table.csv

现象是dolphindb这边的count居然会自己缩小。比如说运行一次，所有的行数一样了，过几分钟在运行一次，发现ddb这边的表的行数变小了，于是又出发了导入。

求解答！谢谢。如需要，可以提供mysql表的csv文件

代码如下：

conn = mysql::connect(localhost, 3306, `xxx, "xxx", `db_name)

dbPath="dfs://db_name"

yearRange=date(2005.01M + 12*0..22)

db=database(dbPath,RANGE,yearRange)

a = mysql::load(conn, "select count(*) from `" + i + "`") // i代表其中一个表，为了容易看明白，把循环去掉了

if(existsTable(dbPath, i)){

    b = select count(*) from loadTable(dbPath, i)

}else{

        b = {"count": 0}

}

rows_to_import =  a['count(*)'][0] - b['count'][0]

if (a['count(*)'][0] > 0 and rows_to_import > 0){

    print "         " + i + " in mysql's row count is " + a['count(*)'][0] + " in ddb's is " + b['count'][0]

    print 'importing ' + i + ' with ' + rows_to_import + ' rows'

    mysql::loadEx(conn, db, i, `timestamp, i,, b['count'][0], rows_to_import)

}else{

    print 'skiping ' + i

}
