Question

我正在尝试在OSX上的Terminal中运行下面的查询。它一直在回归：

-bash: syntax error near unexpected token `('

我确定我忽视了一些非常愚蠢的事情。如果有人能指出我正确的方向，我会很感激。该命令包括要执行的程序的SQL查询：

java -Xmx16g -cp .:lib/* edu.cuny.util.VectorToInstancesConverter train HandednessJ48 “SELECT * FROM collection1.Session1 WHERE Subj_Id!=402 and Subj_Id not in ( select Subj_id from collection1.Session2) AND Subj_Id IN ( SELECT Subj_Id FROM collection1.userdata WHERE 'DominantHand' = 'l' OR 'DominantHand' = 'r')” 12 J48

Answer 1

问题是，当您使用" bash尝试评估其中的任何内容时，您应该使用'，请尝试以下操作：

java -Xmx16g -cp .:lib/* edu.cuny.util.VectorToInstancesConverter train 
HandednessJ48 'SELECT * FROM collection1.Session1 WHERE Subj_Id!=402 
and Subj_Id not in ( select Subj_id from collection1.Session2) AND 
Subj_Id IN ( SELECT Subj_Id FROM collection1.userdata WHERE 
'DominantHand' = 'l' OR 'DominantHand' = 'r')' 12 J48

或@bhesh已指定您可以分隔bash将尝试评估的字符：

java -Xmx16g -cp .:lib/* edu.cuny.util.VectorToInstancesConverter train 
HandednessJ48 "SELECT * FROM collection1.Session1 WHERE Subj_Id!=402 
and Subj_Id not in \( select Subj_id from collection1.Session2\) AND 
Subj_Id IN \( SELECT Subj_Id FROM collection1.userdata WHERE 
'DominantHand' = 'l' OR 'DominantHand' = 'r'\)" 12 J48
