Please follow these steps. Do not take the following steps if the previous steps are not performed to avoid damage to your database. generally, steps 4 and 6 are not recommended. Steps 4 are not secure and may damage the database or cause data loss.

1. Clear logs

Dump transaction database name WITH NO_LOG

2. truncate transaction logs

Backup log database name WITH NO_LOG

3. Compress database files (if not compressed, the database files will not be reduced

Enterprise Manager -- Right-click the database you want to compress -- all tasks -- contract database -- contract file

-- Select log file -- select to shrink to XXM in the contraction mode. Here, a minimum number of MB allowed to be shrunk is displayed. Enter this number directly and click OK.

-- Select data file -- select to shrink to XXM in the contraction mode. Here, a minimum number of MB allowed to be shrunk is displayed. Enter this number directly and click OK.

You can also use SQL statements to complete

-- Shrink Database

Dbcc shrinkdatabase (customer profile)

-- Contract the specified data file. 1 indicates the file number. You can use this statement to query:

Select * from sysfiles

Dbcc shrinkfile (1)

4. To minimize log files (for SQL 7.0, this step can only be performed in the query analyzer)

A. Separate the database:

Enterprise Manager -- server -- database -- Right-click -- detach Database

B. Delete LOG files in my computer
