Usage

Browse the docs and search for what you may need. The following is a CRUD example for partitioned tables.

.qtk.import.loadModule["tbl";`qtk];  // Import module tbl from package qtk

// Create the partitioned table with given data
.qtk.tbl.create[
  `:/tmp/qtk/db`date`Table;  // A partitioned table ID that specifies database directory, partition field, and table name
  ([] date:2022.01.01 2022.01.02; c1:1 2)];
.qtk.db.load `:/tmp/qtk/db;

// Double values in column c1
.qtk.tbl.update[`Table; (); 0b; (enlist`c1)!(enlist (*;`c1;2))];

// Select the whole table
.qtk.tbl.select[`Table; (); 0b; 0#`];

// Drop the table
.qtk.tbl.drop `Table;
