DESCRIPTIONtsql4mk is an experimental library and a console application for executing SQL statements against Metakit databases. It implements a subset of SQL92. tsql4mk uses Jean-Claude Wippler's Oomk and William Duquette's "snit" (Snit Is Not Incrtcl), version 0.97. The API is modelled after R. Hipps great SQLite http://www.sqlite.org. These manuals were partially copied and adjusted for tsql4mk from the language reference of SQLite . Thanks to D. Richard Hipp for this great piece of software.
LIMITSThe main limits of tsql4mk against SQLite are:
- much lower speed, although not measured yet (layer on a layer ...)
- only a small subset of the SQL language is implemented
- limited join capabilites
- no NULL is known
- no compilation required if you use the tclkit  runtime
- console, library and documentation are in one file -> easy installation and deployment
- yan can start with tsql4mk and later on switch to SQLite
Examples: | ---------------- | Usage: tsql4mk.kit ?-doc? ?-example? ?-run? ?-help? <filename> | -doc Show a bit of documentation | -example Display the example script | -run Run the example script | -html Show the html documentation
LIBRARYTo use tsql4mk, either unwrap tsql4mk.kit (using sdx) and source "tsql4mk.tcl", or if you use a new Tclkit with Metakit 2.4.9: simply source this starkit.
CONSOLE APPLICATIONtsql4mk.kit can be also as stand-alone console application in several ways:
| Usage: tsql4mk.kit <filename> <SQL STATEMENT>or via pipes:
| echo <SQL STATEMENT> | tsql4mk.kit <filename>Pipes can be used to execute several SQL statements at once from a file and pipe this into the tsql4mk.kit application.
| cat <sqlfile> | tsql4mk.kit <filename>This feature can be also used to convert a sqlite database into a metakit database:
| echo .dump | sqlite test.sqlite | tsql4mk.kit <filename>The reverse way metakit -> sqlite is currently not yet implemented.
