Julian Hyde commented on CALCITE-7456:
--------------------------------------
Can you make the summary look more like other summaries for cases that add
support for a function to a back-end dialect? Also remember function names
should be upper-case.
> 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
> Priority: Major
> Labels: pull-request-available
>
> 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
