Datalayer Problems

This topic introduces the different types of datalayer problems you could run into when developing Logi Studio, as well as possible solutions.

Problems Displaying Query Results:

• To display query results, use the token @Data.column_name~ to access the data in each column returned. Token names are case-sensitive, so ensure that the case of the token matches the column name returned in the datalayer.
• Data returned into a datalayer can be examined using links on the Debugger Trace Report; turn on debugging links to view this page.
  

Joining Datalayers:

• Relationships between datalayers in a report can be created using a Join element, see Join Datalayers. This can be used to produce SQL-like joins of data from SQL and non-SQL datasources.
