sqlite3 update table

You have two options. First, you could simply add a new column with the following:

ALTER TABLE {tableName} ADD COLUMN COLNew {type};

Second, and more complicatedly, but would actually put the column where you want it, would be to rename the table:

ALTER TABLE {tableName} RENAME TO TempOldTable;

Then create the new table with the missing column:

CREATE TABLE {tableName} (name TEXT, COLNew {type} DEFAULT {defaultValue}, qty INTEGER, rate REAL);

And populate it with the old data:

INSERT INTO {tableName} (name, qty, rate) SELECT name, qty, rate FROM TempOldTable;

Then delete the old table:

DROP TABLE TempOldTable;

I'd much prefer the second option, as it will allow you to completely rename everything if need be.
