この記事では、SQL UPDATE
を一覧表示します さまざまなデータベース管理システム(DBMS)によって実装される構文。構文は、各ベンダーがWebサイトにリストしているとおりに正確にリストされています。特定のベンダーの構文の詳細を表示するには、該当するリンクをクリックしてください。
対象となるDBMSは、MySQL、SQL Server、PostgreSQL、およびOracleデータベースです。
MySQL
MySQL5.7リファレンスマニュアルから。
単一テーブル構文:
UPDATE [LOW_PRIORITY] [IGNORE]table_reference
SETcol_name1
={expr1
|DEFAULT} [,col_name2
={expr2
|DEFAULT}] ... [WHEREwhere_condition
] [ORDER BY ...] [LIMITrow_count
]
複数テーブルの構文:
UPDATE [LOW_PRIORITY] [IGNORE]table_references
SETcol_name1
={expr1
|DEFAULT} [,col_name2
={expr2
|DEFAULT}] ... [WHEREwhere_condition
]
SQL Server
Transact-SQLリファレンスから:
[ WITH <common_table_expression> [...n] ] UPDATE [ TOP ( expression ) [ PERCENT ] ] { { table_alias | <object> | rowset_function_limited [ WITH ( <Table_Hint_Limited> [ ...n ] ) ] } | @table_variable } SET { column_name = { expression | DEFAULT | NULL } | { udt_column_name.{ { property_name = expression | field_name = expression } | method_name ( argument [ ,...n ] ) } } | column_name { .WRITE ( expression , @Offset , @Length ) } | @variable = expression | @variable = column = expression | column_name { += | -= | *= | /= | %= | &= | ^= | |= } expression | @variable { += | -= | *= | /= | %= | &= | ^= | |= } expression | @variable = column { += | -= | *= | /= | %= | &= | ^= | |= } expression } [ ,...n ] [ <OUTPUT Clause> ] [ FROM{ <table_source> } [ ,...n ] ] [ WHERE { <search_condition> | { [ CURRENT OF { { [ GLOBAL ] cursor_name } | cursor_variable_name } ] } } ] [ OPTION ( <query_hint> [ ,...n ] ) ] [ ; ] <object> ::= { [ server_name . database_name . schema_name . | database_name .[ schema_name ] . | schema_name . ] table_or_view_name}
PostgreSQL
PostgreSQL 9.5マニュアルから:
[ WITH [ RECURSIVE ] with_query [, ...] ] UPDATE [ ONLY ] table_name [ * ] [ [ AS ] alias ] SET { column_name = { expression | DEFAULT } | ( column_name [, ...] ) = ( { expression | DEFAULT } [, ...] ) | ( column_name [, ...] ) = ( sub-SELECT ) } [, ...] [ FROM from_list ] [ WHERE condition | WHERE CURRENT OF cursor_name ] [ RETURNING * | output_expression [ [ AS ] output_name ] [, ...] ]
