-----------------------------------
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
