First, connect to your db file. As this is the first connection this will be referred as 'main'.
Then you need to attach a memory database. ATTACH DATABASE ":memory:" AS mem; Create your table definitions in memory, por example: CREATE TABLE mem.table1 (... You can get some info from: SELECT sql FROM sqlite_master WHERE type='table' Now, to you need to something like this: INSERT INTO mem.table1 SELECT * FROM main.table1; This will insert all rows from table1 of your db file to memory db. You can create any index you need on memory, but i think will not make any difference in a memory db. CREATE INDEX memory.IDX_TABLE1_NAME ON TABLE1(table1_name); Summing up: Connect to a db file, attach a memory bd, create table definition for memory bd, do INSERT INTO ....SELECT, create index.

Hi All, Can someone give me the code you use to attach a database. I have a db file with 5 Million records and have three different tables. Index is also created in it. I want to load it in memory to apply some queries for testing. Best regards, Manzoor Ilahi Tamimy
