Java and “\u” ( blackslash u )

This article is related to escaping of “\u” backslash u [Unicode character] in Java Problem Statement: I have a string which consists of a DOS path something like "\sample\user_data\example".The “\u” (backslash u) in “\user_data” above gives “an invalid Unicode” JavaScript error in IE and hence my page isn’t displayed. I tried to replace “\u” (backslash u) in the string with something like "\ u"(backslash u) as I was not able to escape it. This also does not work . Java complier does not allow “\u” (backslash u) character and gives "Invalid unicode character sequence" error when I use it with replaceAll. Que 1: Can I escape the \u character some how in Java or JavaScript? Que 2: How can I replace all "\u" character in a string with something else like "\ u"? I have posted this query to some of the Java and JavaScript related groups. Here are the solutions I found Before going into the details about solution let us

MySQL :: tinyInt1isBit

One can enter values apart from 0 and 1 (say 2,3,?100) in a field with tinyint(1) type in MySql. MySql doesn?t complain. Now if you want to read inserted data using PHP it will return value as it is, however this will not work with Java. Java will throw an exception while reading same MySql data. Java treats tinyint(1) as Boolean and returns only true or false. Two solution either we can make our column tinyint(something > 1), or can add the connection property 'tinyInt1isBit=false' to our JDBC URL. Adding connection property 'tinyInt1isBit=false' to JDBC URL is risky since it will affect entire database data while reading the same using Java.
