To test whether a value is NULL, use IF value IS NULL, as in these examples: 1.1 Variable Initialized to NULL by Default In this example, the variable counter has the initial value NULL, by default. The example uses the "IS [NOT] NULL Operator" to show that NULL is different from ze...
In stream input examples, lines beginning with h (such as h 3800) are heartbeat input tuples. These inform Oracle Event Processing that no further input will have a timestamp lesser than the heartbeat value. Example 4-6 S [range T] Query <query id="q1"><![CDATA[ SELECT * FROM S ...
Let’s have a look at the records in the customers_jan and customers_dec table. So that later, we can understand how set operations are helpful. A schema for the discussed tables is as follows: customers_jan: customers_dec: Types of SQL Set Operators with Examples ...

Another conditional operator is ?:, which can be thought of as shorthand for an if-then-else statement (discussed in the Control Flow Statements section of this lesson). This operator is also known as the ternary operator because it uses three operands. In the following example, this operator...
As you can see in the preceding examples, data stored in an Oracle database (SQL*Plus) is case sensitive, whereas the MySQL example demonstrates the opposite. Most companies prefer to store data in uppercase to provide data consistency. I recommend that you always store data either in all ...
(This does not apply to such literals if they are written with a _binary introducer, BINARY operator, or other way of specifying them explicitly as binary strings.) Examples: These bit operations evaluate the literals in numeric context and produce a BIGINT result: b'0001' | b'0010' ...
