【问题描述】*：往临时表的LongVarchar字段，写入超过900长度的字符器，再查询，返回的结果提示无效的页错误。

重现步骤：
1 新建临时表
CREATE GLOBAL TEMPORARY TABLE test_EditData2
(
PK_ID int,
LongStr1 longvarchar
) ON COMMIT DELETE ROWS;

2 写入数据
declare @Str longvarchar;
begin
set @Str = 'declare @Table_ID varchar(50);
begin
with Temp as (select a.hw_RowNo, a.VALUE as Table_ID, b.VALUE as Field_ID from Tmp_GridData a join Tmp_GridData b
on a.hw_RowNo = b.hw_RowNo and a.Field_ID = ''Table_ID'' and b.Field_ID = ''Field_ID''),
TempA as (select a.hw_RowNo, b.DATA_TYPE, convert(varchar,b.Data_Length) as Data_Length,
convert(varchar, b.Data_Precision) as Data_Precision, convert(varchar, b.Data_Scale) as Data_Scale
from Temp a join All_Tab_Cols b on a.Table_ID = b.TABLE_NAME and a.Field_ID = b.COLUMN_NAME)
update Tmp_GridData a set a.VALUE = case
when b.DATA_TYPE in (''char'',''varchar'') then b.DATA_TYPE + ''('' + Data_Length + '')''
when ''DECIMAL'' then b.DATA_TYPE + ''('' + Data_Precision + '','' + Data_Scale + '')''
else b.DATA_TYPE end
from Tmp_GridData a join tempA b on a.hw_RowNo = b.hw_RowNo and a.Field12345678901234567890123456789011;
';

insert test_EditData2 (PK_ID, LongStr1) values(1, @Str);
select PK_ID, LongStr1 from test_EditData2;

select len(@Str);
end

3 查看LongStr1字段的数据，提示以下错误：

4 在用C#获取表返回数据时，也提示同样的错误
