Re: MySQL question
select day(`timestamp`) as dayOfMonth, count(`timestamp`) as searchesPerDay from mytable where `timestamp` between '2012-05-01 00:00:00' and '2012-05-31 23:59:59') group by dayOfMonth order by dayOfMonth asc iirc, timestamp is a reserved word in MySQL - hence it's enclosed in ticks above (note that ticks are NOT single quotes). MySQL also allows you to use column aliases in group by and order by statements. On Tue, May 8, 2012 at 3:57 AM, Che Vilnonis wrote: > > Should be a simple one for a mysql guru.

Re: MySQL date problem
can you perform any date functions on it at all ?
Try running it through CreateDate() or CreateODBCDate() first and see if
that helps

Re: MySQL date problem
Nevermind. Stupid mistake. I was looping over a number of records and it turns
out that one of the records had a null value set which was what caused the
error. Had nothing to do with MySQL dates at all. Ugh.

Re: MySQL install
You should real the notes on the various install modes/settings to make sure you install it configured with the best options for your needs, it isn't really as straight forward as MSSQL. I would suggest you block remote access to mysql in your firewall and use phpmyadmin to access it or just login to the server and use the tools from there. To setup a DataSource, in the dropdown list for database type, instead of selecting "MSSQL" or "Access" you choose "mysql 4/5" On Mon, May 16, 2011 at 6:02 PM, Ken Hammond wrote: > > As suggested by Raymond, I am going to install MySQL server.

Re: MySQL Conversion
Yes mysql has a 4gb limit, for MSSQL there is also a limit of 10GB, please see this url http://www.microsoft.com/sqlserver/2008/en/us/editions-compare.aspx <http://www.microsoft.com/sqlserver/2008/en/us/editions-compare.aspx> which is more than enough for most people. In fact we have been hosting SQL Server express since 2005, which did have a 4GB limit also, and no-one EVER came close to exceeding this. In fact the average databases are only a few hundred mb in size, so it really is not a problem. MySQL and MySQL also has limitations which require you to purchase the enterprise editions. But as with MSSQL express, these limitations do not affect your average user with a website and a database. If you need an enterprise solution, expect to pay for it. The very fact that you are upgrading from MSACCESS should really tell you that your database requirements are quite simple, so the limitations are unlikely to affects you. What I will say is that we have been hosting MSSQL for 10+ years (since MSSQL 2000) without any major issues and is pretty trouble free. We have been hosting mysql since v4 and some customers regularly have issues with tables getting corrupted (common issue), performance issues where 1 database can cause mysql to consume 100% cpu, row locking issues etc and certainly requires a lot more support, tweaking and trouble shooting. Clearly I have a preference for MSSQL, but issues like the above also lead me to generally recommend MSSQL over MySQL for anyone on windows, especially when both are free. You also need to make sure you understand the difference with the MySQL storage engines (MyISAM, INNODB) and use the appropriate one, otherwise this can cause many performance issues as well. You don't have any such issue with MSSQL, there are no different storage engines to learn, MSSQL pretty much just handles everything for you. The GUI tools that come with MSSQL also give you a lot more control out of the box, most people resort to using PHPMyAdmin instead for mysql, which is a web based tool. There are other free mysql GUI's. but in my experience to get the same level of features or control you really need to buy a copy of a commercial product like Navicat or similar. I think the overall biggest thing that makes a difference for me is backups. With MSSQL it is easy, setup a scheduled maintenance plan via the GUI to backup your database and also perform various tasks, such as optimise imdexes, shrink database, and much more. The backups whether done manually or scheduled are created very quick and are a single file which can be restored in seconds. In case of disaster a raw MSSQL database can also be copied to another server and attached. With MySQL (up to v5) you have to create a DUMP file of the entire database as SQL statements which re-insert the data. It is pretty clunky to say the least and can take hours to create or restore a dump if you have a large database. However you can at least do it via PHPMyAdmin or remote tools and save the dump locally. This is however the only way you can restore a MySQL database, if you backup the raw files, you cannot do much with them without a lot of hassle.

Re: MySQL Conversion
You would probably find it easier to upgrade to MSSQL, which is better anyway in so many ways than MySQL esp if you are on windows (speed, performance, reliability, scheduled backups, automated maintenance, no table corrupting issues, no horrid SQL dumps to name a few). Presumably if your using Access you must be on a windows host, so MSSQL is probably available to you.

