utility with source code, comprehensive help and demos.SQLMemTable provides the following services: - SQL support - Master / detail relationship - Creating, renaming, emptying, deleting and restructuring tables - Creating, editing, deleting, navigating and searching for records - Creating and deleting multiple indexes - Calculated and lookup fields - Filtering support - Using
BLOB
fields with data compression ability - Importing from and exporting to any dataset in fast and easy way - Internationalization/Localization and Unicode supportSQLMemTable does not require BDE or any external drivers and has small footprint. Its search performance is excellent and data access speed is extremely fast.Specification-------------Data types: ftAutoInc, ftInteger, ftSmallInt, ftFloat, ftDateTime, ftDate, ftTime, ft

BLOB
compression: ZLib, BZip, PPM Search operators: <,>,=,<>,<=,>=, like, not like, is null, is not null, and, or, not, (). Features and Benefits---------------------Compactness. - Short compiled code with approximate size 300 Kb, no external drivers (such as BDE) required. - Small memory consumption by SQLMemTable
database
engine. - Fast
BLOB
data compression. Your large data fields will need less memory. SQLMemTable can compress data on the fly. The compression routines used in the SQLMemTable are much faster than most of popular archivers like PKZip, WinRar, Arj. High performance. - Fast search by B-tree indexes. At the moment SQLMemTable is one of the fastest existing in-memory tables for Delphi and C++ Builder. - High-speed memory operations performance is achieved by means of using specially optimized memory manager and tuned algorithms. - Quick operations with strings. SQLMemTable compares strings up to 3 times faster than standard Delphi string routines. High performance is achieved by using a special library written in Assembler and an advanced sorting algorithm. - Advanced SQL optimizer often makes query execution several times faster by choosing the best execution plans. Functionality. - A subset of SQL‘92 including DDL operators is supported by TSQLMemQuery component. With SQLMemTable you can create SQL scripts for creating tables, inserting, editing and deleting records, retrieving data by SELECT command. - Advanced search engine. SQLMemTable supports ‘LIKE‘ operator with wildcards ‘%‘ and ‘_‘, as well as ‘IS NULL‘ and ‘IS NOT NULL‘ in filters and queries. - Full multiple index support, i.e. numerous fields in a table may comprise an index. SQLMemTable provides descending and ascending indexes, case-sensitive and insensitive indexes for string fields. - Shareable in-memory tables. SQLMemTable supports simultaneous access to a table by multiple TSQLMemTable components within a single application. - Default values support. - Record-level constraints, i.e. constraints that must be met when editing the data. Compatibility. - SQLMemTable supports most of TTable field data types, including
BLOB
fields, moreover it allows to create string and wide string fields of any fixed length. - SQLMemTable is fully compatible with standard DB-aware visual controls such as QuickReport, DBGrid, DBNavigator, DBImage, DBMemo, DBRichEdit, as well as with third party vendor‘s products supporting TDataset descendant components - FastReport, DBFlyTreeView and others. - Calculated and lookup fields can be used in the same way as TTable. - Most of TTable functions are supported including Key and Range methods. Convenience. - Table restructuring is being performed in the easiest way keeping all the existing data. - Data importing from and exporting to any dataset is supported. SQLMemTable provides you with the simplest way to import and export tables using ImportTable and ExportTable methods. - Internationalization / localization support. All text search and sorting functions use current system locale, so localizing your program with SQLMemTable is a very simple task. - Unicode support. All the text operations work with multi-byte encoding using ftWideString. - Comprehensive help. SQLMemTable comes with full documentation presented in SQLMemTable Developer‘s Guide and SQLMemTable Reference. Installation------------1) Make sure that all copies of Delphi (or C++ Builder) are currently closed and not running on the target system. Also, if you are replacing an existing version of SQLMemTable, please remove all files and the package of the prior version before running the new setup program.2) Unpack zip archive containing SQLMemTable into any directory. 