The SELECT statements in the following SQL provoke a NULL pointer deference: CREATE TABLE t1(a INTEGER PRIMARY KEY); CREATE TABLE t2(b INTEGER PRIMARY KEY, x1 INT COLLATE NOCASE); CREATE TABLE t3(x2 INT); SELECT * FROM t3, t2, t1 WHERE x2=b AND x1=a AND a=1; SELECT * FROM t3, t2, t1 WHERE b=x2 AND a=x1 AND 1=a; This problem was originally reported against System.Data.SQLite at https://system.data.sqlite.org/index.html/info/dd30ecb89d423c4c. | ||||