Re: MySQL Conversion
how are you migrating your db? mysql used to have a migration toolkit as part of mysql gui tools bundle which handled access->mysql migration very well. the gui tools have now been replaced by mysql workbench, but you can still download them from mysql website. gui tools: http://dev.mysql.com/downloads/gui-tools/5.0.html workbench: http://dev.mysql.com/downloads/workbench/5.2.html mysql equivalent of access's autonumber type is an Integer column with auto_increment attribute. http://dev.mysql.com/doc/refman/5.5/en/numeric-types.html (bottom of page for auto_increment attr info) you can also set/change the next auto_increment value to use on mysql column: ALTER TABLE t2 AUTO_INCREMENT = value (from http://dev.mysql.com/doc/refman/5.5/en/alter-table.html) all this and much much more is covered in mysql reference manual on mysql website: http://dev.mysql.com/doc/ another point to keep in mind: if you cfqueries used any access-specific syntax you will have to re-write them to use proper sql to work with mysql db.

Re: MySQL Conversion
If you have no gaps in the autoid field in Access, you can create am additional field in MySQL for your Access ID, and order the Access table in ID order, then import it and the MYSQL autonumber field should match the Access ID field. if that is the case, you can then delete the extra field. If you have gaps and id is an essential data element that has relational children, it's a much more complex problem. If that is the case, let me know and I'll try to explain how to do it.

Is that correct? > It's not as simple as you think it is. I don't know the answer for sure but this is what I know. Assuming mySQL...How much space something takes is dependent on the type of engine you select. The common ones are innodb, myISAM, and the perconaDB. As far I remember the innodb takes more space because it has more features and can't be compressed. Looking at myISAM, which by the way is probably not the engine you want for any transaction based db, you would use one (1) more bytes over a varchar(1000). So if storing i piece of data as a varchar(1000) that was 299 cahr longs it would take 300 bytes it would take 301 bytes if you had typed is as a text. That is true up to 65536 bytes. then the storage requirements changes. recap: in your case if you were using myISAM the text type would use 1 more byte than the varchar(1000). Things like char encoding like UTF or latin will impact it as well. ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:336810 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: mySQL data types - possible db bloat with text type? yes or no?
With MSSQL you are limited to about 8000 bytes per row and anything beyond this will be chopped, so you need to be careful how much data you are storing. Using BLOBS will overcome this as a pointer to the blog is the only thing stored in the row, and the blog is actually stored separately. Using datatypes of specific lengths does indeed only take up the space used, but other factors affect thr storage such as page sizes. This paging applies to mysql as well, but I have never looked too deeply into it as I find MySQL very flaky and poor in performance compared to MSSQL so only use it when I have to, such as when I am using PHP apps.. I think this site will help you though., here is a post specifically about page sizes, but check the rest of the site too. http://www.mysqlperformanceblog.com/2006/06/04/innodb-page-size/ You also need to make sure you are using the correct table type (MYISAM or INNODB) -- Russ Michaels www.cfmldeveloper.com - Supporting the CF community since 1999 FREE ColdFusion/Railo hosting for developers. blog: www.michaels.me.uk ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:336809 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Well, I guess that's the problem. I was certain there was a cf_sql_datetime (and pretty certain I've been using it for years :) ). I guess I'd expect CF to throw an error for an invalid sql type.

Well, it looks like I can leave the field as a datetime but just use

I'd still like to know if there's a better way, but it's a lot easier to

First, that is in fact an invalid date/time value. Valid date/time values resolve to an actual date/time. Second, the general approach to handling this sort of problem is to explicitly pass NULLs to the database if you don't have a corresponding actual value. So, if someone leaves a field blank, you send NULL instead of an empty string, etc. If you're using CFQUERYPARAM (as you certainly should be unless you're using stored procedures) you can use the NULL attribute with a Boolean expression that resolves to true if the field is empty: Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ Fig Leaf Software provides the highest caliber vendor-authorized instruction at our training centers in Washington DC, Atlanta, Chicago, Baltimore, Northern Virginia, or on-site at your location.

Re: MySQL Auto Increment Field
While I agree that SCOPE_IDENTITY is the preferred syntax, it's
unlikely that you'll encounter a problem with @@IDENTITY. CF will use
a single connection for all queries within a page that use the same
datasource, username and password, and the queries will be executed
sequentially unless wrapped in CFTHREAD. So to run into this problem,
you'd have to have a single query doing multiple inserts in a nested
transaction or stored procedure call.
In summary, I would write new T-SQL with SCOPE_IDENTITY, but I
wouldn't bother rewriting existing code.

RE: MySQL Auto Increment Field
Man. Now I'm glad I posted that. Just went through and changed all: SELECT @@Identity AS newId To SELECT SCOPE_IDENTITY() AS newId Looks like it worked.

Re: MySQL Auto Increment Field
And for those folks using MSSQL, please note that @@IDENTITY is
probably not what you want either. @@IDENTITY returns the last
identity produced by a connection to the database, regardless of the
table. So in some circumstances you can end up with an identity
returned that is not from the table you just inserted into. In most
cases you'll instead want to use SCOPE_IDENTITY() which returns the
identity produced by the current connection and current statement
combination.
For more, you can read up here: http://bit.ly/rhkvf

The @@IDENTITY global variable is not standard SQL. It's specific to
T-SQL. So is SET NOCOUNT ON|OFF. Of the four SQL statements you've

The only way I found to fix this is to return the first query via MySQL then use a Query of a Query in CF to do a group by on the data and ORDER it by the DateTime field. Strange.