3) Run the INSTALL.EXE from this directory.4) Follow on-screen instructions of step-by-step setup wizard to install SQLMemTable.5) If after the installation SQLMemTable components don‘t appear in Components Palette of the IDE, please follow the next instructions: * From the IDE, select ‘Component | Install Packages...‘. * Click the ‘Add‘ button. * In the ..SQLMemTableLibDelphi# (or ..SQLMemTableLibC++ Builder#) directory, select the dclSQLMemTableD#.BPL (or dclSQLMemTableB#.BPL) file. * Click the ‘OK‘ button to close the dialog. * Finally, select ‘Tools | Environment Options‘ from the main menu. From this dialog, select the ‘Library‘ tab and insure that the ..SQLMemTableLibDelphi# (or ..SQLMemTableLibC++ Builder#) directory is included in the ‘Library Path‘ line.Purchasing / Registration-------------------------Visit our site http://www.aidaim.com to purchase or register the product.Copyright and license---------------------See "license.txt" file.Warranty and guarantee----------------------See "license.txt" file.Technical support-----------------Before you contact us, please do the following: - Make sure you have performed all the required steps correctly. - Look at the Help files and Demos: it may already contain an answer to your question.

AidAim Software had tested all these products released by our partner companies for complete compatibility with SQLMemTable. In its turn, all the partner companies have carried out similar testing of the compatibilityof SQLMemTable with their own products. All the companies whose products present here are technology partners of AidAim Software. It means that both partner companies guarantee the correct joint work of the products. In case of encountering bugs in the time of joint work and owing to it, the partners incur the obligation to resolve such problems for their clients for FREE. FastReport Software -------------------Advanced report generators for Delphi and Kylix.Web Site: http://www.fast-report.comFastReport VCL--------------FastReport VCL is reporting tool component for Borland Delphi 2-6 and Borland C++Builder 3-5. It consists of report engine, designer and preview. Some FastReport possibilities are really unique. The generator allows you to create tables, queries and
database
s in run-time. Built-in dialog designer allows you creation of dialog forms (they can be used for asking some parameters before printing a report). You also able to use built-in Pascal-like interpreter to do rather complex data processing. In spite of power of FastReport, its code is quite small. Probably FastReport is leader in correlation of functionality/size. The FastReport kernel (without designer) adds to your program the small footprint (less than QR3), but its functionality is like in ReportBuilder‘s one.FastReport CLX edition----------------------FastReport CLX edition is powerfull of FastReport for Borland Delphi 6 and Borland Kylix 1-2 for Linux. It use new CLX-library. Do you want to create reports for Linux as well as for Windows? Use FastReport CLX edition!FastReport VCL 2.3 lite-----------------------FreeWare version of FastReport. Imca Systems DevTeam --------------------Imca Systems DevTeam - Flexible and powerful Delphi/C++ Builder/ActiveX trees, grids and editors.Web Site: http://www.9rays.netDBFlyTreeView Suite-------------------Add grid and treeview functionality with a single component. DBFlyTreeView is a fully customizable, data-bound grid and tree view component that allows you to add huge arrays of nodes.
OLE
drag-and-drop is supported and the component is customizable at both design-time and runtime. DBFlyTreeView supports custom colors, fonts, and alignment for each cell, and you can even create scrollable background wallpapers without creating huge bitmaps.Included: RapidTree, FlyTreeView, PropertiesTree, DBFlyTreeView controls.DBFlyTreeViewPro Suite----------------------Enable your Delphi and C++Builder applications to display and browse hierarchical, table, and list data. DBFlyTreeViewPro Suite is a set of VCL components that are a direct descendent from FlyTreeViewPro. It supports more than 40 types of in place editors plus your custom format. It is data-aware and allows you to draw any array of cells directly to a printer, Metafile, or Bitmap canvas.Included: RapidTree, IsPlugeditor, FlyTreeViewPro, PropertiesTreePro, DBFlyTreeViewPro controls.
