<h2>Using Quotes</h2>
<p>Note that we have used single quotes around the conditional values in the
examples.</p>
<p>SQL uses single quotes around text values (most database systems will
also accept double quotes). Numeric values should not be enclosed in quotes.</p>
<p>For text values:</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td><pre>This is correct:
SELECT * FROM Persons WHERE FirstName='Tove'</pre><pre>This is wrong:
SELECT * FROM Persons WHERE FirstName=Tove</pre></td>
</tr>
</table>
<p>For numeric values:</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td><pre>This is correct:
SELECT * FROM Persons WHERE Year>1965</pre><pre>This is wrong:
SELECT * FROM Persons WHERE Year>'1965'</pre></td>
</tr>
</table>
<br />
<hr />
<h2>The LIKE Condition
</h2>
<p>The LIKE condition is used to specify a search for a pattern in a column.
</p>
<h3>Syntax</h3>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td><pre>SELECT column FROM table
WHERE column LIKE pattern</pre></td>
</tr>
</table>
<p>A "%" sign can be used to define wildcards (missing letters in the
pattern) both before and after the pattern.</p>
<hr />
<h2>Using LIKE</h2>
<p>The following SQL statement will return persons with first names that start with an
'O':</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td><pre>SELECT * FROM Persons
WHERE FirstName LIKE 'O%'</pre></td>
</tr>
</table>
<p>The following SQL statement will return persons with first names that end with an 'a':</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td><pre>SELECT * FROM Persons
WHERE FirstName LIKE '%a'</pre></td>
</tr>
</table>
<p>
The following SQL statement will return persons with first names that contain the
pattern 'la':</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td><pre>SELECT * FROM Persons
WHERE FirstName LIKE '%la%'</pre></td>
</tr>
