Master please help: Now the Catinfo table in SQL Server 2000 Database Busmgsys is named CATPHOTO, the type image type is used to store the image, and set a busmgsys data source in the ODBC data source, the username SA, password SA, now To read this image data from the database, the code is: public class readimage {public static void main (string [] args) {readimageFromDatabase ();
} Public void readimageFromDatabase () {Import javax.swing. *; Import java.io. *; try {// load JDBC driver class.Forname ("sun.jdbc.odbc.jdbcodbcdriver"); // with JDBC-ODBC bridge to connect connection con = DriverManager.getConnection ( "jdbc: odbc: BusMgSys", "sa", "sa"); Statement statement = con.createStatement (); ResultSet result = statement.executeQuery ( "select catPhoto from CatInfo") If (Result.next) {// Defines a Byte [] array to temporarily read photos read from the database Byte [] imageDataS = null; // Define a stream of input flows to accept streams read from the database InputStream Imagestream;
// Log from the number of images in the database Imagestream = ((InputStream) Result.GetBinaryStream ("CatPhoto")); // is in this line
// Put the image data into the ImageDataS.Read (ImageDataS);} catch (exception e) {E.PrintStackTrace ();}}}
One runs to imagestream = ((InputStream) Result.getBinaryStream ("CatPhoto")); this line has a lower case error:
