How to match numbers that are present between ] and [? - sql

Question

How do I match numbers that are present between ] and [ (not [ and ])?
EDIT-1
In other words, I want to extract those rows where I have a number between ] and [.
My table looks like this...
ID1 id mycolmn
1 100 [ab-ee]43[ddhj]
2 233 [aa-33]49[kl-00]
3 344 [ss-23][wdsd]
And I should get
43
49
EDIT-1 ends
See example file here. I have a column in MyDatabase and I want to extract those rows where there are two digit numbers between ] and [.
Example [ab-ee]43[ddhj] or [aa-33]49[kl-00]
The following did not work.
SELECT * from myTable where [mycolmn] Like "*\]##\[*"

Answer 1

You can use VBA or SQL.
VBA:
Function GetCode(MyColumn As String) As String
Dim RE As New RegExp
Dim colMatches As MatchCollection
With RE
.Pattern = "\]\d\d\["
.IgnoreCase = True
.Global = False
.Multiline = False
Set colMatches = .Execute(MyColumn)
End With
If colMatches.Count > 0 Then
GetCode = Replace(Replace(colMatches(0).Value, "[", ""), "]", "")
Else
GetCode = ""
End If
End Function
And you would call it like this:
SELECT GetCode([test]) AS MyDigits
FROM test;
If you want a strait SQL solution:
SELECT Mid([test],InStr([test],"]")+1,2) AS MyDigits
FROM test;
This assumes that your numbers come after the first ]. If not, it can be modified with more IIF, INSTR, & MID functions to match your pattern. It would be ugly, but it can work.

Yo dawg I heard you like brackets so I put brackets in your brackets so you can escape your brackets
Select * FROM yourTable WHERE MAtch LIKE "*]##[ [ ]*"

Answer 3

Select Mid([MyColumn],InStr([MyColumn],"]")+1,2) AS MyDigits
FROM yourTable WHERE [MyColumn] LIKE "*]##[ [ ]*"
Please award the check if this answer suits your needs. That's how StackOverflow works.

You can try PATINDEX:
create table TestPatIndex
(
MyData varchar(100)
)
insert into TestPatIndex select '[ab-ee]43[ddhj]'
insert into TestPatIndex select '[ab-ee]XX[ddhj]'
select SUBSTRING(MyData, PATINDEX ('%][0-9][0-9][[]%', MyData ) + 1, 2)
from TestPatIndex
where isnumeric(SUBSTRING(MyData, PATINDEX ('%][0-9][0-9][[]%', MyData ) + 1, 2)) = 1
Here is a link to SQL fiddle.
Something like this should work in MS Access:
SELECT MyData AS Expr1
FROM TestPatIndex
where MyData like '*][0-9][0-9][[]*'
