Method Detail

getTypeDeclaration   [line 118]

string getTypeDeclaration( array $field)

Obtain DBMS specific SQL code portion needed to declare an text type field to be used in statements like CREATE TABLE.
  • Return: DBMS specific SQL code portion that should be used to declare the specified field.
  • Access: public

Parameters:

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:

length 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.

default Text value to be used as default for this field.

notnull Boolean flag that indicates whether this field is constrained to not be set to null.

  • Access: public

Parameters:

string   $type

matchPattern   [line 337]

string matchPattern( array $pattern, [string $operator = null], [string $field = null])

  • Return: SQL pattern
  • Access: public

Parameters:

array   $pattern     even keys are strings, odd are patterns (% and _)
string   $operator     optional pattern operator (LIKE, ILIKE and maybe others in the future)
string   $field     optional field name that is being matched against (might be required when emulating ILIKE)

General type conversion method
  • Return: MDB2 error on failure
  • Access: protected

Parameters:

mixed   $value     refernce to a value to be converted
string   $type     specifies which type to convert to
boolean   $rtrim     [optional] when TRUE [default], apply rtrim() to text

_getIntegerDeclaration   [line 199]

string _getIntegerDeclaration( string $name, array $field)

Obtain DBMS specific SQL code portion needed to declare an integer type field to be used in statements like CREATE TABLE.

  • Access: protected

Parameters:

string   $name     name the field to be declared.
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:

unsigned Boolean flag that indicates whether the field should be declared as unsigned integer if possible.

default Integer value to be used as default for this field.

notnull Boolean flag that indicates whether this field is constrained to not be set to null.
