我们有一个非常复杂的查询，我们使用eval（）函数来评估一些数据。OrientDB：AND运算符在eval（）函数内
但似乎AND运算符不正确处理eval（）内。
例如：
if(eval('#20:34 IN out[@class='attempts'][email protected] AND \'b\' IN out[@class='attempts'].choice'), true, false) as attempt_b
在这个例子中，我们期待与#20:34，并与“B”的“选择”属性，是要回报的@rid只得到数据为真
“out”字段有$ current。@ rid我们的SELECT查询。
这是示例数据：
out ------ in ---- choices
14:3 ---- 20:34 ------ b
14:4 ---- 20:34 ------ a
14:7 ---- 20:34 ------ c
14:8 ---- 20:34 ------ d
例：if(eval('#20:34 IN out[@class='attempts'][email protected] AND \'" + choice + "\' IN out[@class='attempts'].choice'), true, false) as attempt_choice
1）[email protected] = #14:3 and choice is 'a'
Return Output: true
Expected output: false (since there is no #20:34 with a choice of "A" in [email protected] which is #14:3)
2.）[email protected] = #14:3 and choice is 'b'
Return Output: true
Expected output: true
3）[email protected] = #14:3 and choice is 'c'
Return Output: true
Expected output: false (since there is no #20:34 with a choice of "c" in [email protected] which is #14:3)
4）[email protected] = #14:3 and choice is 'd'
Return Output: true
Expected output: false (since there is no #20:34 with a choice of "d" in [email protected] which is #14:3)`
我不知道这是否只是我们的查询问题或orientdb。如果有人能够引导我达到我们想要实现的目标，这将是一个很大的帮助。
