For example, suppose you have an external datafile named sales_data that contains detailed information about your firm s sales data for the last year. Your firm wants to perform product and time cost analysis based on this raw data. You create a cost table to do this analysis. Now, the sales_ data datafile contains a lot of detailed information on costs, but your company wants the data to be aggregated, say on the basis of regions. External tables are excellent for this kind of analysis, where you have large amounts of raw data available, but you need only certain transformed parts of this data. Traditionally, data warehousing DBAs had to create staging tables to first transform data, before loading it into the data warehouse. Using just the SQL*Loader, you would need to load the raw data into your database first, and then apply the necessary transformations to it. Using an external table, you can perform the loading and transform operations in one step! Now, let s look at how to create and populate external tables. zxing barcode reader java Barcode in Java | Generate, Read, Scan Barcode in Java using ...

ZXing ("zebra crossing") TypeScript is an open-source, multi-format 1D/2D barcode image processing library ported to TypeScript from Java. The external table description is also called the external table layer, and it is basically a description of the columns in your external table. This external table layer, along with the access driver, maps the data in the external file to the external table definition. Listing 13-3 shows how to create an external table. Listing 13-3. Creating an External Table SQL> CREATE TABLE sales_ext( 2 product_id NUMBER(6), 3 sale_date DATE, 4 store_id NUMBER(8), 5 quantity_sold NUMBER(8), 6 unit_cost NUMBER(10,2), 7 unit_price NUMBER(10,2)) 8 ORGANIZATION EXTERNAL ( 9 TYPE ORACLE_LOADER 10 DEFAULT DIRECTORY ext_data_dir 11 ACCESS PARAMETERS 12 (RECORDS DELIMITED BY NEWLINE 13 BADFILE log_file_dir:'sales.bad_xt' 14 LOGFILE log_file_dir:'sales.log_xt' 15 FIELDS TERMINATED BY "|" LDRTRIM 16 MISSING FIELD VALUES ARE NULL) 17 LOCATION ('sales.data')) 18* REJECT LIMIT UNLIMITED; Table created.

From http://www.vineetmanohar.com/2010/09/ java - barcode - api / ... Figure 1-61. Bidirectional static coupling between parent and children The problem is that the Parent requires the Child to be present at build time, but the Child also requires the Parent to be present at build time. The Parent and Child classes have circular coupling. If both classes are part of the same component, you might be able to compile the component, but some languages and compilers don t allow circular coupling under any conditions. For example, if you implement the system using C++, you might have two header files called Parent.h and Child.h that contain the class declarations. However, Parent.h would need to include Child.h and vice versa, resulting in a circular file reference. Some C++ compilers refuse to compile either class. The problem gets worse if Parent and Child are packaged in separate components, as shown in Figure 1-62. zxing read barcode example java Java Code Examples com.google.zxing. Reader - Program Creek

The statement CREATE TABLE sales_ext (. . .) describes the external table structure, with the ORGANIZATION EXTERNAL clause that follows it indicating that this isn t going to be a regular Oracle table, but an external table. The CREATE statement for an external table is very similar to that of a regular table, except that in addition to the column definitions, you must provide the mapping for the columns to the data fields in the external datafile. In addition, the external table creation statement must provide the operating system location of the external datafile. The ACCESS PARAMETERS clause, somewhat similar to the OPTIONS clause in a SQL*Loader control file, indicates the various options chosen, as well as the location of the bad file and log file. Several external table parameters are available to specify the format of the data. Important among them are the following: RECORD_FORMAT_INFO: This is an optional clause. The default is RECORDS DELIMITED BY NEWLINE. FIXED: When you specify a fixed length by using the FIXED clause, you re indicating that all records in the external file are of the same length. ACCESS PARAMETERS (RECORD FIXED 20 FIELDS (. . .)) VARIABLE: The VARIABLE clause indicates that each record may be a different size, indicated by a number of digits before the beginning of each record.
