该类函数的调用方式如下:SELECT* FROM some_func(); 它被放在FROM子句中作为数据源使用。...LOOP LOOP定义一个无条件的循环,直到由EXIT或者RETURN语句终止。可选的label可以由EXIT和 CONTINUE语句使用,用于在嵌套循环中声明应该应用于哪一层循环。 2)...CONTINUE 如果没有给出label,CONTINUE就会跳到最内层循环的...
当PG 启动后,Server 端会有进程监听指定端口(默认5432),这时候就可以有多个 psql(客户端进程)连进来。 当在 psql 中输入SELECT * FROM t;时,会发生以下几步: 1. psql 从输入读到SELECT * FROM t;这条语句; 2. psql 通过 libpq 将该语句发送到 Server 端; 3. Server 端执行后将查询结果发还给 psql;...
当前用例场景无操作返回。 对于其他操作符可能有配置,例如fix_opfuncids_walker->set_opfuncid会在pg_operator中取oprcode出来赋值。 pg_operator的oprcode表示当前操作符的处理函数的oid,关联pg_proc。 代码语言:javascript 复制 fix_opfuncids fix_opfuncids_walker expression_tree_walker_impl 传入 FuncExprcaseT...

Protein tertiary structure prediction is a fundamental problem in computational biology and identifying the most native-like model from a set of predicted models is a key sub-problem. Consensus methods work well when the redundant models in the set are t
