Question

如何缩短以下查询以呈现相同的内容但使用较少的单词：

WHERE node.code＆lt;＆gt; ＆＃39;一个＆＃39; AND node.code＆lt;＆gt; ＆＃39; B＆＃39; AND node.code＆lt;＆gt; ＆＃39; C＆＃39; AND node.code＆lt;＆gt; ＆＃39; d＆＃39; AND node.code＆lt;＆gt; ＆＃39; E＆＃39; AND node.code＆lt;＆gt; ＆＃39; F＆＃39;

Answer 1

您可以使用您不想要的值的集合，并执行成员资格检查：

WITH ['a', 'b', 'c', 'd', 'e', 'f'] as excludedCodes
// though it's better to pass these in as a list parameter if you can
... // perform your matches and such
WHERE NOT node.code in excludedCodes
...
