从 Oracle 重写 SQL Server 查询

Question

我有查询，帮我为 SQL Server 重写它：

insert into swi (co, na, ci, ac, id, version, add) 
    select co, na, ci, acc, id, ?, address 
    from swi_tmp 
    where co||me not in (select co||me from swi)

我有，但还是不行

insert into swi (co, na, ci, ac, id, version, add) 
    select co, na, ci, acc, id, ?, address 
    from swi_tmp 
    where not exists (select 1 
                      from swi_tmp
                      where swi_tmp.co = swi.co and swi_tmp.na = swi.na)

Answer 1

NOT EXISTS 子查询中的FROM 子句使用源表而不是目标表。将NOT EXISTS子查询中的表名改为目标表名：

INSERT INTO swi (co, na, ci, ac, id, version, add) 
    SELECT co, na, ci, acc, id, ?, address 
    FROM swi_tmp 
    WHERE NOT EXISTS (SELECT 1 
                      FROM swi
                      WHERE
                          swi_tmp.co = swi.co
                          AND swi_tmp.na = swi.na
                     );
