Use a query to split a table field into two fields based on delimiter or lack thereof

[zdjbel]

Hello,



I need help with using a query to split a table field into two fields. Some of the entries have a "-" delimiter while others don't. I need those that don't have the delimiter to stay intact and the ones that do have it to move them to a new field and delete the delimiter "-".

Initial state		Desired result
OrderNumber		OrderNumber	Modification
19RB1018S0009	split to:	19RB1018S0009
19RB1018S0006	split to:	19RB1018S0006
19RB1018P0013	split to:	19RB1018P0013
19RB1018S0010	split to:	19RB1018S0010
19RB1018F0001	split to:	19RB1018F0001
19RB1018P0037	split to:	19RB1018P0037
19RB1018S0011	split to:	19RB1018S0011
SRB10017L1126-M001	split to:	SRB10017L1126	M001
SRB10015V0306-M001	split to:	SRB10015V0306	M001
19RB1018S0012	split to:	19RB1018S0012

Thank you in advance.

Use the Split function.
However you cannot use Split directly in a query, but will need to create a wrapper function.
Once created, you use it again and again.

Create a Select query first to make sure you have it working correctly.

Thank you for your suggestion. I tried making a public function and calling it from the query. Works fine on extracting the Order number itself but when I add the Modification field to the query and call the function, the database goes into debugging mode and freezes up completely. Here's what I have:

Public Function MySplit(TextString As String, ItemNumber As Long) As String


MySplit = Split(TextString,"-")(ItemNumber)


End Function


Query Field 1: Order:MySplit(OrderNumber,0)
Query Field 2: Order:MySplit(OrderNumber,1)


I understand that it freezes because there isn't a second delimiter "-" in the string being queried (or so I think), but I don't know how to "tell it" to ignore the fact that there isn't a delimiter at the end of the string so give me just the characters after the delimiter. Any suggestions?

Thank you.

You could also do it with the instr function in a query:

SELECT test.OrderNumber,
IIf( InStr(1,OrderNumber,"-") > 0 , Left([OrderNumber], InStr(1,OrderNumber,"-")-1),OrderNumber) AS NewOrdNo,
IIf( InStr(1,OrderNumber,"-") > 0 , Mid([OrderNumber], InStr(1,OrderNumber,"-")+1),Null) as Modification
FROM test;

Gives you

OrderNumber	NewOrdNo	Modification
19RB1018S0009	19RB1018S0009
19RB1018S0006	19RB1018S0006
19RB1018P0013	19RB1018P0013
19RB1018S0010	19RB1018S0010
19RB1018F0001	19RB1018F0001
19RB1018P0037	19RB1018P0037
19RB1018S0011	19RB1018S0011
SRB10017L1126-M001	SRB10017L1126	M001
SRB10015V0306-M001	SRB10015V0306	M001
19RB1018S0012	19RB1018S0012

You would need to test how many in the array?
Perhaps the Instr is better for you.

Thank you Minty, that did the trick. I'm only an occasional Access user and I would never have come up with this on my own. Thanks a million!

Hello Welshgasman,

Minty's Instr code worked and is indeed better (easier) for me as you suggested. Thank you for your efforts to help me with this.
