Remarks

This interface is obtained using the getResultSetMetadata method of a ResultSet object.

When a column in the select list of the ResultSet is a simple name or a compound name (table-name.column-name, correlation-name.column-name), then, the following information about that name can be extracted if it exists:

Alias name
Correlation name
Qualified version of the name
Table name
The name as written

For each column in the select list of the ResultSet, information about the domain of that column can be obtained:

Column Type: an integer from the Domain interface
Name of the domain
Size of the domain, for VARCHAR and BINARY domains
Scale and precision, for NUMERIC domains
