  • RE: SQL S2000 - Unable to Connect to SQL Server

    Both failed to start.

    With what error? and what's in the event log (application event log) for that time?

    Let me guess, no database backup?

  • RE: Weird pattern of behaviour

    Pleasure. I've had the problem a few times.

    What happens is that both sides of the expression must be of the same type. If the column is varchar and the parameter...

  • RE: its urgent [purge data from ldf files to reduce ldf file size]

    You want to clear out inactive transactions from the log?

    If the database is in simple recovery mode, the log will truncate itself automatically after a checkpoint. If you're using full...

  • RE: fetch data from ldf files

    the ldf is the transaction log. It's the record of what modifications have been made and isn't intended to be read.

    What info are you trying to get? Why do you...

  • RE: last record

    Which will work if you have an identity column called recordID

  • RE: Weird pattern of behaviour

    The SELECT returns at most a single row for every entry in the IN clause.

    Yes, but how many enteries do you typically have in the IN clause? There comes a...

  • RE: IF DATABASE EXISTS ???

    That's still going to give an error, from the parsing of the USE statement 

    Could not locate entry in sysdatabases for database 'MyDB'. No entry found with that name....

  • RE: Does JOIN order effect efficiency?

    The join order does not affect performance. The query optimiser will reorder the join to find the cheapest plan possible. I think it's been this way since SQL 7

    SELECT t0.col1,

    t0.col2,

    t0.col3,

    t0.col4,

    t0.col6,

    t0.col7,

    t0.col8

    FROM dbo.table1 t0

    WHERE (t0.col8 IN (?))

    That select will table scan if the number of records returned exceeds more than about 1% of the table. I can't tell whether the in...

  • RE: Truncate Log didn''''t work for all databases

    Please don't ever run ShrinkDatabase on a production database without a very, very good reason. All you're going to achieve is to fragment all your indexes badly and force the...
