------------------------------------
Brandon, good point there. Should be easier/safer to do a trim() of the
produced output from the dynamic tag as you suggest.
> Remove blanks in SQL
> --------------------
>
> Key: IBATIS-143
> URL: https://issues.apache.org/jira/browse/IBATIS-143
> Project: iBatis for Java
> Issue Type: Improvement
> Components: SQL Maps
> Environment: all
> Reporter: Steffen Legler
> Priority: Minor
>
> Dynamically built SQL-Statements include a lot of blanks when using
> conditional
> elements like <isEqual>. The database doesn't care, but for logging it would
> be
> nice to have a well written sql-statement, e.g. :
> <update id="update" parameterClass="paramClass">
> update schema.table1 set
> <isEqual property="listId" compareValue="1">
> column1 = #value#
>
> </isEqual>
> <isEqual property="listId" compareValue="2">
> column2 = #value#
>
> </isEqual>
> where id=#instanceId#
> </update>
>
> The result of a statement looks like this;
> update schema.table1 set column1 = '123'
> where id = 1000
>
> For readability it would be nice to have something like this:
> update schema.table1 set column1 = '123' where id = 1000