Charlie! That app is AWESOME. EXACTLY what I was looking for. Better windowing, much more attractive, smart shortcuts, inline quick querier. So slick. Command 1 2 3. So simple and clever. There's even a keyboard shortcut to execute your inline query ( though it's a weird one: Fn + Enter ). Seriously thanks a million.

Re: MySQL IDE on OS X
You know, I use the MySQL Query Browser on Vista a lot and actually love it. On OS X however, that app literally crashes on me within 30 seconds of launching it each and every time, and I've got a completely fresh install of OS X as of Saturday night with just CS4, Adium, some browsers, ColdFusion and MySQL installed. Is it stable for you? Thanks.

Also depending on your traffic versus how often the products will get updated versus your hosting plan etc you may want to output the entire tree at the time of it being maintained on the back end rather than every time someone visits the site.

Re: MySQL - How to create a category tree in a store
I am assuming you at least have product_id and category_id in your linking table. I think if you added a parent_id accounting for the root level you could build out your tree. Not sure of how you want to go about it but thinking out loud: 1. Query all categories at root level 2. Loop through root level and pull children (all those with a parent as that category) 3. Repeat this for the max levels 4. Pull products at each level (1,2,3,4) Basically you are only assigning one sub/category but you have the hierarchical relationship stored in the db. You would have to account for that when searching on the front end. Front end I would suggest jQuery for an accordion like effect(slidedown/up and/or fadein/out) and pull the products using the ajax or load method. -- Ryan On Fri, May 22, 2009 at 10:41 AM, Will Tomlinson wrote: > > >@willr u ok with setting a maximum number of levels? > > > >-- > >Ryan > > > > Yep.

Re: MySQL and CF LAST_INSERT_ID()
InnoDB are the only transactional tables in MySQL, but CF doesn't know
about the backing table, and the latter is what we care about. In
order for transactions to work correctly, the client has to ensure
that all queries within the transaction execute on a single DB
connection, and that no other queries are executed on that same
connection. Since connections are managed by CF's connection pool,
using the CFTRANSACTION tag ensures that "i own the connection"
behaviour, regardless of whether the backing DB is actually
transaction-aware. That's the part that is essential for a
LAST_INSERT_ID() query to execute correctly, not an actual
transaction.
And I know about the MySQL server setting for multiple statement
support, but I'm of the opinion that you should never use it. :)
Aside from the potential SQL injection vulnerabilities, I find that
grouping statements in CFQUERY tags (as you can do with MSSQL out of
the box), usually ends up in code that is harder to follow, because
the eye naturally uses the CFQUERY tags to delimit blocks, not CFQUERY
tags AND internally contained semicolons.

Re: MySQL and CF LAST_INSERT_ID()
well...
first, the proper syntax for an INSERT query starts with INSERT INTO,
not just INSERT ...
second, by default, multiple statements are NOT supported in mysql db -
do you have multiple statements enabled for this dsn in mysql?
third: cf8 has a cfquery attribute RESULT, which, when utilised
properly, can return the new generated PK. check the cfml reference for
details. if you do not have one - download a free pdf from adobe.com.
for mysql db the variable is GENERATED_KEY...

Re: MySQL and CF LAST_INSERT_ID()
You actually *can* run multiple statements in a cfquery if you change a
setting in the datasource. By default MySQL does not let you, this is a
security precaution to protect against SQL injection. This may help:
http://www.petefreitag.com/item/357.cfm
Also note that you can only use CFTRANSACTION with innodb tables, not
MyISAM tables. I don't know if it will throw an error or not, last time
I tried it did not, but there is no transaction going on when you use
these tags with MyISAM tables.

Re: MySQL and CF LAST_INSERT_ID()
It doesn't work because you can't run multiple statements in a single
query. If you use two CFQUERY tags (wrapped in a CFTRANSACTION to
ensure connection affinity) it'll work fine. MySQL Front is splitting
the single query into two distinct queries on the semicolon, sending
each to the server independently, and then giving you back the two
results. I.e. it's a client-side optimization, not server
functionality.

Re: MySQL - Trying to query x days back
I would use the DATEDIFF() function: SELECT DATE(orderdate) AS thedate, SUM(ordertotal) AS ordersubtotal FROM tblOrders WHERE DATEDIFF(current_date(), orderdate) <= 30 GROUP BY DATE(orderdate) (I think this should work; I use MSSQL, so can't test this...)

Re: MySQL 5 TIME columns reported as dates in ColdFusion 8
CF doesn't have the concept of a time data type. When I need
durations, I always store a number of seconds (or milliseconds). I've
used TIME columns a couple times, usually for external reasons, but
all my queries that feed CF convert the time to a number of seconds.
