Constructor Detail

MockCatalogReader

public MockCatalogReader(RelDataTypeFactory typeFactory)

Creates a MockCatalogReader.

Parameters:

typeFactory - Type factory

MockCatalogReader

protected MockCatalogReader(RelDataTypeFactory typeFactory,
                            boolean dummy)

Creates a MockCatalogReader but does not initialize.

Protected constructor for use by subclasses, which must call init() at the end of their public constructor.

Parameters:

typeFactory - Type factory

dummy - Dummy parameter to distinguish from public constructor

Method Detail

init

protected void init()

Initializes this catalog reader.

registerTable

protected void registerTable(MockCatalogReader.MockTable table)

registerSchema

protected void registerSchema(MockCatalogReader.MockSchema schema)

getTable

public SqlValidatorTable getTable(String[] names)

Description copied from interface: SqlValidatorCatalogReader

Finds a table with the given name, possibly qualified.

Specified by:

getTable in interface SqlValidatorCatalogReader

Parameters:

names - Name of table

Returns:

named table, or null if not found

getNamedType

public RelDataType getNamedType(SqlIdentifier typeName)

Description copied from interface: SqlValidatorCatalogReader

Finds a user-defined type with the given name, possibly qualified.

NOTE jvs 12-Feb-2005: the reason this method is defined here instead of on RelDataTypeFactory is that it has to take into account context-dependent information such as SQL schema path, whereas a type factory is context-independent.

Specified by:

getNamedType in interface SqlValidatorCatalogReader

Parameters:

typeName - Name of type

Returns:

named type, or null if not found

getAllSchemaObjectNames

public List<SqlMoniker> getAllSchemaObjectNames(List<String> names)

Description copied from interface: SqlValidatorCatalogReader

Gets schema object names as specified. They can be schema or table object. If names array contain 1 element, return all schema names and all table names under the default schema (if that is set) If names array contain 2 elements, treat 1st element as schema name and return all table names in this schema

Specified by:

getAllSchemaObjectNames in interface SqlValidatorCatalogReader

Parameters:

names - the array contains either 2 elements representing a partially qualified object name in the format of 'schema.object', or an unqualified name in the format of 'object'

Returns:

the list of all object (schema and table) names under the above criteria

getSchemaName

public String getSchemaName()

Description copied from interface: SqlValidatorCatalogReader

Returns the name of the current schema.

Specified by:

getSchemaName in interface SqlValidatorCatalogReader

Returns:

name of the current schema
