我有一个包含数据的巨大 CSV 文件，我正在尝试生成 mySQL 批量插入语句。

CSV 中的数据如下所示

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

我正在寻找创建一个批量插入，它将每 2 行组合成一个插入语句

具有所需输出的 ​​MySQL 语句

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);

与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);

使用更简洁的方法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);
