包路径：com.psddev.dari.db.Query
类名称：Query
方法名：and

Query.and介绍

[英]Combines the given predicate with the current one using AND logic. If the current predicate is null, the given predicate replaces it. For example:

Query<Article> query = Query.from(Article.class); 
for (...) { 
    query.and("tags = ?", tag); 
}

is equivalent to:

Query<Article> query = Query.from(Article.class); 
for (...) { 
    if (isFirst) { 
        query.where("tags = ?", tag); 
    } else { 
        query.and("tags = ?", tag); 
    } 
}

[中]使用AND逻辑将给定谓词与当前谓词组合。如果当前谓词为null，则给定的谓词将替换它。例如：

Query<Article> query = Query.from(Article.class); 
for (...) { 
    query.and("tags = ?", tag); 
}

相当于：

Query<Article> query = Query.from(Article.class); 
for (...) { 
    if (isFirst) { 
        query.where("tags = ?", tag); 
    } else { 
        query.and("tags = ?", tag); 
    } 
}
