SELECT * FROM myTable </cfquery> 上述代码中,myQuery是查询结果的名称,myDataSource是在ColdFusion中配置的MySQL数据源名称,myTable是要查询的表名。 接下来,可以使用CFOutput标签来动态输出查询结果。默认情况下,CFOutput标签会输出列名和对应的值。如果不希望输出列名,可以使用query属性的columnlist参数,并将其设置...

将Query 的 Result 转换为 List 代码语言:javascript 复制 valueList(column, [delimiter]) ListLen 获取List 的长度, 在 Loop 的时候可能会用到 ListContains 代码语言:javascript 复制 ListContains(list, substring [, delimiters, includeEmptyValues ]) ##ListContains(aList, "wo")# Description Determine...
