無效的列類型：getInt沒有實現類oracle.jdbc.driver.T4CRowidAccessor

我要張貼在Oracle數據庫11g的數據和我輸入使用輸入字段中的數據輸入到數據庫中的數據，但只是ID coulmn和另一個字符串coulmn是得到正確的數據，但另一個coulmn得到空或0，所以我不能解決這個問題，在運行時我有這個錯誤無效的列類型：getInt沒有實現類oracle.jdbc.driver.T4CRowidAccessor

Invalid column type: getInt not implemented for class oracle.jdbc.driver.T4CRowidAccessor

這是我的代碼

public Client newClient(Client client){ 
    try { 
     con = DBConnection.getConnection(driver, url, name, pass);  
     pstmt = con.prepareStatement("INSERT INTO CLIENT (CID, FIRSTNAME, LASTNAME, CAREER, CSALARY) VALUES (CLIENT_ID.nextval, ?, ?, ?, ?)", Statement.RETURN_GENERATED_KEYS); 

     pstmt.setString(1, client.getFirstName()); 
     pstmt.setString(2, client.getLastName()); 
     pstmt.setString(3, client.getCareer()); 
     pstmt.setInt(4, client.getcSalary()); 
     pstmt.executeUpdate();  
     rs = pstmt.getGeneratedKeys(); 
     rs.next(); 
     Integer id = rs.getInt(1); 
      client.setcId(id);   
    }catch(Exception ex){ 
     ex.printStackTrace(); 
     return null; 
    }finally{ 
     try{ rs.close(); }catch (Exception e){} 
     try{ pstmt.close();}catch (Exception e){} 
     try{ con.close();}catch (Exception e){} 
    }//finally 
    return client; 
}

}

@XmlRootElement 
    public class Client { 
private Integer cId; 
private String firstName; 
private String lastName; 
private String career; 
private int cSalary; 
public Integer getcId() { 
    return cId; 
} 
public void setcId(Integer cId) { 
    this.cId = cId; 
} 
public String getFirstName() { 
    return firstName; 
} 
public void setFirstName(String firstName) { 
    this.firstName = firstName; 
} 
public String getLastName() { 
    return lastName; 
} 
public void setLastName(String lastName) { 
    this.lastName = lastName; 
} 
public String getCareer() { 
    return career; 
} 
public void setCareer(String career) { 
    this.career = career; 
} 
public int getcSalary() { 
    return cSalary; 
} 
public void setcSalary(int cSalary) { 
    this.cSalary = cSalary; 
}

}

，這是我的SQL

CREATE TABLE "AHMAD"."CLIENT" 
    ("CID" NUMBER(*,0) NOT NULL ENABLE, 
"FIRSTNAME" VARCHAR2(255 BYTE), 
"LASTNAME" VARCHAR2(255 BYTE), 
"CAREER" VARCHAR2(255 BYTE),

plz幫助我的數據插入到表，但不是完全地和我有這個運行時錯誤

的使用Statement.RETURN_GENERATED_KEYS時，Oracle JDBC驅動程序不會返回生成的ID，因此生成的密鑰ResultSet的第一列是不是int，而是返回一個ROWID（見JDBC tutorial on rowids）插入行（這樣你就可以自己查詢行）。據我所知，原因是Oracle沒有身份類型，所以實際上並不知道哪個字段是生成的密鑰。

相反，您應該能夠使用prepareStatement(String sql, int[] columnIndexes)或prepareStatement(String sql, String[] columnNames)明確指定要返回的列。

將數據插入表中，並且id是自動增量，但整行像這樣1003 \t null \t null \t Dev \t 0原諒我iam初學者，並有錯誤 – Ahmad

再次閱讀我的答案。問題是，您認爲getGeneratedKeys的第一列包含插入行的「CID」列的值，但它不包含。它包含rowid，它是由Oracle定義的特殊僞列。 –

prepareStatement（SQL字符串，INT [] columnIndexes）工程的Oracle 11g –

像馬克的建議，我只是遇到了同樣的問題，找到了解決辦法：

String generatedColumns[] = { "ID" }; 
stmt = con.prepareStatement(query, generatedColumns);

你執行查詢後，執行以下操作以獲取插入的ID。

rs = stmt.getGeneratedKeys(); 
rs.next(); 
rs.getInt(1);

謝謝！我有一段時間出現這個錯誤，但從未需要插入後使用任何ID ..但現在我有需要，問題必須解決！注意：爲什麼oracle太過時了！ –

不知道這個問題是否是原來決心或沒有，但我面臨同樣的問題，並得到了由實體類INT更換整數（在你的情況下，它是客戶類）

解決
