The CHARINDEX function in SQL is used to return the position of the first occurrence of a specified string within another string. Its syntax is as follows:

Locates the position of the search_string within the target_string, starting from the specified start_position.

Among them,

  1. search_string: the string to be searched.
  2. String to be searched within.
  3. start_position (optional): the starting position for the search, default is 1.

The CHARINDEX function returns an integer value that represents the position of a specified string within the target string. If the specified string is not found, it returns 0.
