如何使用DBMS_STATS.set_table_prefs将具有相同所有者的多个表的Incemental设置为true? [英] How do you set Incemental to true for multiple tables with the same owner using DBMS_STATS.set_table_prefs?

问题描述

我的oracle数据库中大约有40-50个表已分区.我想使用DBMS_STATS.set_table_prefs将所有分区表的增量"设置为true.有人可以帮我吗?

以下是查询:

SELECT DISTINCT(表名)，partitioning_type，subpartitioning_type，OWNER 来自all_part_tables 所有者='用户' ORDER BY table_name ASC;

解决方案

此PL/SQL块(基于您在另一个问题中的评论)循环遍历用户的分区表，并将其增量首选项设置为true.

begin
    for a in
    (
        select distinct (table_name), owner
        from all_part_tables
        where owner = 'SOME_USER_NAME'
            --Ignore objects in the recycle bin.
            --There are other "tables" that may need to be ignored, 
            --such as external tables, storage tables, etc.
            and table_name not like 'BIN$%'
        order by table_name
    ) loop
        dbms_stats.set_table_prefs(a.owner, a.table_name, 'incremental', 'true');
    end loop;
end;

I have around 40-50 tables in my oracle database that are partitioned. Using DBMS_STATS.set_table_prefs, I want to set "Incremental" to true for all of my partitioned tables. Can anyone help me with this?

Below is the query:

SELECT DISTINCT (table_name), partitioning_type, subpartitioning_type, OWNER FROM all_part_tables WHERE OWNER = 'user' ORDER BY table_name ASC ;

解决方案

This PL/SQL block (which is based on your comment in another question) loops through partitioned tables for a user and sets their incremental preference to true.

begin
    for a in
    (
        select distinct (table_name), owner
        from all_part_tables
        where owner = 'SOME_USER_NAME'
            --Ignore objects in the recycle bin.
            --There are other "tables" that may need to be ignored, 
            --such as external tables, storage tables, etc.
            and table_name not like 'BIN$%'
        order by table_name
    ) loop
        dbms_stats.set_table_prefs(a.owner, a.table_name, 'incremental', 'true');
    end loop;
end;
