嗨社区,
我遇到了Symfony 2和Doctrine与MSSQL数据库的问题。在" php app / console doctrine:database:create"和" php app / console doctrine:schema:create"一切都很好。但是在" php app / console doctrine:schema:update"在错误:
之后,ORM-Mapper或实体显示中没有任何更改[Doctrine\DBAL\DBALException]
An exception occurred while executing 'ALTER TABLE product DROP CONSTRAINT DF_D34A04AD_A5D6E63E':
SQLSTATE[42000]: [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]DF_D34A04AD_A5D6E63E is not a restriction.
请帮助
当我从名为" DF__product__timesta__38996AB5"的表中手动删除限制时,它出现了一个新的错误:
[Doctrine\DBAL\DBALException]
An exception occurred while executing 'ALTER TABLE product ALTER COLUMN timestamp DATETIME DEFAULT CURRENT_TIMESTAMP':
SQLSTATE[42000]: [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Incorrect syntax near the DEFAULT keyword.
请帮助

这不是将默认值添加到列的有效语法:
ALTER TABLE product ALTER COLUMN timestamp DATETIME DEFAULT CURRENT_TIMESTAMP
你应该使用
ALTER TABLE product ADD DEFAULT CURRENT_TIMESTAMP
FOR [timestamp]
或者您可以使用约束名称:
ALTER TABLE product ADD CONSTRAINT DF_TIMESTAMP DEFAULT CURRENT_TIMESTAMP
FOR [timestamp]
您收到的第一个错误很奇怪,因为当您尝试删除不存在的约束时,您应该
'DF_D34A04AD_A5D6E63E'不是约束。
原因是您使用了错误的约束名称。它似乎不会自动生成默认约束名称,因为它使用了生成的表名+字段名。因此,请再次检查约束名称。
