Select Column Names for OpenEdge-SQL

Question

I'm using DBeaver to connect to Open-Edge 11 database which supports SQL functions. The functions used HERE don't work. Here is a single example and the result:

Function:

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'TxMSAGrading'

Error:

SQL Error [42S02]: [DataDirect][OpenEdge JDBC Driver][OpenEdge] Table/view/synonynm "INFORMATION_SCHEMA.COLUMNS" cannot be found. (15814)

How can I get column names?

Answer 1

Column information is stored in Progress system tables called "syscolumns". Here is an example to retrieve column information of the "Customer" table:

select col from sysprogress.syscolumns where tbl = 'customer';
