You can look here - http://mybatis.github.io/mybatis-3/dynamic-sql.html
By the way, you don't need code like
<isNotNull property="statisticAccountingUnits">#statisticAccountingUnits#</isNotNull> <isNull property="statisticAccountingUnits">null</isNull>
use #{statisticAccountingUnits, jdbcType=NUMERIC}
http://mybatis.github.io/mybatis-3/sqlmap-xml.html#Parameters
The JDBC Type is required by JDBC for all nullable columns, if null is
passed as a value. You can investigate this yourself by reading the
JavaDocs for the PreparedStatement.setNull() method.
