I have this table join below and I am getting an invalid query. How can I put the 15th line ($sql .= " group.id = master.id
"; and the 17th line ($sql .= " where ".$currentrow_sql ; together. Is it even possible to do that?

Table Join Query
I'm trying to join multiple database tables and having a little trouble with it, hope someone can help: There are 3 tables with columns: id, user, date, time, action I'm trying to get user, date, time and action from all 3 tables where the user equals "anyuser" and sort the result by date DESC, time DESC.
How To Join Three Table Into A Little Complicated Query
I am using version 4.1.22. I simplifying this for example's sake. I have three tables: order: order_id tip_amount item: item_id order_id price vendor_id vendor: vendor_id vendor Name Each order can have many items. Each item has one vendor. I need a query that displays all orders grouped by order_id, EXCEPT where there are multiple vendors where I need it to show grouped by order_id in the first column then grouped by vendor_id in the second column. Plus I need the tip_amount to show ONLY on the first line of the order. It would like this (notice order# 299 has two entries and the tip amount was added to the first record vendor record that order): PHP order_id vendor_name total tip298 ABC $30 $2299 DEF $25 $4299 XYZ $12 300 LKW $17 $7...
SELECT Search Query - Table Join Required? Help Please!! (PHP + MySQL)
I have a search form that has: - drop down with states (nsw, vic etc) - drop down with all business categories (retail, commercial etc) - keyword / postcode field (2000, or 'builders') The user gets results returned from the business table filtered by state (mandatory), which category is selected (mandatory) and by keyword (optional) or postcode (optional). If keyword / search phrase is given then it will do search of the keywords fields of the business table (has already been indexed) in the selected category only. If postcode it will return all businesses in that category in order of distance from the given postcode. I have 5 tables (additional fields ommitted): 'state' state_id, name 'businesses' business_id, keywords, name, postcode, state 'postcodes' fromPostcode, toPostcode, distanceKMS 'categories' category_id, name 'business2category' business_id, category_id Please dont thing i'm just pawning off my work here!! Basically, i've got this working already, but only just, and in a very long and convulted format. Its far too long to post here, but since i'm not fully versed in table joins, i've been searching individual tables (e.g. SELECT *,MATCH AGAINST etc), building arrays, searching arrays again, and then building results at the end to fit into the paginator. Now the search is taking too long to perform, and i need a leaner alternative. not to mention theres way too many lines of code, and i just know theres a better way. There must be a very simple way to achieve the following searches using table joins, can anybody please help me with 3 search examples below so i can try to understand joins better? Search 1: State + Category only Search 2: State + Category + Keyword Search 2: State + Category + Postcode If there is no postcode, the others still need to display the data filtered by distance from a default postcode of 2000. I'd really appreciate if anybody has a few minutes free to help out here, and hopefully teach me something about effective table joins and searching. I've omitted the extra fields and tables from the real structure, and just left the relevant ones above - if theres anyhing missing or not making sense please let me know and i'll fix up asap.

Directory Name Invalid
For testing purposes I have PHP installed and I have MySQL installed on my local laptop. Windows XP Pro I am just learning both of them. I have read quite a few chapters in the MySQL Manual. Enough to allow me to get around in MySQL and directly create tables an view information in them, upload .txt files into the tables, etc etc. I am receiving an error when I try to connect to MySQL via a PHP script. I have no problem connecting to MySQL via Command Line. The error I receive is "The directory name is invalid." Here is my code... I am not sure where to put the directory name or where to put the directory path in order to make it valid. I am not sure what directory it is talking about. <html> <head><title>Connect to MySQL</title></head> <body> <?php //connecting to the mysql server uses a mysql_connect command. $link = mysql_connect("locoalhost",$_POST['username'],$_POST['password']) or die("Connect Error: ", . mysql_error()); echo 'Successfully Connected.

