SQL compilation errors in Hightouch usually come from your warehouse when Hightouch runs a query to preview a model, compute an audience, evaluate journey logic, or execute a sync. In most cases, Hightouch is surfacing the warehouse’s error message directly.

​
Where these errors appear

You may see SQL compilation errors in:
  • Model preview and model edits
  • Customer Studio audience preview or count calculations
  • Customer Studio journeys that evaluate audience/event conditions
  • Sync run failures

​
Quick checklist

When you hit a SQL compilation error:
  1. Copy the full error message and note object names, column names, and line/position details.
  2. Run the same SQL in your warehouse using the same role/context as Hightouch.
  3. Classify the error pattern below.
  4. Fix the issue at the right layer (warehouse object/permissions vs model/filter/mapping config).
  5. Re-run model preview, then re-run the audience/journey/sync flow.

​
Common error patterns

​
Invalid identifier (including _ht_to_filter)

Example patterns:
  • SQL compilation error: invalid identifier ...
  • invalid identifier '"_ht_to_filter"."COLUMN_NAME"'
What it means:
  • A referenced column is missing from the query result Hightouch is filtering or mapping.
Common causes:
  • Column renamed or removed in model SQL.
  • Audience filter, trait, journey condition, or sync mapping still references old column.
How to fix:
  1. Confirm the column still exists in model output.
  2. Update filters/conditions/mappings that reference the old name.
  3. Preview and re-save the model if metadata is stale.

​
Unresolved column with suggestions

Example pattern:
  • [UNRESOLVED_COLUMN.WITH_SUGGESTION] ... cannot be resolved. Did you mean ...
What it means:
  • A referenced column name does not exist in the active query output.
Common causes:
  • Typo in a field name.
  • Renamed/removed model column (for example after changing from SELECT * to an explicit column list).
  • Stale audience, trait, journey filter, or suggestion-job configuration.
How to fix:
  1. Verify the column exists in the parent model/event model output.
  2. Preview and re-save the model to refresh available columns.
  3. Update filter logic to use valid column names.

​
Ambiguous column name

Example pattern:
  • SQL compilation error: ambiguous column name 'COLUMN_NAME'
What it means:
  • The final query references a column name that exists in multiple joined sources, and the warehouse cannot infer which one you intended.
Common causes:
  • Multiple tables expose the same column name and the model output does not disambiguate with aliases.
  • Downstream filters/mappings reference a shared name after query wrapping.
How to fix:
  1. Alias ambiguous columns in model SQL (for example, a.faq_url AS faq_url_from_a, b.faq_url AS faq_url_from_b).
  2. Update filters, traits, journeys, and sync mappings to reference the intended alias.
  3. Re-run preview and dependent workflows.

​
Object does not exist or not authorized

Example pattern:
  • Object 'DB.SCHEMA.OBJECT' does not exist or not authorized
What it means:
  • Warehouse object is missing, moved, renamed, or inaccessible to the configured role.
How to fix:
  1. Verify object path (database/schema/object) is correct.
  2. Confirm the Hightouch role has required USAGE/SELECT privileges.
  3. Update model SQL or restore the object.

​
View definition column mismatch

Example pattern:
  • View definition ... declared N column(s), but view query produces M column(s)
What it means:
  • The warehouse view definition is out of sync with the underlying query.
How to fix:
  1. Recreate or repair the view in the warehouse.
  2. Prefer explicit column lists over SELECT * in long-lived views.
  3. Re-test the view in warehouse SQL before re-running in Hightouch.

​
Invalid data type for predicate / row comparison

Example pattern:
  • Invalid data type ... for predicate [ROW(...)]
What it means:
  • Filter predicates compare incompatible data types.
How to fix:
  1. Inspect predicate/filter logic for mixed types.
  2. Align types with explicit CAST(...) where needed.
  3. Re-test in warehouse, then in Hightouch.

​
Works in warehouse UI but fails in Hightouch

What to check:
  • Role differences between your user and Hightouch connection.
  • Different default database/schema/warehouse context.
  • Model points to a different object/version than expected.
  • SQL succeeds in UI context but fails under Hightouch role with a standard pattern above.
How to fix:
  1. Re-run under the same role/context as Hightouch.
  2. Use fully qualified names (DATABASE.SCHEMA.OBJECT) in SQL.
  3. Confirm Hightouch model references the intended object.
