ed GROUP_CONCAT() and an ORDER BY clause that named multiple columns could cause the server to exit. (Bug #16075310) * ORDER BY MATCH ... AGAINST could cause a server exit. (Bug #16073689) * When a partition is missing, code in ha_innodb.cc would retry 10 times and sleep for a microsecond each time while holding LOCK_open. The retry logic for partitioned tables was introduced as a fix for Bug#33349 but did not include a test case to validate it. This fix removes the retry logic for partitioned tables. If the problem reported in Bug#33349 reappears, a different solution will be explored. (Bug #15973904) * The mysql.server script exited with an error if the status command was executed with multiple servers running.

Re: compress/uncompress using java prepared statements
Hi,
I am a bit confused by the below, hope I can get some clarification.
In the database (mysql), I have image data stored in a blob. I can perform
operations like: COMPRESS and UNCOMPRESS on it and the data is fine.
Let's say I COMPRESS (ed) the data and then retrieve it use a SELECT
UNCOMPRESS(IMAGE_DATA) FROM , when I get this using jdbc
ResultSetMetaData rsmd = rs.getMetaData();
System.out.println("SHOW THE COLUMN TYPE: " + rsmd.getColumnType(1));
I am getting the Column type as
"VARCHAR<http://java.sun.com/j2se/1.4.2/docs/api/java/sql/Types.html#VARCHAR>",
whereas if I don't compress the data and do a straight SELECT IMAGE_DATA
..., the resulting
Column Type is a
"LONGVARBINARY<http://java.sun.com/j2se/1.4.2/docs/api/java/sql/Types.html#LONGVARBINARY>
".
Can somebody explain the above? Why does this work fine in the database but
I am not able to select the data into java properly?
How could I conver it into a proper format?
thanks,
Ramesh

Re: Bulk Upload.
Hello All, I have a strange situation while doing Bulk upload (using LOAD DATA FILE). I have a database which has 60 records, when I try to insert 1 more records it is taking around 50-55 seconds to complete the task (I feel this is much higher than the normal timings). I notice a strange thing that time taken to upload 1 records reduces to 10 to 12 sec after I run a big query (a query that needs full table scan) on that table. Can someone explain why this happens... I run MySQL 4.1.5 Gamma, on windows 2003 Server OS. Regards, Ramesh Confidentiality Notice: This transmittal is a confidential communication.

Hi Gleb,
The problem was with the JDBC Connect string, earlier it was;
jdbc:mysql://localhost:1/db1?useUnicode=true&characterEncoding=utf8
I changed that to:
jdbc:mysql://localhost:1/db1?useUnicode=true&characterEncoding=UTF-8

MySQL 4.1.3 Java/UTF8 support question
Hi,
In my.cnf, I have:
[mysql]
default-character-set=utf8
When I connect via mysql client and try to run a query which has a
"CONCAT" string function, it works fine and I get the proper output.
Example: SELECT CONCAT ('a', ' - ', 'b') = a-b
Now, I am trying to do make this work via Java and:
I use this JDBC Driver: mysql-connector-java-3.0.10-stable-bin.jar
Conn. String:
jdbc:mysql://localhost:1/db1?useUnicode=true&characterEncoding=utf8
I get the same error as I would have without the above
"default-character-set=utf8", i.e:
ERROR 1270 (HY000): Illegal mix of collations
(utf8_general_ci,IMPLICIT), (latin1_swedish_ci,COERCIBLE),
(utf8_general_ci,IMPLICIT) for operation 'concat'
How do I fix this, so that even the Java Client understands to use the
utf8 character set and I don't have to put the _utf8 in my sql
statement?
Appreciate your help.
thanks,
Ramesh

MySql SQL Help
Hi, Need a SQL/Design help. I have a table as follows: ORDER_HISTORY -- ORDER_ID | ORDER_NAME | ORDER_AMOUNT | ORDER_DATE -- 10 | Order 1| 20.00| 10-Jan-2003 11 | Order 2| 200.00 | 15-Jan-2003 12 | Order 3| 250.00 | 25-Jan-2003 13 | Order 4| 260.00 | 30-Mar-2003 14 | Order 5| 320.00 | 10-Jan-2004 I want to write a SQL which generates a weekly report from the ORDER_HISTORY table and shows it as: WEEKLY_DATE | CUMULATIVE AMOUNT -- 10-JAN-2003 | 20 17-JAN-2003 | 220 24-JAN-2003 | 220 31-JAN-2003 | 490 07-FEB-2003 | 490 Similarly another table without a Cumulative: WEEKLY_DATE | AMOUNT -- 10-JAN-2003 | 20 17-JAN-2003 | 200 24-JAN-2003 | 0 31-JAN-2003 | 250 07-FEB-2003 | 0 My thought process currently is to first get all the date intervals within the min and max dates of ORDER_DATE with a 1 WEEK addition to each min date and then for each of these intervals, I can then get the AMOUNT and add it to up to the previous amount if cumulative or just leave it if not cumulative. I am trying to find an elegant solution to implement this and not have too many trips to the database, i.e once to get each interval of date between the min and max and then for each interval go to the db again to get the amount. Is there any function which will return all the starting dates of each week between two dates? Appreciate any help or links to prior solutions or any book on this topic. thanks ___ Join Excite! - http://www.excite.com The most personalized portal on the Web! -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: jUDDI DataSource Connection Problem (Cannot create PoolableConnectionFactory)
Thanks to those that responded. The problem is solved there was a password mismatch between MySQL (what I had set up) and jUDDI. I changed the password in MySQL and it now works fine.

Hi Tore, Thank you so much. You are correct, I had duplicate records in the file. I haven't finish cleaning up the table. Once I finish cleaning and run the query and if I still duplicate, I will let you know. Till then, thank you so much for the answer.
