Resolve profile.* filter fields to known profiles columns - #460
Conversation
The profile.* branch of buildFilterWhere took the caller-supplied field name and put it straight into the generated predicate, so a name that was not a profiles column became whatever text the caller sent. The group.* and session.* branches already resolve their names and drop the filter when they cannot; profile.* now does the same, against the column set that getProfilePropertySelect lists for the SELECT side. Fragments are also parenthesized on the way out. Callers join them with AND and no grouping, so a fragment with a top-level OR (contains, gt with several values) changed how the surrounding conditions bound.

ChangesFilter SQL safety
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR restricts profile filters to known columns and groups generated predicates correctly, but the filter clauses still bypass the repository’s standard database query-construction APIs, leaving escaping and validation behavior less consistent than required. Merge should wait for that migration or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 188-197: Replace raw SQL construction in profileColumnSql and the
related set filter clause with the custom ClickHouse query builder and query
functions, while preserving PROFILE_COLUMNS allowlist validation and escaped
property-key handling. Ensure both affected filter-expression paths produce
builder expressions rather than interpolated SQL strings.

What changed
Two things in
buildFilterWhere, both inpackages/db/src/services/filter-where.service.ts.profile.*field names are now resolved, not passed through.profileColumnSqlhandledprofile.properties.<key>(escaped map lookup) and then returned the rest of the name verbatim as a column expression. Aprofile.<field>name that was not a profiles column became whatever text the caller sent, embedded in the generated predicate. Field names reach this function from saved reports, URL filter state, and direct API calls, so they are not guaranteed to be column names.It now returns
string | null, resolving only the profiles columns:id,first_name,last_name,email,avatar,created_at,last_seen_at.buildProfileClausereturnsnullwhen it does, sobuildFilterWhereomits the filter. Theproperties.<key>path is unchanged. This is how the sibling branches already work:sessionColumnSqlreturnsnulloutside its set andbuildSessionClausedrops the filter.Generated fragments are parenthesized. Callers concatenate fragments into a larger predicate with
ANDand no grouping.compileScalarClauseemits a top-levelORfor multi-valuecontains,gt,regexand friends, so such a fragment changed how the surrounding conditions bound. Wrapping at the source keeps each fragment self-contained.New unit tests in
packages/db/src/services/filter-where.test.tscover both, across all threeselfTablevalues. They are pure string assertions, no ClickHouse needed.Evidence

Each side now has a comment pointing at the other.packages/db/src/services/profile.service.ts:465andpackages/db/src/services/cohort.service.ts:649— fragments joined withAND, no grouping. Same shape atsession.service.ts:207,session.service.ts:536, andevent.service.ts:1404; the latter two go throughQueryBuilder.rawWhere, which appends withAND(packages/db/src/clickhouse/query-builder.ts:190,:666).No caller string-matches on the fragment text, so the added parentheses are safe. Every consumer either joins the values with
ANDor hands them torawWhere.What I left out
is_externalis not in the allowed set. The filter option list (packages/trpc/src/routers/chart.ts:293-299) offersprofile.id,first_name,last_name,email,created_at,last_seen_atand nothing else, so adding it would widen the surface past what the UI can produce.avataris included becausegetProfilePropertySelectlists it and the two sides are meant to match.packages/db/src/services/overview.service.tsis untouched. It checks names againstWHITELISTED_FILTERSbefore building predicates.getEventFiltersWhereClause(the chart and funnel path) is untouched. It already drops bare names outsideEVENT_TOP_LEVEL_COLUMNS.biome checkviolations in the files I touched are left alone. Baseline was 29 errors acrossfilter-where.service.tsandchart.service.ts; it is 26 after this change, purely because the repeatedif (clause) where[id] = clauselines collapsed into one helper.Checks

Unrelated to this change.tsc --noEmitinpackages/db— no errors in the touched files. The 22 remaining errors are all in other files and all present on the base commit.What to look at first
The allowed column set in
profileColumnSql. If a surface offers aprofile.<field>name that is not in it, that filter now silently disappears instead of being applied. I checked the filter option list inpackages/trpc/src/routers/chart.tsand the SELECT-side list inchart.service.ts; a saved report holding an older or hand-written name would be the thing to think about.🤖 Generated with Claude Code
