过长的sql语句还是建议用NamedQuery自己来写,因为如果你用map[string]interface{}来描述太长的sql语句,你作为用户几乎不太可能能确信gendry最终帮你生成的sql语句是什么。NamedQuery可以在任何时候使用,NamedQuery("select * from table_foo where age > {{age}} and MATCH(col_bar) AGAINST({{keyword}} IN BOOLEAN MODE)", map[string]interface{}{"age":5,"keyword":"xxx"})
这种并不比map[string]interface{}写起来更复杂吧?
我认为map[string]interface{}适合用来描述简单的、可以用and连接起来的sql语句,剩下的还是建议使用namedquery
from gendry.
在某些场景下,要根据条件的不同在SQL里and上不同的语句,这个时候NameQuery
里的SQL可能还是需要大量的进行手动拼接,而当这种需求和较长的sql语句撞车,就只有求助于手动拼接SQL了,gendry无法解决

我理解你的需求了,你最终的sql语句可能需要根据上下文才能确定要哪些where条件,但是又是一个比较复杂的语句对吧。我们会认真考虑要不要做上这个功能,但是目前你还是只能先用NamedQuery手动拼接一下。等我们确定好了开发计划,会reopen这个issue
