Question

我在python 3中使用pymysql运行查询，类似于：

conn = 'con info here'

cur = conn.cursor()

cu.execute('sql goes here')

该查询属于以下行：

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)

当我执行查询时，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，我确信它不是超时。我运行的每一个其他查询都可以正常工作，甚至类似的加载查询。

我的问题是，MySQL语法中的哪些内容会导致此错误？

谢谢！

我对pymysql，python3.5和远程MySQL服务器有同样的问题。当我尝试插入一个包含巨大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'))。当我只使用短文本行时，它很有效，例如＆＃34; HELLO WORLD＆＃34;。

MySQL已经与pymysql一起消失了
