RE: question about converting isam to myisam tables (shortcut?)
Dave, Thanks for your response. The problem with that, while it is technically one insert statement, mySQL still builds the primary key record-by-record (keycache), rather than sorting the keys and creating the index in one shot, like myisamshk can do. INSERT... would take upwards of 24 hours to complete on my table of 18 million records, while myisamchk can do it in about 10 minutes. I know my method works, but I wanted to confirm that it was acceptable, and I wasn't missing anything serious. -Hank Instead of dropping down to OS cp commands, insert the data from table TBL_FLAT to TBL_INDX. INSERT INTO TBL_INDX SELECT * FROM TBL_FLAT; This will be valid in mysql. The insert will be fast since only one insert statement. Let the list know if this works for you. Or if your method is valid as well.

Hello all, I'm in the process of building a new mysql db server box to migrate a database off an existing web server. The webserver is running mysql 3.22.29, and the new box is running 3.23. The two biggest tables are about 20 million records and the data and index files are each just over 1GB, and each have a primary key and three or four non-unique indexes. I've copied the data files from the old box to the new, but when I use the ALTER TABLE...TYPE=MYISAM, it takes forever since it is rebuilding the indexes by keycache. So this is what I'm doing instead, and I'm asking if there are any problems associated with this approach: - the existing ISAM Table is called TBL_ISAM - Create a new/empty myisam table with no indexes named TBL_FLAT - Create a new/empty myisam table with all indexes named TBL_INDX mysql insert into TBL_FLAT select * from TBL_ISAM; (runs very quickly - not updating any indexes) mysql flush tables; the in the OS shell (linux) do the following: $ cp TBL_INDX.frm TBL_FLAT.frm $ cp TNL_INDX.MYI TBL_FLAT.MYI then to rebuild all the indexes via sorting, use myisamchk: $ myisamchk -r -q TBL_FLAT I'm left with a fully populated and indexed TBL_FLAT table, which seems to work perfectly as the original converted ISAM table. An in addition, I did first try myisamchk -r -k0 to disable the indexes and do the insert into the TBL_INDX table, but mysql still insists on building the primary key via the keycache - and it takes way too long. My method allows me to populate the data file with no indexes, and then fool mysql into rebuilding all the indexes at once via sorting. Does anyone think there are any risks/problems with this approach? Thanks in advance! -Hank __ Do You Yahoo!? Yahoo!

question about converting isam to myisam tables (shotcut!)

RE: question about converting isam to myisam tables (shotcut!)
Hank Instead of dropping down to OS cp commands, insert the data from table TBL_FLAT to TBL_INDX. INSERT INTO TBL_INDX SELECT * FROM TBL_FLAT; This will be valid in mysql. The insert will be fast since only one insert statement. Let the list know if this works for you. Or if your method is valid as well.

Conversion from ISAM to MYISAM table format
I'm in the process of converting all of my database tables from ISAM to MYISAM table format. I'll run the mysql_convert_table_format script which basically does an Alter table. If during this conversion someone accessed a web page which writes to the database (insert or update), what will happen? Will the affected tables become corrupt or will MySQL lock the table, perform the Alter, then unlock the table so the table can be inserted or updated?

ISAM v.s. MYISAM
Hi there I am working on a site where they are using ISAM files, (.ISM .IS1), I want to know if there is a way of accessing these from MYSQL? From what I have been able to tell they appear totally differently in comparison to some of my MYISAM table when I open them in Notepad.

RE: ISAM v.s. MYISAM
I'm working a project with the same exact scenario right now. My ver. of mySQL is 3.23.xx and my client's is 3.22.xx. there table sturcturing is ISAM and mine is myISAM. The only I've been able to transfer succesfully is by dumping all the data and re-importing on the clients end. -Original Message- From: Warren van der Merwe [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 15, 2001 7:27 AM To: [EMAIL PROTECTED] Subject: ISAM v.s.

ISAM to MYISAM
I've noticed that most of the really cool new features in MySQL use myisam tables. My tables are from an earlier version, and are only ISAM. 2 Questions: 1) How do you convert the tables? 2) Will my data be changed or corrupted by doing #1?