Invalid Argument While Using BCP (Script)
This will be a 50/50 question. It's either something that the SQL experts can answer or a scripting forum. I'm new to SQL and just coming to grips with getting familiar with scripts. I've developed a small script for my workplace that will connect to a remote server and extract the specified table that I want, zip it up and then copy it back to my local machine. This works fine until it tries to run the bcp command. If I tivoli to the remote machine and type the bcp command in command prompt it works fine. However when executed from the script it throws an invalid argument and seems to refer to the "-" minus I place in front of the U (user) or P(pwd). The script echos the users table request to a file which is then copied to the remote server (SQLtable.cmd) and then PSEXEC is called to connect to the server and run the script. e.g. psexec \%Server% -u %user% -p %password% "C: empSQLtable.cmd" PSEXEC then returns the following error. C:WINNTSYSTEM32>Bcp FrontOff..SHIFT_TER_DATA out C: empdmpnlSHIFT_TER_DATA.dat ûUsa ûPpwd (chopped off the -n) Unknown argument '¹Usa' on command line. Sorry about all the data, just hope someone can help. Must be an easy way. The small script which psexec is executing contains two simple lines. Bcp FrontOff..SHIFT_TER_DATA out C: empdmpnlSHIFT_TER_DATA.dat -Usa -Ppwd -n wwzip -9 C: emp\%username%SQLtables.zip C: emp\%username%*.*
Invalid Characters With PHP And MySQL
I am writing about a situation that our client is currently experiencing with Linux Mandrake, Apache, MySQL and PHP. We successfully deployed a website running on this type of system for a period close to two years. It has a HTML GUI component that the client can type or paste content into and it serves-up dynamic pages in PHP from a MySQL database. Recently the web site was hacked by the Travel Bug virus and it forced the client to restore the web site and server software mentioned below. Original Install Mandrake 8, MySQL 3.23.32, PHP 4.0.06 and Apache 1.3.26-x.x Current Install Mandrake 9.0, MySQL 3.23.52-1, PHP 4.2.3-1.1 and Apache 1.3.26-6.1 The current install has lead to new problems. Content with double and single quotes are showing up as squares or question marks. For example, I have a page that is showing the square symbol in place of double quotes. If I do a view source on that specific page I can see the double quotes but if I telnet into the server and query the MySQL record belonging to that page the square or double quote character is nowhere to found. The following items are the steps we tried to understand why this is happening. First, we did the following to test the integrity of the MySQL backup file. We Restored the MySQL database on our test environment which has the original software specs mentioned above but on a window server running IIS not apache. I did a restore of the MySQL database file and did not get any invalid characters. Even though the environment isn’t completely identical to the clients we can make the assumption that the dump file wasn’t corrupted. Second, possibly content editors were copying and pasting from word into the HTML GUI component thus creating these invalid characters. In most cases yes but I personally noticed the invalid character issue with a page that doesn’t use the HTML GUI component. Third, Possibly the configuration especially the character set from the original version to the current version of MySQL is not configured correctly. We believe this to be the primary issue. The resolution is to configure or reinstall MySQL and restore from backup. Fourth, has anyone tried the PHP functions to convert the invalid characters. A request was to look into the iconv() function. The iconv library functions convert strings between various character sets encodings. This involves compiling the PHP interpreter which is why I haven’t tested it. Fifth, Can some other process running on the server be causing this? Altogether, we soon will begin creating a test server identical to the original settings and step through the install and try to recreate the invalid character issue. But, if anyone has experienced this invalid character issue or has more information that would benefit us your help would greatly be appreciated.
Invalid Use Of Group Function - Max(`mainid`)+1

Valid/Invalid Column Names
I'd like to present tabular data in HTML with the first row being the names of the columns in my database. However, I'd like them to be more presentable; for example 'I.P. Address' instead of 'ip_address'. I was wondering if a name like 'I.P. Address' could ever somehow be a valid column name or not.
Invalid MySQL-Link Resource
I'm getting the error message 'Supplied argument is not a valid MySQL-Link resource' (applies to the 3rd line of code) when the code below executes: $delete_part_no_query = "DELETE FROM prices WHERE part_no == '$part_no_to_delete'"; $delete_part_no_result = mysql_query($delete_part_no_query); $num_delete_part_no_result = mysql_affected_rows($delete_part_no_result); The query works fine and I'm under the impression that 'mysql_affected_rows' should be used to return the number of rows affected by DELETE. However, I keep getting the above error message.

This query actually is used to create a listbox. The index has 62 separate values. This query would usually return: Code:

Using Both JOIN And AVG In One Query
I'm looking to use both JOIN and AVG in the same query but not sure how I'm going to it. I'm VERY new to using MySQL. The ultimate goal is to take one table which counts votes for various criteria in a poll. I want to average those results together. Then I want to join that averaged table with another table and GROUP By URL (which is the column common to both tables). I've successfully used AVG with the first table and used JOIN (with a totally different) table, I'm not sure how to approach using both together.
Help With A Query Join?

