Well you have a column named data and a table named data, but the biggest issue is you only supplied 3 column names but in the values list you have 6 values.

To: sqlite-users@sqlite.org Date: Thursday, June 4, 2009, 2:39 AM Thank you a lot! I created a table: CREATE TABLE data ( num INTEGER, di CHAR(4), data CHAR(12), time1 INTEGER, time2 INTEGER, format CHAR(1) ); and create a index: CREATE INDEX i_data ON data (num, di, time1); I want to do: first tell whether there is a record in the table "data" according to the index "i_data". to update the record if there is a record; to insert the record if there isn't any record. when I run the sql: INSERT OR REPLACE INTO data (num, di, time1) VALUES (12, '1290', '732e4a390000', 8323000, 8323255, 22); the sqlite3 report a error: SQL error: 6 values for 3 columns Does It mean the method isn't the right way?
