-{
- 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
