MySQL已經走了與pymysql

Question

我在Python 3使用pymysql運行查詢，像這樣：

conn = 'con info here' 

cur = conn.cursor() 

cu.execute('sql goes here') 

查詢去的線條之中：

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) 

當我執行查詢，我立即得到這個：

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'))") 

由於錯誤立即發生，我相信它不是超時。我運行的每一個其他查詢都可以正常工作，即使是類似的加載查詢。

我的問題是，什麼在MySQL語法可以導致這個錯誤？

謝謝！

我有與pymysql，python3.5和遠程MySQL服務器相同的問題。當我嘗試插入帶有巨大LONGTEXT字段的條目（例如man gcc 4次）時，它將回答相同的錯誤：MySQL server has gone away (BrokenPipeError(32, 'Broken pipe'))。當我使用簡短的文本行時，它很好用，比如「HELLO WORLD」。
