Question

我需要一些帮助。我试图从python中执行SQLLDR。我发现最好的方法是使用subprocess.call。使用params代替另一个函数，我在这段代码中复制了它。当我运行它时，我会按预期获得相应的字段。但是，该过程返回1，这是一个失败。我没有其他信息，无法找到可能存在的问题。

我已经验证了data.csv从BASH加载到我的表中，但是python没有。

def load_raw():
    DATA_FILE='data.csv'
    CONTROL_FILE='raw_table.ctl'
    LOG_FILE='logfile.log'
    BAD_FILE='badfile.log'
    DISCARD_FILE='discard.log'
    connect_string = os.environ['CONNECT_STRING']

    sqlldr_parms='rows=1000 readsize=50000 direct=true columnarrayrows=100 bindsize=500000 streamsize=500000 silent=(HEADER,FEEDBACK)'

    parms = {}
    parms['userid'] = connect_string
    parms['sqlldr'] = sqlldr_parms
    parms['data'] = DATA_FILE
    parms['control'] = CONTROL_FILE
    parms['log'] = LOG_FILE
    parms['bad'] = BAD_FILE
    parms['discard'] = DISCARD_FILE

    cmd = "userid=%(userid)s %(sqlldr)s data=%(data)s control=%(control)s log=%(log)s bad=%(bad)s discard=%(discard)s" % parms

    print "cmd is: %s" % cmd

    with open('/opt/app/workload/bfapi/bin/stdout.txt', 'wb') as out:
      process = call(cmd, shell=True, stdout=out, stderr=out)

    print process

cmd是：sqlldr userid = usr / pass rows = 1000 readsize = 50000 direct = true columnarrayrows = 100 bindsize = 500000 streamsize = 500000 silent =（HEADER，FEEDBACK）data = data.csv control = raw_table.ctl log = logfile.log bad = badfile.log discard = discard.log

进程返回1 不会创建log，bad和discard的日志文件

stdout.txt包含 / bin / sh：-c：第0行：意外令牌(' /bin/sh: -c: line 0:附近的语法错误sqlldr userid = usr / pass rows = 1000 readsize = 50000 direct = true columnarrayrows = 100 bindsize = 500000 streamsize = 500000 silent =（HEADER，FEEDBACK）data = data.csv control = raw_table.ctl log = logfile.log bad = badfile.log discard = discard.log＆＃39;

data.csv包含

id~name~createdby~createddate~modifiedby~modifieddate
6~mark~margaret~"19-OCT-16 01.03.23.966000 PM"~kyle~"21-OCT-16 03.11.22.256000 PM"
8~jill~margaret~"27-AUG-16 12.10.12.214000 PM"~kyle~"21-OCT-16 04.16.01.171000 PM"

raw_table.ctl

OPTIONS ( SKIP=1)
LOAD DATA
CHARACTERSET UTF8
INTO TABLE RAW_TABLE
FIELDS TERMINATED BY '~' OPTIONALLY ENCLOSED BY '"' TRAILING NULLCOLS
(ID,
NAME,
CREATED_BY,
CREATED_DATETIME TIMESTAMP,
MODIFIED_BY,
MODIFIED_DATETIME TIMESTAMP)

Answer 1

错误是由无声参数引起的。用单引号将其包装允许代码工作，如下所示：silent ='（HEADER，FEEDBACK）'

在python subprocess.call（）中使用sqlldr失败，但没有信息
