SQl语句收集

广告：

SELECT constraint_name
FROM information_schema.table_constraints
WHERE (constraint_type = 'primary key') AND (table_name = 'person')

得到约束名：aaaaaperson_PK

alter table tb
drop PK_tb --主键约束名
alter table person drop column sfz
exec sp_help '表名'就可以看到表结构

insert newtable select * from talbnemae 建表

mssql复制新表带数据 SELECT * INTO kfzlhao FROM kfzl
