Question : Loop over all user tables, return rowcount for each (Sybase ASE15)

I need to create a procedure which, when called, will return for every user table in a specific database, the tablename & row count.

I tried doing something with:
select distinct
    o.name,
    t.rowcnt
from systabstats t,
      sysobjects o
where t.id = o.id
and o.type = 'U'
order by o.name
go

But the result did not give me the correct # of rows. So I think I need something which will loop over all tables doing count(*) and returning tablename & rownumber. But this I cannot figure out. And, of course, I need it by this evening.

Answer : Loop over all user tables, return rowcount for each (Sybase ASE15)

The only way to do this is to open up a cursor on the sysobjects table and do a SELECT COUNT(*) FROM TableName as dynamic SQL.

Something like....

CREATE PROC sp_alltables_rowcount
AS
BEGIN
    SET NOCOUNT ON
    DECLARE     @ROWCOUNT_CMD       VARCHAR(255),
                @TABNAME            VARCHAR(32),
                @US_MSG             VARCHAR(128),
                @DB_MSG             VARCHAR(128)
   
    DECLARE TABLIST CURSOR FOR
    SELECT 'select ''' + name + ''', count(*) from ' + name AS ROWCOUNT_CMD,
           name AS TABNAME
      FROM sysobjects
     WHERE type = 'U'

    SET @DB_MSG = 'STARTING -- Rowcounts for database: '+
        db_name()+' at '+ convert(varchar,getdate())
    PRINT @DB_MSG

    OPEN TABLIST
    FETCH TABLIST INTO @ROWCOUNT_CMD, @TABNAME
    WHILE @@sqlstatus = 0
      BEGIN
        EXEC (@ROWCOUNT_CMD)
        FETCH TABLIST INTO @ROWCOUNT_CMD, @TABNAME
      END
    CLOSE TABLIST
    SET @DB_MSG = 'FINISHED -- Rowcounts for database: '+
        db_name()+' at '+ convert(varchar,getdate())
    PRINT @DB_MSG

    RETURN
END


Be sure to put this procedure in the SYBSYSTEMPROCS database.  You can then call it from any database and only have to maintain the code once.

BTW, I tested this on 12.5.1, not v15 so there is a very slight chance you may have to adjust the select statement in the cursor declaration.
