Hi,
We have a DEC Alpha 4100 Server with OSF1 Digital Unix 4.0.
Can any one tell me, if there are any commands on this Unix which are equivalent to "top" and "sar" on HP-UX or Sun Solaris ?
I am particularly interested in knowing the CPU Load, what process is running on which CPU, etc.

Hi All,
I need to select only those records having a non zero record in the first column of a comma delimited file.
Suppose my input file is having data like:
"0","01/08/2005 07:11:15",1,1,"Created",,"01/08/2005"
"0","01/08/2005 07:12:40",1,1,"Created",,"01/08/2005"... (2 Replies)

Hi All,
I have working (Perl) code to combine 2 input files into a single output file using the join function that works to a point, but has the following limitations:
1. I am restrained to 2 input files only.
2. Only the "matched" fields are written out to the "matched" output file and... (1 Reply)

Hi All,
Thanks all for the continued support so far.

DBIx::Class::SQLMaker::LimitDialects(3) User Contributed Perl Documentation DBIx::Class::SQLMaker::LimitDialects(3)NAME
DBIx::Class::SQLMaker::LimitDialects - SQL::Abstract::Limit-like functionality for DBIx::Class::SQLMaker
DESCRIPTION
This module replicates a lot of the functionality originally found in SQL::Abstract::Limit. While simple limits would work as-is, the more
complex dialects that require e.g. subqueries could not be reliably implemented without taking full advantage of the metadata locked within
DBIx::Class::ResultSource classes. After reimplementation of close to 80% of the SQL::Abstract::Limit functionality it was deemed more
practical to simply make an independent DBIx::Class-specific limit-dialect provider.
SQL LIMIT DIALECTS
Note that the actual implementations listed below never use "*" literally. Instead proper re-aliasing of selectors and order criteria is
done, so that the limit dialect are safe to use on joined resultsets with clashing column names.
Currently the provided dialects are:
LimitOffset
SELECT ... LIMIT $limit OFFSET $offset
Supported by PostgreSQL and SQLite
LimitXY
SELECT ... LIMIT $offset $limit
Supported by MySQL and any SQL::Statement based DBD
RowNumberOver
SELECT * FROM (
SELECT *, ROW_NUMBER() OVER( ORDER BY ... ) AS RNO__ROW__INDEX FROM (
SELECT ...
)
) WHERE RNO__ROW__INDEX BETWEEN ($offset+1) AND ($limit+$offset)
ANSI standard Limit/Offset implementation. Supported by DB2 and MSSQL >= 2005.
SkipFirst
SELECT SKIP $offset FIRST $limit * FROM ...
Suported by Informix, almost like LimitOffset. According to SQL::Abstract::Limit "... SKIP $offset LIMIT $limit ..." is also supported.
FirstSkip
SELECT FIRST $limit SKIP $offset * FROM ...
Supported by Firebird/Interbase, reverse of SkipFirst. According to SQL::Abstract::Limit "... ROWS $limit TO $offset ..." is also
supported.
RowNum
Depending on the resultset attributes one of:
SELECT * FROM (
SELECT *, ROWNUM rownum__index FROM (
SELECT ...
) WHERE ROWNUM <= ($limit+$offset)
) WHERE rownum__index >= ($offset+1)
or
SELECT * FROM (
SELECT *, ROWNUM rownum__index FROM (
SELECT ...
)
) WHERE rownum__index BETWEEN ($offset+1) AND ($limit+$offset)
or
SELECT * FROM (
SELECT ...
) WHERE ROWNUM <= ($limit+1)
Supported by Oracle.
Top
SELECT * FROM
SELECT TOP $limit FROM (
SELECT TOP $limit FROM (
SELECT TOP ($limit+$offset) ...
) ORDER BY $reversed_original_order
) ORDER BY $original_order
Unreliable Top-based implementation, supported by MSSQL < 2005.
CAVEAT
Due to its implementation, this limit dialect returns incorrect results when $limit+$offset > total amount of rows in the resultset.
FetchFirst
SELECT * FROM
(
SELECT * FROM (
SELECT * FROM (
SELECT * FROM ...
) ORDER BY $reversed_original_order
FETCH FIRST $limit ROWS ONLY
) ORDER BY $original_order
FETCH FIRST $limit ROWS ONLY
)
Unreliable FetchFirst-based implementation, supported by IBM DB2 <= V5R3.
CAVEAT
Due to its implementation, this limit dialect returns incorrect results when $limit+$offset > total amount of rows in the resultset.
GenericSubQ
SELECT * FROM (
SELECT ...
)
WHERE (
SELECT COUNT(*) FROM $original_table cnt WHERE cnt.id < $original_table.id
) BETWEEN $offset AND ($offset+$rows-1)
This is the most evil limit "dialect" (more of a hack) for really stupid databases. It works by ordering the set by some unique column, and
calculating the amount of rows that have a less-er value (thus emulating a "RowNum"-like index). Of course this implies the set can only be
ordered by a single unique column.
Also note that this technique can be and often is excruciatingly slow. You may have much better luck using "software_limit" in
DBIx::Class::ResultSet instead.
Currently used by Sybase ASE, due to lack of any other option.
