问题
I am developing an Application using PHP and SQLite. And I create a my table's column with BLOB data types. I want to know that does BLOB data types in SQLite supports FULL-text search?
回答1:
As I understand the documentation, the type specified is parsed, but ignored:
a datatype name may be optionally specified for each column. This is pure syntactic sugar, the supplied typenames are not used by FTS or the SQLite core for any purpose.
This suggests that all columns in the table are created as TEXT or TEXT-like columns.
(As I understand, you are supposed to move columns eligible for full-text search to a separate virtual FTSx table, and just reference them through their FTSDx rowid).
