  array createTableSql (
      string $tableName,
      string $fields,
      optional array $tableOptions
      )
</WRAP>
===== Description =====
The method ''createTableSql()'' creates the SQL statement necessary to create a table in the database and populates it with columns defined in ''$fields'' option. In order to create the table, the output of the command must be executed with the [[v5:dictionary:executesqlarray|executeSqlArray()]] method.

===== Parameters =====
==== $tableName =====
The table name must not yet exist in the database. Names must conform to any database specific requirements such as length limitations and name casing.

<WRAP right tip 200px>
$fields is a string, not an array
</WRAP>
==== $fields ====
A string holding information regarding the columns to create in the new table. For a detailed description of the format of this string, see [[v5:dictionary:addcolumnsql|addColumnSql()]].
==== $tableOptions ====
An optional array of information that adds information regarding the table creation. This array may also contain field specific information, for example information pertaining to auto-increment fields. Another feature of this option is that it can be used to provide database specific options to the table itself, e.g.

<code php>

$tabname = 'TEST';
$flds    = 'column definitions....';
$opts    = array('MYSQL'=>"ENGINE INNODB,COMPRESSION 'ZLIB'",
                 'DB2'=>'TABLESPACE LARGE_SPACE');

$sql = $db->createTableSql($tabname,$flds,$opts);
</code>

In the example above, the values provided in ''$opts'' will be added to the table if the **data provider** matches that of the currently attached database.
===== Usage =====
<code php>
/*
* create a data dictionary object, using the database connection
*/
$dict = NewDataDictionary($db);

$tabname = "UCTABLE";

$flds = " 
   COL1 C(32) NOTNULL DEFAULT 'abc',
   COL2 I  DEFAULT 0,
   COL3 N(12.2)
  ";

/*
* create the SQL statement necessary to create the table and its columns
*/
$sqlarray = $dict->createTableSQL($tabname, $flds);

/*
 * This returns (for DB2)
Array
(
    [0] => CREATE TABLE UCTABLE (
           COL1         VARCHAR(32) DEFAULT 'abc' NOT NULL,
           COL2         INTEGER DEFAULT 0,
           COL3         DECIMAL(12,2)
           )
)
*/


/*
* This statement actually creates the table
*/
$dict->executeSqlArray($sqlarray);
