Gladius DB 0.7.0

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.<br /><br />You will not need any specific extension to have it work, and it is bundled with an adoDB lite driver.<br /><br />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.<br /><br />SQL Conformance<br /><br />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.<br /><br />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.<br /><br />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.<br /><br />Limitations:<br /><br />??? performance slowdown with a huge number of records<br />??? no storage gain for binary fields (for example, numbers)<br />??? non-validating SQL parser (an SQL query that works with Gladius may not be syntactically correct)<br />??? all strings are considered binary and should always be Unicode safe<br />??? no specific collation or character set support<br />??? cannot SELECT calculated or immediate values<br />??? CHAR VARYING, DOUBLE PRECISION and INTERVAL data types (specified in the SQL92 standard) are not recognized<br />??? no specific date/time fu
