Summary
Bumps the pinned
mssql-py-corenative dependency from0.1.3to0.1.4ineng/versions/mssql-py-core.version.Version
0.1.4ships the fix for #547, wherecursor.bulkcopy()failed when any row contained an empty string ("") destined for anNVARCHAR(MAX)(orVARCHAR(MAX)) column, surfacing as a misleading SQL error 40197 / 4804. With this bump, empty-string values are accepted as valid input by bulk copy, matching the behavior forNVARCHAR(n)columns.No source or test changes are required in this repository — the fix lives in the
mssql_py_corewheel and is picked up automatically byeng/scripts/install-mssql-py-core.{ps1,sh}, which read the pinned version fromeng/versions/mssql-py-core.version.
