Выше приведено много хороших сценариев для генерации операторов вставки, но я попытался сделать один из своих собственных, чтобы сделать его максимально удобным для пользователя, а также иметь возможность выполнять операторы UPDATE. + упаковать результат для файлов .sql, которые можно сохранить по дате.
Он принимает в качестве входных данных ваш обычный оператор SELECT с предложением WHERE, затем выводит список операторов вставки и операторов обновления. Вместе они образуют нечто вроде IF NOT EXISTS () INSERT ELSE UPDATE Это также удобно, когда есть не обновляемые столбцы, которые необходимо исключить из окончательного оператора INSERT / UPDATE.
Еще одна вещь, которую может сделать приведенный ниже скрипт: он может даже обрабатывать INNER JOINs с другими таблицами в качестве оператора ввода для хранимого процесса. Он может быть полезен как инструмент управления релизами бедного человека, который находится у вас под рукой, когда вы весь день печатаете операторы SQL SELECT.
оригинальный пост: создание оператора UPDATE в SQL Server для конкретной таблицы
CREATE PROCEDURE [dbo].[sp_generate_updates] (
@fullquery nvarchar(max) = '',
@ignore_field_input nvarchar(MAX) = '',
@PK_COLUMN_NAME nvarchar(MAX) = ''
)
AS
SET NOCOUNT ON
SET QUOTED_IDENTIFIER ON
/*
-- For Standard USAGE: (where clause is mandatory)
EXEC [sp_generate_updates] 'select * from dbo.mytable where mytext=''1'' '
OR
SET QUOTED_IDENTIFIER OFF
EXEC [sp_generate_updates] "select * from dbo.mytable where mytext='1' "
-- For ignoring specific columns (to ignore in the UPDATE and INSERT SQL statement)
EXEC [sp_generate_updates] 'select * from dbo.mytable where 1=1 ' , 'Column01,Column02'
-- For just updates without insert statement (replace the * )
EXEC [sp_generate_updates] 'select Column01, Column02 from dbo.mytable where 1=1 '
-- For tables without a primary key: construct the key in the third variable
EXEC [sp_generate_updates] 'select * from dbo.mytable where 1=1 ' ,'','your_chosen_primary_key_Col1,key_Col2'
-- For complex updates with JOINED tables
EXEC [sp_generate_updates] 'select o1.Name, o1.category, o2.name+ '_hello_world' as #name
from overnightsetting o1
inner join overnightsetting o2 on o1.name=o2.name
where o1.name like '%appserver%'
(REMARK about above: the use of # in front of a column name (so #abc) can do an update of that columname (abc) with any column from an inner joined table where you use the alias #abc )
-------------README for the deeper interested person:
Goal of the Stored PROCEDURE is to get updates from simple SQL SELECT statements. It is made ot be simple but fast and powerfull. As always => power is nothing without control, so check before you execute.
Its power sits also in the fact that you can make insert statements, so combined gives you a "IF NOT EXISTS() INSERT " capability.
The scripts work were there are primary keys or identity columns on table you want to update (/ or make inserts for).
It will also works when no primary keys / identity column exist(s) and you define them yourselve. But then be carefull (duplicate hits can occur). When the table has a primary key it will always be used.
The script works with a real temporary table, made on the fly (APPROPRIATE RIGHTS needed), to put the values inside from the script, then add 3 columns for constructing the "insert into tableX (...) values ()" , and the 2 update statement.
We work with temporary structures like "where columnname = {Columnname}" and then later do the update on that temptable for the columns values found on that same line.
example "where columnname = {Columnname}" for birthdate becomes "where birthdate = {birthdate}" an then we find the birthdate value on that line inside the temp table.
So then the statement becomes "where birthdate = {19800417}"
