Properties
ConcatRequiresExplicitStringCast
When true (default), ConvertConcat(SqlConcatExpression) wraps every non-string
operand in an explicit CAST(... AS VARCHAR(N)) before adding it to the concat chain.
Required for providers whose concat operator is + (SQL Server pre-2025, SqlCe,
Sybase ASE, Access) — SQL-standard data-type precedence would otherwise try to coerce
string operands to the non-string side's type. Providers whose final concat operator is
|| (PostgreSQL / Oracle / SQLite / SAP HANA / DuckDB / Firebird / DB2 / Informix /
SQL Server 2025+) or CONCAT(...) function (MySQL / ClickHouse) auto-coerce
non-string operands and override this to false for cleaner SQL.
