A. A. Most of the information in the SQL log (syslogs) is not accessible via standard SQL commands. There are ways of accessing this information from SQL 6.5 and below. Ostensibly because syslogs is held (more or less) as a SQL table. With SQL 7 this is no longer the case, and there is no api/fil format published for it. Therefore log viewing tools for 7.0 are unlikely to appear any time soon.
SQL 6.5 and below options are :-
1. You can get transaction id and operation type only (no data) through a select * from syslogs. Or use the following code (courtesy of Tibor Karaszi) to make it a bit more readable.

2. dbcc log command. Not well documented, but some details below for SQL 6.5.Note that as with most undocumented dbcc commands you need to do a dbcc traceon(3604) first to see the output.
3. 3rd party. Logview from www.dbsg.com.
4. 3rd party. Image Analyzer from www.platinum.com. This product also allows extracting data and SQL statements from the log.
dbcc log \[ (@dbid, @objid, @pagenum, @rownum, @records, @type \[, @printopt\]) \]
dbcc log (5, 0, 0, 0, -1, 0, 1) // Show the last begin transaction record in the log
@dbid Database ID
@objid Object ID
A negative value indicates that @pagenum & @rownum represent a row in the log to use as a starting point in the scan of the log.
A value of zero indicates that log records for changes to @pagenum will be included in the commands output.
A positive value followed by a non-zero value for @pagenum indicates that @pagenum and @rownum represent a transaction ID. Log records for that transaction will be included in the output.
A positive value followed by zero values for @pagenum and @rownum indicates an object ID. Log records for changes to that object will be included in the output.
@pagenum page number
@rownum row number in the log
Together with @pagenum, this is either a starting point in a scan of the log or a transaction id.
@records number of records to examine. If positive, the first
