其有效性。如果解析成功,则说明JSON是有效的;如果解析失败,则抛出异常,说明JSON是无效的。 提供替代方法或函数的使用示例和说明: 使用json.loads()方法来验证JSON字符串的有效性。如果JSON字符串格式正确...
