embed a language into an existing language.

I want to embed a language into an existing language.

The parameters of the xml SQL in Mybatis are like:

<select> SELECt * .... WHERE name=#{name}

</select>

I found the narration method for this post,

It says that you can use lazy-parsable + injection, but I don't know how to do it,

is there a specific tutorial?
