			This function use the transaction sqlca twice.

=============================================================

通用查询,支持多表关联、带参数

只需要传递一个参数datawindow,剩下的一切交给这个函数去完成,看看她功能的强大吧
使用此功能调用方法:
gf_set_query(datawindow add_dw)
ad_dw		:	被查询数据窗

query.pbl	:	可带参数查询,必须在被查询数据窗上定义一个事件 ue_retrieve,
			来执行 retrieve 函数(带参数或不带参数)
			本功能使用sqlca事务对象两次

规则		:	被查询列必须是可视的,并且该数据窗必须有一个以 '列名_t' 命名的text控件

对象		:
dw_jzh_query	:	查询数据窗
gf_add_where	:	为数据窗添加 where 语句
gf_set_query	:	查询函数
w_jzh_query	:	查询窗口

如果你想保存上次的查询条件,可以传递一个窗口,你可以自己来做,也可以找我帮忙.
