Detailed Description

SQLite interface stack.

Holds a defined number (COUNT_DB) of SQLite slots (with dbids) to facilitate usage of multiple parallel databases. Each database can be accessed by its dbid (database ID) as first optional parameter to mksqlite:

dbid_1 = mksqlite( 1, 'open', 'first.db' );    // open 1st database with dbid=1
dbid_2 = mksqlite( 2, 'open', 'second.db' );   // open 2nd database with dbid=2
assert( dbid_1 == 1 && dbid_2 == 2 );
query = mksqlite( 2, 'SELECT * FROM table' );  // access to 2nd database
mksqlite( 0, 'close' );                        // closes all databases
