    The same query is running in production within 20 mins.

    Dev environment and production both has 3 GB RAM.

    Nos of processor is double in Dev environment.

    Dev environment also hosts SQL 2008 instance along with SQL 2000.

    Can suggest how can I fix the issue and what is the reason for the issue?

  • The script you've posted doesn't even parse.

    Msg 102, Level 15, State 1, Line 37

    Incorrect syntax near ','.

    Msg 134, Level 15, State 1, Line 76

    The variable name '@THIS_CALENDAR_YR_START_DT' has already been declared. Variable names must be unique within a query batch or stored procedure.

    Msg 102, Level 15, State 1, Line 106

    Incorrect syntax near ','.

    Msg 156, Level 15, State 1, Line 74

    Incorrect syntax near the keyword 'DECLARE'

    It uses a lot of log space because you're doing a lot of inserts and deletes. Unless you can figure a way so that you don't need to insert so much and delete so much, you won't be able to do much about the log space.

  • Thanks Gail for the quick response.

    But since the script is running fine in production why is creating such a mess in Development?

    Err... *rolls dice*

    More data

    Less memory

    Older stats

    Different recovery model

    etc

    etc
