中收到此错误 Invalid column name
?我正在尝试从 oracle 数据库中获取表信息。我将我的查询放入 db eaver 它的成功,请告诉我本机查询的最佳实践如何...
Hibernate: SELECT TABLE_NAME, COLUMN_NAME, DATA_TYPE FROM ALL_TAB_COLUMNS WHERE TABLE_NAME='BPN_AKTA'

我的模特
@Entity(name="ALL_TAB_COLUMNS")
public class QueryTableAttModel
public String getTABLE_NAME()
return TABLE_NAME;
public void setTABLE_NAME(String TABLE_NAME)
this.TABLE_NAME = TABLE_NAME;
public String getCOLUMN_NAME()
return COLUMN_NAME;
public void setCOLUMN_NAME(String COLUMN_NAME)
this.COLUMN_NAME = COLUMN_NAME;
public String getDATA_TYPE()
return DATA_TYPE;
public void setDATA_TYPE(String DATA_TYPE)
this.DATA_TYPE = DATA_TYPE;
private String TABLE_NAME;
private String COLUMN_NAME;
private String DATA_TYPE;
private String id;
@Id
public String getId()
return id;
public void setId(String id)
this.id = id;
【问题讨论】:
【参考方案1】:问题是表ALL_TAB_COLUMNS
没有单列主键。您应该使用基于OWNER
、TABLE_NAME
、COLUMN_NAME
列的复合主键。
例如,您可以将@IdClass
annotation 用于复合主键映射:
@Entity
@Table(name = "ALL_TAB_COLUMNS")
@IdClass(QueryTableAttModelPK.class)
public class QueryTableAttModel
private String owner;
private String tableName;
private String columnName;
private String dataType;
public QueryTableAttModel()
@Id
@Column(name = "OWNER")
public String getOwner()
return owner;
public void setOwner(String owner)
this.owner = owner;
@Id
@Column(name = "TABLE_NAME")
public String getTableName()
return tableName;
public void setTableName(String tableName)
this.tableName = tableName;
@Id
@Column(name = "COLUMN_NAME")
public String getColumnName()
return columnName;
public void setColumnName(String columnName)
this.columnName = columnName;
@Column(name = "DATA_TYPE")
public String getDataType()
return dataType;
public void setDataType(String dataType)
this.dataType = dataType;
QueryTableAttModelPK
类在哪里
import java.io.Serializable;
import java.util.Objects;
public class QueryTableAttModelPK implements Serializable
private String owner;
private String tableName;
private String columnName;
public QueryTableAttModelPK()
public QueryTableAttModelPK(String owner, String tableName, String columnName)
this.owner = owner;
this.tableName = tableName;
this.columnName = columnName;
public String getOwner()
return owner;
public void setOwner(String owner)
this.owner = owner;
public String getTableName()
return tableName;
public void setTableName(String tableName)
this.tableName = tableName;
public String getColumnName()
return columnName;
public void setColumnName(String columnName)
this.columnName = columnName;
@Override
public boolean equals(Object obj)
if (this == obj) return true;
if (obj == null) return false;
if (getClass() != obj.getClass()) return false;
QueryTableAttModelPK other = (QueryTableAttModelPK) obj;
return Objects.equals(owner, other.owner)
&& Objects.equals(tableName, other.tableName)
&& Objects.equals(columnName, other.columnName);
@Override
public int hashCode()
return Objects.hash(owner, tableName, columnName);
然后您可以使用本机查询:
List<QueryTableAttModel> results = em.createNativeQuery(
"select OWNER, TABLE_NAME, COLUMN_NAME, DATA_TYPE from ALL_TAB_COLUMNS where TABLE_NAME = :table",
QueryTableAttModel.class)
.setParameter("table", "ALL_TAB_COLUMNS")
.getResultList();
jpql/hql 查询:
List<QueryTableAttModel> results = em.createQuery(
"select q from QueryTableAttModel q where q.tableName = :table",
QueryTableAttModel.class)
.setParameter("table", "ALL_TAB_COLUMNS")
.getResultList();
或者通过PK找实体:
QueryTableAttModel qTable = em.find(
QueryTableAttModel.class,
new QueryTableAttModelPK("SYS", "ALL_TAB_COLUMNS", "CHAR_LENGTH")
);
