重命名database脚本如下:
var source = "source";
var dest = "dest";
var colls = db.getSiblingDB(source).getCollectionNames();
for (var i = 0; i < colls.length; i++) {
var from = source + "." + colls[i];
var to = dest + "." + colls[i];
db.adminCommand({renameCollection: from, to: to});
}
测试：
> var source = "test";
> var dest = "test_new";
> var colls = db.getSiblingDB(source).getCollectionNames();
> for (var i = 0; i < colls.length; i++) {
... var from = source + "." + colls[i];
... var to = dest + "." + colls[i];
... db.adminCommand({renameCollection: from, to: to});
... }
{ "ok" : 1 }

> use test_new
switched to db test_new
> show tables
test
aaa
bbb
log
task
push_log
push_task
