Lianja v4.0 APaaS Developer will not run on XP. Lianja App Builder will but some of the important features for developers will not be available for Lianja App Builder.
This is due to the fact that some of the technologies we will be incorporating into Lianja v4.0 APaaS Developer will not install or run on XP.
Windows 7 and upwards will be supported.


the maximum number of columns in a table is 256, according to http://www.lianja.com/doc/index.php/System_Capacities.

When we build the distributions of Lianja we code sign the executables and the DLLs. This is required so that they can be installed on Windows.
On January 1, 2016, Microsoft plans to discontinue support for code signing certificates with a SHA-1 algorithm. To ensure compliance, EV code signing certificates are available with only SHA-256.
Note: Code signed with a SHA-256 certificate may not work with older operating systems.
The following article provide details concerning what operating systems support SHA-256.

It’s getting confused as the object and the class have the same name.
Try changing the object name to see if that resolves the issue. The reason for this is that Lianja supports static methods and properties so the parser is getting confused.


a) maximum character variable size
64k.
The Lianja database engine is common across Lianja, Lianja SQL Server and Lianja Cloud Server so this value was chosen to minimize resource usage on heavily loaded systems. Bear in mind also that Apps are portable between 64 bit and 32 bit systems (and soon mobile).

b) maximum VFP command length
16k

c) maximum SQL Select statement length
16k

d) maximum index key length
192 characters (indexes have a unique value postfixed so that the B+ tree indexes are properly balanced)
