Hi all,

Depends of your TD version, maybe this can Help you.

     select
     databasename
     ,Tablename
     ,ColumnName
     ,CASE
          WHEN orden = 1 and nextTable = Tablename
             THEN 'COLLECT STATS COLUMN ( ' || trim(columnname) || ') '
          WHEN orden = 1 and nextTable <> Tablename
             THEN 'COLLECT STATS COLUMN ( ' || trim(columnname) || ') ON ' || trim(databasename) || '.' || trim(TableName) || ';'
          WHEN nextTable <> Tablename
             THEN ',COLUMN( ' || trim(ColumnName) || ' ) ON ' || trim(databasename) || '.' || trim(TableName) || ';'
             ELSE ',COLUMN( ' ||  trim(ColumnName) || ') '
     END as StatsCMD
     from
     (
     select
     databasename
     ,Tablename
     ,ColumnName
     ,ROW_NUMBER() over(partition by  databasename ,Tablename order by Databasename,
     Tablename, Columnname)  as orden
     ,MAX(Tablename) over(partition by  databasename order by Databasename, Tablename,
     Columnname rows between 1 following and 1 following)  as nextTable from dbc.statsv where
