来自主题: Statistics版 - 怎样用hash table做full join?
SAS hash can do inner join/left join easily.
just for learning purpose, full join is simply a left join + all records in
2nd table that can't be found in the 1st table. By this way, you need load
both table into hash (one full table + one table with key only); and you
need scan both tables once completely, so may not worth much of Hash.

要是为了服务周边居民,因此会员必须提供他们居住地的邮政编码。

Well, as I said, indexing large tables is not a good idea.
If an index cannot be all loaded into the memory,
then we are going to have O(log n) disk access,
compared with O(n) memory access.
This explains why data base servers require small index files and small
tables.
I can cite this link if you do not understand
why we normally do table scans for large tables.

现在组的manager说的。
俺的工作涉及把TSQL stored procedure code转成PL SQL, 有的 TSQL stored
procedure 有两三千行代码,好几个TEMP tables, 如果PL SQL 不用TEMP table,就只
能用 Associative Array or nested table, 处理数据,最后写到表里,中间过程不用
TEMP table,都在memory内。
Stroed procedure 的功能就是把几个millions records 级别的表join在一起,做一些
很简单判别,加减,再写进原来的表或不同的表。
这样的stored procedure有20多个,用linux cron job,每晚跑一次。
如果PL SQL stored procedure 用TEMP table, 转变从TSQL到PLSQL就很容易。不用的
话,大的stored procedure还是挺complex的。

On SQL Server 2008 R2, I need to add some columns into a table from another
table.
e.g.
Table1:
name value id
Jim 288 abf
Table 2:
name acct num rank
Jim 12 29 8
Jim 98 95 7
Jim 20 52 9
What I need:
name value id acct num rank acct num rank acct num rank
Jim 288 abf 12 29 8 98 95 7 20 52 9
The record numbers in table 2 may be variable.
Any help would be appreciate.

sql_stra = " CREATE TABLE [my_db].[dbo].[my_table] n"
sql_stra1 = "(n"
