我在 sql 中添加了两列以通过 hibernate 获取值。我的数据库是 oracle,这些字段的数据类型是 i 编号。所以我用 long 和(也尝试过 Integer)创建了 bean,但是在检索值时(执行 valuesquery)。
它给了我一个错误
org.hibernate.type.LongType - could not read column value from result set
java.sql.SQLException: Invalid column name
at oracle.jdbc.driver.OracleStatement.getColumnIndex(OracleStatement.java:3711)

表定义:
CREATE TABLE "PRODUCTLIST"
(
PRICELIST_PUBLISH_KEY decimal(22) NOT NULL,
PRODUCT_NBR varchar2(54) NOT NULL,
PRODUCT_KEY decimal(22),
PRODUCT_DESCRIPTION varchar2(360),
PRODUCT_FAMILY_NBR varchar2(30),
PRODUCT_FAMILY_DESCR varchar2(180),
PRODUCT_GROUP_NBR varchar2(30),
PRODUCT_GROUP_DESCR varchar2(180),

PL_KEY decimal(22),
PRODUCTLIST varchar2(750),
SALES_KEY decimal(22),
PRODUCT varchar2(60),
DM_EXTRACTED_BY_USER varchar2(90)
)
sql:
Query query = session.createSQLQuery(channelQuery)
.addScalar("PRODUCT",Hibernate.STRING)
.addScalar("PRODUCTLIST",Hibernate.STRING)
.addScalar("PRODUCTKEY",Hibernate.LONG)
.addScalar("SALESKEY",Hibernate.LONG)
.setResultTransformer(Transformers.aliasToBean(SearchResult.class));
return query.list();
}
});
请帮我解决问题?
