As the doc mentioned:
https://learn.microsoft.com/en-us/sql/relational-databases/security/encryption/always-encrypted-enclaves-configure-encryption-tsql?view=sql-server-ver15
Note
Currently, the Invoke-Sqlcmd cmdlet in the SqlServer PowerShell module and sqlcmd, do not support using ALTER TABLE/ALTER COLUMN for in-place cryptographic operations.
My Question is: How to Decrypt Column Encrypted by Always Encrypted Using sqlcmd without in-place way?
Any comments are appreciated. thank you!

Is there an SQL command for MySQL in order to decrypt values which were encrypted by hibernate using the algorithm PBEWithMD5AndTripleDES?
Ouch, no, sorry but there is no such thing in SQL as a native function.
you might like to take a look on this site to create your Frankenstein functions to resolve that

I hope it helps!
I will take example of my case . I am using PostgreSql .I have gone through postgresql crypt() function documentation .
This function is provided as extension for postgresql .
If i migrate my data to another database by different vendor , Will the passwords still be evaluated properly or not ?.
If i try to compare the the hash generated in postgresql with hashing utilites provided by mysql/mongodb using same source string will it evaluate to be equal or not
According to docs, crypt()
Calculates a crypt(3)-style hash of password. When storing a new
password, you need to use gen_salt() to generate a new salt value. To
check a password, pass the stored hash value as salt, and test whether
the result matches the stored value.
It means if you migrate your data to another database (if stored hash value is part of your data of course), the result of comparison will not depend on the system.
Can you move up the encryption/decryption to the application level? In that case, you can migrate data as encrypted and other database vendor don't need to worry would consider them as normal data?
Another option is to encrypt disk level instead of applying encryption at a database level.
After going through lot of posts it came to me that encrypting at application layer is better . like for example to encrypt passwords in java, we can use jBcrypt library .
I need to encrypt some specific columns in mysql database. I researched and found few ways like AES_ENCRYPT functions, but these solutions requires sending the key value in the query.
I am looking for a solution where password can be stored in database some location and mysql can automatically use that value to encyrpt or decrypt that particular column?
Thank you.
I'm working with a web application and I want to get the hash value of the text which is saved in a MySQL database table,I'm new to this field and I'm using Spring-MVC for the web application,can any one please help me?
By hash, are you talking about any specific hashing function? A common one that you can use is md5, which mysql supports:
select md5(some_column) from some_table;
Here's a link to the reference: Mysql Reference/Encryption Functions
I am trying to encrypt and decrypt the data using SHA 5 in mysql. I am able to encrypt the data but unable to decrypt it. How can I achieve the decrption of SHA5 encrypted data in mysql.
What do you exactly want to do ? As Michael says, you will not be able to reverse a hash. We use hash when we want hide the real information and never decrypt it. If you want to decrypt it, then use an inversible function.
Hash algorithms (SHA = secure hash algorithm) are one way. You can use then to verify information such as a password by checking that the password entered, when SHA'd, equals the encrypted version on record. You can't decrypt with it though.
