Long aliases are generated in WHERE clause
------------------------------------------
Key: DNET-877
URL: http://tracker.firebirdsql.org/browse/DNET-877
Project: .NET Data provider
Issue Type: Bug
Components: Entity Framework Core
Affects Versions: 6.6.0.0
Reporter: Pavel
Assignee: Jiri Cincura
When access to condition column passes through several tables, for the joined tables generated a very long alias.
And I get FirebirdSql.Data.FirebirdClient.FbException: "Dynamic SQL Error Name longer than database column size"
Example
class Table1
{
int id
int value
int idTable2
[ForeignKey("idTable2")]
Table2 table2
}
class Table2
{
int id
int idTable3
[ForeignKey("idTable3")]
Table3 table3
}
class Table3
{
int id
bool condition
}
When i do:
var result = Table1.where(t => t.table2.table3.condition).select(t => value)
generates query:
SELECT
"t"." value"
FROM
Table1 AS "t"
LEFT JOIN Table2 AS "t.Table2" ON "t"."idTable2" = "t.Table2"."id"
LEFT JOIN Table3 AS "t.Table2.Table3" ON "t.Table2"."IdTable3" = "t.Table2.Table3"."id"
WHERE
"t.Table2.Table3"."condition"
