Hello
In my database there is a table called tblImport, which is imported to
database from MS Excel. This tblImport is having some fields called
"JobNo", "Status" etc. JobNo field contains unique data where as
Status field contains data which are separated by a space. What I wish
to do is to extract a substring from "STATUS" and get the result in
the final status. In excel with nested IF I can get the result as
below

IF(ISNUMBER(SEARCH("PCNF",A3)),"PCNF",IF(ISNUMBER(SEARCH
("CNF",A3)),"CNF",IF(ISNUMBER(SEARCH("REL",A3)),"REL",IF(ISNUMBER
(SEARCH("CRTD",A3)),"CRTD"))))


STATUS FINAL_STATUS
REL PCNF NMAT PPRT PRC SETC PCNF
REL NMAT PRC SETC REL
REL CNF NMAT PRC SETC CNF
REL PRT GMPS MACM PRC SETC REL
CRTD PRC CRTD

How to do it with the help of a access query.
Thanks in advance

You can extract from a string using the Mid and InStr functions:

GetExtract: Mid(NameOfField, InStr(NameOfField, StringToFind),
Len(StringToFind))

Thank you very much for the response.
I tried like GetExtract: Mid([Status],InStr([Status],"PCNF"),Len
("PCNF")) and it will list out all "PCNF" but if the status field
doesn't have "PCNF" then the STATUS may contain "CNF" or "CRTD" or
"REL". What I wish to do is GetExtract should first look for "PCNF",
if not then "CNF" if not then "CRTD" if not then "REL". The status
field will never have PCNF CNF CRTD together.

Try this expression as a calculated field in your query. It is all on
one line, but I have split it into multiple lines for clarity.

IIF([SomeField] Like "*PCNF*","PCNF",
IIF([SomeField] Like"*CNF*","CNF",
IIF([SomeField] Like "*REL*",""REL",
IIF([SomeField] Like "*CRTD*","CRTD",,Null ))))

Insert that expression into a field "block" in your query (assumes you
are using Query design view).
