There is one way in which PL/SQL is just like every other programming language you will ever use: It (the PL/SQL runtime engine) does only exactly what you tell it to do. Each block of PL/SQL code you write contains one or more statements implementing complex business rules or processe...
活动之间通过顺序流(sequence flow)连接,在流程图中是一个有向箭头。在执行流程实例时,执行(execution)会从启动事件沿着顺序流流向下一个活动。 离开排他网关(带有X的菱形)的顺序流很特别:都以表达式(expression)的形式定义了条件(condition) 。当流程实例的执行到达这个网关时,会计算条件,并使用第一个计算为true的...
act_ru_execution(执行表) 一个流程启动之后, 所有开始运行且未结束的活动(org.flowable.bpmn.model.Activity-所有任务的父类),都会在此本中有相关记录, 包括流程实例本身. 流程启动后先把流程实例存为一个execution,然后是下一待处理任务, 任务结束(完成)之后从此表中删除, 并添加下一个任务, 直到所有任务都结...
通过调用堆栈发现sql语句来自AbstractJdbcDatabase.getConnectionSchemaName: protectedStringgetConnectionSchemaName(){if(this.connection==null){returnnull;}elseif(this.connectioninstanceofOfflineConnection){return((OfflineConnection)
As soon as digital tasks - or entire processes - are to be executed repetitively and reliably, an automated solution is needed. In addition to the pure execution of work steps, other aspects are important: 一旦数字任务(或整个流程)要重复可靠地执行,就需要自动化解决方案。除了纯粹的工作步骤执行外...
System.out.println("为 "+ execution.getVariable("employee") +" 申请了 "+ execution.getVariable("nrOfHolidays") +" 天假期。"); } } 这时,我们可以看到这样的效果 当然,使用Flowable还有一个很方便的地方,就是我们可以去获取流程实例的审核数据和历史数据 ...

Transact-SQL provides special words called control-of-flow language that control the flow of execution of Transact-SQL statements, statement blocks, user-defined functions, and stored procedures. Without control-of-flow language, separate Transact-SQL statements are performed sequentially, as they occur...
