RE: Considering migration from MyISAM to InnoDB
Thank you. I know how to migrate tables using ALTER TABLE - my question has more to do with *whether* I should migrate. For smaller databases (10mb in size) is it really beneficial?

SET question - @ or @@?
While I was RTFM to find out how long SET variables last, I noticed that my book uses @@VarName but the sample code I'm using has @ VarName. I didn't see a reference to the single @ in the SET section of my book. So, what is the difference between @@ and @? Thank you.
SELECT rows from the previous business day
A table exists with id and datetime columns; I need to SELECT records from the previous business day. I began with this: SELECT id FROM table WHERE TO_DAYS(NOW()) - TO_DAYS(datetime) =1 But if NOW() is a Monday, it pulls records from Sunday (there are none since records are inserted M-F only).I thought of using something like this in my WHERE clause: AND DAYOFWEEK(datetime) != 6 Though this doesn't seem like an operable solution (If I'm not mistaken this would return 0 rows if no records were inserted on a Sunday). Does MySQL include a specifier for business day? Thank you, Michael
SELECT assistance
I have a table containing three columns: Int intint ++-++ | id | serialbegin | serialend | ++-++ | 1 | 10 | 20 | ++-++ And say we have serial number 11. Is there a way to SELECT any rows where $my_serial is greater than/equal to serialbegin and less than/equal to serialend? I tried this query: SELECT id FROM numbers WHERE serialbegin = '11' AND serialend = '11'; Empty set (0.00 sec) Is this a little more complicated than I'm making it out to be (or am I missing something obvious)?

Illegal mix of collations - new twist on a familiar problem...
When running this simple query: SELECT fileid FROM test WHERE ecn='0' MySQL yields this error: #1267 - Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation '=' The table collation is latin1_swedish_ci. I ran SHOW CREATE TABLE fileid and found this: DEFAULT CHARSET=latin1 at the end. Here is the table layout: fileid int(10) datereceiveddate scn varchar(11) latin1_swedish_ci ecn varchar(11) latin1_swedish_ci Here is the problem: The table collation was once utf8_general_ci (due to mistake), it was switched back to latin1_swedish_ci.

Upgrading bundled ver of mysql included with php 4.3.1
What steps are needed to upgrade (or remove) the builtin mysql [3.23.49] included with php 4.3.1 source? I have mysql 4.x installed and working by itself, but php continues to use 3.23.49. I have tried recompiling php 4.3.1 without --with-mysql on the configure line. Doing so did not remove the builtin 3.23.49 package. Any tips?

Phpinfo() returns MySQL Version 3.23 from a php script. Client API version 3.23.49 MYSQL_MODULE_TYPE builtin MYSQL_SOCKET/var/lib/mysql/mysql.sock MYSQL_INCLUDE no value MYSQL_LIBS no value However, issuing 'mysql -V' at the command line returns version 4.0.1.

So I assume the version of MySQL bundled with PHP 4.3.1 is in fact 3.23.49 and this is overriding my standalone installation. It's not overriding anything, it's doing what you asked: in your configure you told PHP to use its built-in (MYSQL_MODULE_TYPE) MySQL support. Without recompiling, is there a way to upgrade the bundled client? No - I believe you need to recompile PHP (this path assumes an RPM installation of MySQL): Yes, MySQL is installed via RPM. So, when I recompile PHP I should leave -off- the '--with-mysql' configuration option altogether? If yes, how does PHP know MySQL exists on the system, or is this handled automatically behind the scenes? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
SELECT a percentage range of a given value
Hello, I have a music database containing song BPM (Beats Per Minute) data values stored as FLOAT. I need to pull a range of BPM values based on a user-supplied integer. The range should pull all records which are 8% higher and lower than the given integer. I tried this query for starters: SELECT * FROM test HAVING ( bpm SUM(100 * 1.08) ) OR ( bpm SUM(100 * .92) ) No errors appeared however only one row returned (with bpm value 55.03). There are approximately 100 records that have a bpm value between 92.00 and 108.00 in the test database. Am I overlooking something obvious?

MySQL Gamma 4.0 - safe for production?
I've been researching the possibilities of upgrading from MySQL 3.23 to 4.0 and have read opinions supporting why I should stay with what I have, upgrade, or move to another DB altogether. I thought it would be in my best interests to ask this list the same question. I'm not interested in migrating to a new database platform, however I am still interested in possibly upgrading what I have. My reasons for wanting to upgrade are related to enhanced FULLTEXT searching features with the Gamma version. Would 4.0 be reasonably safe for production? - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

The ticketid is the key I use across several tables. It is a field in call_notes and that is how I'm getting the noteid (which is the primary key of call_notes and call_notes_text).
