type InfoSchema interface {
SchemaByName(schema model.CIStr) (*model.DBInfo, bool)
SchemaExists(schema model.CIStr) bool
TableByName(schema, table model.CIStr) (table.Table, error)
TableExists(schema, table model.CIStr) bool
ColumnByName(schema, table, column model.CIStr) (*model.ColumnInfo, bool)
ColumnExists(schema, table, column model.CIStr) bool
IndexByName(schema, table, index model.CIStr) (*model.IndexInfo, bool)
SchemaByID(id int64) (*model.DBInfo, bool)
TableByID(id int64) (table.Table, bool)
ColumnByID(id int64) (*model.ColumnInfo, bool)
ColumnIndices(id int64) []*model.IndexInfo
AllSchemaNames() []string
AllSchemas() []*model.DBInfo
Clone() (result []*model.DBInfo)
SchemaTables(schema model.CIStr) []table.Table
}
InfoSchema is the interface used to retrieve the schema information. It works as a in memory cache and doesn't handle any schema change. InfoSchema is read-only, and the returned value is a copy.
