我想在HQL中编写以下SQL查询-
select * from ITPMAST
inner join STKMAST on ITPMAST.ITPITP=STKMAST.stkstk where STKMAST.STKSIT='S101'
Itpmast类
public class Itpmast implements java.io.Serializable {
private String itpitp;
private Sizmast sizmast;
private User usdmastByItpaddusd;
private User usdmastByItpamdusd;
private Prmmast prmmast;
private Sctmast sctmast;
private String itpnam;
private short itpfcn;
private short itptcn;
private BigDecimal itpcpr;
private BigDecimal itpspr;
private String itpactyn;
private String itpbscode;
private String itpcolor;
private BigDecimal itpspr1;
private BigDecimal itpspr2;
private BigDecimal itpspr3;
private Date itpsactddt1;
private Date itpsactddt2;
private Date itpsactddt3;
private Date itpaddddt;
private String itpaddtime;
private Date itpamdddt;
private String itpamdtime;
private Short itpbscodeord;
private String itptrnactno;
private String itpactcode;
private Date itpsactddt;
private String itpprtflg;
private Set<Skumast> skumasts = new HashSet<Skumast>(0);
private Set<Igpmast> igpmasts = new HashSet<Igpmast>(0);
private Set<Dismastb> dismastbs = new HashSet<Dismastb>(0);
private Set<Dismastd> dismastds = new HashSet<Dismastd>(0);
private Set<Rbttran> rbttrans = new HashSet<Rbttran>(0);
private Set<Lytmast> lytmasts = new HashSet<Lytmast>(0);
private Set<Stkmast> stkmasts = new HashSet<Stkmast>(0);
private Set<Sslmast> sslmastsForSslitp = new HashSet<Sslmast>(0);
private Set<Sslmast> sslmastsForSslssl = new HashSet<Sslmast>(0);
}

}
我最大的尝试是
from Stkmast s
join fetch s.itpmast i where s.sitmast.sitsit=:siteCode and i.itpitp like :code
但是此HQL查询会产生许多SQL查询来获取数据。谢谢。
最佳答案
您需要将获取类型设置为join，而不是映射中的默认select。
Example：
<hibernate-mapping>
<class name="com.mkyong.common.Stock" table="stock">
<set name="stockDailyRecords" cascade="all" inverse="true"
table="stock_daily_record" batch-size="10" fetch="join">
<key>
<column name="STOCK_ID" not-null="true" />
</key>
<one-to-many class="com.mkyong.common.StockDailyRecord" />
</set>
</class>
</hibernate-mapping>
