To limit permissions on a table you need to use REVOKE:

要限制表的权限,您需要使用REVOKE:

The REVOKE statement enables system administrators to revoke privileges from MySQL accounts. Each account name uses the format described in Section 6.2.3, “Specifying Account Names”.

REVOKE语句使系统管理员可以撤消MySQL帐户的权限。每个帐户名称使用第6.2.3节“指定帐户名称”中所述的格式。

Thanks for help. I solved it programmatically. In my entity class for read-only table I inserted @ReadOnly annotation and :

感谢帮助。我以编程方式解决了它。在我的只读表实体类中,我插入了@ReadOnly注释,并且:

@OneToMany(targetEntity=Catalog.class, mappedBy="category", cascade={CascadeType.ALL},   fetch = FetchType.EAGER)
private List<Catalog> catalog;

and in target entity:

在目标实体中:

@ManyToOne()
@JoinColumn(name="cname", referencedColumnName="name")
private Category category;
