...注意: 如果所有参数均为非二进制字符串,则结果为非二进制字符串。 如果自变量中含有任一二进制字符串,则结果为一个二进制字符串。...一个数字参数被转化为与之相等的二进制字符串格式;若要避免这种情况,可使用显式类型 cast, 例如: SELECT CONCAT(CAST(int_col AS CHAR), char_col) SELECT...
How, in Javascript, can I cast a string as an array in the same way that PHP (array) does. //PHP $array = (array)"string" Basically I have a variable that can be an array or a string and, if a string, I want to make it an array using an inline command. javascript Share I...
