Could someone tell me the syntax for the .import command? I can't
seem to get my null values to be recognized.
First I created test1:
CREATE TABLE [test1] (
[col1] INTEGER NOT NULL,
[col2] TEXT NULL,
[col3] INTEGER NULL
)
The data for test1.csv has the following data:
col1,col2,col3

If you type '.h' you'll see the syntax of all the commands.

Why exactly is this a bad thing? When sqlite3_step returns SQLITE_DONE

A null is not the same thing as an empty string. Some things would be

Please don't do that. I have many databases with empty strings in them w

For the following, the "," is the field delimiter and '"' is the string

Hi All,
I am a newcomer to SQLite and would like to know the best way to get
data from my DBF4 database to a SQLite SQb. I need to do this because
SQLite is used by a USB Device I recently purchased. I am at hobby level
for DBF4 but have no exposure to SQLite before.
TIA
Sorry if this is a
You could try:
www.sqliteexpert.com
Data transfer wizard -> Import from ADO data source -> Microsoft OLE DB
provider for ODBC drivers -> dBase files
should do the job, though I never tried with DBF databases.

I wish, but no, the database is locked until the process that writes

Thank you for the suggestions. I had no idea this would get such a response.
Sqlite Administrator recognized my null values as zero, so that
