Comparison operators compare a certain column value with several other column values. These are the main comparison operators: BETWEEN: Tests whether a value is between a pair of values IN: Tests whether a value is in a list of values LIKE: Tests whether a value follows a certain pattern, as shown here: SQL> SELECT employee_id from employees WHERE dept LIKE 'FIN%';

The logical operators, also called Boolean operators, logically compare two or more values. The main logical operators are AND, OR, NOT, GE (greater than or equal to), and LE (less than or equal to). Here s an example that illustrates the use of some of the logical operators: SQL> SELECT last_name, city WHERE salary GT 100000 and LE 200000; When there are multiple operators within a single statement, you need rules of precedence. Oracle always evaluates arithmetical operations such as multiplication, division, addition, and subtraction before it evaluates conditions. The following is the order of precedence of operators in Oracle, with the most important first: =, !=, <, >, <=, >= IS NULL, LIKE, BETWEEN, IN, EXISTS NOT AND OR
The Set Operators
Sometimes your query may need to combine results from more than one SQL statement. In other words, you need to write a compound query. Set operators facilitate compound SQL queries. Here are the important Oracle set operators: UNION: The UNION operator combines the results of more than one SELECT statement after removing any duplicate rows. Oracle will sort the resulting set of data. Here s an example: SQL> SELECT emp_id FROM old_employees UNION SELECT emp_id FROM new_employees; UNION ALL: The UNION ALL operator is similar to UNION, but it doesn t remove the duplicate rows. Oracle doesn t sort the result set in this case, unlike the UNION operation. INTERSECTION: The INTERSECTION operator gets you the common values in two or more result sets derived from separate SELECT statements. The result set is distinct and sorted. MINUS: The MINUS operator returns the rows returned by the first query that aren t in the second query s results. The result set is distinct and sorted.
SQL Functions
Oracle functions manipulate data items and return a result, and built-in Oracle functions help you perform many transformations quickly, without your having to do any coding. In addition, you can build your own functions. Functions can be divided into several groups: single-row functions, aggregate functions, number and date functions, general and conditional functions, and analytical functions.
Single-Row Functions
Single-row functions are typically used to perform tasks such as converting a lowercase word to uppercase or vice versa, or replacing a portion of text in a row. Here are the main single-row functions used in Oracle:

CONCAT: The CONCAT function concatenates or puts together two or more character strings into one string. LENGTH: The LENGTH function gives you the length of a character string. LOWER: The LOWER function transforms uppercase letters into lowercase, as shown in the following example: SQL> SELECT LOWER('SHANNON ALAPATI') from dual; LOWER('SHANNONALAPATI') ----------------------shannon alapati SQL> SUBSTR: The SUBSTR function returns part of a string. INSTR: The INSTR function returns a number indicating where in a string a certain string value starts. LPAD: The LPAD function returns a string after padding it for a specified length on the left. RPAD: The RPAD function pads a string on the right side. TRIM: The TRIM function trims a character string. REPLACE: The REPLACE function replaces every occurrence of a specified string with a specified replacement string.
