mysql - how to update just one column of a table by csv using php -


I have used the following code to update a column of a table, but it will also have the values ​​of the other columns Removes, I could not find the reason to please while ($ data = fgetcsv ($ handle, 1000, ","))! == incorrect) {if ($ data [0] == 'NULL') {$ import = "UPDATE tst_stores SET store_image_url = 'http: //admin.showcasejewellers.com.au/uploads/default_store.jpg'"; } And {$ import = "update tst_stores SET store_image_url = 'http://admin.showcasejewellers.com.au/uploads/". Mysql_real_escape_string ($ data [0]). ".jpg '"; } Mysql_query ($ import) or die (mysql_error ()); } Fclose ($ handle);

Your SQL query is incorrect You must specify that For which example you want to use the WHERE section by using the row 

  update tst_stores SET store_image_url = 'http://admin.showcasejewellers.com. Au / uploads / default_store.jpg 'where tst_stores.id = 10;   
 This will only update the row where the column is equal to ID 10.  
  Note:  I have the column  tst_stores received  in the  id  column and the primary key is you have to change accordingly  
 Just look forward to reading it to see it.

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application.

javascript - Is there any way to add a new parameter to a function programmatically? -

Since I can set the number of expectations by calling a function its function.length Property, do I have to programmatically create the right number of parameters to include in that function at runtime? Example: var xyz = function (a, b) {}; Var BCD = function (A, B, C, D, E, F) {}; // vararg example var doc = document, func_length = xyz.length; Doc.xyz = (function () {returns function (A, B, C, D, E) works for one / but other is not}}}. Call (doctor); / * With `only two parameters ', like' Return function (A, B)`, if this function is used for `xyz` (although in this case 5 works fine), and return function ( If the function is used for 'BCD' (which does not work with only five parameters) with A, B, C, D, E, F) `6 / / Xyz.apply (blank, arguments) Think about ... but which logic ..? : // Returning function (A, B, C, D, E) does not support work with more than five parameters, which will be mostly class - hence my question / I also know very well That I use an obj...
