使用mysql UPDATE插入换行符

Question

im using JSON.stringify and my stringified variable is:

{"ops":[{"insert":"drfsdfgg sdfg sdg \ns\ndfg\ndf\nsg\nsdfg\n"}]}

But when I do an UPDATE, the data is like that in mysql database:

 {"ops":[{"insert":"drfsdfgg sdfg sdg s dfg df sg sdfg "}]} 

I would like preserve all \\n like the INSERT! ( yes INSERT WORKS )

the SQL query:

  connection.query("UPDATE products SET description ='" + req.body.description + "' WHERE id = " + req.body.id, function (error, results, fields) { if (!!error) { console.log('erreur'); } else { // console.log(results); res.json(); }; }); 

Answer 1

I found the solution, all is about the SQL syntax. Thank you so much to me and my brain power.

  connection.query("UPDATE products SET description = ? WHERE id = " + req.body.id, [req.body.description], function (error, results, fields) { if (!!error) { console.log('erreur'); } else { // console.log(results); res.json(); }; });
