CLASS功能.替换传入的字符串成为SQL语句Where关键字后面的表达式:
词语搜索 [例如: 小明]
词组搜索
词组里面每一个词都将被检索
例如: 小强1 小名1 小强强 小小强
逻辑搜索
支持 And 和 Or 运算符.
例如: 小明 And 小强 And 小小强
复合条件:
例如:(小小明 Or 小明) And (小强 Or 小小强)
例如:(小小明 Or 小名) And 小小强
例如: ROOT1 And (广东人 Or 北京人)

替换好的字符串并不是完整的SQL语句.只是生成SQL语句的WHERE关键字后面的表达式.发送到ASP程序的时候.你可以在前面加上
"select id,标题,name,TableName from SearchAll where "
这样类似的SQL语句

Dim objROOT1
Set objROOT1 = new CreateQueryString
objROOT1.QueryString = strText '====传入要替换的字符串
objROOT1.strField = "要查询的字段名字" '===如果不设置.默认值是"(标题+文章)"

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
