sqlite append two tables from two databases that have the exact same schema

Question

I\'m writing data into an sqlite database, but because the data set is very large, I\'m splitting the process into five pieces. As a result, I\'m writing to five different sqlit

Answer 1

You can use UNION or UNION ALL to merge 2 or more queries.

Something like:

SELECT Field1, Field2, Field3 FROM Table1
UNION 
SELECT Field1, Field2, Field3 FROM Table2

You can use an INSERT INTO NewTableName (SELECT ...) to create a new table from that UNION.

The ALL variant of the UNION clause includes the (eventual) duplicate records.
