How can I get the list of a columns in a table for a SQLite database?

Question

What you're looking for is called the data dictionary. In sqlite a list of all tables can be found by querying sqlite_master table (or view?)

sqlite> create table people (first_name varchar, last_name varchar, email_address varchar);
sqlite> select * from sqlite_master;
table|people|people|2|CREATE TABLE people (first_name varchar, last_name varchar, email_address varchar)

To get column information you can use the pragma table_info(table_name) statement:

sqlite> pragma table_info(people);
0|first_name|varchar|0||0
1|last_name|varchar|0||0
2|email_address|varchar|0||0

For more information on the pragma statements, see the documentation.

Here's the simple way:

.schema <table>

The question is old but the following hasn't been mentioned yet.

Another convenient way in many cases is to turn headers on by:

sqlite> .headers on

Then,

sqlite> SELECT ... FROM table

will display a headline showing all selected fields (all if you SELECT *) at the top of the output.

Here's a SELECT statement that lists all tables and columns in the current database:

SELECT m.name as tableName, 
       p.name as columnName
FROM sqlite_master m
left outer join pragma_table_info((m.name)) p
     on m.name <> p.name
order by tableName, columnName
;
