QL0001 Syntax Errors

Structural SQL syntax failure or syntax that is unsupported for the active dialect profile.

When It Appears

• Broken statement structure such as a missing FROM, dangling commas, unmatched parentheses, or incomplete clauses
• Dialect mode can also produce QL0001 for syntax that does not exist in the selected engine, such as TOP in SQLite

Example

var query = new SqlQuery("SELECT FROM customers");
Assert.Contains(query.Errors, issue => issue.Code == "QL0001");

Next Steps

• Reduce the query to the smallest failing statement
• Confirm the selected dialect profile if the SQL is only valid in a different engine
• Check Query Fails Validation
