PostgreSQL – How to Escape an apostrophe(single quote) within a String

ByAdmin

You can escape a single quote (also known as an apostrophe) within a string by using another single quote. This is a common practice in SQL to handle single quotes within string literals. Here’s how you can do it:

To represent a single quote within a string, you can double the single quote character (''). Here’s an example:

INSERT INTO my_table (column_name) VALUES ('It''s a nice day');

In the example above, the single quote within the string is escaped by doubling it (''). When this string is inserted into the my_table table, it will be stored as “It’s a nice day”).

You can use this technique in SQL statements wherever you need to include single quotes within string literals, such as in INSERT, UPDATE, or SELECT statements.
