Re: How 'if not exists' implemented in MySQL?
First, please be aware that MySQL 5.0 is an alpha release. It is very young and there may still be some unresolved issues. It is not generally recommended to use alpha releases in production situations. Besides, anything that can be done in a stored procedure can be implemented in client side code. That said, the If Exists is used with Create and Drop statements. I don't think that you can use it to determine the rows returned by a select statement. There may be other techniques but this is what I'd do: Take your select query any convert it to a count(*) query and use Select Into to store the count in a variable. Use this variable in your if statement. See this chapter in Select Into: http://www.mysql.com/doc/en/SELECT_INTO_Statement.html If it isn't possible to turn your query into a count(*) then you might try using FOUND_ROWS().

Re: When does using multiple databases make sense?
In our accounting software our users can manage the books for several different companies with the same program. As such I have to keep a field (in every record) that designates which company the given record is for and use it for report filtering, lookups, etc. Had I used a different database for each company then I would not need the overhead of this field. We chose the company field over the multiple databases because many of our clients are vertically integrated and do cross charging (an entry from one company posts to another company). This inter-company stuff is easy if the data is all in one database but we always have to remember to filter by the company field everywhere else.

Re: Bet the Business
I'm lead developer for a company that writes custom software for the mining industry. We support MSSQL and MySQL. I've found that from a programming aspect (VB + ADO) there is relatively little difference between MSSQL and MySQL. There is some sight syntax differences and MySQL versions 5.0 do not support stored procedures. We use the InnoDB table type for MySQL as it provides row level locking and transactions. Our largest client has about 1 gig of data and averages 125 users. I've found that MySQL usually out performs MSSQL if you tune it properly and use good programming techniques. It is less integrated with Microsoft products though so if your clients will be accessing the data via MS Office applications then MSSQL will seem easier. We offer both platforms mainly because a lot of IT managers are convinced that Microsoft solutions are the best even when benchmarks say different. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Bet the Business
soapbox Back to stored procedures for a second. I use them with MSSQL. For certain tasks they greatly improve performance because I don't have to move all the data client side. For the vast majority of tasks though stored procedures yeild little performance gain. I've seen systems that (designed as Microsoft suggests) wrapped all SQL usage in stored procedures. This is nonsense. Also, stored procedure have two very important liabilities: they break the n-tier model and they expose source code to the customer (if you sell your app). If you change your back end then you get to re-write all your stored procedures (I had to do this once). I routinely get calls from IT managers who have looked at my stored procedures and have questioned why I did so and so. This forces me to research it and come up with a reasonable answer. In my opinion the performance gain of stored procedures are rarely worth the headaches so their lack of them in MySQL is really not a problem. Will I use them in MySQL 5.0?

Re: Load Data Local Infile problem
This is from the manual. See the 3rd paragraph. The REPLACE and IGNORE keywords control handling of input records that duplicate existing records on unique key values. If you specify REPLACE, input rows replace existing rows (in other words rows that has the same value for a primary or unique index as an existing row). See section 6.4.7 REPLACE Syntax. If you specify IGNORE, input rows that duplicate an existing row on a unique key value are skipped. If you don't specify either option, the behavior depends on whether or not the LOCAL keyword is specified. Without LOCAL, an error occurs when a duplicate key value is found, and the rest of the text file is ignored. With LOCAL, the default behavior is the same as if IGNORE is specified; this is because the server has no way to stop transmission of the file in the middle of the operation. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
