Apply indexing and fire reindexing query once or twice a day based on new record insertion-update or delete

Hello,

Use SHRINKFILE to shrink the data file size. According to the documentation on MSDN[^] SHRINKFILE

Shrinks the size of the specified data or log file for the current database, or empties a file by moving the data from the specified file to other files in the same filegroup, allowing the file to be removed from the database. You can shrink a file to a size that is less than the size specified when it was created. This resets the minimum file size to the new value

The syntax is

DBCC SHRINKFILE 
(
    { file_name | file_id } 
    { [ , EMPTYFILE ] 
    | [ [ , target_size ] [ , { NOTRUNCATE | TRUNCATEONLY } ] ]
    }
)
[ WITH NO_INFOMSGS ]

Basically, you can't - deleting records does not reduce the size of the file, the space is just released for future records.
You need to use the management studio to Shrink it: MSDN[^]
