如何实现MyBAtis仅更新SQL语句中指定的字段

// 对象 public class Entity { private String id = null; private int value = null; private Timestamp createTime = null; // getter and setter ... } // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFA...

// 对象 public class Entity { private String id = null; private int value = null; private Timestamp createTime = null; // getter and setter ... } // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFA...

// 对象 public class Entity { private String id = null; private int value = null; private Timestamp createTime = null; // getter and setter ... } // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFA...

// 对象 public class Entity { private String id = null; private int value = null; private Timestamp createTime = null; // getter and setter ... } // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFA...

// 对象 public class Entity { private String id = null; private int value = null; private Timestamp createTime = null; // getter and setter ... } // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFA...

// 对象 public class Entity { private String id = null; private int value = null; private Timestamp createTime = null; // getter and setter ... } // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFA

改成下面这样即可。 // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFAULT 0, cre_tim TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (id) )

update tab1 set name=replace(name,\\'abc\\',\\'d\\') where name like \\'abc%\\'

改成下面这样即可。 // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFAULT 0, cre_tim TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY (id) )

// 对象 public class Entity { private String id = null; private int value = null; private Timestamp createTime = null; // getter and setter ... } // 数据表 CREATE TABLE qai_entity ( id CHAR(10) NOT NULL, value INT NOT NULL DEFA...
