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.

mapPrepareDatatype   [line 545]

string mapPrepareDatatype( string $type)

Maps an mdb2 datatype to native prepare type
  • Access: public

Parameters:

string   $type   —

matchPattern   [line 337]

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

build a pattern matching string
  • 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)

patternEscapeString   [line 392]

string patternEscapeString( )

build string to define escape pattern string
  • Return: define escape pattern
  • Access: public

_baseConvertResult   [line 69]

object a _baseConvertResult( mixed $value, string $type, [boolean $rtrim = true])

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.
  • Return: DBMS specific SQL code portion that should be used to declare the specified field.
  • 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.
