Along with the social and the rapid development of modern information technology, people on the database database application with dependence is growing, the emergence of the database to people's life and work has brought great convenience, but is followed by more and more security problems, should not be ignored. When our database data is damage, leakage and change, will work to our life bring inconvenience. But the database system itself has certain security protection measures, to a certain extent, helps us to protect the security of database data, but even so, in a SQL database in use process, will appear this or that kind of security issues, when unpredictable security threat comes, we may be effective ways to take the initiative to prevent these safety problems, when we know the correct way, and can effectively, protect us in the true sense of the database security, so the security of the SQL database problem still cannot be ignored. Based on the above, this article will focus on the SQL database security problems is studied and discussed.

With the highly development in social and internet techonoly, the demand for digital database usage and its application fromt the people are also increased. The Ditigal database(DDB)'s emergence has provided our daily life and works with lots of conveniences but on the other hand, the assoicated security issues from the DDB ought to be taken care of. What if our DDB are damaged, modified and leaked, these will certianly affect our work life. Fortunately, our DDB system has its own security measurement and protection against these threats. The use of SQL database may still have some security issues, if there is any abrupt threat in security, we have to follow an effective and proactive security measurement to protect the system, and when we derived such feasible way to do so then it is a affirmed security measurement and procedures for the DDB. As such, SQL DB security issues are important for us.
This article is based on the above issues in SQL digital database security and provides us with the analysis and study of it.
