[jira] [Created] (CALCITE-7456) Improve the conversion of try_cast function with mssql

terran2010 created CALCITE-7456:
-----------------------------------

             Summary: Improve the conversion of try_cast function with mssql
                 Key: CALCITE-7456
                 URL: https://issues.apache.org/jira/browse/CALCITE-7456
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.41.0
            Reporter: terran2010


When we execute the following SQL:
{code:java}
select TRY_CAST(gross_weight as bigint) as gross_weight_value from product {code}
Cacltie will output:
{code:java}
SELECT SAFE_CAST([gross_weight] AS BIGINT) AS [GROSS_WEIGHT_VALUE] FROM [foodmart].[product] {code}
We can find the following document, msSQL does not have the SAFE-CAST function, we can consider optimizing it
