+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 reformated to better look (official borland formationg
+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
