Thanks Igor!
I did create indexes for the SQLite DB version based on the indexes in the
MS Access DB.
Object_Texttables does have an index on Object_ID
and Object_Transactions also has an index on - Object_ID.
Just to double check, my index declarations are:
CREATE INDEX IF NOT EXISTS
"Object_TextTables_1_index" ON
"Object_TextTables" ("Object_ID");
and
CREATE INDEX IF NOT EXISTS
"Object_Transactions_2_index" ON
"Object_Transactions" ("Object_ID");
Here is the result of the explain query plan:
0|0|1|SCAN TABLE DTC_Statuses (~1000000 rows)
0|1|0|SEARCH TABLE Objects USING INTEGER PRIMARY KEY (rowid=?) (~1 rows)
0|2|6|SEARCH TABLE Object_Types USING INTEGER PRIMARY KEY (rowid=?) (~1 rows)
0|3|7|SEARCH TABLE DisplayFormats USING INTEGER PRIMARY KEY (rowid=?) (~1 rows)
0|4|2|SEARCH TABLE Object_TextTables USING INDEX Object_TextTables_1_index
(Object_ID=?) (~10 rows)
0|5|3|SEARCH TABLE Object_Transactions USING INDEX Object_Transactions_2_index
(Object_ID=?) (~10 rows)
0|6|4|SEARCH TABLE Equations USING INTEGER PRIMARY KEY (rowid=?) (~1 rows)
0|7|5|SEARCH TABLE Equation_Types USING INTEGER PRIMARY KEY (rowid=?) (~1 rows)
I appreciate the time you spending on this!
