Questo articolo elenca l'SQL INSERT sintassi, come implementato da vari sistemi di gestione di database (DBMS). La sintassi è elencata esattamente come l'ha elencata ogni fornitore sul proprio sito Web. Fare clic sul collegamento applicabile per visualizzare maggiori dettagli sulla sintassi per un particolare fornitore.
I DBMS coperti sono MySQL, SQL Server, PostgreSQL e Oracle Database.
MySQL
Dal manuale di riferimento di MySQL 5.7:
INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
[INTO] tbl_name
[PARTITION (partition_name,...)]
[(col_name,...)]
{VALUES | VALUE} ({expr | DEFAULT},...),(...),...
[ ON DUPLICATE KEY UPDATE
col_name=expr
[, col_name=expr] ... ] Oppure:
INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
[INTO] tbl_name
[PARTITION (partition_name,...)]
SET col_name={expr | DEFAULT}, ...
[ ON DUPLICATE KEY UPDATE
col_name=expr
[, col_name=expr] ... ] Oppure:
INSERT [LOW_PRIORITY | HIGH_PRIORITY] [IGNORE]
[INTO] tbl_name
[PARTITION (partition_name,...)]
[(col_name,...)]
SELECT ...
[ ON DUPLICATE KEY UPDATE
col_name=expr
[, col_name=expr] ... ] SQL Server
Dal riferimento Transact-SQL:
[ WITH <common_table_expression> [ ,...n ] ]

[ TOP ( expression ) [ PERCENT ] ]
[ INTO ]
{ <object> | rowset_function_limited
[ WITH ( <Table_Hint_Limited> [ ...n ] ) ]

}
}
}
[;]
<object> ::=

}
[; ] PostgreSQL
Dal manuale di PostgreSQL 9.5:
[ WITH [ RECURSIVE ] with_query [, ...] ]
INSERT INTO table_name [ AS alias ] [ ( column_name [, ...] ) ]
{ DEFAULT VALUES | VALUES ( { expression | DEFAULT } [, ...] ) [, ...] | query }
[ ON CONFLICT [ conflict_target ] conflict_action ]
[ RETURNING * | output_expression [ [ AS ] output_name ] [, ...] ]
where conflict_target can be one of:
( { index_column_name | ( index_expression ) } [ COLLATE collation ] [ opclass ] [, ...] ) [ WHERE index_predicate ]
ON CONSTRAINT constraint_name
and conflict_action is one of:
DO NOTHING
DO UPDATE SET { column_name = { expression | DEFAULT } |
( column_name [, ...] ) = ( { expression | DEFAULT } [, ...] ) |
( column_name [, ...] ) = ( sub-SELECT )
} [, ...]
[ WHERE condition ] Database Oracle

Il INSERTO istruzione inserisce nuove righe in una tabella. Puoi inserire una o più righe specificate da espressioni di valore oppure zero o più righe risultanti da una query.
