Sqlite Create new columns from column containing ;

Question

I have a database test.db with the first column containing 123456;abcdef;ghijk etc. Is it possible to split the data into its own colums?

Answer 1

You can split your rows into columns by:

create table t1 as
select substr(c1,0,instr(c1,';')) as column1, 
       substr(c1,instr(c1,';')+1,instr(c1,';')-1) as column2,
       substr(c1,instr(c1,';')+1+instr(substr(c1,instr(c1,';')+1),';')) as column3
from table_test;

where c1 is the column you are selecting from.

Answer 2

There is no built-in SQLite function that can split strings like this.

If your are using the SQLite C API or a wrapper like APSW, you could create your own function (C, APSW).

If you want to do nothing more than a one-time conversion, export/import through a text file would be the simplest solution.
