How to modify tablename with plugin and callback?

[so2bin]

Your Question

• I want to change all the SQL's table names with a fixed prefix before the process. I don't know how to do this with the *gorm.DB object like this https://gorm.io/zh_CN/docs/hooks.html#%E4%BF%AE%E6%94%B9%E5%BD%93%E5%89%8D%E6%93%8D%E4%BD%9C
• Is there any example or document can help me to resolve this problem?
• Or any document about the clause introduction?

What I Want

• Now I am using the TiDB sqlparser github.com/pingcap/tidb/pkg/parser to modify the SQL, for example:

type MirrorTableModifier struct {
	tblNameMap map[string]string
}

func (m *MirrorTableModifier) Enter(in ast.Node) (ast.Node, bool) {
	switch node := in.(type) {
	case *ast.TableName:
		if modifyName, ok := m.tblNameMap[node.Name.String()]; ok {
			node.Name = model.NewCIStr(modifyName)  // modify table name here
		}
	}
	return in, false
}

func (m *MirrorTableModifier) Leave(in ast.Node) (ast.Node, bool) {
	return in, true
}

• So how can I use this sqlparser together with gorm callback?
