[jira] [Commented] (IGNITE-2223) CPP: ODBC queries sometimes return wrong types for columns in metadata.

    [ https://issues.apache.org/jira/browse/IGNITE-2223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15094660#comment-15094660 ] 

Igor Sapego commented on IGNITE-2223:
-------------------------------------

After a closer look I found out that the issue is not in wrong type, returned by the metadata queries. The real issue is that on the C++ side we does not support Decimal type yet so we don't know how to read it which causes an error during row fetch.

> Some SQL queries return wrong types in metadata. For example, if query result set has column of type "Decimal" it will be transferred as "Long" instead. As a result, value can not be read in the application data buffer during row fetch.
