Keyword CREATE TABLE

Create table statement.

Syntax:

    CREATE TABLE tableid;
    CREATE TABLE tableid (
        column type constraints, ...
    );

    alasql('CREATE TABLE star (�  \
                one INT DEFAULT 100, \
            �    two STRING,�\
                three BOOL PRIMARY KEY�); \
    ');
    alasql('CREATE TABLE flight (flightNo INT, fromCity STRING, toCity STRING)');

Tables without column declarations

For tables with unknown columns skip column definition part:

    alasql('CREATE TABLE one');
    alasql('INSERT INTO one VALUES {a:1}');

Columns data types

You can define data types for each column.

Also you can use columns without [data types](Data Types):

    alasql('CREATE DATABASE test252; USE test252;');
    alasql('CREATE TABLE sqlite_sequence(name,seq)');
    alasql('INSERT INTO sqlite_sequence VALUES (1,10)');
    alasql('INSERT INTO sqlite_sequence VALUES ("one","ten")');
    var res = alasql('SELECT * FROM sqlite_sequence');

returns:

    [ { "name": 1, "seq": 10 }, { "name": "one", "seq": "ten" } ]

Constraints

You can use the following types of constraints:

• AUTO_INCREMENT, AUTOINCREMENT, or IDENTITY
• CHECK
• [PRIMARY KEY](Primary Key)
• [FOREIGN KEY](Foreign Key)
