一个会话创建的临时表不能被其他会话访问。 创建临时表的关键字“temporary”可以缩写为“temp”。 PostgreSQL为了与其他数据库创建临时表的语句保持兼容,还没有“GLOBAL”和“LOCAL”关键字,但两个关键字没有用处。 三、示例 t开头的便是临时表。临时表会位于一个特殊的schema下面,此例是pg_temp_3 四、总结 禁...
按照标准,创建 TEMPORARY 表时可以指定 GLOBAL 或 LOCAL。但 PostgreSQL 不会区分它们;它只是忽略它们。 PostgreSQL 社区非常清楚所有问题,并且都有详细的记录。 参考:https://www.postgresql.org/docs/current/sql-createtable.html#SQL-CREATETABLE-COMPATIBILIT 它继续说道:“ SQL 标准还区分了全局临时表和本地临时...

Specifies the action taken on the global temporary table when a COMMIT operation is performed. DELETE ROWS: all rows of the table will be deleted if no holdable cursor is open on the table. PRESERVE ROWS: the rows of the table will be preserved after the COMMIT. ...
方法1, 使用商业数据库的版本 EDB, 他们支持GLOBAL TEMP 数据表 方法2, 使用POSTGRESQL 的无日志表来模拟所谓的GLOBAL 表 POSTGRESQL 的UNLOGGED TABLE, 这个功能是在POSTGRESQL 9.1 上开始的,主要的原因也是为了某些数据的写入的性能. 通过UNLOGGED TABLE 来解决的原因是,性能的问题, 我们都知道临时表是没有日志写入...

Hi Team, Kindly provide us the steps to create Global temporary table for Azure database for postgresql. Currently we are using postgresql 13. We are unable to create extension pgtt, getting error as could not open extension control file in postgresql.…
1. Create the structure of the global temporary table once, outside of pl/sql. 2. Utilize that table in your procedures. The contents of the table will be local to your session and will automatically disappear when you either log out or commit, depending on how the table is configured. ...
Review your code to see if you can use local temporary tables instead of global temporary tables. If not, refer to this post where we cover how to implement T-SQL global temporary table behavior in Babelfish for Aurora PostgreSQL using permanent table. This workaround involves...
