Hi Meenakshi,

In the package %Dictionary you can query all information about classes.

To list all properties before compilation (columns):

SELECT Class.Name AS ClassName, Prop.Name AS PropertyName,  Prop.Type 
FROM %Dictionary.ClassDefinition AS Class
INNER JOIN %Dictionary.PropertyDefinition AS Prop ON Prop.parent = Class.%ID
WHERE Class.Name = 'Sample.Person'
ClassName PropertyName Type
Sample.Person Age %Integer
Sample.Person DOB %Date
Sample.Person FavoriteColors %String
Sample.Person Home Address
Sample.Person Name %String
Sample.Person Office Address
Sample.Person SSN %String
Sample.Person Spouse Person

To list all properties after compilation (columns):

SELECT Class.Name AS ClassName, Prop.Name AS PropertyName, Prop.Type 
FROM %Dictionary.CompiledClass AS Class
INNER JOIN %Dictionary.CompiledProperty AS Prop ON Prop.parent = Class.%ID
WHERE Class.Name = 'Sample.Person'
ClassName PropertyName Type
Sample.Person %%OID %Library.CacheString
Sample.Person %Concurrency %Library.CacheString
Sample.Person Age %Library.Integer
Sample.Person DOB %Library.Date
Sample.Person FavoriteColors %Library.String
Sample.Person Home Sample.Address
Sample.Person Name %Library.String
Sample.Person Office Sample.Address
Sample.Person SSN %Library.String
Sample.Person Spouse Sample.Person

the contents of those %Dictionary tables is a little geared towards class/object models. If you want a more SQL-focused view on your tables, you can look at the INFORMATION_SCHEMA package, which adheres to mainstream JDBC/ODBC dictionary structure and is used by mainstream SQL and BI tools like DBeaver, VSCode-SQLTools, Tableau, PowerBI, etc

Note you'll need to tick the "System" checkbox when browsing this schema in the System Management Portal.

Thanks Benjamin for the explanation,

Bellow the query in the INFORMATION_SCHEMA tables:

SELECT Tables.TABLE_SCHEMA, Tables.TABLE_NAME, Columns.COLUMN_NAME, Columns.DATA_TYPE
FROM INFORMATION_SCHEMA.TABLES AS Tables
INNER JOIN INFORMATION_SCHEMA.COLUMNS AS Columns 
   ON (Columns.TABLE_SCHEMA = Tables.TABLE_SCHEMA) AND (Columns.TABLE_NAME = Tables.TABLE_NAME)
WHERE (Tables.TABLE_SCHEMA = 'Sample') AND (Tables.TABLE_NAME = 'Person')
TABLE_SCHEMA TABLE_NAME COLUMN_NAME DATA_TYPE
Sample Person ID integer
Sample Person Age integer
Sample Person DOB date
Sample Person FavoriteColors varchar
Sample Person Name varchar
Sample Person SSN varchar
Sample Person Spouse integer
Sample Person Home_City varchar
Sample Person Home_State varchar
Sample Person Home_Street varchar
Sample Person Home_Zip varchar
Sample Person Office_City varchar
Sample Person Office_State varchar
Sample Person Office_Street varchar
Sample Person Office_Zip varchar
