How to Properly Escape Single Quotes in MySQL Strings?

How to Handle Single Quotes in MySQL Strings

When inserting values into a MySQL database that contain single or double quotes, these characters can cause issues. To resolve this, it is necessary to escape these characters to allow for proper data insertion.

Escaping Single Quotes

To escape single quotes, one can use two consecutive single quotes within the string:

SELECT 'This is Ashok''s Pen.';

By doubling the single quote, it is interpreted as a literal character within the string, avoiding conflict with the closing delimiter.

Alternative Method: Using Escape Sequences

Another option is to use the backslash character () before the single quote to escape it:

SELECT 'This is Ashok\'s Pen.';

This method also ensures that the single quote is treated as part of the string rather than as a delimiter.

Example

Consider the following value:

This is Ashok's Pen.

To insert this value properly into a MySQL database, it can be escaped using either of the aforementioned methods:

• Double Single Quotes: 'This is Ashok''s Pen.';
• Escape Sequence: 'This is Ashok's Pen.';

By employing these techniques, you can effectively handle single quotes within MySQL strings and ensure accurate data insertion.
