Several of the methods in this class which have a String-based sql query and params in a Listor Object[] supportnamedornamed ordinalparameters. These methods are useful for queries with large numbers of parameters - though the GString variations are often preferred in such cases too. Named pa...

user = 'user-name'source.password = 'password'def db = new groovy.sql.Sql(source) 提交查询当查询包含通配符时,使用PreparedStatement是明智的。当您在额外列表中提供值列表或语句为GString时,Groovy SQL会自动执行此操作。因此,以下每种方法都有三种变体:method('SELECT ... ')method('SELECT ...?,?',...

finalresults = sql.rows(query, search: searchString) results } } We can even make thegroovy.sql.Sqlinstance a Spring bean in our Grails application. Then we can inject theSqlinstance in for example a Grails service. Ingrails-app/conf/spring/resources.groovywe define theSqlbean: ...
eachRow( sqlQuery, {closure} ): This method is generally used to retain/modify the whole ResultSet based on some condition. The second argument of this method i.e.,clousureactually consists as set of statements to be executed for each of the result set’s entity. For example ...
def sql = Sql.newInstance( 地址, 用户名, 密码, 驱动 ) 实现样例如下: import groovy.sql.Sql //通过读取配置文件连接数据库 def DBProperties = testRunner.testCase.getTestStepByName( "DBProperties" ); def sql = Sql.newInstance(DBProperties.getPropertyValue( "connection-url" ),DBProperties.getProper...
sql.append(overallQuery); sql.append("(" + NEWLINE); URL 与 Controller 的命名约定: Controller 即 TeamController.groovy 文件,可以看到如下内容: class TeamController { def index = { redirect(action:list,params:params) } // the delete, save and update actions only accept POST requests ...
The example also used Sql.newInstance and Sql.eachRow(GString,Closure). The latter method allows for easy application of a closure to the results of the query. The it special word is the default name for items being processed in the closure. In this case,it can be thought of a a row...
