             Summary: Convert StructType to DDL string
                 Key: SPARK-24849
                 URL: https://issues.apache.org/jira/browse/SPARK-24849
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.3.1
            Reporter: Maxim Gekk


Need to add new methods which should convert a value of StructType to a schema in DDL format . It should be possible to use the former string in new table creation by just copy-pasting of new method results. The existing methods simpleString(), catalogString() and sql() put ':' between top level field name and its type, and wrap by the *struct* word

{code}
ds.schema.catalogString
struct<metaData:struct<eventId:string ...
{code}

Output of new method should be
{code}
metaData struct<eventId:string ...
{code}
