mongodb - mongo 的 mongoexport

Question

{代码...} 我在执行Mongoexport 老是报错 ，too many positional arguments: [{title:1}]] 但我单独去执行这个query的时候是有数据的，不知道为什么放在mongoexport里就报错。。。。。 麻烦知道的童鞋指导下

What operating system? This is mainly a problem of escaping special characters. There is probably something wrong with the system recognition of the braces you have here. Try changing it to the following:

mongoexport -h 192.168.1.8 -d video -c movie --query "{$and:[{site:{$size:1}},{title:1}]}" -f id,title --csv -o /log/mongo/1.csv
