123SQL是一个SQL数据库工具，可以浏览错误产生时正在执行的SQL语句。它是为PDA用户设计的，可以让用户浏览SQL数据库。
123SQL is a small portable sqlsyntax browsing relational database.

Data import/insert into the database is TAB delimited spreadsheet data.

123SQL was designed to enable PDA users browse their data in sql manner.

This is an undergoing project aimed to construct a small portable SQL database engine for PDA's, and this is a functional browsing engine that contains data and sample browsing statements.

Data may be imported together with table/column creation. Typically the source data may be spredsheet column TAB delimited export data. Database/table/column creation may be viewed in the included code following the -c switch.

Table names and column names and field byte sizes should be specified, but column/field lengths my also vary in size row by row. The engine performs SQL keyword/syntax checking using the syntax/keywords list files included. Object names check and object attributes read is performed in the system database files named 123SQL_db_1.mar and 123SQL_db_2.mar.

Database structure allows multiple object browsing. The sorting/searching routines require low machine resources thus meeting most modern PDA specifications and their sources were also published under different names.
