Hi,

Please advise, How do we convert to VARGRAPHIC to CHARACTER in SQL select ?

I am developing a cobol program to select records from a UDB table which has vargraphics fields.

When searched in google, ibm has provided following solution.
Code:

CALL "IGZCD2A" USING BY REFERENCE dbcs-item alpha-item
    BY CONTENT LENGTH OF dbcs-item LENGTH OF alpha-item


Is it possible to convert vargraphics to char in SQL itself, or we need to use above function ?

Or do we have an alternate method ?

Thanks
Magesh

Magesh_J,

If your database is defined as Unicode database you can use CAST function to convert that into character data. Make sure the output Chat has atleast twice the size of vargraphic column. ( This works on z/OS DB2 but not sure about UDB)

Check this link which explains in detail about the CAST function

Magesh_J,

Currently DFSORT does not have any built-in functions to convert graphical data. If your data is in plain hex, you can use TRAN function to UNHEX the data.
