ERROR_BAD_QUERY_SYNTAX

ERROR_BAD_QUERY_SYNTAX means that Windows Installer rejected the SQL statement used to query an MSI database. Windows Installer SQL is a restricted database-query language, so general SQL syntax from another database engine may not be valid.

What to check

Record the exact query text and the table or view it was intended to access.
Check identifiers, quoting, field names, and supported SQL constructs against the Windows Installer database API.
Do not convert a query failure into an empty result; that can hide a package-authoring defect.
