Ooops I didn't modify the MyText definition:
D MyCLOBFile S SQLTYPE(CLOB_File)
D MyText S 120A
D Start S 10I 0
D RowLen S 5I 0 inz(120)
D Index S 3U 0
D ParIFSFile S 256A Varying
D inz('/home/Hauser/MyText.csv')
*------------------------------------------------------------------------
/Free
MyCLOBFile_Name = %Trim(ParIFSFile);
MyCLOBFile_NL = %Len(%Trim(MyCLOBFile_Name));
MyCLOBFile_FO = SQFRD; //Read Only
DOU %Len(%Trim(MyText)) = *Zeros;
Start = (Index-1) * RowLen + 1;
Exec SQL Set :MyText = Substr(:MyCLOBFile, :Start, :RowLen);
If SQLCODE = 100 or SQLCODE < *Zeros
or %Len(%Trim(MyText)) = *Zeros;
Leave;
EndIf;
//Do whatever you want
EndDO;
*INLR = *ON;
Return;
/End-Free
Mit freundlichen Grüßen / Best regards

Betreff: AW: Is there a way to use SQL to read files directly of the IFS
It is possible to read IFS files directly with embedded SQL by using
LOB-files or LOB Locators.
... but a LOB-file or a LOB Locator can only be handled with SQL functions
as if it would be a character field, that means you need to split the *.csv
file into columns by yourself.
Example:
D MyCLOBFile S SQLTYPE(CLOB_File)
D MyText S 50A
D Start S 10I 0
D RowLen S 5I 0 inz(120)
D Index S 3U 0
D ParIFSFile S 256A Varying
D inz('/home/Hauser/MyText.csv')

Betreff: Is there a way to use SQL to read files directly of the IFS
I have some large files on the IFS that I create from the native database.
Periodically there is a problem with that data but it's only discovered days
later when the original data is gone but in the IFS. I could copy it back to
the data base file but it would be more convenient if we could read directly
from the IFS. The files are in a CSV format.
TIA
