Sql Count In String

The number of characters in a string ' characters ' is 12, the length returned by the DATELENGTH function. As you can see, the string contains the spaces at the beginning and end. Also, you can apply the DATELENGTH on the table column containing the string value to count the number of characters.

For example, you may want to count all occurrences of a name in a text. This can be done, but it's not straight-forward because SQL Server doesn't have a specific function to do it.
