Delete Query
Here’s what I’m trying to do:
- Output the last 60 results in my db - works
- Delete a record – does not work
Can anyone see why my delete query won’t work?
It seems to have two problems:
1) It does not delete a record
2) The header re-direct says can’t modify header information Code:

Delete Query Not Working As Expected
I have 2 different php forms. One makes sure that a user has chosen an unique user name (below): $query_rsApp = "SELECT * FROM users where UserName=".$Registered." "; This Select query works right every time (as far as I can tell). I have a form that I want to use to delete user records. This Delete query works fine if the username and password are both numeric... But if the username or password is text, it returns the error "UNKNOWN FIELD 'whatever'" where whatever is my search criteria that I am trying to use.

Delete Query Takes HOURS
why on EARTH would this query: Code: DELETE FROM `test_zip_assoc` WHERE id > 100000 take an entire day when there are 10 million records in this database: Code: +--------------+------------------+------+-----+---------------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+------------------+------+-----+---------------+----------------+ | id | int(12) unsigned | | PRI | NULL | auto_increment | | f_id | int(12) unsigned | | | 0 | | | zip | varchar(5) | | | | | | lat_radians | decimal(12,11) | | MUL | 0.00000000000 | | | long_radians | decimal(12,11) | | MUL | 0.00000000000 | | +--------------+------------------+------+-----+---------------+----------------+

Query - Create The Mysql Query To Get All Fields
I've a table "article". Any article is of a type in table "type1" or "type2" Each type may be of a model in table "model1" or "model2". Each model can be on a certain make, also in 2 tables, "make1" and "make2". they are a few possibilities. "article" can be of "type1" or "type2" "type1" can be of "model1" only - "type2" can be of "model1" or "model2" "model1" can be of "make1" only - "model2" can be of "make1" or "make2" "article" has "type.id" field (char10). If it start with "my" then it's a "type2", otherwise is a "type1" "type1" has only "model1.id" field. "type2" has "model1" and "model2" fields. If one is filled, the other isn't "model1" has only "make1.id" field. "model2" has "make1.id" and "make2.id" fields. If one is filled, the other isn't so here are the possibilities: article -> type1 -> model1 -> make1 article -> type2 -> model1 -> make1 article -> type2 -> model2 -> make1 article -> type2 -> model2 -> make2 Now, I must create the mysql query to get all fields given the "article.id". Is it possible ? How ? will this work ? in pseudo-code article left join type1 articleid = type1id inner join model1 type1id = model1id //inner because if type1, the model is 1 inner join make1 model1id = make1id //inner because if model1, the make is 1 left join type2 articleid = type2id left join model1 type2id = model1id left join model2 type2id = model2id left join make1 model2id = make1id left join make2 model2id = make2id

Delete A Row
This should be simple enough but for some reason it's not working. The $name is a number which is being posted across when the user clicks submit. I want the PHP to then access the Database with this number and use it to delete the staff ID (which is a PK). With this code I get the error: Warning: ociparse(): supplied argument is not a valid OCI8-Connection resource in /homedir/ilex-s01/jmsuther/public_html/DeleteStaff.php on line 16 Warning: ociexecute(): supplied argument is not a valid OCI8-Statement resource in /homedir/ilex-s01/jmsuther/public_html/DeleteStaff.php on line 17 ; The code is: $name = $_POST["staffnodelete"]; IF ($staffnodelete=="" ) {print "You selected $name - for deletion ";} putenv("TNS_ADMIN=/u1/oracle/Products/shu10g/network/admin"); $con = OCILogon("username","password","10g"); $query = "DELETE FROM staff WHERE staffno = $name"; $query = $query_post [$name]; $stmt = ociparse($conn, $query); ociexecute ($stmt);

Not Able To Delete
I've written a script to display all records in a database table and allow the user to select a record for deletion by entering it's ID number into a form at the bottom of the page. When they click on the Submit button, it refreshes the page & shows the entire record that they selected and it asks if they're sure that they want to delete it. There's 2 radio buttons that that allow them to select either "Yes" or "No". Everything is working fine up to that point. Where I run into problems is that no matter whether they choose yes or no, the record does not get deleted.

There is a corresponding session with each 'path' row. Based on the session, I want to retrieve the path name and delete its counterpart folder name (and all it's sub-files it may contain).

MySQL Query - 2 Steps In 1 Query?
I have two tables and the first one contains 2 main fields- 'user_id' and 'username'. The second table contains 2 main fields- 'poster_id' and 'message'. And what I need to do is lookup the user_id from the first table with the username, then pull * from the message_table if the poster_id matches the value pulled from the first table. Now, I got this working without a problem at all but I had to use 2 queries to do it (1- pull the user_id from the first table by matching it with the username, then 2- using the first id, pull everything from the second table that matches it). Is there an easy way to do those 2 steps in 1 query? I know there must be some way since this seems like a fairly simple and routine problem, but I can't find it online or in any books I have here.

Delete From Database
I have code that does not delete from a database. The same code (cut an paste in the same file, but different function and having a different query) works. So, of course, I tested the query interactively. I echoed the query and did a cut and paste when interactively connect to the database. That one worked so it isn't the query since interactively it is seeing exactly the same thing as the code produces. Here is the code: function deleteCatalog($catalog) { $query = "DELETE FROM CatalogNames WHERE sCatalogID='" . $catalog . "'"; mssql_select_db($database_Login, $_SESSION['Login']); $result = mssql_query($query, $Login); ... } The $query echos: DELETE FROM CatalogNames WHERE sCatalogID='CMP' As an example of code that works (in the same file) function addToCatalog($cat_id, $cat_name) { $query = "INSERT INTO CatalogNames (sCatalogID, sCatalogName) " . "VALUES ('" . $cat_id . "', '" . $cat_name . "')"; mssql_select_db($database_Login, $_SESSION['Login']); $result = mssql_query($query, $_SESSION['Login']); ... } The second and third lines are identical (cut and pasted) as in other places in the same code. In fact, it is only in this file that I do all the database work. Every other function works. This is the only delete, however.
