RWDBTable is a base class from which a family of classes derive. RWDBTable represents a table of information whose actual location is transparent. The data may reside in a database table or in program memory, or may be an SQL table expression, that is, a derived table or collection of rows returned from a database query. The types of tables to which RWDBTable provides an interface are:
RWDBTable is designed around the Interface/Implementation paradigm. An RWDBTable instance is an interface to a reference-counted implementation; copy constructors and assignment operators produce additional references to a shared implementation. An RWDBTable implementation is a base class from which a family of table implementations is derived. Each implementation except that of a derived table and RWDBMemTable is in turn a base class from which a family of database-specific table implementations derive.
| enum RWDBTable::CacheType |
A class-scoped enum containing the cache types.
| Enumerator | |
|---|---|
| Local |
Clears self's cache. Cached data for an RWDBTable consists of the schema, the state of the exists flag and whether self is a view or not. Note that data about primary keys, foreign keys, referred-to-by keys, check constraints, unique constraints and identity column, if stored in schema, is also cleared. |
| All |
Clears cached data in self and in the cache manager derived from RWDBCacheManager, if there is one. Cached data for an RWDBTable consists of schema, the state of the exists flag and whether self is a view or not. Note that data about primary keys, foreign keys, referred-to-by keys, check constraints, unique constraints and identity column, if stored in schema, is also cleared. |
| enum RWDBTable::Metadata |
A class-scoped enum containing the metadata types.
| RWDBTable::RWDBTable | ( | ) |
The default constructor creates an RWDBTable whose status is RWDBStatus::notInitialized. This constructor is provided as a convenience, for example, for declaring an array of RWDBTable objects. Usable RWDBTable objects are obtained from RWDBDatabase and RWDBResult.
| RWDBTable::RWDBTable | ( | const RWDBTable & | table | ) |
Copy constructor. Self shares an implementation with table.
| void RWDBTable::acquire | ( | void | ) | const |
Attempts to acquire the internal mutex lock. If the mutex is already locked by another thread, the function blocks until the mutex is released. This function can be called from a const object.
| RWDBStatus RWDBTable::addColumn | ( | const RWDBColumn & | column | ) |
Uses a default database connection to execute the database-specific equivalent of the SQL statement:
where <table> is the database table represented by self, and <column> is defined by the given column. If successful, calls fetchSchema() so that self's schema remains consistent with the database. You can check the return value's isValid() method to determine whether the operation succeeded. If self is not a database table, the returned status is RWDBStatus::invalidUsage.

| RWDBStatus::ErrorHandler RWDBTable::errorHandler | ( | ) | const |
Returns the error handler attached to self.
| bool RWDBTable::exists | ( | bool | forceLookup = false | ) |
If self is a database table, returns true if the table exists in the database, otherwise returns false. If self is a derived table, returns true if the schema of the result set of the SQL SELECT statement that self represents can be fetched, otherwise returns false. If self is a memory table, always returns false. If self is a result table, returns true if an RWDBReader has not yet been obtained to read self, otherwise returns false.
To determine whether or not a database table exists, the DB Interface Module uses a default connection to query the database. To determine whether or not a derived table exists, the DB Interface Module uses a default connection to fetch the schema of the encapsulated RWDBSelectorBase instance. If no schema can be obtained, returns false. Otherwise, self's RWDBSchema is populated with the result of the query, and returns true.
By default, multiple calls to a database table's or derived table's exists() method always return the same result; the database is only queried on the first call. This behavior can be overridden by forceLookup, which, if true, forces the database to be queried.

| RWDBInserter RWDBTable::inserter | ( | size_t | cache = 0 | ) | const |
Produces an RWDBInserter that encapsulates the SQL statement:
where <table> is represented by self. The actual values must be added to the inserter later. If self is not a database table, returns an RWDBInserter with a status of RWDBStatus::noInserter.
0 or 1 creates a non-cached inserter (the default), while any larger value creates a cache that collects the specified number of rows before placing them in the table. It is important to understand that using a cache means executing an insert does not necessary immediately place the data in the table. The DB Interface Module User Guide includes a discussion of RWDBInserter caching. You should also check your Access Module documentation for limitations and warnings. | RWDBInserter RWDBTable::inserter | ( | const RWDBSelector & | selector | ) | const |
Produces an RWDBInserter that encapsulates the SQL statement:
where <table> is represented by self. The select-statement is encapsulated by the given selector. This method is equivalent to database.inserter(*this, selector). If self is not a database table, returns an RWDBInserter with a status of RWDBStatus::noInserter.
| RWDBInserter RWDBTable::inserter | ( | const RWDBCompoundSelector & | selector | ) | const |
Produces an RWDBInserter that encapsulates the SQL statement:

| RWDBInserter RWDBTable::inserter | ( | const RWDBSchema & | columnList, |
| size_t | cache = 0 |
||
| ) | const |
Produces an RWDBInserter that encapsulates the SQL statement:
where <table> is represented by self. The names of the column entries in columnList are used to build up the column-name list. If self is not a database table, returns an RWDBInserter with a status of RWDBStatus::noInserter.

