Question

我是SQLDeveloper的新手。请帮我纠正合并语法。我想将act_sl tavle中的数据合并到act_sls_0表中我在From Clause中使用2个连接。但我得到错误：错误（13,13）：PL / SQL：ORA-00969：缺少ON关键字错误（4,1）：PL / SQL：忽略SQL语句

merge into act_sls_0 using(

Answer 1

合并声明的格式为：

merge into <target_table> tgt
  using <table_name or subquery> src
  on (<join conditions between the target and source datasets>)
when matched then
  update set ...
when not matched then 
  insert (...)
  values (...);

除了你的源子查询不正确之外（t1和t2所在的位置有错误;括号太多，不正确地尝试别名等等），当你在子查询中加入条件时，你＆＃39 ;完全错过了合并本身的ON子句。

您需要定义与源子查询返回到目标表的数据匹配的连接条件。

Now the error is : src.ga - Invalid Identifier

虽然我在Trg表和src表中有ga表。

merge into act_sls_0 trg using( select * from 
(select a_0.asp, gadim.uic as ga, pmm_styleid, week, colorcode ,  sizecode,      storenum, units_asly,retail_asly,

        join a_0 on ( w.externalkey between startweek and endweek)
        join dimension strdim on strdim.externalkey = (case when length(storenum) <= 4 then RPAD('STR-', 8 - length(storenum), '0') else 'STR-' END) || storenum
        join store_info_0 str on store = strdim.uic
        join dimension gadim on gadim.externalkey = decode(store_type, 'RETAIL', 'GA-01', 'ECOM', 'GA-02', '')
        where trendweeks < 6)t1
        join(select distinct asp, product, ga, color, sstyl_shade, pmm_styleid  from aplc_1 aplc

        and t1.ga = t2.ga))src
        on (trg.asp = src.asp and trg.pmm_styleid = src.pmm_styleid and trg.colorcode = src.colorcode and trg.ga = src.ga)

提交;

使用子连接将源表合并到目标表中
