Inaccurate conditions of judgment cause low efficiency
In ctosqlconv.cpp, the code below :
if( !(((SQLDataType == SQLTYPECODE_NUMERIC) && (targetPrecision > 18)) ||
((SQLDataType == SQLTYPECODE_NUMERIC_UNSIGNED) && (targetPrecision > 9))))
Only when the column is NUMERIC(19+,n), the code will skip.
It is only used for numeirc but now the other data type such as char will
do the same process.
