How to Escape the Ampersand (&) Character in SQL Search Queries?

Escape ampersand character in SQL string

Question:

The ampersand (&) character cannot be escaped in a SQL query that searches for rows whose names contain this character.

Problem Solved:

The provided query attempts to escape the ampersand with a backslash () but does not work for unknown reasons.

Solution 1:

Don’t use the ampersand character in a string, use its ASCII code instead. This ensures that it is interpreted as a string value rather than special characters.

<code class="language-sql">node_name = 'Geometric Vectors ' || chr(38) || ' Matrices'</code>

Solution 2:

Alternatively, use the LIKE operator to search for a string containing the ampersand character represented by an underscore (_). This reduces the likelihood of matching other records that differ only by the sign character.

<code class="language-sql">node_name LIKE 'Geometric Vectors _ Matrices'</code>
