Hello Forum,

Could someone please send me the link and the names of the files to install
the version 7.4 in Windows 2000 server and XP Pro? I cannot discern the
files that one is supposed to download.

Thanks in advance for your response.

There is no version 7.4 yet. When it will be available, the release
announcement will contain instructions.

SELECT replace(data, '\'', '\'\'')
FROM temp_sales_lead
ORDER BY id, row LIMIT 10;

There was a bug in replace(), fixed by Tom in 7.3.3 I think (for sure by
7.3.4). If you have any embedded "%" characters in data, it would
trigger the bug. Try upgrading to 7.3.4.
