> 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
