About
SQLancer is an automated testing tool that finds logic bugs in database systems (rather than in the databases themselves). Logic bugs are bugs that cause a database system to compute an incorrect result for a given query and a database on which the query is executed. To that end, SQLancer semi-randomly generates databases and queries, whose results are then automatically validated. SQLancer has found hundreds of bugs in database systems such as SQLite, MySQL, DuckDB, CockroachDB, and TiDB.
