实际测试使用
这里结合Matrix 官方例子来看。

publicstaticfinal String TABLE_NAME_CONTACT = "contact";
privatestatic TestDBHelper mHelper = null;

这里新建了几个数据库表：
testTable：正常的表，integer 类型的id作为主键
testTableAutoIncrement：id 作为主键，且是自增属性
testTableWithoutRowid：设置了withoutRowid属性
testTableRedundantIndex：设置多个索引
contact:主要用于多条件查询
以下为测试的sql语句：
publicstatic String[] getTestSqlList() {
String[] list = new String[]{
"select * from testTable",//select *"select name from testTable where age>10",//no index"select name from testTableRedundantIndex where age&2 != 0",//not use index"select name from testTableRedundantIndex where name like 'j%'",//not use index"select name from testTableRedundantIndex where name = 'jack' and age > 20",
