当使用powerdesigner创建
数据库时要注意大小写。
注:以下脚本在oracle 10g,11g上正确执行
批量将表名变为大写
begin
for c in (select table_name tn from user_tables where table_name <> upper(table_name)) loop
begin
execute immediate 'alter table "'||c.tn||'" rename to '||c.tn;
exception
when others then
dbms_output.put_line(c.tn||'已存在');
end;
end loop;
end;
批量将空间内所有表的所有字段名变成大写
begin
for t in (select table_name tn from user_tables) loop
begin
for c in (select column_name cn from user_tab_columns where table_name=t.tn) loop
begin
execute immediate 'alter table "'||t.tn||'" rename column "'||c.cn||'" to '||c.cn;
exception
when others then
dbms_output.put_line(t.tn||'.'||c.cn||'已经存在');
end;
end loop;
end;
end loop;
end;
将用户空间的所有表名及所有字段变为大写
begin
for t in (select table_name tn from user_tables where table_name <> upper(table_name)) loop
begin
for c in (select column_name cn from user_tab_columns where table_name=t.tn) loop
begin
execute immediate 'alter table "'||t.tn||'" rename column "'||c.cn||'" to '||c.cn; www.2cto.com
exception
when others then
dbms_output.put_line(t.tn||'.'||c.cn||'已经存在');
end;
end loop;
execute immediate 'alter table "'||t.tn||'" rename to '||t.tn;
exception
when others then
dbms_output.put_line(t.tn||'已存在');
end;
end loop;
end;
