get the version information of SQL server
Microsoft support has a web page for this.
In short,
1. run 'select @@version'.
if the version number string is started with "8.", "9." or later, then run
"SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')"
The following table lists the Sqlservr.exe version number.
The following table lists the Sqlservr.exe version number.
In short,
1. run 'select @@version'.
| Version Number | Service Pack |
|---|---|
| 6.50.479 | SQL Server 6.5 Service Pack 5a (SP5a) Update |
| 6.50.416 | SQL Server 6.5 Service Pack 5a (SP5a) |
| 6.50.415 | SQL Server 6.5 Service Pack 5 (SP5) |
| 6.50.281 | SQL Server 6.5 Service Pack 4 (SP4) |
| 6.50.258 | SQL Server 6.5 Service Pack 3 (SP3) |
| 6.50.240 | SQL Server 6.5 Service Pack 2 (SP2) |
| 6.50.213 | SQL Server 6.5 Service Pack 1 (SP1) |
| 6.50.201 | SQL Server 6.5 RTM |
| Version Number | Service Pack |
|---|---|
| 7.00.1063 | SQL Server 7.0 Service Pack 4 (SP4) |
| 7.00.961 | SQL Server 7.0 Service Pack 3 (SP3) |
| 7.00.842 | SQL Server 7.0 Service Pack 2 (SP2) |
| 7.00.699 | SQL Server 7.0 Service Pack 1 (SP1) |
| 7.00.623 | SQL Server 7.0 RTM (Release To Manufacturing) |
if the version number string is started with "8.", "9." or later, then run
"SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')"
The following results are returned:
- The product version (for example, 8.00.534)
- The product level (for example, "RTM" or "SP2")
- The edition (for example, "Standard Edition"). For example, the results resemble the following:
8.00.534 SP2 Standard Edition
| Release | Sqlservr.exe |
|---|---|
| RTM | 2000.80.194.0 |
| SQL Server 2000 SP1 | 2000.80.384.0 |

full disk encryption and filesystem encryption
eCryptfs seems support TPM. in its README,
...Future versions of eCryptfs will allow hardware token devices, such as a TPM chip, to protect your secret keys....
But there is a file named ecryptfs-utils-83/src/utils/ecryptfs_generate_tpm_key.c.
It is necessary to look into further.
eCryptfs: An Enterprise-class Cryptographic Filesystem for Linux introduce the eCryptfs in detail.
MetFS (FUSE) doesn't support TPM by observing its source.
EncFS (FUSE), no clue now.
CryptoFS (FUSE) doesn't support TPM by observing its source.
TrueCrypt (On-The-Fly Disk encryption) doesn't support TPM explicitly.
Full disk Encryption in wikipedia is a good start for information of this kind.
Fedora Core 4 support disk encryption. (dm-crypt ?)
Fedora's Release note: FeatureEncryptedFilesystems outline something on this topic.
Comparison of disk encryption software - BestCrypt, Bloombase Keyparc, Check Point Full Disk Encryption, cryptoloop, dm-crypt, eCryptfs, FREE CompuSec, loop-AES, Scramdisk, SecureDoc, TrueCrypt
