+{
+  Simple classes for using SQLite's exec and get_table.
+
+  TSQLiteDatabase wraps the calls to open and close an SQLite database.
+  It also wraps SQLite_exec for queries that do not return a result set
+
+  TSQLiteTable wraps execution of SQL query.
+  It run query and read all returned rows to internal buffer.
+  It allows accessing fields by name as well as index and can move through a
+  result set forward and backwards, or randomly to any row.
+
+  TSQLiteUniTable wraps execution of SQL query.
+  It run query as TSQLiteTable, but reading just first row only!
+  You can step to next row (until not EOF) by 'Next' method.
+  You cannot step backwards! (So, it is called as UniDirectional result set.)
+  It not using any internal buffering, this class is very close to Sqlite API.
+  It allows accessing fields by name as well as index on actual row only.
+  Very good and fast for sequentional scanning of large result sets with minimal
+    memory footprint.
+
+  Warning! Do not close TSQLiteDatabase before any TSQLiteUniTable,
+    because query is closed on TSQLiteUniTable destructor and database connection
+    is used during TSQLiteUniTable live!
+
+  SQL parameter usage:
+    You can add named parameter values by call set of AddParam* methods.
+    Parameters will be used for first next SQL statement only.
+    Parameter name must be prefixed by ':', '$' or '@' and same prefix must be
+    used in SQL statement!
+    Sample:
+      table.AddParamText(':str', 'some value');
+      s := table.GetTableString('SELECT value FROM sometable WHERE id=:str');
+
+   Notes from Andrew Retmanski on prepared queries
+   The changes are as follows:
+
+   SQLiteTable3.pas
+   - Added new boolean property Synchronised (this controls the SYNCHRONOUS pragma as I found that turning this OFF increased the write performance in my application)
+   - Added new type TSQLiteQuery (this is just a simple record wrapper around the SQL string and a TSQLiteStmt pointer)
+   - Added PrepareSQL method to prepare SQL query - returns TSQLiteQuery
+   - Added ReleaseSQL method to release previously prepared query
+   - Added overloaded BindSQL methods for Integer and String types - these set new values for the prepared query parameters
+   - Added overloaded ExecSQL method to execute a prepared TSQLiteQuery
+
+   Usage of the new methods should be self explanatory but the process is in essence:
+
+   1. Call PrepareSQL to return TSQLiteQuery 2. Call BindSQL for each parameter in the prepared query 3. Call ExecSQL to run the prepared query 4. Repeat steps 2 & 3 as required 5. Call ReleaseSQL to free SQLite resources
+
+   One other point - the Synchronised property throws an error if used inside a transaction.

+5 June 2008
+Updated DLL to version 3.5.9 (built with MSVC 6.0)
+Added code from Andrew Retmanski to support prepared queries (see comments in SQLIteTable3.pas
+Lukas added support for named parameters - see comments in code
+User nebula enhanced error message; also modified code to call sqlite3_reset before checking error message
+
+
+27 Aug 2007
+Amended TSQLiteDatabase constructor to convert filename to UTF8,for compatibility with latest SQLite3 DLL.
+
+Updated DLL to version 3.4.2 (built with MSVC 6.0).
+
+14 Aug 2005
+
+The following changes were made by Lukas Gebauer (geby@volny.cz). In addition, some changes from a previous D5-compatible version were merged, and the supplied sqlite3.dll is updated to version 3.2.2
+
+Notes from Lukas:
+
+- added support for delphi 4+
+
+- datatype constants matches SQlite datatypes contants. (otherwise in some situations you got bad column datatype!)
+
+- removed dependency on strutils
+
+- code is reformatted to better look (official borland formatting rules)
+
+- added some pragma's after database is open (temp is in memory)
+
+- TSQLiteDatabase.GetTableValue(const SQL: string): int64 for easy call of SQL commands what returning one number only. (like select
+count(*)...)
+
+- TSQLiteDatabase.GetTableString(const SQL: string): String for easy call of SQL commands what returning one string only. (like PRAGMA
+integrity_check)
+
+- TSQLiteDatabase.SetTimeout(Value: integer); you can set timeout for accessing to some table. Good for database sharing!
+
+- TSQLiteDatabase.version: string; returns SQLITE version string
+
+- removed bool fieldtype (it is not natural SQLite3 type)
+
+- fild type detection by Sqite3_columnType knows REAL too.
+
+- integer filedtype is based on Int64
+
+- GetFields can get data from any supported fieldtype
+
+- changed some integers to cardinal for avoid signed and unsigned mismatch
+
+- TSqliteTable.FieldAsInteger(I: cardinal): int64; returns int64
+
+
+3 May 2005 Fixed bug where strupper called on column type before checking for nil
+
+2 May 2005 Add extra check for nil in TSqliteTable.Destroy, thanks to Tim Maddrell
+
+22 Apr 2005 Revise TSqliteTable.Destroy to fix memory leak with dtStr type (thanks to
+Jose Brito)
+
+21 Apr 2005 Quick revision to fix case sensitivity in detecting column type,
+and remove PRAGMA full_column_names = 1 which is deprecated. Warning: may break code. Fix your SQL code so that all column names in a result set are unique.
+
+21 Feb 2005 Sqlite DLL now 3.1.3 
+
+19 Feb 2005 Revised for Sqlite 3.1.2 
+
+21 Dec 2004 First public release
