My project has subqueries used inside nested Query.While using a subquery inside the inner query, variable declared in outer query becomes unaccesible to inner queries inside it.
Error found while debugging nested queries:
1. Unknown column 'Join3.appcategoryid' in 'field list'
2. Unknown column 'Extent1.taxonomyid' in 'where clause'
enter code here :
public static dynamic GetTaxonomies
(int businessUnitId, int memberId, string businessUnitType)
{
using (var db = new ProtocolManagementDatabaseEntities())
{
var taxonomies = (from taxonomy in db.taxonomies
join businessUnitTaxonomy in db.businessunittaxonomies on taxonomy.taxonomyid equals businessUnitTaxonomy.taxonomyid
let TaxonomyID = taxonomy.taxonomyid
where businessUnitTaxonomy.businessunitid == businessUnitId
select new
{
TaxonomyId = taxonomy.taxonomyid,
TaxonomyName = taxonomy.taxonomyname,
preferenceValue = db.userpreferences.Where(x => x.entitycolumnvalue == TaxonomyID &&
x.memberid == memberId && x.entitytablename == "Taxonomy" && x.sequencenumber == 5)
.Select(x => x.isvisible).FirstOrDefault()
AppCategory = (from appCategory in db.appcategories
join appCategoryTaxonomy in db.appcategorytaxonomies on appCategory.appcategoryid equals appCategoryTaxonomy.appcategoryid
let AppCategoryID = appCategory.appcategoryid

None of the query returns NULL. But the error occurs when we are using the MariaDB, the query works proper for PostGres and Sql Server Database.

Are you sure the data is the same in all the database? The error is not what the title of the posting says. The error is due to the columns in the database : 1. Unknown column 'Join3.appcategoryid' in 'field list' 2. Unknown column 'Extent1.taxonomyid'
