环境介绍

在某些场景(分区表子表)需要批量创建表空间,给不同的表使用,以下代码是批量创建表空间的SQL语句;

1 批量创建表空间SQL

--创建 24个数据表空间,每个表空间有3个数据文件,一个数据文件初始化为128M,每次扩展1024M,最大扩展到 409600M

DECLARE
    TBS_NAME VARCHAR :='TBS_DATA_';		--数据表空间名称
    --TBS_NAME VARCHAR :='TBS_INDEX_';	--索引表空间名称

    TBS_COUNT        INT :=24;	--表空间数量
    TBS_FILE_COUNT   INT :=3;	--表空间数据文件数量
    TBS_FILE_F       INT;
    
    TBS_EXTENT_BEGIN VARCHAR;
    TBS_EXTENT_TEMP  VARCHAR;
    TBS_EXTENT_TEMP2 VARCHAR;
    TBS_EXTENT_END   VARCHAR;
    TBS_EXTENT_ALL   VARCHAR;
BEGIN
    FOR I IN 1..TBS_COUNT 
    LOOP
        TBS_EXTENT_BEGIN :='create tablespace "'||TBS_NAME||I||'" datafile '''||TBS_NAME||I||'_FILE_1.DBF'' size 128 autoextend on next 1024 maxsize 409600';
        TBS_EXTENT_TEMP  :='';
        FOR TBS_FILE_F IN 2..TBS_FILE_COUNT 
        LOOP
            TBS_EXTENT_TEMP2    := ','''||TBS_NAME||I||'_FILE_'||TBS_FILE_F||'.DBF'' size 128 autoextend on next 1024 maxsize 409600';
            TBS_EXTENT_TEMP := TBS_EXTENT_TEMP||TBS_EXTENT_TEMP2;
        END LOOP;
        TBS_EXTENT_END := ' CACHE = NORMAL;';
        TBS_EXTENT_ALL :=TBS_EXTENT_BEGIN||TBS_EXTENT_TEMP||TBS_EXTENT_END;
        PRINT (TBS_EXTENT_ALL);
        EXECUTE IMMEDIATE TBS_EXTENT_ALL;
    END LOOP;
END;
-- 生成的创建表空间 SQL
