Question

I am using the following code to update my mysql database

String sql = "update stocks set price = ?, high = ?, change = ? where SYMBOL = ?";  
PreparedStatement stmt = conn.prepareStatement(sql); 

for(int i=0;i<ing;i++)
 {   

    stmt.setString(1, price[i]); 
    stmt.setString(2, high[i]); 
    stmt.setDouble(3, changedvalue[i]); 
    stmt.setString(4, SYMBOL[i]);

    stmt.addBatch(); 
} 
stmt.executeBatch(); 

where changedvalue is a array of type double. If i remove change it executes properly. But with it it throws the following error.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘change = 0.1 where SYMBOL = ”’ at line 1
What is the issue

Answer 1

CHANGE is a reserved word in MySQL. Try quoting it:

update stocks set price = ?, high = ?, `change` = ? where SYMBOL = ?
