I am seeing the following in my trace file:
Bind#3 oacdty=01 mxl=128(35) mxlc=36 mal=00 scl=00 pre=00
oacflg=03 fl2=1000010 frm=01 csi=31 siz=0 off=168
kxsbbbfp=ffffffff79f139a8 bln=128 avl=35 flg=01 value="1234 W
1234 West, West Groves City"
I am wondering what the mxlc value is?
I quote
Bind #n
oacdty - Datatype code
mxl - Maximum length of the bind variable value (private maximum length in parentheses)
mxlc - Unknown :(
mal - array length
scl - Scale
pre - Precision
oacflg - Special flag indicating bind options
fl2 - second part of oacflg
frm - Unknown :(
csi - Unknown :(
siz - Amount of memory to be allocated for this chunk
off - Offset into this chunk for this bind buffer
kxsbbbfp- Bind address
bln - Bind buffer length
avl - actual value length
flg - bind status flag
value - Value of the bind variable
Source (& snippet of the book)
The book also quotes-
There is currently no information on three parameters.
Which are mxlc,frm, and csi.
Summary
mxlc appears to be the maximum number of characters for the bind variable, but only if the variable uses character length semantics.
Method
I searched My Oracle Support for mxlc. Almost every article has mxlc=00, the only exceptions involve an NVARCHAR or NCHAR. The code below is based on the code from Document ID 552262.1. I changed the variable sizes (99 and 123 char) around, and each time mxlc was set to the variable size if character length semantics was used.
Code
create table t1(ncol1 nvarchar2(100), col1 varchar2(100));
alter session set timed_statistics = true;
alter session set statistics_level=all;
alter session set max_dump_file_size = unlimited;
alter session set events '10046 trace name context forever,level 4';
VAR nvar1 NVARCHAR2(99)
VAR var1 VARCHAR2(123 char)
EXEC :nvar1 := 'nvarchar'
EXEC :var1 := 'varchar'
SELECT * FROM T1 WHERE ncol1 = :nvar1 and col1 = :var1;
ALTER SESSION SET EVENTS '10046 trace name context off';
Results:

oacdty=01 mxl=2000(198) mxlc=99 mal=00 scl=00 pre=00

More Questions
Normally the relationship between mxl and mxlc makes sense. For a NVARCHAR, UTF16 on my system, there will be 2 bytes per character, thus 198 and 99. My database is UTF8, a character could take up to 4 bytes. Maybe Oracle guesses the average size will be 3 bytes, thus 123 and 369. Obviously it could be more than 369, perhaps that's just the initial memory allocated, and it can grow later?
But your numbers, 36 and 35, don't make sense to me. Surely the number of bytes can never be LESS than the number of characters? Is Oracle making a bad guess, or is some client program sending in bad data?

My data consists of large numbers, I have a column say - 'amount', while using it in charts(sum of amount in Y axis) it shows something like 1.4G, I want to show them as if is billion then e.g. - 2.8B, or in millions then 80M or if it's in thousands (14,000) then simply- 14k.
I have used - if(sum(amount)/1000000000 > 1, Num(sum(amount)/1000000000, '#,###B'), Num(sum(amount)/1000000, '#,###M')) but it does not show the M or B at the end of the figure and also How to include thousand in the same code.
EDIT: Updated to include the dual() function.
This worked for me:
=dual(
if(sum(amount) < 1, Num(sum(amount), '#,##0.00'),
if(sum(amount) < 1000, Num(sum(amount), '#,##0'),
if(sum(amount) < 1000000, Num(sum(amount)/1000, '#,##0k'),
if(sum(amount) < 1000000000, Num(sum(amount)/1000000, '#,##0M'),
Num(sum(amount)/1000000000, '#,##0B')
))))
, sum(amount)
)
Here are some example outputs using this script to format it:
=sum(amount)
Formatted
2,526,163,764
3B
79,342,364
79M
5,589,255
5M
947,470
947k
583
583
0.6434
0.64
To get more decimals for any of those, like 2.53B instead of 3B, you can format them like '#,##0.00B' by adding more zeroes at the end.
Also make sure that the Number Formatting property is set to Auto or Measure expression.
I'm trying to run a for loop to make a balance table in Stata (comparing the demographics of my dataset with national-level statistics)
For this, I'm prepping my dataset and attempting to calculate the percentages/averages for some key demographics.

