php - MySQL query results are not a resource -


I have trouble with the query in this code. The problem is that I have previously, $ num = Mysql_num_rows ($ result); The part tells me a MySQL error that it expects a resource. Normally when I am getting this error, I have lost a single quote, but I see that I am not getting any problem, although this question is a bit more complex which I have to deal with usually. 

  // Connect to database and $ last_year = idate ("Y") - 1; $ Month = date ("m"); $ Day = date ("D"); $ Query = "SELECT bills.b_id, bills.c_id, Bill.Gr_tatic, bill.voice, bilceddated, customer.b_name, customer.l_name, customer.f_name, customer.phone bills, customers WHERE bill c_id = customer. C_id and bill.is = '0' and added between date ''. $ Last_year. "-". $ Month "-". $ Day. "'And kurt ()"; $ result = mysql_query ($ query); Mysql_close ($ link); $ Num = mysql_num_rows ($ result);

Edit:

Although I already know mysql_close () function problem I can not move forward And removed it and my code still does not work. It works in about a dozen other pages similar to EXACT (in addition to the query). The problem is in the query MySQL error (as previously mentioned) is mysql_num_rows () value of 1 parameter being resource . I am now working on getting specific error.

< P>

Add some error handling to your code.

$ result = mysql_query ($ Query); If (! $ Result) {echo 'query failed:', mysql_error (); Die; }

(You do not want to display the actual query and error message to any arbitrary user in the "real" output code).

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
