It’s as simple as this: String xmlfile = Data_Array[“XML_File”]; Note that if the dictionary doesn’t have a key that equals “XML_File”, that code will throw an exception. If you want to check first, you can use TryGetValue like this: string xmlfile; if (!Data_Array.TryGetValue(“XML_File”, out xmlfile)) { // the key isn’t in the dictionary. return; // … Read more
DESCRIBE <table>; This is acutally a shortcut for: SHOW COLUMNS FROM <table>; In any case, there are three possible values for the “Key” attribute: PRI UNI MUL The meaning of PRI and UNI are quite clear: PRI => primary key UNI => unique key The third possibility, MUL, (which you asked about) is basically an … Read more
You need to use the LAST_INSERT_ID() function: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_last-insert-id Eg: INSERT INTO table_name (col1, col2,…) VALUES (‘val1’, ‘val2’…); SELECT LAST_INSERT_ID(); This will get you back the PRIMARY KEY value of the last row that you inserted: The ID that was generated is maintained in the server on a per-connection basis. This means that the value returned … Read more
$arr[$newkey] = $arr[$oldkey]; unset($arr[$oldkey]);
The most complete (and correct) way of doing this would be, I believe: if (old_key !== new_key) { Object.defineProperty(o, new_key, Object.getOwnPropertyDescriptor(o, old_key)); delete o[old_key]; } This method ensures that the renamed property behaves identically to the original one. Also, it seems to me that the possibility to wrap this into a function/method and put it … Read more
With array_intersect_key and array_flip: var_dump(array_intersect_key($my_array, array_flip($allowed))); array(1) { [“foo”]=> int(1) }
I suggest you to do: chmod 400 ~/.ssh/id_rsa It works fine for me.
A solution would be to force the key files to be kept permanently, by adding them in your ~/.ssh/config file: IdentityFile ~/.ssh/gitHubKey IdentityFile ~/.ssh/id_rsa_buhlServer If you do not have a ‘config’ file in the ~/.ssh directory, then you should create one. It does not need root rights, so simply: nano ~/.ssh/config …and enter the lines … Read more
Differences KEY or INDEX refers to a normal non-unique index. Non-distinct values for the index are allowed, so the index may contain rows with identical values in all columns of the index. These indexes don’t enforce any restraints on your data so they are used only for access – for quickly reaching certain ranges of … Read more
You can use dict.get() value = d.get(key) which will return None if key is not in d. You can also provide a different default value that will be returned instead of None: value = d.get(key, “empty”)
