Schema Loading Fails
Schema-loading failures usually come from runtime timing, unsupported configuration, or connection problems rather than the SQL text itself.
Common Causes
- Generic dialect still selected
- Unsupported schema provider
- Connection string issues
- Permissions or connectivity problems
- Runtime already frozen
What To Check
- Select a non-generic SQL Server profile first.
- Make sure loading happens before any validation.
- Confirm the connection target and credentials.
Example
QueryLens.Dialect = DialectProfile.GenericSql;
Assert.ThrowsAny<Exception>(() => QueryLens.LoadDbSchemaFrom(connectionString));
