The Only Database and File Handling Product You Will Ever Need

A better SQL/ODBC package
A better B-tree/ISAM package
In one integrated product with complete C++ source code!

CQL++ is a complete SQL and B-tree/ISAM database management system providing a single user or client/server solution for all machines and operating systems! The price of $495.00 (single user) or $995.00 (client/server) includes 100% C++ source code.

Major Features

ODBC Driver

Allows use of the wide variety of Windows GUI report generators and data manipulation tools such as Microsoft Access, Crystal Reports, etc.

C++ Library

Perform all SQL and ISAM operations from within your C++ programs. Use our C++ class library or the ODBC interface. ODBC functionality is implemented in the SQL server, so the ODBC interface (except for driver manager related functions and windows specific dialogs) is usable in non-windows environments.

Transaction Processing

Supports transaction commit and rollback, nested transactions, and logging and failure recovery.

Client/Server

Supports client/server processing over heterogeneous networks. Servers and clients can run in Windows NT, Windows 95, Windows 3.1 or Windows for Workgroups(client only), OS/2, Sun O/S, Sun Solaris, HP-UX, SCO UNIX, Linux, or any UNIX or other environment with a compatible C++ compiler.

ISAM Interface

Choose the SQL or the ISAM interface to maximize productivity and efficiency. ISAM access available for SQL base tables!

Unbelievable Royalties!

Distribute our server for only $25.00. No limit on number of clients and no per client charges. Single user version is royalty free!

One License Per Developer

For development, you need only purchase one license for each developer using CQL++, regardless of the number of development platforms.

Variable Length Support

Variable length data and keys are supported. Variable length character data and variable length binary data (BLOBs) are fully supported.

Supported Data Types

CHAR: Fixed length character string, maximum length 255 characters
VARCHAR: Variable length character string, maximum length 254 characters
LONGVARCHAR: Variable length character string, maximum length 64K characters
BINARY: Fixed length binary data, maximum length 255 bytes
VARBINARY: Variable length binary data, maximum length 254 bytes
LONGVARBINARY: Variable length binary data, maximum length limited by four byte length specification
BIT: Boolean value
TINYINT: 8 bit signed binary
SMALLINT: 16 bit signed binary
INTEGER: 32 bit signed binary
BIGINT: 64 bit signed binary
DECIMAL: Fixed point decimal number, 16 digits plus exponent.
REAL: 32 bit binary floating point
FLOAT: 64 bit binary floating point
DATE: Year, month, day
TIME: Hour, minute, second
TIMESTAMP: Year, month, day, hour, minute, second, fraction

Supported Standards

ANSI 1989 Level 2 SQL with integrity enhancement: All ANSI features supported including fully dynamic joins, DISTINCT, ORDER BY, and GROUP BY. All subqueries are supported including ALL, ANY, EXISTS, and interblock references. The referential integrity enhancement is supported. Those portions of ANSI SQL 1992 which are part of the ODBC extended language level are also supported (except stored procedures).
ODBC level 1 API and extended language level: Allows use of ODBC compliant tools as well as the ODBC class libraries provided with Visual C++ and other compilers. Complete ODBC language support includes character, numeric, and date/time functions, index related statements, and ALTER and DROP statements.

TCP/IP networking among homogeneous or heterogeneous machines

Data conversions are applied automatically when data is transferred between machines with different internal data representations. The ODBC driver and Windows clients support the winsock extensions to UNIX (Berkley) sockets.

Fully dynamic SQL

All statements, including CREATE, can be constructed at run time and executed dynamically. Both the prepare/execute and execute immediate sequences are supported.

Embedded SQL

The SQL preprocessor converts C++ files with embedded (EXEC SQL) SQL statements into C++ files.

Other Features

Strict serializability supported in multi-user version.
NULL values are fully supported at both the SQL and ISAM/B-tree levels.
ANSI privilege and security features are fully supported.
ANSI views are fully supported.
C++ source code makes extensive use of polymorphism allowing the user to readily extend the capabilities if necessary.
C++ class library calls are isolated in a single C++ source file and two C++ header files. To support a new environment, the user need only construct these three files for that environment. All the remaining source code is common to all hardware and software environments.
User configurable data buffer cache size speeds data access.
Case sensitive or case insensitive character keys.
Unlimited number of simultaneous SQL cursors.
Multi-user mode uses optimistic concurrency control with shared read locks, allowing a user to "see" his own modifications while other users see the unmodified data.
