So considering pg_query and pg_query_params don't return results on error, and that this would be an extremely handy thing to have, I just ended up writing my own functions wrapping the pg_send_* ones to work like the aforementionned two should. There's not a whole lot of code to ...

函数parse_analyze(处于analyze.c文件中)主要工作是处理语义分析,其会根据分析树生成一个对应的查询树,函数调用如下所示: query = parse_analyze(parsetree, query_string, paramTypes, numParams, queryEnv)。语义分析阶段会检查命令中是否有不符合语义规定的成分。例如,所使用的表、属性、过程函数等是否存在,聚集函...
同时通过pathman_config_params 来查看当前分区表的一些特性, 1 是否打开了父表,是否能插入数据 2 是否在插入数据超过了原有的设置后,会自动触发新建新的分区表 3 当插入超出分区范围的新数据时,使用SpawnPartitionsWorker在单独的事务中创建新分区。 这里注意不建议打开auto ,在插入数据的时候如果发现数据没有落在ra...
