Hi, I'd not suggest to use CLOSQLCSR set to *ENDMOD. It's a performance killer.This option closes all ODPs (Open Data Path) that are used to access the database data, each time the module will be ended. Consequently each time the module gets called the complete optimization process must be completely executed, i.e. an access plan must be built or at least validated, the optimal index must be searched and finally temporary objects that are neccessary (such as hash tables) must be created, before the data can be accessed.
When *ENDACTGRP is used instead, the optimization process is executed only the first and second time. That means the ODP gets automatically deleted after the first run, but stays open after the second. (assumed the ODP is reuseable). Beginning with the third execution the ODP will be reused without any additional optimization.
The ODP stays open, until the activation group gets closed, or overrides on the tables will be deleted, or if the library list get changed when *SysNaming is used and the tables are used unqualified.

Could be an SQL vs rpg date format. And, yes, it would be nice if it was
true that "a date is a date is a date". However take a look at adding the
following, (especially the date format option):
C/EXEC SQL
C+ Set Option
C+ Naming = *Sys,
C+ Commit = *None,
C+ UsrPrf = *User,
C+ DynUsrPrf = *User,
C+ Datfmt = *iso,
C+ CloSqlCsr = *EndMod
C/END-EXEC
This is the SQL equivalent of the H spec.

Embedded SQL newby question...
I have a file defined as:
JRSYS K1 A 8 1 8 System
JRONAM A 10 9 18 Original Object Name
JRFNAM K4 A 10 19 28 Final Object name
JRCDAT K2 L 10 29 38 Creation date (YYYYMMDD)
JRCTIM K3 T 8 39 46 Creation time (HHMMSS)
JRVOL A 10 47 56 Volume
JRSEQ P 5 0 57 59 Sequence number
JROSIZ P 15 0 60 67 Original Size
JRSSIZ P 15 0 68 75 Saved Size
JRNOTE A 50 76 125 NOTE
Here is the first record in that file:
System..................: MD400
Original Object Name....: QUDRCV1321
Final Object name.......: QUDRCV1321
Creation date (YYYYMMDD): 0001-01-01
Creation time (HHMMSS)..: 00.00.00
Volume..................: AUD001
Sequence number.........: 209
Original Size...........: 205672448
Saved Size..............: 45297664
NOTE....................:
This is my data structure:
** Data Structure for SQL Fetch
d DetailStr ds inz
d jrsys 8a
d jronam 10a
d jrfnam 10a
d jrcdat 10d
d jrctim 8t
d jrvol 10a
d jrseq 5p 0
d jrosiz 15p 0
d jrssiz 15p 0
d jrnote 50a
This is my SQL statement:
** Select records from SAVHISTORY
c/exec sql
c+ Declare DtlSelect Cursor
c+ For Select jrsys,
c+ jronam,
c+ jrfnam,
c+ jrcdat,
c+ jrctim,
c+ jrvol,
c+ jrseq,

c+ jrssiz,
c+ jrnote
c+ From $auditstg/savhistory
c+ Order by jrsys,
c+ jrcdat,
c+ jrctim,
c+ jrfnam
c/end-exec
I am getting the following CPF5035 error:
Message . . . . : Data mapping error on member SAVHISTORY.
Cause . . . . . : A data mapping error occurred on field
DbopExprKey(QdsSortedPtl(Node_11), SAVHISTORY_1.JRCDAT[3], 1) in
record
number 0, record format *FIRST, member number 1, in member SAVHISTORY
file
SAVHISTORY in library $AUDITSTG, because of error code 18. The error
codes
and their meanings follow:
18 -- There is data in a date, time, or timestamp field that is not
valid.
The following SQL0181 error follows the previous:
Message . . . . : Value in date, time, or timestamp string not valid.
Cause . . . . . : The string representation of a date, time or
timestamp
value is not in the acceptable range. JRCDAT is either the character
string
constant that is not valid or the column or host variable that
contained the
string. If the name is *N, then the value was found in an expression
specified in the statement. If the value was found in a host
variable, then
the host variable number is 4. The proper ranges for date, time, or
timestamp values are as follows:
-- The range for years is from 0001 to 9999.
-- The range for months is from 1 to 12.
-- The range for days is from 1 - 30 for April, June, September,
and
November, from 1 - 28 for February and from 1 to 31 for all other
months.
In a leap year, the range for February can be from 1 to 29.
-- The range for days in a Julian date is from 001 to 366 for a
leap year
or 001 to 365 days for all other years.
-- The range for hours is from 0 to 24. If the hour is 24, then
the other
parts of the time values must be zeros. If the time format is USA,
then the
hour cannot be greater than 12.
-- The range for minutes is from 0 to 59.
-- The range for seconds is from 0 to 59.
-- The range for microseconds is from 0 to 999999.
Recovery . . . : Ensure that the date, time, or timestamp value
conforms to
the ranges for the data type it represents. Try the request again.
I believe my issue has to do with defining the date/time field, and I
don't know what to put where to fix it.
Please direct me to a page in a manual that describes what I have done
and how to fix it. Or, if it's simple... just respond gently... :-)
Thank you,
Dave
