1. Table ‘jqp.spring_session’ doesn’t exist
我们有时在启动本地项目,或者启动git上下载的源码时,会报错如下错误:

1.1 分析问题
bad SQL grammar [DELETE FROM SPRING_SESSION WHERE EXPIRY_TIME < ?]; nested exception is java.sql.SQLSyntaxErrorException: Table 'jqp.spring_session' doesn't exist
,翻译成中文便是:错误的SQL语法[删除表SPRING_SESSION失败],因为jqp库中不存在spring_session表。
程序中为什么会报出这种错误呢?原来,我们在pom
中引入了如下依赖:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
1.2 解决问题
既然知道了问题,那么,可以采用如下方式解决
1.2.1 第一种解决方法
这种解决方法就是在pom文件中,注释掉当前依赖。
1.2.2 第二种解决方式
上文不是说没有spring_session
表吗,我们可以手动创建这这张表,如下代码所示:
DROP TABLE IF EXISTS SPRING_SESSION_ATTRIBUTES;
DROP TABLE IF EXISTS SPRING_SESSION;
-- 创建SPRING_SESSION表
CREATE TABLE SPRING_SESSION (
PRIMARY_ID CHAR(36) NOT NULL,
SESSION_ID CHAR(36) NOT NULL,
CREATION_TIME BIGINT NOT NULL,
LAST_ACCESS_TIME BIGINT NOT NULL,
MAX_INACTIVE_INTERVAL INT NOT NULL,
EXPIRY_TIME BIGINT NOT NULL,
PRINCIPAL_NAME VARCHAR(100),
CONSTRAINT SPRING_SESSION_PK PRIMARY KEY (PRIMARY_ID)
) ENGINE=INNODB ROW_FORMAT=DYNAMIC;
CREATE UNIQUE INDEX SPRING_SESSION_IX1 ON SPRING_SESSION (SESSION_ID);
CREATE INDEX SPRING_SESSION_IX2 ON SPRING_SESSION (EXPIRY_TIME);
CREATE INDEX SPRING_SESSION_IX3 ON SPRING_SESSION (PRINCIPAL_NAME);
-- 创建spring_session属性表
CREATE TABLE SPRING_SESSION_ATTRIBUTES (
SESSION_PRIMARY_ID CHAR(36) NOT NULL,
ATTRIBUTE_NAME VARCHAR(200) NOT NULL,
ATTRIBUTE_BYTES BLOB NOT NULL,
CONSTRAINT SPRING_SESSION_ATTRIBUTES_PK PRIMARY KEY (SESSION_PRIMARY_ID, ATTRIBUTE_NAME),
CONSTRAINT SPRING_SESSION_ATTRIBUTES_FK FOREIGN KEY (SESSION_PRIMARY_ID) REFERENCES SPRING_SESSION(PRIMARY_ID) ON DELETE CASCADE
) ENGINE=INNODB ROW_FORMAT=DYNAMIC;
2. Table x doesn’t exist
一般报出这种问题PreparedStatementCallback:bad SQL grammar [DELETE FROM xxx WHERE ?]...Table xxx doesn't exist
的原因是,项目所涉及到的数据库中没有当前表,如下所示:
org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [select * from Dynamic_Task where timer_Task_Status is null or timer_Task_Status = ? ]; nested exception is java.sql.SQLSyntaxErrorException: Table 'jqp.dynamic_task' doesn't exist
at org.springframework.jdbc.support.SQLErrorCodeSQLExceptionTranslator.doTranslate(SQLErrorCodeSQLExceptionTranslator.java:239) ~[spring-jdbc-5.3.14.jar:5.3.14]
at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:70) ~[spring-jdbc-5.3.14.jar:5.3.14]
at org.springframework.jdbc.core.JdbcTemplate.translateException(JdbcTemplate.java:1541) ~[spring-jdbc-5.3.14.jar:5.3.14]
at org.springframework.jdbc.core.JdbcTemplate.execute(JdbcTemplate.java:667) ~[spring-jdbc-5.3.14.jar:5.3.14]
at org.springframework.jdbc.core.JdbcTemplate.query(JdbcTemplate.java:713) ~[spring-jdbc-5.3.14.jar:5.3.14]
at org.springframework.jdbc.core.JdbcTemplate.query(JdbcTemplate.java:744) ~[spring-jdbc-5.3.14.jar:5.3.14]
at org.springframework.jdbc.core.JdbcTemplate.query(JdbcTemplate.java:757) ~[spring-jdbc-5.3.14.jar:5.3.14]
at org.springframework.jdbc.core.JdbcTemplate.query(JdbcTemplate.java:815) ~[spring-jdbc-5.3.14.jar:5.3.14]
at com.jqp.admin.db.service.impl.MysqlJdbcDaoImpl.find(MysqlJdbcDaoImpl.java:109) ~[classes/:na]
直接在项目中创建当前缺失的表即可。
3. You have an error in your SQL syntax;
nested exception is java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax
。
这种情况的错误一般是,我们在使用orm框架,比如mybatis框架、hibernate框架。我们在编写映射代码时,由于标点符号不正确,或者其他编写不正确,造成生成的mysql语句,出现了mysql语法的错误,如下代码所示:
SELECT
DATE_FORMAT( pay_order.pay_time, '%Y%m%d' ) AS pay_time,
pay_order.pay_type_code AS pay_type_code,
park.NAME AS park_name
FROM
`pay_order`
LEFT JOIN park_order ON pay_order.trade_pay_no = park_order.id
LEFT JOIN park ON park_order.park_id = park.id
WHERE
pay_order.STATUS = 2
<if test="trandate !=null and trandate!=''">and DATE_FORMAT(pay_order.pay_time,'%Y%m%d') = #{trandate}</if>
<if test="parkName !=null and parkName!=''">and park.name = #{parkName}</if>
<if test="payType !=null and payType!=''">and pay_order.pay_type_code = #{payType};</if>
GROUP BY
pay_time,
pay_type_code,
park_name
上述mysql
在Navicat
中可以执行,后来才发现在group by
关键字前面,也就是最后一个if的后面,多加了一个逗号,
此时,我们需要检查我们的映射代码,即一定要仔细检查mysql
。
4. Unknown column x in x
如下问题所述
java.sql.SQLSyntaxErrorException: Unknown column ‘lastname’ in ‘field list’; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Unknown column ‘lastname’ in ‘field list’
at org.springframework.jdbc.support.SQLErrorCodeSQLExceptionTranslator.doTranslate(SQLErrorCodeSQLExceptionTranslator.java:239)

这种错误一般是数据库中的字段与Java
程序实体pojo
或者entity类
中定义的字段不匹配。
观察发现mysql中为last_name
字段,经过驼峰转换可为lastName
,但pojo类中则定义了lastname,改为lastName即可。
5. Unknown column ‘xxx’ in ‘where clause’
如下代码所示:
@Override
public List<Enterprise> getUserEnterpriseList(User user) {
List<Enterprise> list = jdbcService.find("select * from enterprise where id in(" +
"select enterprise_id id from enterprise_manager " +
"where user_id = ? " +
"union all " +
"select enterprise_id from enterprise_user " +
"where user_id = ? ) ",Enterprise.class,user.getId(),user.getId());
return list;
}
报出的错误是:
错误原因是我在enterprise
表中未创建user_id
字段。
一般这种错误就是没有在指定表中创建对应的字段,在表中创建该字段即可。
