Question

 delete N.* from Tbl_Nodes N, Data_Tree DT WHERE N.Part = DT.Part

for this command I am getting following error.

System.Data.SQLite.SQLiteException: SQLite error near "N": syntax error

Above command works fine for MSAccess.

Is there any alternative to use table shortcut in Sqlite?

Answer 1

The DELETE statement operates on a single table and does not use a table alias. Therefore, your FROM clause must read FROM Tbl_Nodes.

You’re probably looking for:

 delete from Tbl_Nodes WHERE Part IN (SELECT Part FROM Data_Tree)

Note that this will remove all nodes from Tbl_Nodes that have a corresponding Part value in Data_Tree but does not remove any records from Data_Tree itself.

While SQL varies somewhat among vendors, as a general principle it’s a mistake to learn SQL from MS Access and try to apply it to other products. MS Access features some very non-standard constructions.
