AWK is just a glue language. Simply pipe the creation command into SQLite and capture the output.

This uses a key/value store rather than a relational database to create the table.

If we define a <code>table</code> as a named collection of columns, and we define a <code>type</code> as a mechanism for the representation of some kind of data, then:

 

insertStock=: 3 :'0#stocks=: stocks,.y'

insertStock@".;._2]0 :0

'2006-04-05'; 'BUY'; 'MSOFT'; 1000; 72.00

'2006-04-06'; 'SELL'; 'IBM'; 500; 53.00

 

declares a table and some data within that table.

And, here's an example of sorting:

 

sortBy=: [ /:"1 2 (<__)|:@,. [ }.@{~ cols

from=: cols~ {"0 _ ]

├──────────┼─────┼──────┼────┼─────┤

│2006-04-05│BUY │MSOFT │1000│72 │

 

Note that this particular example is both overly general in some senses (for example, named column handling has features not demonstrated here) and overly specific in others (for example, I did not implement sort in descending order).

{{libheader|SQLite}}

The sqlite3 database is a part of the Python standard library. It does not associate type with table columns, any cell can be of any type.

>>> conn = sqlite3.connect(':memory:')

>>> c = conn.cursor()

(u'2006-04-06', u'SELL', u'IBM', 500.0, 53.0)

(u'2006-04-05', u'BUY', u'MSOFT', 1000.0, 72.0)

 

=={{header|Racket}}==

This is the relevant part of [[Table creation/Postal addresses#Racket]] that creates the DB table:

#lang racket

(require db)

(define postal (sqlite3-connect #:database "/tmp/postal.db" #:mode 'create))

However, tables (or structures) can be constructed by using stemmed arrays; &nbsp; the index would (should) be

<br>a unique identifier, &nbsp; something akin to a SSN &nbsp;(Social Security Number)&nbsp; or something similar.

 

table.id.!firstname = 'Robert'

table.id.!town = 'Gotham City'

table.id.!state = 'NY'

This code is enough to create a PStore (or open an existing PStore).

 

 

The example at [[Table creation/Postal addresses#Ruby]] puts Ruby objects into the PStore.

Run Basic supports all features of SQLite.

This is a sample of a item master

#sql execute("

CREATE TABLE item (

CREATE UNIQUE INDEX item_descr ON item( descr, itemNum);

CREATE UNIQUE INDEX item_itemNum ON item(itemNum);"

=={{header|Tcl}}==

Tables, as used in relational databases, seem far away conceptually from Tcl. However, the following code demonstrates how a table (implemented as a list of lists, the first being the header line) can be type-checked and rendered:

upvar $_tbl tbl

set heads [lindex $tbl 0]

balance 0.0 \

created 2009-05-14

Output:

<pre>

 

In practice, a binary search would be needed to find records quickly by key given that the records are being maintained in sorted order. However, for now we use a sequential search instead.

import "/fmt" for Fmt

import "/sort" for Cmp, Sort

table.removeRecord(3)

System.print("\nThe record with an id of 3 will be deleted, leaving:\n")
