Any suggestions for a real simple C library to query a single MySQL table, nothing fancy here. Just doing a single select * from a table. Any help is appreciated.
SELECT TotalItems.Total_Items
,TotalItems.No_Items_Present
,ItemsTable.No_Of_Items_Ret
FROM TotalItems
INNER JOIN ItemsTable ON
ItemsTable.Item_Name= '" + DropItemName.SelectedValue + "'"
this is my SQL query what I want is to retrieve two column values corresponding to the item I enter in my dropdown list from one table and the no_of_items_ret from another table satisfying the condition of the dropdownlist
I'm getting all the values corresponding to any item I enter what should i do?
This is similar to an earlier problem I was having which you guys solved in less than a day.
I am working with XML files that are generated by a digital video camera. The camera allows the user to save all of the camera's settngs to an SD card so that the settings can be recalled or loaded into another camera. The XSL stylesheet I am writing will allow users to view the camera's settings, as saved to the SD card in a web browser.
While most of the values in the XML file -- as formatted by my stylesheet -- make sense to humans, some do not. What I would like to do is have the stylesheet display text that is based on the value in the XML file but more easily understood by humans.
A typical value that can be written to the XML file is "_23_970" which represents the camera's frame rate. This would be better displayed as 23.970 (or 023.970). The first underscore is a sort of place holder to make a space for values over 099.999. The second underscore, obviously represents the decimal.
My previous (similar) question involved replacing predictable text, and the solution was matching templates. In this case, however, the camera can be set at any one of 119,999 frame rates (I think I did that math correctly).
The approach, I would guess, is to pass a value to the displayed webpage that keeps the numeric values (each digit), replaces the second underscore with a decimal, and replaces the first underscore with either an nbsp or a zero (whichever is easier). If the first character in the string is a "1" (the camera can run at frame rates up to 120.000) then the one should be passed on to the page displayed by the stylesheet.
I have read other posts here regarding wildcards, but couldn't find one that answered this question.
EDIT: Sorry for leaving out important info. I fared better on my first try at asking a question! I guess I got complacent. Anyhow . . .
I should have shown you the code that displays the text in the XSL file as is:
<tr>
<xsl:for-each select="Settings/Groups/Recording">
<tr><td class="title_column">Frame Rate</td><td><xsl:value-of select="RecOutLinkSpeed"/></td></tr>
</xsl:for-each>
</tr>
I should also have given you the URL for the sample file I have been working with: http://josephthomas.info/Alexa/Setup_120511_140322.xml
Is there a way to tell how to get a file size that is uploaded to database?
SELECT [ID]
,[File]
FROM [dbo].[Reports]
I would like to be able to tell user the size of File which is VarBinary(max) field in MS SQL 2005/2008. How to do that?
Maybe the only way to do is to create another column and when inserting file i should also insert it's size in additional column?
hey everyone
i have an access 2007 database where i have 2 tables one is exp_cash and exp_cheque each are link to exp_cat, where exp_cat contains categories list where exp_cash contains id,cat_id,exp_date,exp_amount,exp_note same thing in exp_cheque where when i came to combine them nothing in result unless i remove the cat_name from my query i used a simple query which is
SELECT DISTINCT exp_cat.cat_name, exp_cash.exp_amount, exp_cheque.exp_amount
FROM (exp_cat INNER JOIN exp_cash ON exp_cat.ID = exp_cash.exp_cat_id) INNER JOIN exp_cheque ON exp_cat.ID = exp_cheque.exp_cat_id;
I'm using find_by_sql with Activerecord which I generate another field there that doesn't in the original table as a combination of different fields like:
select (field1 + field2) as new_field_name
If I try to access the newly generated field like:
@user.new_field_name
I get nothing! How do you suggest I should approach this problem
I would like to use Linq instead of below function :
Friend Function IsCollectionInTable2(ByVal apps As DataTable, ByVal collectionId As String) As Boolean
For Each row As DataRow In apps.Rows
If row("CollectionId").ToString = collectionId Then Return True
Next
Return False
End Function
The best I can do is below:
Friend Function IsCollectionInTable(ByVal apps As DataTable, ByVal collectionId As String) As Boolean
Return (From row In apps.AsEnumerable()
Where (row.Field(Of String)("CollectionId") = collectionId)
Select row.Field(Of String)("CollectionId")).Count > 0
End Function
I would like to use Exists or Any in above function. Performance could be an issue,
Do you have any suggestions with my problem. I need to use get and post at the same time.
Get because I need to output what the user has typed. And post because I need to access the mysql database in relation to that input.
It looks something like this:
<form name="x" method="get" action="x.php">
<input name="year" type="text">
<select name="general" id="general">
<font size="3">
<option value="YEAR">Year</option>
</form>
This will output the contents of mysql depending on what the user will check:
<form name="y" method="post" action"y.php">
<input name="fname" type="checkbox">
</form>
And the form action of those two combined will look something like this:
<?php
if($_POST['general'] == 'YEAR'){
?>
<?php echo $_GET["year"]; ?>
<?php
$result2 = mysql_query("SELECT * FROM student
WHERE student.YEAR='$syear'");
?>
<table border='1'>
<tr>
<?php if ( $ShowLastName ) { ?><th>LASTNAME</th><?php } ?>
<?php if ( $ShowFirstName ) { ?><th>FIRSTNAME</th><?php } ?>
</tr>
<?php while ( $row = mysql_fetch_array($result2) ) {
if (!$result2) {
}
?>
<tr>
<td><?php echo $row['IDNO']?> </td>
<td><?php echo $row['YEAR'] ?> </td>
<?php if ( $ShowLastName ) { echo('<td>'.$row['LASTNAME'].'</td>'); } ?></td>
<?php if ( $ShowFirstName ) { echo('<td>'.$row['FIRSTNAME'].'</td>'); } ?>
I really get lots of undefined errors when I do this. What can you recommend that I should do in order to get the value inputted by the user together with the mysql data.
UPDATE static
SET money = money + '100'
WHERE member_id IN (SELECT member_id FROM race WHERE race_id = '$race_id')"
I want to retrieve member_ids and give for all of them +100 money. What's wrong?
UPDATE statistics'
SET money = money + '$money'
WHERE member_id IN ((SELECT member_id FROM races WHERE l_id = '$mem_id'), $other_id)
What's wrong with that? I want to retrieve all member_ids from races and also include to member_id $other_id. Without $other_id it works.
By the way, it gives me "Subquery returns more than 1 row" error.
If I have two tables; Drivers keyed by DriverId and Trips with foreign keys DriverId and CoDriverId, and I want to find all trips where a driver was either the driver or co-driver I could code this in Transact-SQL as
select d.DriverId, t.TripId
from Trips t inner join Drivers d
on t.DriverId = d.DriverId or t.CoDriverId = d.DriverId
How could this be coded as a LINQ query?

