Language used by the SQL Server binaries

SQL Server binaries come in various languages, such as 日本語 (Japanese), French, and English. It’s pretty easy to determine the language once SQL Server is *running*. A simple query does the trick:

Colorful speech bubbles with greetings in several languages, including Hello, Hola, Bonjour, Ciao, and Japanese and Chinese text.

However, if the instance is already down for some reason, and you want to install a cumulative update but aren’t sure what language you should install, you can check the system registry for the Locale ID, or lcid, of the installed language.

Checking the registry consists of the following steps:

  1. Run regedit.exe
  2. Navigate to the following key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL
  3. Find the name of the SQL Server instance you want to patch in the list, as shown here:
    Registry Editor showing the installed SQL Server instances in the right-hand pane

    The list of SQL Server instances installed is shown in the right-hand pane.

  4. Note the value listed in the Data column for the instance you’re interested in.
  5. Navigate to the following key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\<value from step 4 above>\MSSQLServer\CurrentVersion
    Windows Registry Editor showing SQL Server language settings, with the Language value circled and set to a hexadecimal LCID.

    Finding the SQL Server Language, or lcid, from the Registry.

  6. Lookup the value shown for Language in the chart below:
