我正在尝试创建一个临时表空间,其大小是'TEMP'表空间的一半。
类似于:
create temporary tablespace Temptest
TempFile 'somepath'
size ?M;
在哪里? =
select bytes/2/1024/1024
from dba_temp_files
where tablespace_name='TEMP';
答案 0 :(得分:1)
您可以编写使用动态SQL的PL / SQL块。像
这样的东西DECLARE
l_current_temp_size_mb NUMBER;
l_sql_stmt VARCHAR2(1000);
BEGIN
SELECT SUM(bytes)/1024/1024
INTO l_current_temp_size
FROM dba_temp_files
WHERE tablespace_name = 'TEMP';
l_sql_stmt :=
'CREATE TEMPORARY TABLESPACE tempTest TEMPFILE <<somepath>> size ' ||
to_char( l_current_temp_size_mb / 2 ) ||
' M';
-- Print out the SQL statement or write it to a table so that if there is an error,
-- you know what SQL statement was generated and can debug it.
dbms_output.put_line( l_sql_stmt );
EXECUTE IMMEDIATE l_sql_stmt;
END;
