Research direction
The issue reports that the LENGTH function is not recognized in SQL Server. Investigate the function mapping in APIJSON's ORM layer, likely in files handling SQL dialect differences. The solution could involve adding LEN as an alias for LENGTH in the SQL Server dialect. Refer to the issue comments and existing PRs for additional context.
