NATIVE_UTF16_CHARSET_NAME

public static final String NATIVE_UTF16_CHARSET_NAME

TEST_UNICODE_STRING

public static final String TEST_UNICODE_STRING

A constant string which can be used wherever a Java string containing Unicode characters is needed in a test. It spells 'anthropos' in Greek.

Constant Field Values

TEST_UNICODE_SQL_ESCAPED_LITERAL

public static final String TEST_UNICODE_SQL_ESCAPED_LITERAL

A constant string which can be used wherever a SQL literal containing Unicode escape characters is needed in a test. It spells 'anthropos' in Greek. The escape character is the SQL default (backslash); note that the backslash-doubling here is for Java only, so by the time the SQL parser gets it, there is only one backslash.

Method Detail

toStringFromByteArray

public static String toStringFromByteArray(byte[] value,
                                           int radix)

Converts a byte array into a bit string or a hex string.

For example, toStringFromByteArray(new byte[] {0xAB, 0xCD}, 16) returns ABCD.

toByteArrayFromString

public static byte[] toByteArrayFromString(String value,
                                           int radix)

Converts a string into a byte array. The inverse of toStringFromByteArray(byte[], int).

toStringFromApprox

public static String toStringFromApprox(double d,
                                        boolean isFloat)

Converts an approximate value into a string, following the SQL 2003 standard.

toBoolean

public static Boolean toBoolean(String str)

Converts a string into a boolean
