  • stuck with creating rent table

    - by From.ME.to.YOU
    i want to create a php with mysql to do the following: lets say that i have a shop i want to rent, rent will be weekly or monthly. I'm searching for the best way to create this table, so i can do easy queries to calculate free weeks or months. EDIT let say i have ID, START_DATE,RENING_TYPE,CLIENT_ID where Start_date is the start date for renting, and RENTING_TYPE is weekly or monthly how should i run a query to know all the empty weeks or month so new clients may reserve that week/month for example a client reserve July month another client reserve the first week in June, if a new client logged in to my system and want to check all the available weeks/months, how can i achieve that ?

  • SQL query for selecting most recent entries

    - by Mr_Skid_Marks
    A table in my database has a column, DATE_ADDED (stored in seconds). I want to extract all rows with the most recent date (aka largest value for DATE_ADDED). The only solution I have come up with is to SELECT all the rows in ASC (ascending) order, grab the last entry from the table, check the date on this, and perform another SELECT on the table but this time only for the discovered DATE_ADDED. Is it possibly to simplify this series of queries into a single one? My thought is I should be able to do a SELECT on all of the largest values in the table, but I am struggling to come up with a proper query.

  • Using closes sql connection brought over by a function

    - by iefpw
    Would this using close this _connection? using(SqlConnection _connection = Class1.GetSqlConnection()) { //code inside the connection } //connection should be closed/ended? I'm just wondering because GetSqlConnection() is a static function of Class1 and the whole connection might not be closed because it is calling outside class' static function instead of straight? using(SqlConnection _connection = new SqlConnection(_connectionString) { //code inside the connection }

  • Why isn't INT more efficient than UNIQUEIDENTIFIER (according to the execution plan)?

    - by ck
    I have a parent table and child table where the columns that join them together are the UNIQUEIDENTIFIER type. The child table has a clustered index on the column that joins it to the parent table (its PK, which is also clustered). I have created a copy of both of these tables but changed the relationship columns to be INTs instead, have rebuilt the indexes so that they are essentially the same structure and can be queried in the same way. When I query for a known 20 records from the parent table, pulling in all the related records from the child tables, I get identical query costs across both, i.e. 50/50 cost for the batches. If this is true, then my giant project to change all of the tables like this appears to be pointless, other than speeding up inserts. Can anyone provide any light on the situation? EDIT: The question is not about which is more efficient, but why is the query execution plan showing both queries as having the same cost?

    DoCmd.TransferText acImportDelim, Import-Accounts, "tableImport", _ "C:\Documents and Settings\accounts.txt", True The second parameter: Import-Accounts is the actual name of the saved import specifications. supposedly it does NOT need to be in quotes; however in this case since there is a - there it is treating it as if i were doing an operation. is there a way i can force it to treat it literally instead of as an operation?

  • how to join on varchar(32) and binary(16) columns in sybase?

    - by Paul Sanwald
    I want to join two tables on a UUID. table A's UUID is represented as varchar(32). table B's UUID is represented as binary(16). what's the best way to join a varchar to a binary column? I've tried using some sybase functions for this, but I'm getting different results and unsure of why: select hextobigint('0x000036ca4c4c11d88b8dcd1344cdb512') 3948051912944290701 select convert(bigint,0x000036ca4c4c11d88b8dcd1344cdb512) -2877434794219274240 what am I missing about convert and hextobigint? I must be misundstanding at least one of these functions. thanks for your help!

  • MySQL: averaging with nulls...

    - by Zombies
    Is there a simple way I can exclude nulls from affecting the avg? They appear to count as 0, which is not what I want. I simply don't want to take their average into account, yet here is the catch, I can't drop them from the result set, as that record has data on it that I do need.

  • Delete rows out of table that is innerjoined and unioned with 2 others

    - by jonathan
    We have 3 tables (table1, table2, table3), and I need to delete all the rows from table1 that have the same ID in table2 OR table3. To see a list of all of these rows I have this code: ( select table2.ID, table2.name_first, table2.name_last, table2.Collected from table2 inner join table1 on table1.ID = table2.ID where table2.Collected = 'Y' ) union ( select table3.ID, table3.name_first, table3.name_last, table3.Collected from table3 inner join table1 on table1.ID = table3.ID where table3.Collected = 'Y' ) I get back about 200 rows. How do I delete them from table1? I don't have a way to test if my query will work, so I'm nervous about modifying something I found online and potentially deleting data (we do have backups, but I'd rather not test out their integrity). TIA!

  • insert into select from other table

    - by user3815079
    I need to add multiple records based on data from another table where the event is the same. I've found on this forum insert into table2(id,name) select "001",first_name from table1 where table1.id="001" as possible solution for my question. So I thought this should be the following syntax: insert into reservations(event,seat) select "99",id from seats where seats.id>0 to add all seats to event 99. However when I run this query mysql gives the message 'MySQL returned an empty resultset (0 rows). (query 0.0028 sec)' and no records were added. I translated the message so could be sligthly different. When I only use the "select "99",id from seats where seats.id0" query, it returns me 1080 rows.

  • IF statement within WHILE not working

    - by Ds.109
    I am working on a basic messaging system. This is to get all the messages and to make the row of the table that has an unread message Green. In the table, there is a column called 'msgread'. this is set to '0' by default. Therefore it should make any row with the msgread = 0 - green. this is only working for the first row of the table with the code i have - i verified that it is always getting a 0 value, however it only works the first time through in the while statement .. require('./connect.php'); $getmessages = "SELECT * FROM messages WHERE toperson = '" . $userid . "'"; echo $getmessages; $messages = mysql_query($getmessages); if(mysql_num_rows($messages) != 0) { $table = "<table><tr><th>From</th><th>Subject</th><th>Message</th></tr>"; while($results = mysql_fetch_array($messages)) { if(strlen($results[message]) < 30){ $message = $results[message]; } else { $message = substr($results[message], 0 ,30) . "..."; } if($results[msgread] == 0){ $table .= "<tr style='background:#9CFFB6'>"; $table .= "<td>" . $results[from] . "</td><td>" . $results[subject] . "</td><td><a href='viewmessage.php?id=" . $results[message_id] ."'>" . $message . "</a></td></tr>"; } else { $table .= "<tr>"; $table .= "<td>" . $results[from] . "</td><td>" . $results[subject] . "</td><td><a href='viewmessage.php?id=" . $results[message_id] ."'>" . $message . "</a></td></tr>"; } } echo $table ."</table>"; } else { echo "No Messages Found"; } There's all the code, including grabbing the info from the database. Thanks.

  • Should user preferences be included in the users table?

    - by Patrick
    I'm creating a members site, and I'm currently working on the user Preference settings. Should I create a table with all the preference fields (about 17 fields) or should I include them in the main member table along with the account settings? Is there a limit as to how many fields I should have in a table? currently the member table has about 21 fields... not sure if its okay to add another 17 more fields when I can easily just put them in another table. It'll take more coding to pull up the data though... any sugguestions?

  • Selecting only the entries that have a distinct combination of values?

    - by Theodore E O'Neal
    I have a table, links1, that has the columns headers CardID and AbilityID, that looks like this: CardID | AbilityID 1001 | 1 1001 | 2 1001 | 3 1002 | 2 1002 | 3 1002 | 4 1003 | 3 1003 | 4 1003 | 5 What I want is to be able to return all the CardID that that have two specific AbilityID. For example: If I choose 1 and 2, it returns 1001. If I choose 3 and 4, it returns 1002 and 1003. Is it possible to do this with only one table, or will I need to create an identical table and do an INNER JOIN on those?
