Mysql
Home >Mysql > Setting query results output
In Oracle to format results within sqlplus prompt there are formatting output commands like: col COLUMN_NAME format a20... By default, Mysql prints column names. When you need to print results without the column name, let'say we do not want print the name of the column (user) as in this example ... mysql> select user from user; +------------------+ | user | +------------------+ | cust03 | | cust02 | | cust01 | | root | +------------------+ 3 row in set (0.00 sec) So set column-names=FALSE:
$ mysqlserver01> mysql -p --column-names=FALSE
Enter password: mysql> use mysql; Database changed mysql> select user from user; +------------------+ | cust03 | | cust02 | | cust01 | | root | +------------------+ 3 row in set (0.00 sec) Warning: include(ads/text468x15.html): failed to open stream: No such file or directory in D:\inetpub\webs\fishscriptcom\documents\view_document.php on line 131 Warning: include(): Failed opening 'ads/text468x15.html' for inclusion (include_path='.;C:\php\pear') in D:\inetpub\webs\fishscriptcom\documents\view_document.php on line 131 Tutorial Creazione di un database e assegnazione di grant e password Primi passi [Mysql] mysql dictionary tables how list and find tables and other objects of databases schemas [Mysql] mysql inserting data with LOAD DATA INFILE common errors and solutions [Mysql] Query per generare sql dinamici tecniche dba [Mysql] Shell scripts executing mysql instruction basic samples to execute sql and other commands via script and put results on file [Mysql] mysql load file into a table Example with LOAD_FILE function to insert a file in longblob column [Mysql] Script Running existing sql files through prompt (like dos) Executing sql script [Mysql] Utenti e grant Assegnazioni di grant su tutto il database a nuovi utenti [Mysql] Comandi Data di oggi Stampa data corrente [Mysql] Show databases visualizza i databases Comandi iniziali [Mysql] Shutdown Chiudere Mysql [Mysql] Uscire dalla shell di mysql Comandi di base [Mysql] Funzione CONCAT Concatenare i valori delle colonne di una query [Mysql] CURRENT_DATE() Data odierna [Mysql] Drop index Cancellare un indice [Mysql] Estrazione di occorrenze casuali da una query Ordinamento attraverso la funzione RAND() [Mysql] Esempio formattazione data (giorno,mese,anno) Formattare una data all'interno di un'istruzione SELECT con la funzione DATE_FORMAT [Mysql] Creazione di un database e di una semplice tabella Primi passi con Mysql [Mysql] Inserire dei dati Istruzioni di base [Mysql] Login prompt mysql Accedere a mysql dalla shell [Mysql] Visualizzare gli indici associati ad una tabella show index [Mysql] Creazione indice Sintassi e finalitą [Mysql] QUERY: Clausola WHERE e LEFT JOIN [Mysql]
