ORACLE純SQL實現多行合并一行項目中遇到一個需求,需要將多行合并為一行。表結構如下:NAME Null Type------------------------ --------- -----N_SEC_CODE NOT NULL CHAR(6)C_RESEARCHER_CODE NOT NULL
---------------------------------------insert into table-name select ...---------------------------------------insert into table-name values(coL-values, ... default)---------------------------------------CREATE TABLE raises (emp_id NUMBER, sal
TO_DATE格式 Day: dd number 12 dy abbreviated fri day spelled out friday ddspth spelled out, ordinal twelfth Month: mm number 03 mon abbreviated mar month spelled out march Year: yy

create or replace procedure t_ps_TryCalculate(v_date in varchar2)AS/*每月績效校正,根據參數判斷員工業績是否通過。參數:v_date 績效年月*/--定義錯誤變數some_kinds_of_err EXCEPTION; -- Exception to indicate an error conditionv_ErrorCode NUMBER; -- Variable to hold the error message

一、求幾何對象的長度格式: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->SDO_GEOM.SDO_LENGTH(geom IN MDSYS.SDO_GEOMETRY,dim IN MDSYS.SDO_DIM_ARRAY[,unit IN VARCHAR2]) RETURN NUMBER;或 Code highlighting produced
遇到非常長的SQL語句無法執行該怎麼辦呢?看下面的解決辦法:/*-----------------------------------|執行長SQL,如參數、值非常大----------------------------------------*/CREATE OR REPLACE PROCEDURE SP_EXECUTELOG(SSQL IN VARCHAR2, SLONG IN CLOB) ISBEGIN EXECUTE IMMEDIATE SSQL USING SLONG;
