UPDATE SQL example 1

SQL UPDATE Example that updates the title and publisher fields of a table book. The following example is so simple that it doesn’t even use the WHERE statement to filter the records in the table.

UPDATE libro
SET titulo = 'ejemplos de sql update', editorial = 'srcodigofuente';

2nd Example UPDATE SQL

Query that updates the qualification and editorial of the table book just for the record with id 33:

UPDATE libro
SET titulo = 'ejemplo update', editorial = 'sql srcodigo'
WHERE id = 33;

This last example is very similar to the first but adding filtering using WHERE SQL to update only the chosen record.

3rd Example of UPDATE in SQL

Now I’m going to add a bit more complexity with a double condition and using the LIKE operator.

To be exact, in the following query I am going to perform the same task as example of previous update but with the condition that the books have to contain in the column theme the word “examples”. and the language is “Spanish” Also, this time the table will be called examples_sql_ebook

UPDATE ejemplos_sql_ebook
SET titulo = 'ejemplos de update en sql', editorial = 'srcodigofuente.com'
WHERE tematica LIKE '%ejemplos%' AND idioma = 'español';
