Does MySQL (4.0.20-standard) Allow Subqueries???


Im moving a development app (MySQL 5.0) to a different server which runs MySQL 4.0.20-standard. I am getting errors on queries that have subqueries such as...

SELECT id
FROM table1
WHERE id IN (
SELECT id FROM table1
)

Seems like such a simple query but it wont run? Anybody know the answer and what other limitations im going to experience going from version 5.0 down to 4.0.20-standard.

Last Id MySQL 4.1.21-standard-log
we have a very busy database server, and alot of insert is going on in it. but my program requires to get the last_inset_id. i did this using PHP mysql_insert_id(). now the problem is since there are alot of insert, i believe that mysql_insert_id() is getting the wrong id thus i am having duplicate id's in my other table. so linking my two tables through id is screwed up. id is auto_increment btw.

can i specify the last_insert_id to only look at a specific database.table?

Any Way To Dump From Mysql 5.0 To 4.1.22-standard?
I have a MySQL 5.0 database that I have dumped to a flat file with:

mysqldump -u username -p databasename > mydatabase.sql

I have written a cgi perl script to import the dumpfile into a new table in an existing database. The script runs fine when I run it on the local host. But when I upload the same script and dumpfile onto a webserver that is running MySQL 4.1.22-standard, I get the following error when trying to import:

DBD::mysql::st execute failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ';
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101' at line 7 at mysqlimport.cgi line 24, <FH> chunk 1.

I would have thought that a dumpfile would not be version dependent, but apparently it is. The database is very simple.

- Is there any way to edit it so that it will import into the lower rev db?
- Or is there a way to dump it into a lower rev format?
- Or is there some other solution (other than upgrading the server)?

Table Authors:

Subqueries And DISTINCT From MySQL 5 To 4
Ugh... been working on a project for some time now and I'm just plain stuck and the SQL is getting over my head. I would LOVE any help you can give me. The following query works beautifully fast on my in house machine (mySQL 5) but when I brought it over to the live server (mySQL 4.1) the query takes about 30 seconds to compile... I realize I am not a SQL rock god...

SELECT DISTINCT p.pailid AS PID, p . * , (

SELECT COUNT( * ) AS c
FROM feed
WHERE pailid = PID
AND display =1
) AS numFeeds, (

SELECT COUNT( * ) AS c
FROM comments
WHERE pailid = PID
) AS numComments, c.title AS cattitle, (

SELECT COUNT( * ) AS q
FROM flags
WHERE pailid = PID
AND userid =1
) AS isFlagged
FROM pail p, feed f, category c
WHERE p.pailid = f.pailid
AND f.display =1
AND p.categoryid = c.categoryid
ORDER BY p.date DESC
LIMIT 0 , 50
Should I convert this to JOINS? If so, could someone give me a hand as I am LOST when it comes to JOINS.

Learn Sql Standard
I'm just learning mysql--having no db experience. I'm wondering if my-sql-specific commands overlap with sql standard commands. I noticed when reading the mysql manual, that one of the user comments on the bottom of the page says that the "describe table" and "show tables" are
mysql-specific. I also noticed that they use the non-standard "load
data" command, where "insert" is the standard. I was under the
impression that mysql-specific stuff was just an extension of the
sql-standard, not an alternative. Are there a lot of overlaps like this?
If so, do you recommend any other sites besides the mysql where I could
learn the standard commands first?

Subqueries On 4.0.25 Without Subqueries
i have 2 tables. knowing subqueries cant be performed on this version how would i write the following statement?

i have 2 tables
table.a, table.b

I want to select all records from table.a that match table.a.id = table.b.id WHERE table.b.varchar = 'value'

once the table.b.varchar is found, get table.b.id and match it to any records in table.a.id that match it.

Can this be done in 1 statement. I'd hate to have to run a loop here. I've tried without success JOIN statements.

here is one of my attempts:
"SELECT table.a.* FROM table.a, table.b WHERE table.a.id = table.b.id AND table.b.varchar = '$value' GROUP BY table.a.sortkey ORDER BY table.a.is_primary DESC ";

this does return 1 row, and joins the 2 tables accordingly, however i need all rows in table.a that match the table.b.id where table.b.varchar = 'value'

Theory Of Subqueries For 4.1.7
While converting SQL statements for a database change, I discovered a
big performance hit in MYSQL with subqueries vices Sybase. I'm hoping
that someone might be able to help me understand why?

