Question

I’m trying to execute the following query via php’s mysql_query function but it’s not working.

When I execute it directly (via phpMyAdmin’s sql tab) it does work. Any idea what’s going on?

Update t1 SET r ='[{"Ia":36.009,"Ja":-78.93},{"Ia":36.01,"Ja":-78.93}]' WHERE id=1

Thanks!

It depends on how you use it. You have to escape your quotes. So it should be :

mysql_query('Update t1 SET r =\'[{"Ia":36.009,"Ja":-78.93},{"Ia":36.01,"Ja":-78.93}]\' WHERE id=1');

OR

mysql_query("Update t1 SET r ='[{\"Ia\":36.009,\"Ja\":-78.93},{\"Ia\":36.01,\"Ja\":-78.93}]' WHERE id=1");

Anyway, that is not pretty safe. You should have a look over prepared statements, PDO, MySQLi .

Standard mysql is old and lacks of lots of features.

Hope this helps.
