异常在插入图像插入SQL表使用BLOB对象

问题描述：

PreparedStatement pstmt; 
Connection conn = DriverManager.getConnection(
    "jdbc:jtds:sqlserver://Irfan:1433/Pictures", "sa", "[email protected]");  

java.sql.Blob bl=GetBolbDataFromDB(); 
InputStream fs = bl.getBinaryStream(); 
len = bl.length() ; 

query = ("insert into NewPics2 VALUES(?,?,?,?)"); 
pstmt = conn.prepareStatement(query); 
pstmt.setString(1, model); 
pstmt.setString(2, catid); 
pstmt.setString(3, ornid); 
**pstmt.setBinaryStream(4, fs);**

完整的堆栈跟踪如下

答

简单地把你的JDBC驱动程序不实现最新版本的jdbc：它没有方法setBinaryStream（）。这意味着你不能使用它。你可以尝试setBlob（）与完全读取的图像。

为FS的FileInputStream它waxworking罚款 – 2013-02-21 11:23:28

其他答案可能是替代品。您也可以尝试它们（对于不同版本的jdbc，支持该方法的不同重载） – 2013-02-21 11:32:56

答

从堆栈跟踪看来，您调用的方法是抽象的。根据文档，JtdsPreparedStatement.setBinaryStream()有三个参数：索引，流和长度。

尝试添加int作为长度参数：pstmt.setBinaryStream(4, fs);

答

尝试转换

java.sql.Blob bl=GetBlobDataFromDB(); 
String fs = bl.getBytes();
