有则更新，无则插入
需求：批量设置数据时，数据库中有数据则进行更新操作、没有则进行插入操作。
实现：MERGE INTO 语法
使用示例：
MERGE INTO TABLENAME1 T1 USING(SELECT * FROM DUAL) T2 ON (T1.F_DWBH = ? AND T1.F_DATE = ?)
WHEN MATCHED THEN UPDATE SET T1.F_COLUMN1 = ?,T1.F_COLUMN2=?
WHEN NOT MATCHED THEN INSERT (F_COLUMN1, F_COLUMN2, F_COLUMN3, F_COLUMN4, F_COLUMN5)
VALUES (?,?,?,?,?));行转列后、动态组织显示列
需求：查询展示中动态组织显示某些列。
实现：通过一个或者两个临时表进行数据组织展示。
本例实现思路：
/**
* 根据统计分类"银行"统计每个单位在每个银行账户的数量。
* 查询视图结果：单位编号、单位名称、合计、各银行列...
* 1、统计每个单位账户得银行列动态创建临时表。
* <p>
* 2、根据单位编号和银行编号更新合计和银行下的账户数量
* 2-1、查询每个单位在每个银行的账户数量。
* 2-2、查询每个单位银行账户数量的合计。
* <p>
* 3、更新临时表每个单位账户的合计，每个单位各个银行下的账户数量。
* 3-1、根据 2-1 统计的每个银行的账户数量更新临时表。
* 3-2、根据 2-2 统计的每个银行的账户数量更新临时表。
*
* @return
*/效果展示：
查询结果银行列动态显示
查询结果币种列动态显示
