SQL数据库备份解决方案
命令备份：BACKUP DATABASE test to DISK ='C/dfasd.bak'
1、查询出指定数据库中的所有表名称
Select TABLE_NAMEFROM 数据库名称.INFORMATION_SCHEMA.TABLESWhere TABLE_TYPE='BASE TABLE'
2、查询出指定表中的所有字段及精度
select a.name,
case a.precision
when 0 then
case a.is_ansi_padded
when 1 then
convert(nvarchar(15),b.name+'('+convert(nvarchar(10),a.max_length)+')')
when 0 then
b.name
end
else
case a.scale
when 0 then
b.name
else
b.name+'('+convert(nvarchar(10),a.precision)+','+convert(nvarchar(10),a.scale)+')'
end
end
as typelengthfrom sys.columnsa left join sys.typesb on a.system_type_id=b.system_type_idand a.user_type_id=b.user_type_idwhere a.object_id=(select object_id from sys.objectswhere name ='表名');
3、查询出SQL中数据库中所有表的定义
