I am using sdeexport command to export my feature class from MS SQL Server 2012. I am sure that the table is existing and connection is correct.
C:\Windows\system32>sdeexport -o create -t my_db.dbo.my_feature -f my_feature -s DB1 -D DEV -u sa -p "password"
ArcSDE 10.2
SDEX File Export Administration Utility
-----------------------------------------------------
Exporting ArcSDE object to "my_feature" in SDEX export format ...
SDE Code (-162)= Invalid database name
Unable to get permissions info on table "my_db.dbo.my_feature"
0 features converted.
0 features exported.
And also, I found the following log in sde_esri_sde,log
C:\Users\ADMINI~1\AppData\Local\Temp\2\arcE506: No such file or directory
[Mon Sep 22 17:39:32 2014] [0] [AFCD-BDS-GD1] WARNING: SDETMP: Setting temp path to c:\temp
I was wondering if someone could help me with this problem, thanks!
