Create a batch file that executes the required scripts against different SQL Server instances. The batch file should look like this:
:CONNECT <server1>\,<instance1>
--SQL1 to execute
GO
:CONNECT <server2>\,<instance2>
--SQL2 to execute
GO
Execute the batch file using SQLCMD:
SQLCMD –I [image] \Scripts\BatchMultiple.bat
A disadvantage of this method is that it requires numerous manual and time-consuming actions, which are very error prone. Each time when new scripts are executed, the batch file must be modified or a new one has to be created. / comments

Restore it from the backup of the database.To avoid such problems in future try to implement this https://docsbay.net/sql-server-ddl-triggers-to-track-all-database-changes . It is a short term fix if you don't have super duper source control system's. / comments

MySQL is returning that error (most likely) because there is no unique index defined on the id column. (MySQL requires that there be a unique index. The other possibility, which you would have already figured out, is that there can be only one column defined as AUTO_INCREMENT within the table.) To get that column to be an AUTO_INCREMENT, you can add either a UNIQUE constraint or a PRIMARY KEY constraint on the id column. For example: ALTER TABLE `blog` ADD CONSTRAINT `blog_ux` UNIQUE (`id`) ;(Note that this statement will return an error if any duplicate values exist for the id column.) Alternatively, you can make the id column the PRIMARY KEY of the table (if the table doesn't already have a PRIMARY KEY constraint defined). ALTER TABLE `blog` ADD PRIMARY KEY (`id`) ;(Note that this statement will return an error if any duplicate value exist for the id column, OR if there are any NULL values stored in that column, of if there is already a PRIMARY KEY constraint defined on the table.) If it still doesn't work,try this: https://docsbay.net/mysql-php-newbie Or try this: CREATE TABLE `testing` ( `id` INT NOT NULL AUTO_INCREMENT,
`date` DATE NOT NULL,
`text_1` TEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`text_2` TEXT CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
PRIMARY KEY (`id`)
