Details

Package sqlite is meta.Metadata on top of SQLite (ncruces/go-sqlite3: pure Go, no cgo).

It mirrors what the Java plug-in sees through xerial sqlite-jdbc (reference: 3.53):

query columns have no type before execution: java.lang.Object; precision/scale from the parentheses of the declared type, display is always 2147483647;
the real types come from getColumns: the declared type is classified by substrings;
getIndexInfo ignores the unique flag: unique == indexed;
auto-increment is only for columns with AUTOINCREMENT.

Verified with MetaDump.java on internal/meta/testdata/sqlite.txt.
