mssql-django 1.7.4 Release Notes (July 2026)

mssql-django 1.7.4 is a patch release that fixes two bugs in raw and annotated GROUP BY query handling.

---

Bug Fixes

FIX: Preserve escaped %% in GROUP BY params (#537, closes #476)

• What changed: GROUP BY queries mixing escaped %% literals with real params no longer raise IndexError; placeholder rewriting now only touches %% and %s.
• Who benefits: Anyone running raw/annotated GROUP BY queries with escaped percent literals.
• Impact: Those queries run correctly instead of erroring (also fixes one Query results different on 1.5 on static query. #394 case of silently wrong rows).

FIX: Support IntegerChoices params in raw GROUP BY queries (#541, closes #540)

• What changed: Passing an IntegerChoices value into a raw GROUP BY query no longer raises NotImplementedError; type checks now use isinstance.
• Who benefits: Anyone passing enum choices as params into raw GROUP BY queries.
• Impact: Enum choices bind correctly; bool still binds BIT, plain int unchanged.

Test Improvements

• Regression tests for the escaped-%% and unescaped-% GROUP BY paths (FIX: Preserve escaped %% in format_group_by_params to fix IndexError on GROUP BY queries #537)
• Regression test for IntegerChoices in a raw GROUP BY query (FIX: support IntegerChoices params in raw GROUP BY queries (#540) #541)
