awk的创建CSV

批量的MySQL插入我有一个数据庞大的CSV文件，我试图生成MySQL的BULK INSERT语句。awk的创建CSV

数据呈现为以CSV

90927597|1356976813998|1356976814177|1356976817457|17756249959|17756249959|18663111085|17753220005|1090917|1775624995900|A

我希望创建一个批量插入，将每2行

MySQL的语句组合成单个插入语句与所需的输出如下

insert into data (90927597,1356976813998,1356976814177,1356976817457,17756249959,17756249959,18663111085,17753220005,1090917,1775624995900,A,90927599,1356976813098,1356976814797,1356976823738,12562175250,12562175250,12566502514,12565207040,1890362,1256217525000,A); 
insert into data (90927602,1356976813098,1356976814797,1356976823738,12562175250,12562175250,12566502514,12565207040,1890362,1256217525000,A, 90927603,1356976813098,1356976814797,1356976823738,12562175250,12562175250,12566502514,12565207040,1890362,1256217525000,A);

谢谢

Thanks Ed，我可以限制每个插入记录的数量吗？说每个插入100个记录？可能吗？ – Deano 2013-05-14 13:52:38

什么是记录？ “A”属于哪里？张贴一些典型的输入和预期的输出，因为当我们回答一个问题，然后你说：“哦，不，其实我想要做不同的事情”，然后，我们必须弄清楚，是通过阅读评论迭代什么是非常令人沮丧。 – 2013-05-14 14:07:31

Ed在所有应有的尊重，在我的问题的主体中提到的极限问题，我不想在得到回答后要求额外的。谢谢你的帮助寿！ – Deano 2013-05-14 14:15:24

随着awk：

$ awk 'BEGIN{printf "%s","insert into date ("}$NF{gsub(/\|/,",");printf "%s",$0}END{print ");"}' file 
insert into date (90927597,1356976813998,1356976814177,1356976817457,17756249959,17756249959,18663111085,17753220005,1090917,1775624995900,A90927599,1356976813098,1356976814797,1356976823738,12562175250,12562175250,12566502514,12565207040,1890362,1256217525000,A);

一种更简洁的方式使用tr：

$ echo "insert into date ($(tr -d '\n' < file));" | tr '|' ',' 
insert into date (90927597,1356976813998,1356976814177,1356976817457,17756249959,17756249959,18663111085,17753220005,1090917,1775624995900,A90927599,1356976813098,1356976814797,1356976823738,12562175250,12562175250,12566502514,12565207040,1890362,1256217525000,A);

谢谢你，你知道，如果有一种方法可以AWK打印选项限制在每条语句100线？ – Deano 2013-05-14 13:46:41

'print'每条语句打印一行，我不使用'print' ..请说明你的意思。 – 2013-05-14 13:48:01

现在，使用您的解决方案，我可以创建一个包含数千条记录的巨大单一批量插入语句的大文件。我可以拆分吗？成多个批量声明？每个可以说有100个记录？ – Deano 2013-05-14 13:50:43
