I wanted to use foreign key mechanism for database. But, the tables are not following the integrity constraints. How can I be sure that, my sqlite3 db has Foreign key support ?

Type the command “PRAGMA foreign_keys” in the sqlite3 prompt and if returns no data instead of a single row containing “0” or “1”, then the version of SQLite you are using does not support foreign keys (either because it is older than 3.6.19 or because it was compiled with SQLITE_OMIT_FOREIGN_KEY or SQLITE_OMIT_TRIGGER defined)
