对此查询不可能，因此必须编写自己的存储过程.

例子
创建名称为tlbTextData的表

It is not possible with the query for this u have to write your own store procedure.

Example
Create Table of name tlbTextData

create table tlbTextData (fldTextKey varchar(10), fldTextVal varchar(10))
insert into tlbTextData values('One','1')
insert into tlbTextData values('Two','2')
insert into tlbTextData values('Three','3')
insert into tlbTextData values('Four','4')
insert into tlbTextData values('Five','5')
