passing double values (usingsetObjectw/o a specified target type) to a batch insert causes some double values to be sentas the exact Base-10 representationwith a precision of 43 digits, instead of a valid MSSQL float type. This causes the error: "Error converting data type float to decimal...

Converting the bit data type The bit data type is used to hold a single boolean value, 0 or 1. MS SQL does not support assigning NULL to this fields. InterBase can emulate this with an INTEGER or a CHAR(1) data type. The acceptable values can be restricted using domains. For more in...