Need Query To Join 2 Tables Through A 3rd
I have a table called client (primary key = clientID), another called clientFamily (pk = clientFamilyID) and a table that joins those two called client2clientFamily. The latter table only has two rows: clientID and clientFamilyID (no pk). On the client table, say the client has 3 children and 2 siblings. Those would go on the clientFamily table. The part I don't know how to do is how to assign those 3 kids and 2 sibs to that particular client. I know I do it via the client2clientFamily table but I don't know the query. I'm also not sure I'm thinking of this right. The fields on clientFamily start off like: clientFamilyID spouseFirstName spouseMiddleName spouseLastName spouseOccupation motherFirstName motherLastName motherOccupation fatherFirstName fatherLastName fatherOccupation I think that part's ok, but if I add: childFirstName childLastName childBirthday childSex and sibFirstName sibLastName sibOccupation how are, for example, a child's birthday and sex are going to be linked to the correct child? And a sib's occupation linked to the correct sib? Now I'm wondering if I need a separate table for clientChildren (and a joining table client2clientChildren) and another one for clientSibs (& client2clientSibs) instead of putting everything in clientFamily. Ugh.
Join Query Problem... Help!
I have two tables: STORES ------- id name ORDERS ------- id total cost store_id date_ordered I want to select ALL stores and their total sales for a date range. Here's my query: SELECT stores.id, stores.name, SUM(orders.total), SUM(orders.cost), COUNT(orders.id) FROM stores LEFT JOIN orders ON stores.id = orders.store_id WHERE orders.date_ordered > 'xxxx-xx-xx xx:xx:xx' GROUP BY stores.id This works, except that it only selects stores that have orders. If I leave out the WHERE clause, it then selects ALL stores, even without orders, and populates the sums with "null" That is what I want - if the stores don't have any orders, the results should simply return null or 0. However it seems that stores without orders are simply not being returned in the results at all.

Multiple Join Query
I have a database with quite a lot of tables all with foreign keys of each other. One of the tables has a one to many relationship (it being the one) with two tables, but it only uses one of them for any one record. Which one is used depends on a field in the main table. This essentially defines three different types of the same item, which has mostly the same fields, but two of them also require additional, multiple record (hence the one to many) information. So the table has a field 'type' which takes the value 1 (in which case no other table is referenced), 2, (in which case the first other table is used) and 3 (in which the other table is used). What I would ideally like to do is have one SQL query which returns information (from the main table) about any record which applies to the day (as it is part of a calendar system) specified in the query. The problem is that to decide if the record is relivent, the query must look through at most two of the three tables. I doubt that there is a way to specify in an SQL query to join to a table depending on the field of the first, and to join all three and perform the query could produce unexpected results if there were for any reason records in the third which referred to the first table. I could do this with several queries, but it would probably be more efficient to do it by one query. Would I be able to do an outer join on this?
Ranking Query (self Join)
I would like to get a rank (row # of ordered results) of an article based on its average rating in relation to all other articles. I have a ratings table that holds all of the individual votes cast by users (ratingID, articleID, userID, rating). So I need to order the articles by AVG(ratings.rating) and then come up with an individual article's row # to find its ranking. I know this involves joining the ratings table on itself with a greater than or less than operator, but i'm completely lost when it comes to self-joins. I know this is easy, but there is a small trick to it and i'm clueless.

As I understand subqueries do not work in version 4.0 Here is what i am trying to do; select a, b from table1 where table1.b != (select distinct c from table2); Other words: table1.b and table2.c have values I want to match on I run select a, b from table1; subtract all out using select distinct c from table2; and leave me with a and b from table 1 that have no corresponding value of c in table 2
Generating A JOIN Query
I need some help with a MySQL query, probably a JOIN. Here is the situation: I have two tables. The first one contains customer info. Table CUSTOMERS id | name | address id ... customer ID (MEDIUMINT, autoincrement) name ... customer name, for example John Doe address ... customer shipping address Then I have the second table which contains sale info from all customers....
Query Involving JOIN
I have two tables populated during the use of an application to log user events and application states. They are named "EventTable" and "StateTable" and the structures follow: EventTable: ID EventTimeStep EventID -- ------------- --------- 1 5 E1 2 22 E2 3 56 E3 StateTable ID StateTimeStep StateID -- ------------- ------- 1 1 S1 2 39 S2 I want to perform a query that reports the StateID of the application at the time that each event was logged to the EventTable. The desired output is: ID TimeStep EventID StateID -- -------- ------- ------- 1 5 E1 S1 2 22 E2 S1 3 56 E3 S2 I have tried to create a query with an INNER JOIN where the value for the StateID output field comes from the last row in the StateTable WHERE StateTable.TimeStep <= EventTable.TimeStep and where I use a GROUP_BY EventTable.ID to merge the following rows from the join: 3 56 E3 S1 3 56 E3 S2 However, the closest I can get is a query that gives me the wrong state when applying the GROUP BY clause 3 56 E3 S1 I also think that the queries I have written is slow and inefficient. Is there a better way to perform this query or is my database design fatally flawed?
