开始...每50行提交一次

Question

我有一个500,000行的sql脚本.

update users set region_id = 9814746 where id = 101 and region_id is null;
update users set region_id = 9814731 where id = 102 and region_id is null;
update users set region_id = 3470676 where id = 103 and region_id is null;
...
....

我需要能够生成一个脚本,每50行开始...提交.我该怎么做呢？我将在pg-admin中运行它.

谢谢,沙拉多夫

这可能是一个好的开始:
cat sql.file | perl -e 'i=0;print "begin;\n"; while(<>){print;i++;if(i % 50 == 0){print "end;\nbegin;\n";}}print "end\n";' > outputsql.file
