FIX: Float Data May Cause Data-Conversion Overflow in ISQL/w
PSS ID Number: Q108158 Article last modified on 10-31-1994
|The information in this article applies to:|
|- Microsoft SQL Server version 4.2|
BUG# NT: 9661 (4.2)
Certain floating point numbers are not correctly displayed by ISQL/w. For example, executing the following TRANSACT SQL statement:
(1 row(s) affected)
DB-Library: Data-conversion resulted in overflow.
This is caused by the inherent loss of precision incurred when representing float data. Certain floating point values will be converted into wide character strings which cannot be displayed by ISQL/w - - 0.0006 but will be converted to the following string 6.000000000000001e-004.
Use the TRANSACT SQL STR function when retrieving data of type FLOAT. Unless information which can only be represented as float needs to be stored, use the other available datatypes.
Microsoft has confirmed this to be a problem in Microsoft SQL Server version 4.2. This problem was corrected in SQL Server version 4.21. For more information, contact your primary support provider.
