Q. Why can't I access more than 4K of data in a TEXT field in SQL Server?
为什么TEXT字段不能存取大于4K的数据？
A. Probably because you haven't set the TEXTSIZE parameter. SET TEXTSIZE <n
Specifies the size, in bytes, of text data to be returned with a SELECT statement. If you specify a TEXTSIZE of 0, the size is reset to the default (4K). Setting TEXTSIZE affects the global variable @@TEXTSIZE.
The DB-Library variable DBTEXTLIMIT also limits the size of text data returned with a SELECT statement. If DBTEXTLIMIT is set to a smaller size than TEXTSIZE, only the amount specified by DBTEXTLIMIT is returned. For more information, see Microsoft SQL Server Programming DB-Library for C.
也许你没有设置TEXTSIZE参数
SET TEXTSIZE <n
用字节数指定SELECT语句返回的文本大小，如果指定大小为0，则设为默认值(4K)，设置TEXTSIZE参数影响全局变量@@TEXTSIZE
DB-Library变量DBTEXTLIMIT也限制SELECT语句返回的文本大小，如果DBTEXTLIMIT比TEXTSIZE小，则按DBTEXTLIMIT的设置返回数据，更多的内容请看“Microsoft SQL Server Programming DB-Library for C”。