| bool RWDBTable::isReady | ( | ) | const |
Returns true if the object is in ready state, indicating that accessing the object will not block. Accessing a nonready object may potentially block.
| bool RWDBTable::isValid | ( | ) | const |
Returns true if the status of self is RWDBStatus::ok, otherwise returns false.
| bool RWDBTable::isView | ( | ) | const |
Returns true if self represents a database view, otherwise returns false. More specifically:
false.| bool RWDBTable::isView | ( | const RWDBConnection & | conn | ) | const |
Returns true if self represents a database view, otherwise returns false. More specifically:
false.| RWCString RWDBTable::name | ( | ) | const |

Changes the name of self to name. Returns a reference to self.
| size_t RWDBTable::numberOfColumns | ( | ) | const |
Returns the number of columns in self's schema.
Assignment operator. Self shares an implementation with table.
| RWDBColumn RWDBTable::operator[] | ( | const RWCString & | name | ) | const |
Returns a deep copy of the first RWDBColumn in self's schema whose name matches the given name. The RWDBColumn returned is associated with self, that is, the table() method of the returned RWDBColumn returns this table. If no matching column is found, returns a new RWDBColumn instance whose name is set to name and status is RWDBStatus::ok. This is used with RWDBSelector to build up selectors and criteria without requiring an application to fetch the schema of a table. For example:
| RWDBColumn RWDBTable::operator[] | ( | size_t | position | ) | const |
Returns a deep copy of the RWDBColumn in self's schema at the given position. The RWDBColumn returned is associated with self. If no matching column is found, returns an RWDBColumn whose status is RWDBStatus::columnNotFound. A deep copy is made so that the application can modify the returned RWDBColumn without modifying self's schema.
| RWDBPrimaryKey RWDBTable::primaryKey | ( | const RWDBConnection & | conn | ) |
Calls RWDBCacheManager::getPrimaryKey() const. If successful, updates self's schema with the return value. Otherwise, uses conn to fetch the primary key associated with self. If successful, updates self's schema with the return value and calls RWDBCacheManager::setPrimaryKey(const RWDBPrimaryKey&). An empty RWDBPrimaryKey indicates there is no primary key associated with self.
| RWDBPrimaryKey RWDBTable::primaryKey | ( | ) |
Calls RWDBCacheManager::getPrimaryKey() const. If successful, updates self's schema with the return value. Otherwise, uses a default connection to fetch the primary key associated with self. If successful, updates self's schema with the return value and calls RWDBCacheManager::setPrimaryKey(const RWDBPrimaryKey&). An empty RWDBPrimaryKey indicates there is no primary key associated with self. You can check the status of the returned RWDBPrimaryKey to determine whether the operation succeeded with the method RWDBPrimaryKey::status().isValid().
| RWDBReader RWDBTable::reader | ( | size_t | cacheSize = 0 | ) | const |
Produces an RWDBReader that can be used to read data from self one row at a time. If self is a derived table, the RWDBReader produced reads rows of the result set from execution of the SQL self represents. If self is an RWDBTPtrMemTable, returns an RWDBReader with a status of RWDBStatus::noReader. RWDBTPtrMemTable does not support readers.
Unless self is a memory table, a query is executed using a default database connection, returning a reader for the contents of the table. The reader holds the connection until the reader is destroyed.
0 (the default) results in a Rogue Wave-determined acceptable default cache size for a given access module. Specify a positive numeric value to specify your own cache size. The DB Interface Module User Guide includes a discussion of RWDBReader caching. You should also check your Access Module documentation for limitations and warnings. | RWDBReader RWDBTable::reader | ( | const RWDBConnection & | connection, |
| size_t | cacheSize = 0 |

| RWDBForeignKeyList & | keyList | ||
| ) |
Calls RWDBCacheManager::getReferredToBy() const. If successful, appends to keyList all foreign keys that refer to self. Otherwise, uses conn to append to keyList all foreign keys that refer to self. If successful, calls RWDBCacheManager::setReferredToBy(const RWDBForeignKeyList&). You can check the return value's isValid() method to determine whether the operation succeeded.
| RWDBStatus RWDBTable::referredToBy | ( | RWDBForeignKeyList & | keyList | ) |

Returns a shallow copy of self's RWDBSchema.
| void RWDBTable::setErrorHandler | ( | RWDBStatus::ErrorHandler | errorHandler | ) |
Installs errorHandler as self's error handler. The supplied handler is inherited by all objects produced by self. By default an RWDBTable error handler is inherited from the object that produced it. This method overwrites the default.
| RWDBStatus RWDBTable::status | ( | ) | const |
Returns the status of self.
| RWCString RWDBTable::tag | ( | ) | const |
Returns self's tag. A table's tag is an alias generated by the DB Interface Module for use in SQL queries.
