Data conversion summary

Contains a row of information for each SQL statement that required data conversion. For example, if a result column has an attribute of INTEGER, but the variable the result is being returned to is DECIMAL, the data must be converted from integer to decimal. A single data conversion operation is very inexpensive, but repeated thousands or millions of times can add up. In some cases, it is a simple task to change one of the attributes so a faster direct map can be performed. In other cases, the conversion is necessary because there is no exact matching data type available.
