1、findByQuery(QueryExecutor query) result QueryResult increase List getFirstColumn(boolean distinct) Method , It is convenient to extract the single column values of the result set to form a one-dimensional array

2、sql file filters add clone Method

<sql id="qstart_clone_param_case"><filters>    <!--  It is applicable when the front end has only single date , Construct a endDate Form date range filter  -->    <clone param="beginDate" as-param="endDate"/>    <to-date params="endDate" increment-unit="days" format="yyyy-MM-dd" increment-time="1"/></filters><value><![CDATA[	select * from sqltoy_trans_info_15d t 	where t.trans_date>=:beginDate	#[and t.trans_date<:endDate]]]></value></sql>

sqltoy The key advantage of ：

//------------------ understand  sqltoy The key advantage of : -------------------------------------------------------------------------------------------*///1、 The simplest and most intuitive sql Compiling mode ( It's not just query statements ), Using the pre-processing regularization method of conditional parameters , Give Way sql The statement part is highly consistent with the client //2、sql Comments are supported in ( Evaded the right hint The influence of characteristics , know hint Do you ? search oracle hint), And dynamic update loading , It is convenient for the management of the whole process of development and later maintenance //3、 Support cache translation and reverse cache condition retrieval ( Match the name to the exact key), Realization sql Simplify and greatly improve performance //4、 Support fast paging and paging optimization , Achieve the highest level of paging optimization , It also takes into account cte Multiple with as Optimization support in case //5、 Support parallel query //6、 Completely eradicate sql Injection problem //7、 Support row column conversion 、 Group summary and average 、 On a year-on-year basis , It's about solving complex problems with algorithms sql, It's also solved sql Cross database issues //8、 Support automatic adaptation of reserved words //9、 Support cross database function self adaptation , Thus, it is very helpful for a set of code to adapt to a variety of databases and facilitate the commercialization , such as oracle Of nvl, When sql stay mysql The environment is automatically replaced with ifnull//10、 Support sub database and sub table //11、 Provides access top、 take random Record 、 Tree table structure construction and recursive query support 、updateFetch A single interaction completes practical functions such as modification and query //12、sqltoy Of update、save、saveAll、load  etc. crud Operation circumvents jpa The defects of , See update(entity,String...forceUpdateProps) and updateFetch//13、 It provides a very humanized condition processing ： Exclusive conditions 、 Addition and subtraction of date conditions and extraction at the end of the month and the beginning of the month //14、 The query result date is provided 、 Number formatting 、 Safe desensitization treatment , Make complicated things simple , Greatly simplify sql Or the secondary processing of results //-----------------------------------------------------------------------------------*/

sqltoy Feature introduction ：

• sqltoy The core construction idea of

• sqltoy Comparison of mybatis(plus) and fluent mybatis The core of ： Query statement writing 、 Readability 、 Maintainability

• Objectification crud It's the foundation , but sqltoy Targeted improvements ：update、updateSaveFetch、updateFetch etc.

• sqltoy Cache translation , Greatly reduce table Association and simplify sql, Improve your query performance at the geometric level

• Ultimate paging , It also helps you achieve a significant improvement in query performance

1. Quick Pagination :@fast() Realize the first retrieval of single page data and then associated query , Greatly increase the speed
2. Paging optimizer :page-optimize Let the paging query change from twice to 1.3~1.5 Time ( Using cache to realize the total number of records with the same query conditions, there is no need to query repeatedly in a certain period
3. sqltoy The process of paging to get the total record is not simple select count(1) from ( original sql); It's intelligent judgment whether it becomes :select count(1) from 'from After statement ', And automatically eliminate the outermost order by
4. sqltoy Support parallel query ：parallel="true", Query the total number of records and single page data at the same time , Significantly improved performance
