linux default iconGladius DB Publisher's description

Gladius DB is a fast and efficient PHP flatfile database engine written in pure PHP.

Gladius DB is a fast and efficient PHP flatfile database engine written in pure PHP; its SQL syntax is compatible with a subset of intermediate SQL92.

You will not need any specific extension to have it work, and it is bundled with an adoDB lite driver.

This project is licensed under the GNU General Public License, be sure to have read and understood it before using Gladius in your own software.

SQL Conformance

The formal name of the SQL standard is ISO/IEC 9075 "Database Language SQL". The version this document refers to is ISO/IEC 9075:2003, or simply SQL:2003. The versions prior to that were SQL:1999 and SQL-92. Each version supersedes the previous one, so claims of conformance to earlier versions have no official standing.

Starting with SQL:1999, the SQL standard defines a large set of individual features rather than the three levels (Entry, Intermediate and Full) declared in SQL-92. A large subset of these features represents the "Core" (mandatory) features, SQL implementation must supply in order to claim conformance. The rest of the features are purely optional.

In the following sections, we provide a list of all SQL:2003 features with an indication of whether it is supported by Gladius DB; every feature consists of an unique identifier and a name. Feature identifiers containing a hyphen are subfeatures. If a particular subfeature is not supported, the main feature is listed as partly supported. Comments are provided where necessary.


??? performance slowdown with a huge number of records
??? no storage gain for binary fields (for example, numbers)
??? non-validating SQL parser (an SQL query that works with Gladius may not be syntactically correct)
??? all strings are considered binary and should always be Unicode safe
??? no specific collation or character set support
??? cannot SELECT calculated or immediate values
??? CHAR VARYING, DOUBLE PRECISION and INTERVAL data types (specified in the SQL92 standard) are not recognized
??? no specific date/time fu
