Using where xxxx in (select ...... )
Hello, I have recently converted my Java Servlets to run against mySQL where previously I was using Microsoft Access. I use Tomcat and have swapped drivers etc and everything works fine, more or less. However, I have one big problem which is as follows :- My servlet software dynamically builds SQL of the following form, which to my knowledge is fairly standard :- - Query is: select * from service where ((primary_category in (select sub_category from category where sport = 1 ))); java.sql.SQLException: Syntax error or access violation: You have an error in yo ur SQL syntax near 'select sub_category from category where sport = 1 )))' at li ne 1 - The text above is copied directly from some diagnostics on my Tomcat console. If I use exactly the same query from phpMyAdmin I get exactly the same error so it's not my JDBC driver that's at fault. Why won't mySQL let me use this construct ? Many thanks. Jon Green.
