![]() ![]() For the purposes of this article, we’re only considering FTS4 and FTS5. They share most of their code with each other, and their interfaces are the same. Customizability of FTSįTS3 and FTS4 are nearly identical. A LIKE expression works as well but is much slower. ![]() Note that it isn’t strictly necessary to use MATCH when querying an FTS table. The FTS query to the right of the MATCH operator is pretty powerful, and it should be able to accommodate all your needs. Sqlite3_bind_text(statement, 2, "PSPDFKit is a fantastic framework", 33, NULL) Sqlite3_bind_text(statement, 1, "uniqueid_2", 10, NULL) Sqlite3_bind_text(statement, 2, "Some great text", 15, NULL) Sqlite3_bind_text(statement, 1, "uniqueid_1", 10, NULL) Text length is hardcoded here, but do not do this in production! NSAssert(ret = SQLITE_OK, "Failed to create prepared statement") ![]() Ret = sqlite3_prepare_v2(db, sql, ( int)strlen(sql), &statement, NULL) Next we populate the table with some data.Ĭonst char* sql = "INSERT OR REPLACE INTO ftsTable (stringId, text) VALUES (?, ?)" NSAssert(ret = SQLITE_OK, "Failed to create table") Ret = sqlite3_exec(db, "CREATE VIRTUAL TABLE IF NOT EXISTS ftsTable USING fts5(stringId, text, tokenize='unicode61')", NULL, NULL, NULL) NSAssert(ret = SQLITE_OK, "Failed to create database connection") Int ret = sqlite3_open(.UTF8String, &db) First, we open the database connection. ![]()
