Question

我正在尝试运行一个复杂的JPQL QUERY，它不会抛出异常并且工作很奇怪。

所以这是我的查询

SELECT b.pk.col1, b.pk.col2
  FROM table1 b
 WHERE     b.pk.col2 IN ('someString')
       AND b.pk.col3 IN (0, 1, 2)
       AND b.pk.sdate < :now
       AND b.edate > :now
       AND b.col4 = 1
       AND EXISTS
              (SELECT a.cmid
                 FROM table2 a
                WHERE a.col1 = 5 AND a.col2 = b.pk.col1)
       AND b.pk.col1 NOT IN
              (SELECT a.pk.col1
                 FROM table3 a
                WHERE CONCAT (a.pk.tagid, 'ayush') IN ('1ayush'))

由于某些原因，它会在最后一行引发错误。这是错误

异常数据：org.apache.openjpa.persistence.ArgumentException：遇到了＃34; b。 pk。 col1 NOT IN（从表3中选择一个.pk.col1 a CONCAT（a.pk.tagId，\＆＃39; ayush \＆＃39;）IN （＆＃34;字符249，但预计：[＆＃34;（＆＃34;，＆＃34;）＆＃34;，＆＃34; *＆＃34;，＆＃34; +＆＃ 34;，＆＃34;，＆＃34;，＆＃34; - ＆＃34;，＆＃34;。＆＃34;，＆＃34; /＆＃34;，＆＃34;：＆＃ 34;，＆＃34;＆lt;＆＃34;，＆＃34;＆lt; =＆＃34;，＆＃34;＆lt;＆gt;＆＃34;，＆＃34; =＆＃34;，＆＃34;＆gt;＆＃34;，＆＃34;＆gt; =＆＃34;，＆＃34;？＆＃34;，＆＃34; ABS＆＃34;，＆＃34; ALL＆＃34;，＆＃34; AND＆＃34;，＆＃34; ANY＆＃34;，＆＃34; AS＆＃34;，＆＃34; ASC＆＃34;，＆＃34; AVG＆＃34;，＆＃34; BETWEEN＆＃34;，＆＃34; BOTH＆＃34;，＆＃34; BY＆＃34;，＆＃34; CONCAT＆＃34;，＆＃34; COUNT＆＃34;，＆＃34; CURRENT_DATE＆＃34;，＆＃34; CURRENT_TIME＆＃34;，＆＃34; CURRENT_TIMESTAMP＆＃34;，＆＃34; DELETE＆＃34;，＆＃34; DESC＆＃34;，＆＃34; DISTINCT＆＃34;，＆＃34; EMPTY＆＃34;，＆＃34; ESCAPE＆＃34;，＆＃34; EXISTS＆＃34;，＆＃34; FETCH＆＃34;，＆＃34; FROM＆＃34;，＆＃34; GROUP＆＃34;，＆＃34; HAVING＆＃34;，＆＃34; IN＆＃34;，＆＃34; INNER＆＃34;，＆＃34; IS＆＃34;，＆＃34;加入＆＃34;，＆＃34; LEADING＆＃34;，＆＃34; LEFT＆＃34;，＆＃34; LENGTH＆＃34;，＆＃34; LIKE＆＃34;，＆＃34; LOCATE＆＃34;，＆＃34; LOWER＆＃34 ;, ＆＃34; MAX＆＃34;，＆＃34;会员＆＃34;，＆＃34; MIN＆＃34;，＆＃34; MOD＆＃34;，＆＃34; NEW＆＃34;，＆＃34; NOT＆＃34;，＆＃34; NULL＆＃34;，＆＃34; OBJECT＆＃34;，＆＃34; OF＆＃34;，＆＃34; OR＆＃34;，＆＃34; ORDER＆＃34;，＆＃34; OUTER＆＃34;，＆＃34; SELECT＆＃34;，＆＃34; SET＆＃34;，＆＃34; SIZE＆＃34;，＆＃34; SOME＆＃34;，＆＃34; SQRT＆＃ 34;，＆＃34; SUBSTRING＆＃34;，＆＃34; SUM＆＃34;，＆＃34; TRAILING＆＃34;，＆＃34; TRIM＆＃34;，＆＃34; UPDATE＆＃34;，＆＃ 34; UPPER＆＃34;，＆＃34; WHERE＆＃34; ,,,,,]。

为了清晰起见，我已将查询分成多行：

这是一行中的查询

    SELECT b.pk.col1, b.pk.col2
  FROM table1 b
 WHERE     b.pk.col2 IN ('someString')
       AND b.pk.col3 IN (0, 1, 2)
       AND b.pk.sdate < :now
       AND b.edate > :now
       AND b.col4 = 1
       AND EXISTS
              (SELECT a.cmid
                 FROM table2 a
                WHERE a.col1 = 5 AND a.col2 = b.pk.col1)
       AND b.pk.col1 NOT IN
              (SELECT a.pk.col1
                 FROM table3 a
                WHERE CONCAT (a.pk.tagid, 'ayush') IN ('1ayush'))

我忘了提及如果我尝试使用=而不是IN，则查询有效，但这是一个演示查询，我实际上必须使用List

编辑：这是我的新JPA QUERY，我给它一个Collection而不是一些硬编码值

SELECT b.pk.col1, b.pk.col2
  FROM table1 b
 WHERE     b.pk.col2 IN ('someString')
       AND b.pk.col3 IN (0, 1, 2)
       AND b.pk.sdate < :now
       AND b.edate > :now
       AND b.col4 = 1
       AND EXISTS
              (SELECT a.cmid
                 FROM table2 a
                WHERE a.col1 = 5 AND a.col2 = b.pk.col1)
       AND (b.pk.col1 NOT IN
               (SELECT a.pk.col1
                  FROM table3 a
                 WHERE CONCAT (a.pk.tagid, 'ayush') IN (:somelist)))

我仍然得到相同的例外

Answer 1

"xxx IN yyy"应为“{someValue} IN {someCollection}”。您没有右侧的集合，因此例外。如果您的查询现在确实在右侧有一个集合（它不在您的帖子中）并且您仍然获得异常，则发布实际的异常+堆栈跟踪。如果“xxx”和“yyy”应该相等，那么你使用“=”

与IN运算符一起使用时的JPA CONCATE抛出异常
