Query Analyzer shows negative numbers as positive numbers

by: pj | last post by:

Why does M$ Query Analyzer display all numbers as positive, no matter whether they are truly positive or negative ? I am having to cast each column to varchar to find out if there are any negative numbers being hidden from me :( I tried checking Tools/Options/Connections/Use Regional Settings both on and off, stopping and restarting M$ Query Analyer in betwixt, but no improvement.

SQL - Total results

by: Darryl Kerkeslager | last post by:

I'm trying to construct a simple query (Hah! then why can't I figure it out if it's so simple?) that totals the results where the drug test results are True, negative being treated like any other result. However, instead of giving only the count of the True results for each result, I'm getting the count of the tests, regardless of result: a person taking three drug tests, all negative, will display: offender_id off_name ...

TIMEDIFF()

by: chrisdebritain | last post by:

Hello, I am trying to construct a query to be run against a timestamp so that data is displayed from a certain time backwards. For example: SELECT Time_Stamp, Park_Name, Mill_Name, Size, Email_Type FROM emails WHERE TIMEDIFF(NOW(),Time_Stamp) <= '96:00:00' ORDER BY Time_Stamp LIMIT 0, 30 This would theoretically pull all the records from this moment until 4

Finding the results of a query

by: Jerim79 | last post by:

I am working on a script that will query a database for a FNAME/LNAME combo. If it finds the combo, I need it to do one set of instructions. If it doesn't find it, I need it to do something else. What I can't figure out is what variable to check against. Here is what I have for the relevant part of the script: $connection = mysql_connect($hostname, $username, $password); mysql_select_db($databasename) or die ("Cannot connect to database"...

I have a TIMEDIFF statement that works in MYSQL, but not in C

by: bsm2th | last post by:

In mysql, this statement gives a negative answer, meaning the start is a later time than the end. This won't work in C, because the hour variable is unsigned. Does anyone know of another way to tell whether or not a time comes before another time.. Thanks Bob The statement I used was SELECT TIMEDIFF('01:00:00','02:00:00');

A character with a negative value

by: Martin Wells | last post by:

Plain char may be signed or unsigned. Typical ranges could be: CHAR_MIN == -128, CHAR_MAX == 127 CHAR_MIN == 0, CHAR_MAX == 255 The Standard says that the behaviour is undefined if we pass an argument to the "to*" functions whose value is outside the range of 0 through UCHAR_MAX. This most certainly should have been CHAR_MIN through CHAR_MAX.

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
