* Obtain DBMS specific SQL code portion needed to declare an text type
* field to be used in statements like CREATE TABLE.
* @param array $field associative array with the name of the properties
* of the field being declared as array indexes. Currently, the types
* of supported field properties are as follows:
* Integer value that determines the maximum length of the text
* field. If this argument is missing the field should be
* declared to have the longest length allowed by the DBMS.
* Text value to be used as default for this field.
* Boolean flag that indicates whether this field is constrained
* @return string DBMS specific SQL code portion that should be used to
* declare the specified field.
