  I have a column " CID" which has values like this:

  CID :

  150569-Missing

  120567-HEALTH

  R60318-Missing

  5403-HEALTH

  40475-HEALTH

  003182173-health

  need to get only the numeric value ( that is digits before '-')

  example '150569-Missing' need only 150569

  cannot use function as I need this column on join.

  Can anyone help me with this??

  Do you want something like:

  SELECT LEFT(CID, CHARINDEX('-', CID)-1) AS BeforeDash

  Now that won't be sargable, which may have been the intent of your original question.

  also watch for those fields that are missing the dash:

  SELECT

  CASE

  WHEN CHARINDEX('-', CID) >= 0

  THEN LEFT(CID, CHARINDEX('-', CID) - 1)

  ELSE CID

  END AS BeforeDash

  Just to add to the solutions, if at all possible split that into two columns. It appears you have two pieces of information in a single column. This type of thing will cause you nothing but pain in the long run. A column should hold a single piece of information.
