## TL;DR
Fix the statement at the position the error names, checking dialect mismatches first, because Mode sends SQL to the warehouse largely unchanged. Reserved words, date functions and quoting rules from another dialect are the most common cause. Correct the syntax, run the single query alone, and only then rerun the full report with its parameters.

```text
Mode dashboard query failed with syntax error in SQL report troubleshooting
```

## Use this when
- A Mode query fails and the error names a line or position in the statement.
- The query worked on a previous warehouse or in another BI tool and fails in Mode.
- Parameters or report filters were just added and the run started failing.

## Not for this skill when
- The query runs but the chart shows wrong numbers. That is a logic issue, not a syntax failure.
- Every query in the workspace fails at connection time. Check the data source connection first.

## Steps
1. Run the failing query alone in the Mode editor and read the full warehouse error, noting the line and position it reports. Verify: the error position lands on a real token in your statement
2. Check the tokens at that position for dialect mismatches, such as backtick quoting, a date function from another warehouse, or a reserved word used as a column name. Verify: each suspect token matches the target warehouse dialect rules
3. Quote or rename reserved identifiers, replace foreign date and string functions with the warehouse equivalents, and rerun the query. Verify: the query completes and returns rows
4. If the report uses parameters, run once with the default parameter values and once with a viewer supplied value to expose quoting problems in the parameter substitution. Verify: both runs complete without a parse error
5. Check dependent queries in the report that read from this query result, since a column rename in the fix can break the next statement. Verify: every query in the report run completes in order
6. Save the report and run it as a viewer with the scheduled parameters applied. Verify: all charts render and the run history shows a successful execution

## Why it happens
SQL portability is partial. Each warehouse accepts a different set of functions, quoting styles and reserved words, and Mode passes the statement through rather than translating it. Reports tend to break right after a warehouse migration or when a snippet is pasted from another tool, which is why the failing token is so often a small dialect detail rather than the overall logic of the query.

Mode reports run one or more SQL queries against the connected warehouse and feed the results into charts. The editor highlights parse problems, but many dialect errors only appear at run time when the warehouse parser rejects the statement. A query copied from documentation for a different warehouse, or edited after a warehouse migration, fails even though it reads as valid SQL to the author. The error message position points at the first token the parser could not accept.

Field notes for Mode specifically. The report run history and the query level error detail are the primary evidence, and Mode support and documentation describe behaviour against the warehouse, since Mode itself stores little data. When a report fails, the same query in the warehouse native client is the fastest way to separate a Mode problem from a warehouse problem, because Mode passes the statement through. Parameter handling also differs between the editor run and the scheduled or shared run, so a report should always be tested in the mode its audience actually uses before an incident is closed.

Mode teams get the most reliability from treating shared reports as reviewed code. Keeping the important report SQL in version control, even informally, means a breaking edit can be diffed and reverted instead of reconstructed from memory. It also makes warehouse migrations survivable, because the dialect differences across the estate become a searchable text problem. A short checklist for report changes, run standalone, run with audience parameters, check one downstream chart, catches most of the failures that otherwise reach viewers first.
## Variants and edge cases
### Mode Analytics SQL syntax error near position fix
The position-specific phrasing from the warehouse error.
### Mode report query failed after warehouse migration dialect
The migration variant where copied SQL stops parsing.
### Mode parameter query syntax error quoting fix
The parameter variant where substitution breaks the statement.
