flash.data.SQLCollationType (Flex 3)

Pacote	flash.data
Classe	public class SQLCollationType
Herança	SQLCollationType Object

This class contains the constants that represent the possible values for the defaultCollationType parameter of the SQLColumnSchema constructor, as well as the SQLColumnSchema.defaultCollationType property.

These values represent different collation sequences that can be specified for a column in a database table. A collation sequence is a way of sorting and comparing data, for exemplo whether the database differentiates between upper and lower case characters.

For more information about defining and using collation sequences, see the section titled COLLATE in the appendix SQL support in local databases.

Detalhes da constante

BINARY

Constante

public static const BINARY:String = "binary"

Indicates that the column is defined to use the BINARY collation sequence. A SQLCollationType.BINARY collation compares two values using their byte values, regardless of the text encoding of the characters.

When binary collation is used with values of the TEXT storage class, the database differentiates between upper and lower case characters when sorting and comparing the column's values.

NO_CASE

Constante

public static const NO_CASE:String = "noCase"

Indicates that the column is defined to use the NOCASE collation sequence. A SQLCollationType.NO_CASE collation ignores upper and lower case differences when sorting and comparing two values.
