Problem
A table named “category” in MySQL database, contains a “DESC” keyword as column name.
CREATE TABLE `category` (
`CATEGORY_ID` int(10) unsigned NOT NULL AUTO_INCREMENT,
`NAME` varchar(10) NOT NULL,
`DESC` varchar(255) NOT NULL,
PRIMARY KEY (`CATEGORY_ID`) USING BTREE
);
Hibernate XML mapping file
<hibernate-mapping>
<class name="com.mkyong.stock.Category" table="category" catalog="mkyongdb">
...
<property name="desc" type="string">
<column name="DESC" not-null="true" />
</property>
...
</class>
</hibernate-mapping>
Or Hibernate annotation
@Column(name = "DESC", nullable = false)
public String getDesc() {
return this.desc;
}
When insert into category table, hits following error message :
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
You have an error in your SQL syntax; check the manual that corresponds to your
MySQL server version for the right syntax to use near 'DESC)
values ('CONSUMER', 'CONSUMER COMPANY')' at line 1
... 35 more
Solution
In Hibernate, to insert into “keyword” column name, you should enclose it like this ‘[column name]‘.
Hibernate XML mapping file
<hibernate-mapping>
<class name="com.mkyong.stock.Category" table="category" catalog="mkyongdb">
...
<property name="desc" type="string">
<column name="[DESC]" not-null="true" />
</property>
...
</class>
</hibernate-mapping>
Or Hibernate annotation
@Column(name = "[DESC]", nullable = false)
public String getDesc() {
return this.desc;
}
Thanks, this was very useful!
Good day sir, how do you do this in PHP? i’m having trouble myself…
mysql_query(“INSERT INTO items (desc) VALUES (‘$desc’)”);
this is not even remotely related to PHP … you’re on the wrong website, this article is about HIBERNATE and JAVA, your column-problems dont apply here
