```sql

CREATE TABLE `T` (

|
a TEXT,
|
|
b REAL
|
|
);
|
|
INSERT INTO T VALUES ('' || ('a'),power(100.0, 100.0)), ('b',-200.5), ('c',9e999);
|
|
CREATE TABLE "t1"(a INTEGER PRIMARY KEY, b TEXT, c INT, d INT);
|
|
INSERT INTO t1 VALUES (1, 'Wernher', 10, 100);
|
|
INSERT INTO t1 VALUES (2, 'von', 20, 200);
|
|
