Notice the following in particular: Virginia,USA in department 10: This results from input data that was "Virginia,USA". This input data field had to be enclosed in quotes to retain the comma as part of the data. Otherwise, the comma would have been treated as the end-of-field marker, and Virginia would have been loaded without the USA text. Va, "USA": This resulted from input data that was "Va, ""USA""". SQLLDR counted the double occurrence of " as a single occurrence within the enclosed string. To load a string that contains the optional enclosure character, you must ensure the enclosure character is doubled up.

Another popular format is tab-delimited data, which is data separated by tabs rather than commas. There are two ways to load this data using the TERMINATED BY clause: TERMINATED BY X'09' (the tab character using hexadecimal format; in ASCII, 9 is a tab character) TERMINATED BY WHITESPACE

The two are very different in implementation, as the following shows. Using the DEPT table from earlier, we ll load using this control file: LOAD DATA INFILE * INTO TABLE DEPT REPLACE FIELDS TERMINATED BY WHITESPACE (DEPTNO, DNAME, LOC) BEGINDATA 10 Sales Virginia It is not readily visible on the page, but there are two tabs between each piece of data here. The data line is really 10\t\tSales\t\tVirginia where the \t is the universally recognized tab escape sequence. When you use this control file with the TERMINATED BY WHITESPACE clause as previously, the resulting data in the table DEPT is: ops$tkyte@ORA11GR2> select * from dept; DEPTNO DNAME LOC ---------- -------------- ------------10 Sales Virginia

TERMINATED BY WHITESPACE parses the string by looking for the first occurrence of whitespace (tab, blank, or newline), and then it continues until it finds the next non-whitespace character. Hence, when it parsed the data, DEPTNO had 10 assigned to it, the two subsequent tabs were considered as whitespace, Sales was assigned to DNAME, and so on. On the other hand, if you were to use FIELDS TERMINATED BY X'09', as the following modified control file does FIELDS TERMINATED BY X'09' (DEPTNO, DNAME, LOC ) you would find DEPT loaded with the following data: ops$tkyte@ORA11GR2> select * from dept; DEPTNO DNAME LOC ---------- -------------- ------------10 Sales Here, once SQLLDR encountered a tab, it output a value. Hence, 10 is assigned to DEPTNO, and DNAME gets NULL since there is no data between the first tab and the next occurrence of a tab. Sales gets assigned to LOC. This is the intended behavior of TERMINATED BY WHITESPACE and TERMINATED BY <character>. Which is more appropriate to use will be dictated by the input data and how you need it to be interpreted. Lastly, when loading delimited data such as this, it is very common to want to skip over various columns in the input record. For example, you might want to load fields 1, 3, and 5, skipping columns 2 and 4. To do this, SQLLDR provides the FILLER keyword. This allows you to map a column in an input record, but not put it into the database. For example, given the DEPT table and the last control file from earlier, we can modify the control file to load the data correctly (skipping over the tabs) using the FILLER keyword: LOAD DATA INFILE * INTO TABLE DEPT REPLACE FIELDS TERMINATED BY x'09' (DEPTNO, dummy1 filler, DNAME, dummy2 filler, LOC) BEGINDATA 10 Sales Virginia The resulting DEPT table is now as follows: ops$tkyte@ORA11GR2> select * from dept; DEPTNO DNAME LOC ---------- -------------- ------------10 Sales Virginia
