## Minimized query
|
|
|
|
```sql

|
|
PRAGMA synchronous = '1';
|
|
.stats on
|
|
CREATE TABLE map_integer (id INT, name);
|
|
INSERT INTO map_integer VALUES(NULL,'a');
|
|
CREATE TABLE map_text (id TEXT, name);
|
|
INSERT INTO map_text VALUES('4','e');
|
|
CREATE TABLE data (id TEXT, name);
|
|
INSERT INTO data VALUES(2147483648,'abc');
|
|
INSERT INTO data VALUES('4','xyz');

CREATE VIEW idmap as SELECT * FROM map_integer UNION SELECT * FROM map_text;