I have two tables USERS (2200 records) and JOB Decriptions (163
records). I wanted to retrieve all the job description not in the
USER table. (No Indexes on JOBDESC currently)

select JOBDESC from JOBS where JOBDESC not in ( select JOBDESC from
USERS where JOBDESC not NULL )

In Sybase the query returns in about .56 secs
In Mysql 4.1.7 query returns in about 8.78 secs

The funny thing is if I run the query like so

select JOBDESC from JOBS where JOBDESC not in ('President','Vice
President','Treasaur','Secretary')
returns in .03 secs.

Those four descriptions are returned by the inner select.

All select statements individually return in .03 secs.
I created indexes on both tables for JOBDESC and reduced the time to
..97 secs. I used explain command to help understand what is going on
hence the indexes, but why the difference in speed?

Subqueries And The IN Operator
hey all,

i am having serious problems with getting my head around why this will not work. i am trying to return a number of games played with a count of the number of people in it. the table structures are as follows:

games

gameref | gamepot | gamedate | gamelength |

..1...... | .... 50.... | 12.12.04 | ... 03.00.00 |

winnings

gref | pref | amountwon | stake |
1 . .| 1 .. | ....20 ...... | 10...|

i have used the dots to try and keep the table in some sort of form. i have only entered one row of data for each just to show the format of it, if this is not enough please ask for more.

the games table holds each game that has been played, the total pot available to be won the date played and the duration of the game.

the winnings table is teh winnings of each player in each game. the gref is the game it refers to, the pref is teh player it refers to, (there is a player table but is not used in this query at all). the amount that player won and the stake they entered into the pot.

if ya didnt gues its a poker database. my problem is as follows.

Quote: $sql = ("SELECT games.*, COUNT(winnings.gref) as playercount, winnings.gref
FROM games, winnings
WHERE gameref = gref
group by gameref
order by gamedate");

this query works a treat. it counts the amount of players in each game and outputs it all nicely.. but i wanted to edit the query to be able to show just all the games a single player had been in.

Quote: $sql = ("select games.*, COUNT(winnings.gref) as playercount, winnings.gref
from games, winnings
where gameref in (select gref from winnings where pref ='$pid')
group by gameref
order by gamedate");

$pid is passed into the page by

Quote: pt_register('POST','pid');

but this throws an error

Quote: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/ghoxmfjz/public_html/database/poker/allgames.php on line 32
Query failed!

line 32 is:

Quote: $nrows = mysql_num_rows($result);

i can get it to work if i substitute the subquery for (1,2,3) being the first 3 games played. this would assume a certain player would have been in these 3 games.

the problem i get is that the COUNT function just counts every player in everygame not the individuals. if i group it by gref it counts them (sort of.. it doubles the count) but then does not return any of the other information for the query.

i am very confused any and all suggestions of things to look at or consider or a straight ur doing XXX wrong would be grand.. thx all

oh btw if you wish to look at the output if that helps the URL is:

Problem With Subqueries
I am trying to find the rows in table1 that do not have matching rows in table2 in order to set the value of a field in table1. I can get a query to return the rows that do have matches with this query:

select item1 from table1 where item1 in (select item2 from table2);

However, the following queries return no data:

select item1 from table1 where not(item1 in (select item2 from table2));
select item1 from table 1 where item1 <> all(select item2 from table2);

My understanding of the first query is that the not operation would be applied after evaluating whether item was in the result of the subquery. With the second query, I thought it should return true if item is not equal to every result in the subquery. If I try to use a left join and then simply find the rows that have a null value coming from table2, I get the correct resultset but I can't use that as a subquery for my update statement. Since table1 is what is being updated MySQL tells me that table1 cannot be used in the subquery for the update statement. I have this working in a stored procedure by importing the result of the join into a temporary table, but I'd rather not have to write all that data and then delete it.
