-bash：意外令牌'（'附近的语法错误

Question

我正在尝试在OSX的终端中运行以下查询。 它不断返回：

-bash: syntax error near unexpected token `('

我确定我会忽略一些非常愚蠢的东西。 如果有人能指出我正确的方向，我将不胜感激。 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而不是使用' ，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

或者按照@bhesh的指定，您可以分隔bash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
