I apologize for asking this question.
I am somewhat confused by Microsoft's Licensing and I personally can not
justify to senior management why
MS SQL should be procured instead of procuring software more urgent
requirements.
I had the not so bright idea that maybe a MS SQL emulator or
I have a table:
Id |path1 | display| value
1 | ostype | os|windows
1 | ostype | ver |NT4
2 | ostype | os | linux
2 | ostype | ver | RHEL 5.4
That I would like to tranform into
Id | os| ver
1 |windows | NT4
2| linux |RHEL 5.4
Thank you,

I've got a similar setup, total records across about 8 tables hoovers
Problem: I use two applications one called snort, the client that
inserts data into eleven(11) tables.
The other application BASE joins the tables into one table. When the
tables become 4GB in size,
deleting records for one month becomes unbearably slow(20-30days). The
search(Select ) is slow
Now, I when I do a desc on data table, I get the error
ERROR 1016 (HY000): Can't open file: 'data.MYI' (errorno: 144).
As I recall I ran:
optimize data;
The Optimize command did not complete the error as I recall was /var
filesystem full.
Running the following commands:
ls data.*
data.MYD

Hmmm. Doesn't look pretty
When I try to retrieve all rows in the event table that are in a
particular range and then
try to determine if the cid is in the data table the join takes
forever.
So I tried just tried adding the table to see if the where clause was
slowing things down. Below is a portion on my session.
Could the problem the Locked data table in this case?
mysql show processlist;
+-+---+---+---+-+---
-+--+---
---+
| Id | User | Host
It appears that every time I start query the event or the data table
gets Locked.
Could this have any affect on why it takes so long to delete records.
Grasping at straws,

I was definitely on the wrong track on this one.
I annotated your commands to make sure that I understood what they
were doing. Are my comments correct?

You have the wrong syntax. You can't mention a table in the WHERE
clause that wasn't in the FROM clause. Try

Oops, left out an important part. You should change the Avg_row_length

ALTER TABLE AVG_ROW_LENGTH = 50
You need to specify an average row length if you have dynamic length

After a 23days of running mysql, I have a 3GB database. When I use an

called base(v.1.2.2) a web based intrusion detection analysis console, the

I have three(3) instances of an application inserting data into a MYSQL (4.X)

Does such a JOIN exist that can create a pivot table?

How does one insert records based on some kind of meta data or key in
particular table belonging to a merge table?
I have a network logging program and would like to partition the table so that
analysts can query certain tables belonging
to the merge table instead of the whold table to corelate
Firstly,
I do appologize for my ignorance in advance. I read the message regarding PRODUCT()
