-- Session A creates a global temp table ##test in Azure SQL Database testdb1 -- and adds 1 row CREATE TABLE ##test ( a int, b int); INSERT INTO ##test values (1,1); -- Session B connects to Azure SQL Database testdb1 -- and can access table ##test created by session A...
So if I create the table in my session, Bob in the office next door will also see them. What I am looking for is somewhere in the middle, so I can create the table within a stored procedure and have that table be available to my session even after the stored proc exits. The neares...

CREATE GLOBAL TEMPORARY TABLE ステートメントは、現行のサーバー上に一時表の記述を作成します。作成済み一時表を参照する各セッションは、それぞれのセッション内で挿入された行のみを取得します。セッションが終了すると、そのセッションに関連する行は表から削除されま
global temporary tabl global temporary table并发 如果所处理的数据会一直保留在应用的逻辑工作单元中,可以考虑使用全局临时表(global temporary table,GTT),而不要反复建立或物化数据。如果在程序执行期间多次获取或物化同样的数据,可以把这些数据在一个GTT中加载一次,然后在代码的其他地方引用这个表。
clickhouse的global in/join 和普通的in/join的区别 总结转载 https://clickhouse.tech/docs/zh/sql-reference/operators/in/#select-distributed-subqueries SELECT uniq(UserID) FROM distributed_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM distributed_table WHERE CounterID = 34)...
SELECT uniq(UserID) FROM local_table WHERE CounterID = 101500 AND UserID IN (SELECT UserID FROM distributed_table WHERE CounterID = 34) 这种情况ck同样会对SQL进行重写,但此时不是将分布式表转换为本地表,而是直接分发这个SQL语句到存在local_table表的所有节点,在子查询是分布式表的情况下,每个接收到分...
A given query is transformed into a transformed query that references a global temporary table. Specifically, the given query contains a join between a given table and one or more other tables referenced by constraints (e.g. predicates). References to one or more of the constrained tables are...
an Oracle database, you create a static table definition. The temporary table is a persistent object described in the data dictionary, but appears empty until your session inserts data into the table. You create a temporary table for the database itself, not for every PL/SQL stored procedure...
The reason is that "Query 4" refers to ##tmpTest table not with a single T-SQL command. It refers to it in each iteration in the while loop. So, when "Query 1" is closed (##tmpTest dropped), SQL Server waits until "Query 4" completes its latest T-SQL statement which refers to...
