sqlserver2000中columns.precision问题
Create View dbo.vwSqlColumns
with encryption
as
select objects.name as ObjectName
, objects.type as ObjectType
, columns.name as ColumnName
, columns.column_id as colid
, columns.system_type_id as xtype
, columns.system_type_id as type
, (case when columns.max_length = -1 then 1073741823
when columns.system_type_id = 231 then columns.max_length/2
when columns.system_type_id = 99 then 1073741823
else columns.max_length
end
) as length
, columns.max_length
, columns.precision as prec
, cast(0 as bit) as cdefault
, cast(0 as bit) as isoutparam
以上sql在sqlserver2005中可以正确执行，但在sqlserver2000中出错：在关键字 'precision' 附近有语法错误。
这是什么问题？？？
[解决办法]
你用的是sys.columns吗，这个只有在2005才有，在2000是没有的，必须要修改，2000的只有syscolumns
[解决办法]
用这个试试：INFORMATION_SCHEMA.columns
[解决办法]
你改改