I'm trying to run the following loop, but in the second half of the loop, I keep getting an 'invalid syntax' error. For context, in the first half of the loop (before clearing the dataset), the code stores the average values of the variables as a macro (`var'_samplemean). Can someone help me out and mend this loop?

Thanks for sharing the snippet of data. Apart from the fact the variable unearninc_wins95 has already been renamed in your sample data, the code runs fine for me without returning an error.
That being said, the columns for your F-statistics and p-values are empty once the loop at the bottom of your code completes. As far as I can see there is no local/varlist called sample which you're attempting to call with the line foreach col of varlist sample{. This could be because you haven't included it in your code, in which case please do, or it could be because you haven't created the local/varlist sample, in which case this could well be the source of your error message.
Taking a step back, there are more efficient ways of achieving what I think you're after. For example, you can get (part of) what you want using the package stat2data (if you don't have it installed already, run ssc install stat2data from the command prompt). You can then run the following code:
stat2data fem age nonwhite hhsize parent employed savings_wins95 debt_wins95 earnedinc_wins95 unearninc_wins95 underfpl2019, saving("~/yourstats.dta") stat(count mean)
*which returns:

This is missing the empty F-statistic and p-value variables you created in your code above, but you can always add them in the same way you have with gen F=. and gen pvalue=.. The presence of these variables though indicates you want to run some tests at some point and then fill the cells with values from them. I'd offer advice on how to do this but it's not obvious to me from your code what you want to test. If you can clarify this I will try and edit this answer to include that.
This doesn't answer your question directly; as others gently point out the question is hard to answer without a reproducible example. But I have several small comments on your code which are better presented in this form.
Assuming that all the variables needed are indeed present in the dataset, I would recommend something more like this:
local myvarlist fem age nonwhite hhsize parent employed savings_wins95 debt_wins95 earnedinc_wins95 unearninc_wins95 underfpl2019
local desc `" "% Female" "Age" "% Non-white" "HH size" "% Parent" "% Employed" "Savings stock ($)" "Debt stock ($)" "Earned income last mo. ($)" "Unearned income last mo. ($)" "% Under FPL 2019" "'
local i = 1
gen variable = ""
gen mean = ""
local i = 1
foreach var of local myvars {
summ `var', meanonly
local this : word `i' of `desc'
replace variable = "`this'" in `i'
if inlist(`i', 1, 3, 5, 6, 11) {
replace mean = strofreal(100 * r(mean), "%2.0f") in `i'
}
else if `i' == 4 {
replace mean = strofreal(r(mean), "%2.1f") in `i'
}
else replace mean = strofreal(r(mean), "%2.0f") in `i'
local ++i
}
This has not been tested.
Points arising include:
Using in is preferable for what you want over testing the observation number with if.
round() is treacherous for rounding to so many decimal places. Most of the time you will get what you want, but occasionally you will get bizarre results arising from the fact that Stata works in binary, like any equivalent program. It is safer to treat rounding as a problem in string manipulation and use display formats as offering precisely what you want.
If the text you want to show is just the variable label for each variable, this code could be simplified further.
The code hints at intent to show other stuff, which is easily done compatibly with this design.
I want to calculate the end offset of a parent locator in a VHD. Here is a part of the VHD header:
Cookie: cxsparse
Data offset: 0xffffffffffffffff
Table offset: 0x2000
Header version: 0x00010000
Max table entries: 10240
Block size: 0x200000
Checksum: 4294956454
Parent Unique Id: 0x9678bf077e719640b55e40826ce5d178
Parent time stamp: 525527478
Reserved: 0
Parent Unicode name:
Parent locator 1:
- platform code: 0x57326b75
- platform_data_space: 4096
- platform_data_length: 86
- reserved: 0
- platform_data_offset: 0x1000
Parent locator 2:
- platform code: 0x57327275
- platform_data_space: 65536
- platform_data_length: 34
- reserved: 0
- platform_data_offset: 0xc000
Some definitions from the Virtual Hard Disk Image Format Specification:
"Table Offset: This field stores the absolute byte offset of the Block Allocation Table (BAT) in the file.
Platform Data Space: This field stores the number of 512-byte sectors needed to store the parent hard disk locator.
Platform Data Offset: This field stores the absolute file offset in bytes where the platform specific file locator data is stored.
Platform Data Length. This field stores the actual length of the parent hard disk locator in bytes."
Based on this the end offset of the two parent locators should be:
data offset + 512 * data space:
0x1000 + 512 * 4096 = 0x201000
0xc000 + 512 * 65536 = 0x200c000
But if one uses only data offset + data space:
0x1000 + 4096 = 0x2000 //end of parent locator 1, begin of BAT
0xc000 + 65536 = 0x1c000
This latter calculation makes much more sense: the end of the first parent locator is the beginning of the BAT (see header data above); and since the first BAT entry is 0xe7 (sector offset), this corresponds to file offset 0x1ce00 (sector offset * 512), which is OK, if the second parent locator ends at 0x1c000.
But if one uses the formula data offset + 512 * data space, he ends up having other data written in the parent locator. (But, in this example there would be no data corruption, since Platform Data Length is very small)
So is this a mistake in the specification, and the sentence
"Platform Data Space: This field stores the number of 512-byte sectors needed to store the parent hard disk locator."
should be
"Platform Data Space: This field stores the number of bytes needed to store the parent hard disk locator."?
Apparently Microsoft does not care about correcting their mistake, this being already discovered by Virtualbox developers. VHD.cpp contains the following comment:
/*
* The VHD spec states that the DataSpace field holds the number of sectors
* required to store the parent locator path.
* As it turned out VPC and Hyper-V store the amount of bytes reserved for the
* path and not the number of sectors.

