querydsl

问题 I am new to elastic search and I am confused between must and filter. I want to perform an and operation between my terms, so I did this POST /xyz/_search { "query": { "bool": { "must": [ { "term": { "city": "city1" } }, { "term": { "saleType": "sale_type1" } } ] } } } which gave me the required results matching both the terms, and on using filter like this POST /xyz/_search { "query": { "bool": { "must": [ { "term": { "city": "city1" } } ], "filter": { "term": { "saleType": "sale_type1" } }

问题 I need to implement sql query like: SELECT * FROM (SELECT a FROM b WHERE a.z = 1) WHERE rownum <=1; How can I write such statement with QueryDSL (I am not using JPA and JDO - only clean sql)? 回答1: Querydsl SQL emulates paging of all the supports databases, so you can write directly query.from(a) .where(a.z.eq(1)) .limit(1) .list(a); If you need to write this via a subquery then like this query.from( new SQLSubQuery().from(a).where(a.z.eq(1)).list(a).as(a)) .where(rownum.loe(1)) .list(a); 来源：

问题 Is it possible to do the following query in QueryDSL? SELECT p.* FROM parts_table p LEFT JOIN inventory_balance_table i ON (p.part_no = i.part_no AND i.month = MONTH(CURRENT_DATE) AND i.year = YEAR(CURRENT_DATE)); Inventory balance stores inventory data for every part number/month/year; I need the only the data for the current year and month. I've gotten the basic left join down: QPartsTable qParts = QPartsTable.partsTable; QInventoryBalance qBalance = QInventoryBalance.inventoryBalance;

问题 I am in little hurry so, i just want to ask a quick question about querydsl. According to my research, query dsl doesn't support stored procedure but can support database functions. My Question is how can we invoke those database functions using querydsl? 回答1: You can use TemplateExpression based injections of arbitrary JPQL syntax into your query. e.g. query.where(Expressions.booleanTemplate("func1({0}, {1})", arg1, arg2)); If you use Hibernate 4.3 or any other JPA 2.1 compliant provider you

问题 Libaries Used Spring Boot 1.3.2.RELEASE QueryDSL 3.7.2 QueryDSL Maven Plugin 1.1.3 Hibernate 4.3.11.Final Issue Currently, I have a Spring Boot application that has some basic CRUD functionality using Spring Data JPA (backed by Hibernate), and auditing using Spring Data Envers.
