Formatting Techniques to Enhance Readability of Query Output
Often the typical data in a column is much narrower than the maximum defined column size.
For example, the SESSION_ID column is defined as CHARACTER(108), and the DATASOURCE
column is defined as CHARACTER(128); actual values in those columns are usually much shorter.
Many query tools support automatic adjustment of column size for viewing results, but in some
cases, it is necessary to adjust the size of the columns returned from the query to improve
readability of the results.
Neoview SQL supports several string manipulation functions. Among these, the LEFT function
is useful for simple column size reduction. In addition to string functions, use of CAST is
sometimes helpful for modifying the appearance or size of numeric fields.
For example, the following query produces results that can be difficult to read:
select [first 10]
datasource,
client_id,
count(*) as query_count
from NEO.HP_METRICS.ODBC_QUERY_STATS_V1
where statement_status = 'START'
group by datasource, client_id
order by datasource, client_id;
