ExpandDataSourceGlob is a utility function that expands a tree.TablePattern into a list of object names.

FindTableColumnByName returns the ordinal of the non-mutation column having the given name, if one exists in the given table.

FormatSequence nicely formats a catalog sequence using a treeprinter for debugging and testing.

FormatTable nicely formats a catalog table using a treeprinter for debugging and testing.

FormatView nicely formats a catalog view using a treeprinter for debugging and testing.

FormatZone nicely formats a catalog zone using a treeprinter for debugging and testing.

IsMutationColumn is a convenience function that returns true if the column at the given ordinal position is a mutation column.

IsMutationIndex is a convenience function that returns true if the index at the given ordinal position is a mutation index.

ResolveTableIndex resolves a TableIndexName.

PrimaryIndex selects the primary index of a table when calling the Table.Index method.

CheckConstraint contains the SQL text and the validity status for a check constraint on a table.

FamilyColumn describes a single column that is part of a family definition.

Catalog is an interface to a database catalog, exposing only the information needed by the query optimizer.

Column is an interface to a table column, exposing only the information needed by the query optimizer.

Constraint governs placement of range replicas on nodes.

ConstraintSet is a set of constraints that apply to a range, restricting which nodes can host that range or stating which nodes are preferred as the leaseholder.

DataSource is an interface to a database object that provides rows, like a table, a view, or a sequence.

Family is an interface to a table column family, exposing only the information needed by the query optimizer.

ForeignKeyConstraint represents a foreign key constraint.

Index is an interface to a database index, exposing only the information needed by the query optimizer.

Object is implemented by all objects in the catalog.

ReplicaConstraints is a set of constraints that apply to one or more replicas of a range, restricting which nodes can host that range.

Schema is an interface to a database schema, which is a namespace that contains other database objects, like tables and views.

Sequence is an interface to a database sequence.

Table is an interface to a database table, exposing only the information needed by the query optimizer.

TableStatistic is an interface to a table statistic.

View is an interface to a database view, exposing only the information needed by the query optimizer.

Zone is an interface to zone configuration information used by the optimizer.

DataSourceName is an alias for tree.TableName, and is used for views and sequences as well as tables.

IndexOrdinal identifies an index (in the context of a Table).

SchemaName is an alias for tree.TableNamePrefix, since it consists of the catalog + schema name.

StableID permanently and uniquely identifies a catalog object (table, view, index, column, etc.) within its scope: data source StableID: unique within database index StableID: unique within table column StableID: unique within table If a new catalog object is created, it will always be assigned a new StableID that has never, and will never, be reused by a different object in the same scope.
