In SQL Server, an often used function is CAST(), which converts an expression of one data type to another. But if the cast doesn’t succeed, then it returns an error.
Enter TRY_CAST().
The TRY_CAST() function doesn’t return an error if the cast fails. Instead, it returns NULL.
There are some occasions however, where it will return an error.
In SQL Server, the TRY_CONVERT() function is very similar to the CONVERT() function, except that TRY_CONVERT() doesn’t return an error if the conversion fails (CONVERT() does).
Instead, the TRY_CONVERT() function returns NULL if the conversion doesn’t succeed.
There are some occasions however, where TRY_CONVERT() will return an error.
In SQL Server, the CONVERT() function converts an expression of one data type to another.
Here’s a quick overview of the function with examples.

In Oracle Database, the ROWIDTONCHAR() function converts a ROWID value to NVARCHAR2 data type
It’s similar to the ROWIDTOCHAR() function, except that ROWIDTOCHAR() converts a ROWID value to VARCHAR2 data type.
In Oracle Database, the ROWIDTOCHAR() function converts a ROWID value to VARCHAR2 data type.
In Oracle Database, the CHARTOROWID() function converts a string value to ROWID data type.
In Oracle Database, the TO_DATE() function converts its argument to a value of DATE data type.
In Oracle Database, the RAWTONHEX() function converts a raw value to hexadecimal.
It’s similar to the RAWTOHEX() function, except that its value is always returned in the national character set.
