## Jira Link [CALCITE-7777](https://issues.apache.org/jira/browse/CALCITE-7777) ## Changes Proposed `MssqlSqlDialect` writes the `||` operator as `+`. SQL Server has no `||`, and `+` is the only rendering that keeps what `||` means: it propagates NULL, where the `CONCAT` function reads a NULL operand as the empty string and would turn a NULL result into a row. -- This is an automated message from the Apache Git Service.