The way I read this output is that I have 74,247 Microsoft.Internal.ReadLock instances on my heap. However, some of them are probably pending collection.
I want to display only those which are not pending collection.
For example, 0000000080f88e90 is the address of one of these objects and it is garbage. I know it, because:
0:000> !mroot 0000000080f88e90

As one can see, both sosex.mroot and sosex.refs indicate no one references it, plus dumping its fields reveals that it was disposed through IDisposable, so it makes sense that the object is garbage (I know that being disposed does not imply the object is garbage, but it is in this case).
Now I want to display all those instances which are not garbage. I guess I am to use the .foreach command. Something like this:
.foreach(entry {!dumpheap -type Microsoft.Internal.ReadLock -short}){.if (???) {.printf "%p\n", entry} }
My problem is that I have no idea what goes into the .if condition.
I am able to inspect the _isDisposed field like this:
0:000> dd 0000000080f88e90+10 L1
00000000`80f88ea0 00000001
But .if expects an expression and all I have is a command output. If I knew how to extract information from the command output and arrange it as an expression then I could use it as the .if condition and be good.
So, my question is this - is there a way to get the field value as an expression suitable for .if? Alternatively, is it possible to parse the command output in a way suitable for using the result as the .if condition?
I didn't have an example which uses ReadLock objects, but I tried with Strings and this is my result:
.foreach (entry {!dumpheap -short -type Microsoft.Internal.ReadLock})
{
.if (poi(${entry}+10) == 1)
{
.printf "%p\n", ${entry}
}
}
I'm using poi() to get pointer size data from the address. Also note I'm using ${entry} not entry in both, poi() and .printf. You might also like !do ${entry} inside the .if.
In one line for copy/paste:
.foreach (entry {!dumpheap -short -type Microsoft.Internal.ReadLock}) {.if (poi(${entry}+10) == 1) {.printf "%p\n", ${entry}}}
I am trying to read SAP Audit Log static and dynamic filters setting (sm19) using RFC connection.
For static filters i figured out they are stored in table rsauprof:

SLOTNO X RSAUSLOTNO NUMC 8 4 0 Audit log: Number of the recording parameter (slot)

CDATE RSAUCDATE DATS 56 8 0 Security Audit: Date when the audit profile was changed
SELVAR RSAUSELVAR RAW 64 1 0 Security audit: determining selection variant
MSGVECT RSAUMSGVEC CHAR 65 1 0 Security audit: selection vector of audit events
Field of interests is MSGVECT, but I have problems to interpret that value because it looks like a bitvector. How to convert that value into human-readable form?
For dynamic filters i didn't find any place to look for stored filter settings.
So the question is: how to read dynamic and static sap audit log filter settings from SAP?
You can check RSAU_CONFIG_SHOW report which had been introduced with 750 and API it uses.
Method GET_MSGVECT_FROM_ALV of class CL_SAL_CONFIG is probably what you seek.
