MySQL已经走了与pymysql

Question

我在Python 3使用pymysql运行查询，像这样：

conn = 'con info here' 

cur = conn.cursor() 

cu.execute('sql goes here') 

查询去的线条之中：

load data 
local infile 'file path' 
ignore into table table_name 
fields terminated by '/t' 
optionally enclosed by '"' 
lines terminated by '\r\n' 
ignore 1 lines 

(@col1, 
@col2, 
@col3) 
set 
(col1indb = @col1, 
col2indb = @col2, 
col3indb = @col3) 

当我执行查询，我立即得到这个：

File "/opt/python3/lib/python3.4/site-packages/pymysql/cursors.py", line 296, in _query 
    conn.query(q) 
    File "/opt/python3/lib/python3.4/site-packages/pymysql/connections.py", line 781, in query 
    self._affected_rows = self._read_query_result(unbuffered=unbuffered) 
    File "/opt/python3/lib/python3.4/site-packages/pymysql/connections.py", line 942, in _read_query_result 
    result.read() 
    File "/opt/python3/lib/python3.4/site-packages/pymysql/connections.py", line 1143, in read 
    self._read_load_local_packet(first_packet) 
    File "/opt/python3/lib/python3.4/site-packages/pymysql/connections.py", line 1178, in _read_load_local_packet 
    sender.send_data() 
    File "/opt/python3/lib/python3.4/site-packages/pymysql/connections.py", line 1317, in send_data 
    self.connection._write_bytes(packet) 
    File "/opt/python3/lib/python3.4/site-packages/pymysql/connections.py", line 929, in _write_bytes 
    raise err.OperationalError(2006, "MySQL server has gone away (%r)" % (e,)) 
pymysql.err.OperationalError: (2006, "MySQL server has gone away (BrokenPipeError(32, 'Broken pipe'))") 

由于错误立即发生，我相信它不是超时。我运行的每一个其他查询都可以正常工作，即使是类似的加载查询。

我的问题是，什么在MySQL语法可以导致这个错误？

谢谢！

我有与pymysql，python3.5和远程MySQL服务器相同的问题。当我尝试插入带有巨大LONGTEXT字段的条目（例如man gcc 4次）时，它将回答相同的错误：MySQL server has gone away (BrokenPipeError(32, 'Broken pipe'))。当我使用简短的文本行时，它很好用，比如“HELLO WORLD”。
