SQLite IN clause fails in AOT mode with parameterized list (syntax error near "@Ids") #160

Description

@7amou3

When using SQLite with DapperAOT and passing a list of values into an IN clause, the following query fails in AOT mode:

public Task<int> RemoveRangeAsync(IEnumerable<Guid> ids, CancellationToken cancellationToken)
{
    const string sql = "DELETE FROM Users WHERE Id IN @Ids";
    return db.ExecuteAsync(sql, new { Ids = ids.Select(s => s.ToString()) }, transaction: tx);
}

Error:
SQLite Error 1: 'near "@Ids": syntax error'

However, if I disable source generation for this method using [Dapper(false)], it works as expected.

[DapperAot(false)]
public Task<int> RemoveRangeAsync(IEnumerable<Guid> ids, CancellationToken cancellationToken) { ... }

It seems like the AOT generator does not correctly expand or transform the parameter list in the IN clause for SQLite. This syntax works fine with classic Dapper (non-AOT) and also in other database engines (like SQL Server).

Environment:

  • Database: SQLite
  • DapperAOT version: 1.0.48
  • .NET version: 9
