getTypeName

public String getTypeName()
                   throws SQLException

Description copied from interface: StructMetaData

Returns the name of the struct type. The user can set the struct type name in SQL explicitly by using struct <name> (...) clause.
For example: SELECT struct Foo (a, b) from T will give the struct (a, b) the name foo.

Specified by:

getTypeName in interface StructMetaData

Returns:

The name of the struct type.

Throws:

SQLException

getArrayMetaData

public ArrayMetaData getArrayMetaData(int oneBasedColumn)
                               throws SQLException

Description copied from interface: StructMetaData

Get the Metadata for an array type. If the column is not an array type, this will throw an error.
