SQL Server error message 195, with a severity level of 15, is a common error that occurs when a T-SQL statement references a function or command that the SQL Server engine does not recognize as a built-in function or as a user-defined function in the current context. This error is indicative of a syntax issue or a reference to a function that does not exist in the database you are working with. Is not a recognized built-in function name means that the function name is misspelled or does not exist.
Common causes of this error include:
Typographical Errors: A common reason for this error is typographical mistakes in the SQL statement. Check the spelling of the function or command you are trying to use.
Incorrect Context: Some functions or commands are only valid in specific contexts. For example, you cannot use certain string functions in a numeric context, and vice versa. Make sure you are using the function in an appropriate context.
Function Does Not Exist: Ensure that the function you are trying to use actually exists. It may not be a built-in function or a user-defined function in the current database.
Quotation Marks: If you are using a string function, make sure you have enclosed the string in single or double quotation marks, depending on your SQL Server's configuration.
Case Sensitivity: SQL Server is usually case-insensitive, but depending on the collation settings, it can be case-sensitive. Double-check the case of the function or command name to make sure it matches the database's collation settings.
