SQL语句该怎么写？

一个简单查询，已有6个参数，SQL脚本如下：

SELECT * FROM Table1 WITH (NOLOCK)

WHERE 1=1

${if(len(p_depot)=0,"","AND depot_code LIKE '"+p_depot+"%'")}

${if(len(p_region)=0,"","AND depot_region in ('"+p_region+"')")}

${if(len(p_province)=0,"","AND depot_province in ('"+p_province+"')")}

${if(len(p_city)=0,"","AND depot_city in ('"+p_city+"')")}

${if(len(p_deptyp_c)=0,"","AND depot_type in ('"+p_deptyp_c+"')")}

${if(len(p_Store)=0,"","AND depot_name in ('"+p_Store+"')")}

想增加一个复选框chkName，当这个复选框为选中的时候，执行查询条件

AND depot_name='AAA'，同时忽略其他6个参数的条件。如这个复选框没有被选中，继续保持上面6个参数的查询逻辑。这个语句该怎么写？

SELECT * FROM Table1 WITH (NOLOCK)

WHERE 1=1

${if(len(chkName)<>0,"","/*")}

AND depot_name='AAA'

${if(len(chkName)<>0,"","*/")}

${if(len(chkName)=0,"","/*")}

${if(len(p_depot)=0,"","AND depot_code LIKE '"+p_depot+"%'")}

${if(len(p_region)=0,"","AND depot_region in ('"+p_region+"')")}

${if(len(p_province)=0,"","AND depot_province in ('"+p_province+"')")}

${if(len(p_city)=0,"","AND depot_city in ('"+p_city+"')")}

${if(len(p_deptyp_c)=0,"","AND depot_type in ('"+p_deptyp_c+"')")}

${if(len(p_Store)=0,"","AND depot_name in ('"+p_Store+"')")}

${if(len(chkName)=0,"","*/")}

kenlewis(提问者) 您这个方法也很好，但是稍显麻烦一些。谢谢您的答案，对我也是有帮助的。

试试再加一个JS隐藏控件，cnkName控件是使用隐藏其他控件，保证其他控件满足第一个条件

kenlewis(提问者) 但这样做有一个风险，就是控件虽然被隐藏了，但是它的值是不是仍然可以读出来呢？如果在JS脚本里将控件值清空掉的话，又不符合我的题目要求了。

很困想睡觉回复 kenlewis(提问者) JS设置为不可用啊，有值不可用一样的效果。不用纠结这个了，这个思路太麻烦，1楼那个注释的思路目前来看是最优解。没想到注释还能这么用。
