how to run a file in MySQL
Hello all, This is probably really basic for all of you but I have been trying to find it in the manual without success... My question is if it is possible when you are logged in to MySQL to run a file with sql-statements in, instead of sit and execute each statement seperatly. The file I have is a to clean up my DB and to erase data that I don#t want to have, som all rows in the file is normal DELETE-statetments.

problems...
Hello all, I have I small problem I wonder if there is a easy solution for.. I have a SQL-query where I count out how many users per "n_id" I have. it is a little tricky because I had to do a left joint and compare two tables to get out thoose that are represented only in one of the tables. SELECT SUBS.NE_ID, count(*) from SUBS left join SUB on SUBS.SC_ID=SUB.SC_ID WHERE SUB.SC_ID is NULL group by SUBS.NE_ID; The result I get out looks like this NE_ID count 01 10 02 11 03 4 04 8 And now to my problem, I would like to count this together with another table I have instead of have a seperate query and count them together manually... SELECT count(*) from SUBS_DEAC where NE_ID=01 I want to have these extra query added in my first query and get out the result as above (but now are SUBS and SUBS_DEAC counted together) I can also mention that my MySQL db is version 3.23.55. Unfortunatly is no update to newer version at the moment planed... Would be greatfull to get some help! /Joppe -- ___ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Fwd: how can I do instead of using subselects?
Please help, this must be easy for experinced MySQL users but for me as a newbie isn't it. I have tried to find the answer on the things below in older MySQL manuals but without any success... I have a problem with a few sql-queries because I have written the questions with subselect statements and then will they not work on older MySQL DB:s. Can any one help me to say haw to solve it without subselect! Today looks the questions like this and works fine in MySQL 4.x.x but not in 3.23.55 where I also need to use them: SELECT (SELECT count(SUB.S_ID) FROM SUB LEFT JOIN SUBS ON SUBS.S_ID = SUB.S_ID) /(SELECT COUNT(*) from SUB); SELECT COUNT(SUBS.NEW_ID)+(SELECT COUNT(SUBS_D.NEW_ID) FROM SUBS_D WHERE SUBS.NEW_ID=SUBS_D.NEW_ID) FROM SUBS WHERE SUBS.NEW_ID=1; SELECT (SELECT count(*) from SUBS)-(SELECT count(SUBS.S_ID) FROM SUB LEFT JOIN SUBS ON SUBS.S_ID = SUB.S_ID)+(SELECT count(*) FROM SUBS_D); Another question is how do I do when I want to compare two tables, normally is it no problem to get a list with rows that exist i both tables, but how do I do if I want to to have the diffrence listed instead, the rows that only appears in one of the tables?
