(columnName, type, length) |
|
|
Creates a new column in this table. The name, type and length of the new column must be specified. For specifying the
type of the column, use the JSColumn constants. The column is not actually created in the database until this
table is synchronized with the database using the JSServer.synchronizeWithDB method.
The method returns a JSColumn instance that corresponds to the newly created column. If any error occurs and the column cannot be created, then the method
returns null. |

Sample
var server = plugins.maintenance.getServer("example_data");
if (server)
{
var table = server.createNewTable("users");
if (table)
{
var pk = table.createNewColumn("id", JSColumn.MEDIA, 16); // can also use (JSColumn.TEXT, 36) for UUIDs
pk.rowIdentifierType = JSColumn.PK_COLUMN;
pk.setFlag(JSColumn.UUID_COLUMN, true)
pk.sequenceType = JSColumn.UUID_GENERATOR
var c = table.createNewColumn("name", JSColumn.TEXT, 100);
c.allowNull = false
table.createNewColumn("age", JSColumn.INTEGER, 0);
table.createNewColumn("last_login", JSColumn.DATETIME, 0);
var result = server.synchronizeWithDB(table);
if (result) application.output("Table successfully created.");
else application.output("Table not created.");
