在实际的使用中使用:Select Function2(ID) from Dual;,但是老报以下错误: ORA-06502: PL/SQL: numeric or value error: character string buffer too smallORA-06512: at "TROY.ONTRAC_QRS_PKG", line 760ORA-14551: cannot perform a DML operation inside a query ORA-06512: at "TROY.COMMON_SYSTEMLOG...
ORA-14551:cannot perform a DML operation inside a query 执行SELECT前,系统会检查语句中否存在对表的INSERT,UPDATE,DELETE操作,默认是禁止此类操作的。可对函数做适当调整,加上PRAGMA AUTONOMOUS_TRANSACTION即可解决问题。如: FUNCTION test_function(p_f1 IN VARCHAR2) RETURN VARCHAR2 IS PRAGMA AUTONOMOUS_TRANSAC...
and performance improvement. Specifically, we present critical-path-DML approaches that analyze the design's critical paths and selectively allow for their operation in the fast, dynamic mode; by contrast, the energy reduction is achieved by static operation of the non-critical path of the system....
If a single key-value pair is being added into a cache then, eventually, an INSERT statement will be converted into a cache.putIfAbsent(…) operation. In other cases, when multiple key-value pairs are inserted, the DML engine creates an EntryProcessor for each pair and uses cache.invoke...

这里的this.plan就是SingleTableOperation,handler是PolarDB-X的CN与DN间交互的MyJdbcHandler,可以认为是执行物理计划的handler,会根据plan生成真正的物理SQL,下发到DN执行。 由于这条SQL较为简单,CN不需要过多处理,再举一例Insert语句:insert into sbtest(k) values(101),(102); 经过优化器后,该语句的执行计划是...

The bitwise operation is applied to tensor data in its native encoding. Therefore, the tensor data type is ignored except for determining the width of each element. This operator supports in-place execution, meaning that OutputTensor is permitted to alias one of the input tens...
