ALTERing a table with a CREATE TABLE statement????
Hi, I wrote a software generating a statistical database. That database keeps time series. What I am doing is - looking at the data file and get the channel names. - CREATE TABLE IF NOT EXISTS IF Database exits I want to ALTER the table but only add new coloums that are new. Is there a way to alter table with a create statement. What I mean is I will again generate a CREATE TABLE structure and than check the existing table if the coloums are match and add the new ones at once. Maybe there is such a command in mysql like ALTER TABLE table_name1 with CREATE TABLE table_name2; is there? if ot what do you advice me to do, in an easiest way?

VS.NET C++ and MySQL
Hi, I know this is not the exact topic of the list but I am sure some people from this list spend some time on it. I am new to VC++ but getting better indeed. I need help on how to connect to MySQL server. I need a connector and an example. It must be free because this is a student project :) So far, I have tried http://myweb.hinet.net/home4/s630417/ (Code Lib .NET) but it only supports 4.1 or above. I do not want to upgrade and you all know why. Here is my box info: - Microsoft Development Enviroment 2003 version 7.1.3088 - Microsoft.NET Framework 1.1 version 1.1.4322 SP1 - Windows 2000 Professional - MySQL v4.0.22 - MyODBC 3.51.10 (which is not working very well I do not know why so I prefer File DSN if ODBC is needed. If any body point me to a free tool or an example that would be very nice.

[solved] Re: LOAD DATA INFILE question...
Hi Patrick,
I was doing that it was taking 20 seconds to chop the fields from the file.
That was the problem.
Meanwhile about my problem I have seen that the lines in data files end with
\r\n not \n so it solved the problem.
Now it takes 3 seconds to dump the file and chop the necassary fields.
thanks to MySQL.
:)
thank yo again for answer...

I think it would be simpler to pre-process the file using cut with the
appropriate delmiter if it's not tab-delimited already. Then import
the reduced file.

big table, slow queries...???
Hi, I am new at this group. Nowadays I am using PHP/MySQL more than ever. I have a problem with making queries on my huge database (totally more than 20 million rows and 9 GB). The main problem is it is rather slow. For example I am making a query which is checking the 5 biggest tables for, from 2 where options to 20. I am using something like that; SELECT table1.field1, table1.field2, table1.field3, table2.field2, table3.field2, table4.field1, table5.field1, table5.field2 FROM table1, table2, table3, table4, table5 WHERE (table1.field1=table2.field1) AND (table3.field4 BETWEEN case1 AND case2) (Where statement is longer than this) and so on. I think you understand the structure I use for making queries. But it is too slow. I mean I was expecting to be faster. Can you advice me a different kind of query string? I read some articles about using JOIN, GROUP or so on. But I am little bit confused about it. What is the best way to make queries on big table? Thanks, FERHAT P.s : I am using MySQL 3.23 and PHP/Apache on a Windows XP machine. 386 MB RAM with Pentium3 350.

Re: big table, slow queries...???
Tore, Yes, it is necasarry to pick up all the values from 5 tables. I made indexes for each table. My queries are between 12 to 26 seconds now. I am generating a WHERE statement before make the query. If the user do not enter the some min and max values I am skipping this WHERE statements. The interesting thing is (for me) when I enter lots of limits for lots of input values query is faster. When I just select a country for example the query is slower. I mean lets say that speed field is between 10 and 40 and I want to chose a country. if I enter 10 and 40 for range and chose country it takes 12 seconds but if I do not enter speed range (as you see to enter or not is getting the same result) and choose a country it is 18 seconds. The main reason I asked this to the group is the same query was faster on interbase server. Than a question come to my mind is interbase server is faster in such huge queries? if so WHY? Cause on MySQL the simple queries are faster. As I said I am using MySQL 3.23 PHP Apache on WinXP. Does it help if I upgrade to MySQL 4.0 or is this come from XP... I am just trying to figure out if it is (much much) better to use Linux?
