一同事在写脚本时,遇到一个关于LIKE里面使用不同的变量类型导致查询结果不一致的问题,因为这个问题被不同的人问过好几次,索性总结一下,免得每次都要解释一遍,直接丢一篇博客岂不是更方便!其实看似有点让人不解的现象背后实质跟数据类型的实现有关. 下面我们构造这样一个类似的简单案例.如下所, CREATE TABLE TEST (ID ,), NAME ) ) INSERT INTO dbo.test SELECT 'abc32' INSERT INTO dbo.test SELECT 'abd32'
INSERT INTO TTT (NSAME, ID, AGE) VALUES ('AAA', '201023210816', '22'); 将上面的SQL格式改成以下的格式 AAA|201023210816|22 import os lists=[] paths = os.getcwd() for root,dirs,files in os.walk('wfyh'): for fn in files: lists.append(fn) for nmb in lists: dfile=open(
select count(*) from (SELECT A.* FROM (SELECT CD.*, nvl(CV.SUM_CI_BALANCE, 0) as SUM_CI_BALANCE, nvl(CV.SUM_LN_BALANCE, 0) as SUM_LN_BALANCE FROM OCRM_F_CI_CUST_DESC CD left join ( select cust_id, FR_ID, sum(CI_BALANCE) as sum_CI_BALANCE, sum(LN_BALA
int 转 String: //方式一: int i1 = 888; String s1 = Integer.toString(i1); //方式二: int i2 = 888; String s2 = String.valueOf(i2); //方式三: int i3 = 888; String s3 = i3+""; String 转 int : //方式一: String s = "888“; int i = Integer.parseInt(s); //方式二: in
