Column Attributes Reference

##### Syntax

    array dropColumnSql(
        string $tableName,
        string $columnName
        )

## Description

The method `dropColumnSql()` creates the SQL statement necessary to drop an existing column given by `$columnName` from an existing table, given by ''$tableName'.

In order to actually create the column, the returned array must be passed to the executeSqlArray() method.

## Usage

    /*
    * Connection to DB2 database
    */
    $dict = NewDataDictionary($db);
    $sqlarray = $dict->dropColumnSql('ACT','ACTNOTES');

    print_r($sqlarray);

    /*
     * Prints
    Array
    (
        [0] => ALTER TABLE ACT DROP COLUMN ACTNOTES
    )

    */

    $dict->executeSqlArray($executeSqlArray);
