Question

I am inserting a row using ibatis and a java webapp. The POJO has a field which needs to store a number (like 3.0 or 2.34). I have tried using BigDecimal and Double on the java side. On the MySQL side, I am using a Decimal(5, 5) data type.

When I try to insert a row which has “4” as the value for this numeric field, MySQL and iBatis throw the following exception:

org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation: encountered SQLException [  
--- The error occurred in org/mySQL.xml.  
--- The error occurred while applying a result map.  
--- Check the mySQL.insertQuery.  
--- The error happened while setting a property on the result object.  
--- Cause: java.lang.RuntimeException: org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation: encountered SQLException [

Am I using the wrong java data type for the value to be inserted? If not, why won’t MySQL let me insert the value?

Answer 1

You appear to have misunderstood how defining a DECIMAL (or potentially NUMERIC) column works in SQL –
Specifically, when defining the column as DECIMAL(x, y), x is the total number of digits the column will store, and y is the number of digits after the decimal point. So, in your column definition, you specified a range of -1 < column < 1. The datatype is correct, but you’re attempting to specify a value outside the range the column was told to allow.
Fortunately, the fix is simple: change the column definition. I’m assuming you want to have up to 5 digits before the decimal point, which would make the column definition DECIMAL(10, 5).
