想要使用 $ALL_Total_Attach_ENB_data[0] 执行以下操作

  1. 从 $ALL_Total_Attach_ENB_data[0] 中存储的 CSV 数据中选择特定字符串。
  2. 用单引号括起来
  3. 将该数据作为输入传递给 mysql insert into 语句。

我已经完成了第 1 步，但不确定如何有效地完成第 2 步和第 3 步。可能一个衬垫会有所帮助。

实际数据 $ALL_Total_Attach_ENB_data[0]= ",ITEM,=,ENB,INTERVAL,=,HOUR,DURATION,=,2013-10-16,11:00,~,2013-10-16,12:00,ENB, TYPE,ATTEMPT,ACCEPT,COMB_ACPT,CTXT_RSP,SUCCESS,HSS_FAIL,ERR_IMEI,ERR_MS,ERR_SVC,GW_FAIL,GW_TO,ENB_FAIL,ENB_TO,UE_FAIL,ESM_FAIL,SM_FAIL,SM_TO,S1_REL,RSC_FULL,SYS_FLT,HSS_TO,AUC_FAIL,AUC_TO,EIR_FAIL EIR_TO,MS_TO,COLLIS,UNK_PLMN,APN_FAIL,ODB_BAR,DNS_FAIL,DNS_TO,CMP_TO,S1_REL1,ERR_ETC,CANCEL,DTCH,S_RATIO,C_RATIO,SET_TIME,AVG_CPS,PEAK_CPS,SS_RATIO,TOTAL,INIT,162797,150716,0,150134, 149450,0,1,0,0,4458,0,10,0,525,245,0,0,39,0,1,0,51,0,0,0,314,18,0,5950,0,1025,0,605, 2,2,0,80,92.58,91.80,583.20,45,48,97.25,COMB,17219,4601,0,4571,4560,0,0,0,0,1075,0,0,0,25, 27,7,0,2,0,0,0,243,0,0,0,103,1,300,10691,0,163,0,7,0,0,0,12,26.72,26.48,584.81,5,6,93.72,肌电图,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0.00,0。00,0.00,0,0,0.00";

而不是这个：

$val1=join(',' , @tmp[9,10,12,13,60 .. 103]);

您可以将该数组切片直接传递到execute()：

$rv = $sqlQuery->execute( @tmp[9,10,12,13,60 .. 103] ) 
    or die "can't execute the query: $sqlQuery->errstr"

不需要用引号将它们括起来。占位符将负责正确引用内容。
