More Information

The following C++ code snippet demonstrates how to reproduce this issue by using the ODBC API:
 
// hdbc is an ODBC HDBC handle opened to SQL Server ODBC driver.
// Typical error handling is left out for brevity.
rc = SQLAllocStmt( hdbc, &hstmt );

// Drop and re-create stored proc.
rc = SQLExecDirect( hstmt, (SQLCHAR*) "drop procedure sp_SQLRepro", SQL_NTS );
rc = SQLExecDirect( hstmt, (SQLCHAR*)"create procedure sp_SQLRepro(@p1 text) as return 999", SQL_NTS );
rc = SQLFreeStmt( hstmt, SQL_CLOSE );

// Bind output parameter.
cbRetValue = sizeof(szReturnValue);
rc = SQLBindParameter( hstmt, 1, SQL_PARAM_OUTPUT,SQL_C_CHAR, 4, 0, 0, szReturnValue, 255, &cbRetValue );

// Prepare SQL statement with embedded ASCII characters.
ZeroMemory( szASCIIChars, sizeof(szASCIIChars) );
ZeroMemory( szSQL, sizeof(szSQL) );
szASCIIChars[0] = (char) 13;
szASCIIChars[1] = (char) 28;
szASCIIChars[2] = (char) 13;
sprintf( szSQL, "{ ? = call sp_SQLRepro( 'Testing...%s' ) }", szASCIIChars );
// The error message is returned when executing this statement.
rc = SQLExecDirect( hstmt, (SQLCHAR*) szSQL, SQL_NTS );
