DREAMWEAVER API REFERENCE

The database API

Last updated 8/27/2013

Returns

An array of objects, one object for each column. Each object defines the following three properties for the column with

which it is associated.

Example

The following example uses MMDB.getColumns() to set the tooltip text value:

var columnNameObjs = MMDB.getColumns(connName,tableName);

var databaseType = MMDB.getDatabaseType(connName);

for (i = 0; i < columnNameObjs.length; i++)

{

var columnObj = columnNameObjs[i];

var columnName = columnObj.name;

var typename = columnObj.datatype;

if (dwscripts.isNumber(typename))

{

// it already is a num

typename = dwscripts.getDBColumnTypeAsString(typename, databaseType);

}

var tooltiptext = typename;

}

MMDB.getColumnsOfTable()
