查询错误！

CREATE TABLE 111_02DetermineCdeApproachable SELECT view_0501_011_01RecipientEgroup.recipient_id, SELECT Last(group_id) FROM view_0501_011_01RecipientEgroup AS group_id, if(group_id = 60 or group_id = 52 or group_id = 49 or group_id = 40 or group_id = 30,2,1) AS cde_approachable FROM tbl_111_01SelectMaxCreateDate INNER JOIN view_0501_011_01RecipientEgroup ON (tbl_111_01SelectMaxCreateDate.recipient_id = view_0501_011_01RecipientEgroup.recipient_id) AND (tbl_111_01SelectMaxCreateDate.max_create_date = view_0501_011_01RecipientEgroup.create_date) GROUP BY view_0501_011_01RecipientEgroup.recipient_id

你的错误   SQL语法;查看与MySQL服务器对应的手册   在第3行'SELECT Last(group_id) FROM view_0501_011_01RecipientEgroup AS group_id, if(grou'附近使用正确语法的版本

Answer 1

尝试使用此代码： -

if(group_id in (60, 49, 40) or groep_id in (52, 30, 2, 1) AS cde_approachable

如果group_id和groep_id不是你的错误。但如果它们相同，那么你必须尝试这样的事情： -

if(group_id in (60, 49, 40, 52, 30, 2, 1) AS cde_approachable

希望这可以帮到你。

Answer 2

试试这个：

CREATE TABLE 111_02DetermineCdeApproachable 
  SELECT v.recipient_id
       , Last( v.group_id )
       , if( group_id in ( 60, 52, 49, 40, 30 ), 2, 1 ) AS cde_approachable
  FROM tbl_111_01SelectMaxCreateDate t
       INNER JOIN view_0501_011_01RecipientEgroup v
               ON ( t.recipient_id    = v.recipient_id ) 
              AND ( t.max_create_date = v.create_date )
  GROUP BY v.recipient_id;

MySQL函数IF给出了错误