Hello guys

I have an SQL statement:
SELECT * FROM customers WHERE BINARY login='xxx' AND password='yyyy'
There are no blob/binary fields in the table, do I need the BINARY after the WHERE what else does it do?
Here is a table structure (e.g. test):
__________________________________________
| Field Name | Data Type |
|________________|_________________________|
| id | BIGINT (20) |
|________________|_________________________|
| title | varchar(25) |
|________________|_________________________|
| description | text |
|________________|_________________________|
A query like:
SELECT * FROM TEST ORDER BY description;
But I would like to order by the field size/length of the field description. The field type will be TEXT or BLOB.
I have a Windows app called via Shell from MS Word that reads and writes to Sqlite. I'm porting it to Mac. On windows I have a batch file:
SQLite3.exe pathtodb\databasename <sqlitecommands.txt
This batch calls the Sqlite command line program, attachs the database, and reads the command from sqlitecommands.txt. The sqlitecommands is dynamically modified(by Word VBA) to read (Select) Write (Update) to/from the database.

When I map/select my database tables with LINQ to SQL I have to option to change the "member" propery, but when i delete the table (because I changed something in the schema for example) and add it again the member value gets "reset". Is it possible to set/override this member programmaticly, so that I dont have to change it by hand everytime
I mean the member option of
'<'Table Name="dbo.table1" Member="table1"
If I want to get a user that has the email address of '[email protected]', how do I pass that as a parameter in linq?

Do I just pass in the variable or?

right click and select the 'delete me'
2.has any other way ???
so how does enable the right-click on google-maps,and then delete the marker.
thanks
