SQL*Loader must have a way of knowing the location of the various fields in the input file. Oracle calls the individual items in the datafile fields, and there is no direct correspondence between these fields and the columns in the table in which you are loading the data. The process of mapping fields in the input datafile to the table columns in the database is called field setting, and it is the biggest contributor to CPU time taken during the load. The POSITION clause specifies exactly where in the data record the various fields are. You have two ways to specify the location of the fields: relative and absolute. Relative position implies that you specify the position of a field with respect to the position of the preceding field, as shown in the following example: employee_id POSITION(*) NUMBER EXTERNAL 6 employee_name POSITION(*) CHAR 30 In this example, the load starts with the first field, employee_id. SQL*Loader then expects employee_name to start in position 7 and continue for 30 characters. It will look for the next field starting at position 37, and so on. When you use the POSITION clause in an absolute position sense, you just specify the position at which each field starts and ends, as follows: employee_id POSITION(1:6) INTEGER EXTERNAL employee_name POSITION(7:36) CHAR

The data types used in the control file refer to the input records only and aren t the same as the column data types within the database tables. The following are the main data types used in SQL*Loader control files: INTEGER(n) binary integer, where n can be 1, 2, 4, or 8 SMALLINT CHAR INTEGER EXTERNAL FLOAT EXTERNAL DECIMAL EXTERNAL

After each column s data type is specified, you can specify a delimiter, which indicates how the field should be delimited. You can delimit data by using one of the following two clauses: TERMINATED BY or ENCLOSED BY. TERMINATED BY limits the field to the character specified and denotes the end of a field. Here are a couple of examples: TERMINATED BY WHITESPACE TERMINATED BY "," The first example indicates that the field is terminated by the first blank that is encountered. The second example simply indicates that the fields are separated by commas. The ENCLOSED BY " " delimiter specifies that the field is enclosed by a pair of quotation marks. Here is an example: FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'

Figure 1-46. Two classes coupled by ambiguous type coupling Listing 1-14 shows a simple C# implementation. Listing 1-14. A Simple Implementation, Causing ATC Between A and B public class A { public void UseB(B theB) { theB.M1(); // call method of B } } public class B { public void M1() { // ... } } Class A doesn t instantiate class B, but instead receives a reference to B from another object. To eliminate the ATC between A and B, you need to remove from A the reference to type B. Instead of class A calling a method through the interface B, make A call B.M1 using a method reference. Use an active Builder to initialize A s method reference, resulting in the coupling diagram shown in Figure 1-47.

Tip Oracle recommends that you avoid delimited fields and choose positional fields (using the POSITION parameter) where possible. Choosing positional fields means that the database avoids scanning the datafile to find the delimiters you chose, thus reducing processing time.

You can apply SQL functions to the field data before loading it into table columns. Only SQL functions that return single values can be used for transforming field values in general. The field should be denoted inside the SQL string as field_name. You specify the SQL function(s) after you specify the data type for the field, and you enclose the SQL string in double quotation marks, as shown in the following examples: field_name CHAR TERMINATED BY "," "SUBSTR(:field_name, 1, 10)" employee_name POSITION 32-62 CHAR "UPPER(:ename)" salary position 75 CHAR "TO_NUMBER(:sal,'$99,999.99')" commission INTEGER EXTERNAL "":commission * 100" As you can see, the application of SQL operators and functions to field values before they are loaded into tables helps you transform the data at the same time you are loading it. This is a handy feature.
