Similar to CAST, TRY_CAST converts data types into other data types based on the specified parameters. If the conversion cannot be performed, TRY_CAST returns a NULL. To return an error message instead, use CAST.


TRY_CAST(<value> AS <type>)
Parameter Description
<value> The value to convert or an expression that results in a value to convert. Can be a column name, a function applied to a column or another function, or a literal value.
<type> The target data type (case-insensitive).


SELECT TRY_CAST('1' AS INT) as res, TRY_CAST('test' AS INT) as res1;

Returns: 1,null
