For now, instead of removing this entirely, let’s add an MSSQL-specific check; otherwise, we’d need to test all other drivers.

It will not break anything. As there is no change in the code flow. I am doing the same thing now but in a different place

IMO, for now we should implement for mssql only

do we need this check as cursorField is never going to be empty

No need to check cursorField

Description
The shared JDBC helper no longer converts scanned cursor values (e.g. []byte → string). It returns raw values; each source normalizes before writing state.
Postgres, MySQL, DB2: normalize by turning []byte cursors into strings.
MSSQL: normalize using column type (existing normalizeMSSQLValueForState) so incremental state matches what the backfill path uses.
Why
Central conversion was wrong or insufficient for some drivers/types; normalization must be driver- and type-aware (especially MSSQL).
