BUG: Mapped Binary Data in ESQL-C Truncates Data After 0x00

ID: Q152112

The information in this article applies to:

SYMPTOMS

When you insert binary data into a text/image, binary or varbinary column, using dynamic ESQL-C SQL statements with variables mapped to C memory regions, the data can be truncated if it contains an embedded 0x00.


WORKAROUND

Converting the values to the ASCII equivalents and prefixing the string with "0x" (0x01020003 --> "0x01020003") will ensure all data is inserted into the column.


STATUS

Microsoft has confirmed this to be a problem in Microsoft Embedded SQL for C Programmer's Toolkit version 4.22. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

This problem does not occur with Microsoft Embedded SQL for C Programmer's Toolkit version 6.5.
