Package ModSQL

Interface Summary

Aggregate	Refinement of Function interface for aggregate functions.
DatabaseIndex	Interface to be implemented by table indices.
DatabaseManager	Interface to be implemented by database managers.
DatabaseTable	Interface to be implemented by classes representing database tables.
DatabaseTableBase	Base interface for DatabaseTable and DatabaseIndex.
Function	This interface is at the root of all single-valued SQL expressions (including row constructors).
FunctionProvider	Classes implementing this interface provide Function objects matching a particular String description on demand.
Query	Interface for the various SQL query classes.
RowConstructor	A row constructor (in SQL speak) is a single row of one or more columns.
Table	A table is zero or more rows.

Class Summary

AbstractAggregate	Abstract implementation of Aggregate to simplify the implementation of real aggregate functions.
AbstractFunction	Abstract implementation of Function to simplify the implementation of real functions.
Aggregate_Count	Implementation of SQL aggregate function COUNT().
Aggregate_Math	Implementation of SQL aggregate functions SUM(), AVG() and STDEV().
Aggregate_MinMax	Implementation of SQL aggregate functions MIN() and MAX().
ColumnValue	This object is used to retrieve the value of specific of a database table.
Connection	A Connection represents a session with a specific database.
Create	Create will parse a CREATE SQL statement.
DatabaseMetaData	This class provides information about the database as a whole.
Delete	Delete will parse and execute an SQL DELETE query.
Driver	JDBC Driver object.
DriverConfig	Configuration data for ModSQL.
Drop	Drop will parse a DROP sql statement.
EndOfTable	A throwable to indicate that the end of a table has been reached.
Expression	Abstract class with static methods for parsing SQL expressions.
Function_Math	This class implements standard SQL math functions: ABS, CEIL, FLOOR, GREATEST, LEAST, MOD, POWER, ROUND, SIGN, and SQRT.
Function_NVL	SQL function for NVL (null value substitution function).
Function_String	SQL function for string operations.
IndexTable	Abstract base class for built-in table indexing classes.
IndexTable_Hash	Implementation of DatabaseTable for tables that are indexed by the ModSQL driver using a hash table.
IndexTable_Sort	Implementation of DatabaseTable for tables that are indexed by the ModSQL driver.
IndexTableEntry	Column data object and table rowset combined.
IndexTableRowset	Each object describes a set of rows in a table.
IndirectFunction	Wrapper for some other function.
Insert	Insert parses and executes an SQL INSERT query.
Literal	Wrapper for literal values.
LiteralRow	This class represents a literal row constructor.
LiteralTable	A literal table is a list of rows consisting of RowConstructor or Function objects.
MetaManager	DatabaseManager that can be used to combine multiple DatabaseManagers into one metadatabase.
NumberMath	A class very much like java.lang.Math, but for doing math on Number objects.
Operator	Abstract implementation of Function to simplify the implementation of operators.
Operator_Add	SQL operator "+".
Operator_Compare	SQL comparison operators.
Operator_Concat	SQL operator "||".
Operator_Divide	SQL operator "/".
Operator_Exists	Implementation of EXISTS operator.
Operator_In	SQL comparison operators with a table on the RHS.
Operator_Is	SQL operator IS.
Operator_Like	SQL operator LIKE.
Operator_Logical	SQL operators AND and OR.
Operator_Multiply	SQL operator "*".
Operator_Negate	SQL operator "-".
Operator_Not	SQL operator NOT.
PreparedStatement	An object that represents a precompiled SQL statement.
ResultSet	A ResultSet provides access to a table of data.
ResultSetMetaData	A ResultSetMetaData object can be used to find out about the types and properties of the columns in a ResultSet.
Select	Class to parse and execute an SQL SELECT statement.
SelectTable	Wrapper for a Select object to make it look like a DatabaseTable.
TableReader	Keeps track of open tables, referenced columns, and current row being read from joined table.
Update	Update will parse and execute an SQL UPDATE query.

Exception Summary

DatabaseException	An exception for use by classes implementing DatabaseManager, DatabaseTable, and DatabaseIndex to represent database errors that may occur.
