the\u00a0<code>from_set<\/code>.<\/li>\n<\/ul>\n\n\n\n<p>The <code>TRANSLATE()<\/code> function returns a new string with all characters in the <code>from_set<\/code> replaced by the corresponding characters in the <code>to_set<\/code>.<\/p>\n\n\n\n<p>If the length of the <code>from_set<\/code> is greater than the length of the <code>to_set<\/code>, the <code>TRANSLATE()<\/code>\u00a0function
