Java – use select where where Mysql to be case sensitive in MySQL
•
Java
Hi, I'm using java front end and MySQL backend,
Actually in TBL_ Test contains
name value --------------- abc 22 xyz 14 ABC 32 xyZ 4 ABc 4
In Java, I tried to retrieve the value of ABC, so I wrote a code
ResultSet result=stmt.executeQuery("select value from tbl_test where name='abc'"); while(result.next()) { System.out.println("Answer : "+result.getInt(1)); } result.close();
The current output is
Answer : 22 Answer : 32 Answer : 4
In fact, I just hope the result 'ABC' is the answer: 22
I also found the result. The code is as follows
String name="abc"; ResultSet result=stmt.executeQuery("select name,value from tbl_test where name='"+name+"'"); while(result.next()) { if(name.equals(result.getString(1)) System.out.println("Answer : "+result.getInt(2)); } result.close();
Now I get the correct output, but the result comes from Java code and is not in the query. Is it possible to retrieve the same result in the query
thank you
Solution
Use the MySQL binary operator:
select value from tbl_test where CAST(name AS BINARY) ='abc';
