The query below lists all columns with numeric data types.
Query
select c.tabschema as schema_name,
c.tabname as table_name,
c.colno as column_id,
c.colname as column_name,
c.typename as data_type,
c.length as precision,
c.scale
from syscat.columns c
join syscat.tables t on c.tabschema = t.tabschema
and c.tabname = t.tabname
and t.type = 'T'
where c.typename in ('SMALLINT', 'INTEGER', 'BIGINT',
'DOUBLE', 'REAL', 'DECIMAL', 'DECFLOAT')
and c.tabschema not like 'SYS%'
order by schema_name,
table_name,
column_id;
