Getting SQLSTATE:22001(Message : [Microsoft][SQL Server Native Client 11.0]String data, right truncation) in SQL Server 2012 but in SQL server 2008 R2.

Question

I have an application which connects to SQL through ODBC 11.
ODBC statement is :
SELECT PID
FROM PENTITY PENTITY01 WHERE ((NUM1 NOT BETWEEN ? + 10.7895 AND ? + 200.6734 AND NUM2 NOT IN (5996/ 8, ? - 89.3892, ? + 80.7543))
and the SQLBindparameter statement is :
static UCHAR num1[12]=12.589
rc = SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_CHAR, sqlType, precision, scale,
&num1, sizeof(num1), NULL);
With this SQLBindparameter statement I am getting error, It is working without any error if I change the value to 12.
The same code is working when connecting to SQL server 2008.
Thanks in advance.

Hi Nalsr,
From my research, I found:
"[Microsoft][ODBC SQL Server Driver]String
data right truncation" error may be returned from a call to
SQLBindParameter if the size of the string parameter being used is greater than the size of the column being compared to. In other words if the
string size of the <expression> to the left of the <comparison_operator> is less than the
string size of the <expression> to the
right, ODBC may return this error.
The resolution is to make the string size of the <expression> to the
right of the <comparison_operator> less than or equal to the
string size of the <expression> on the left.
It is difficult to track down this type of problem when third party development applications are being used. ODBC Trace can be used to help determine if this problem is occuring.
Here is an example where the customer has submitted a query "select count(*) from type1 where type1 = ?", type1 is varchar(5) and the
data type being passed by the application is char[9].
Here is the relevant portion of the trace. The following information from the "exit" of SQLDescribeParam
SWORD * 0x0095e898 (12)
UDWORD * 0x0095e880 (5)
Maps to the following with the actual value in parenthesis - SQL_VARCHAR Size 5:
SQLSMALLINT *DataTypePtr
SQLUINTEGER *ParameterSizePtr
The "exit" value from SQLBindParameter provides the following
information:
SWORD 1 <SQL_PARAM_INPUT>
SWORD 1 <SQL_C_CHAR>
SQL Data Type SWORD 12 <SQL_VARCHAR>
Parameter Size UDWORD 5
SWORD 0
Value PTR 0x0181c188
Value Buffer Size SDWORD 5
String Length SDWORD * 0x0181c103 (9)
The string length parameter is the length of the
string being bound to the parameter, in this instance there is a size mismatch which results in the SQLError and the SQLErrorW with the message "[Microsoft][ODBC SQL Server
Driver]String data
right truncation" .
Hope this could be helpful.
