在java中呼叫Oracle儲存過程時，出現異常：java.sql.SQLException: ORA-00928: 缺失 SELECT 關鍵字

//java程式碼
    @Test
    public void testProcedure(){
        Connection conn = null;
        CallableStatement call = null ;
        try {
            conn = JDBCUtils.getconnection();
            **call = conn.prepareCall("(call testprocedure(?,?,?))"
 
);**
            //in引數賦值
            call.setInt(1,7839);
            //out引數宣告
            call.registerOutParameter(2,OracleTypes.VARCHAR);
            call.registerOutParameter(3, oracle.jdbc.OracleTypes.NUMBER);
            //執行
            call.execute();
            //取出
            String name = call
 
.getString(2);
            float sal = call.getFloat(3);           
            System.out.println("ename="+name+" sal="+sal);          
        } catch (SQLException e) {
            e.printStackTrace();
        }finally{
            JDBCUtils.release(conn, call, null);
        }
    }

錯誤出現在call.execute()。 錯誤原因為：call = conn.prepareCall(“(call testprocedure(?,?,?))”);

    {?= call <procedure-name>[(<arg1>,<arg2>, ...)]}
       {call <procedure-name>[(<arg1>,<arg2>, ...)]}

更改為 conn.prepareCall(“{*call testprocedure(?,?,?)}*”) 或者去掉括號conn.prepareCall(“call testprocedure(?,?,?)”)

執行成功

ename=KING sal=7600.0
