it helps some times Some things cannot be parameterized. That includes things like table and column names in DML, but includes most of DDL. It is not expecting, and cannot process, parameters in this scenario.
To check this; just run it in SSMS, declaring the variables ahead of time and giving them values. You will find the error message is the same. If it doesn't work in SSMS it is very unlikely to work from ADO.NET.

 Android database md5 change, why change same size?

around this issue As others have said, you can't rely on a hash of the database file to tell you whether it's been updated.
The only suggestion that I can think of is to add a table to your database that holds a timestamp of the last update to the database. Whatever updates the database on the server side would have to update that timestamp whenever it updates the database in any way.

 Change print output if database size reach near 2gb

it helps some times I have the following code that gives me a nice printout of the MySQL database size. And I just thought it would be nicer if the font could change if the database size reached near 2GB. I tried an if statement just above the last print, but then I just got a blank page. , You need something like this before your print statement: code :
$redAreaSize = "2048"
if ($dbSize['size'] > $redAreaSize) {
$message = "Database size is: <font color='red'><b><blink>{$dbSize['size']} {$dbSize['type']} </blink></b></font>"
} else {
$message = "Database size is: {$dbSize['size']} {$dbSize['type']}
}
if (
$dbSize['size'] > 2147483648 && $dbSize['type'] = 'B' ||
$dbSize['size'] > 2097152 && $dbSize['type'] = 'KB' ||
$dbSize['size'] > 2048 && $dbSize['type'] = 'MB' ||
$dbSize['size'] > 2 && $dbSize['type'] = 'GB'
)

 Why does moving postgres database to another server change database size?

hope this fix your issue It is to be expected that the restored database is smaller than the original.
A live database always has a certain amount of bloat (empty space) that is caused by updates and deletes. That space will be reused and is no problem normally.

 Is it possible to know the change in size of a database table per day over the past few days?

I wish did fix the issue. Oracle uses MMON background process to collect AWR statistics. Assuming it's not disabled (show parameter statistics_level should return TYPICAL or ALL since BASIC does not collect advisories or statistics), you can use the views dba_hist_seg_stat and dba_hist_snapshot like below. Replace the table name (your_table_name) and the dates (21-JAN-2019 / 28-JAN-2019) accordingly: code :
select obj.owner, obj.object_name,
to_char(sn.BEGIN_INTERVAL_TIME,'RRRR-MON-DD') start_day,
sum(a.SPACE_USED_DELTA) block_increase_bytes
from dba_hist_seg_stat a,
dba_hist_snapshot sn,
dba_objects obj
where sn.snap_id = a.snap_id
and obj.object_id = a.obj#
and object_name = 'your_table_name'
and end_interval_time between to_timestamp('21-JAN-2019','DD-MON-RRRR')
and to_timestamp('28-JAN-2019','DD-MON-RRRR')
group by obj.owner, obj.object_name,
to_char(sn.BEGIN_INTERVAL_TIME,'RRRR-MON-DD')
order by obj.owner, obj.object_name, start_day
/
