1、数据库脚本
CREATE TABLE OLIVER_11(ID INT,VALUE VARCHAR(100)); INSERT INTO OLIVER_11 VALUES(1,'20%'); INSERT INTO OLIVER_11 VALUES(2,'OLIVER_QIN'); INSERT INTO OLIVER_11 VALUES(3,'AA''')
2、以下是DB2的转义字符
2.1 对“%”的转义
SELECT * FROM OLIVER_11 WHERE VALUE LIKE '%!%%' ESCAPE '!'
2.2 对"_"下划线的转义
SELECT * FROM OLIVER_11 WHERE VALUE LIKE '%!_%' ESCAPE '!'
2.3对“'”(单引号)的转义
SELECT * FROM OLIVER_11 WHERE VALUE LIKE '%''%'
2.4含有字符串拼接的单引号转义
SELECT VALUE||''||'_YUE'||'' FROM OLIVER_11 WHERE VALUE LIKE '%!_%' ESCAPE '!'
