Hi
Im trying to convert a SQL CASE statement to DAX IF . Lets say I have a column of values like:
ProjectCode |
D-IREE00215 |
BADR0022 |
A-DD1255 |
and part of the query is as follows:
CASE
WHEN LEFT(ProjectCode,4) LIKE '%[a-z]%' AND SUBSTRING(ProjectCode,5,4) LIKE '%[0-9]%'
How do I write this in DAX so that the only field returned will be BADR0022

Hi @VistaDee ,
Here are the steps you can follow:
1. Create calculated column
flag =
var _1={"A","B","C","D","E","F","G","H","I","J","K","M","L","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"}
VAR _2={0,1,2,3,4,5,6,7,8,9}
var _5=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],5,1)))
var _6=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],6,1)))
var _7=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],7,1)))
var _8=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],8,1)))
RETURN
IF(LEFT('Table'[column],1) IN _1&&MID('Table'[column],2,1) IN _1&&MID('Table'[column],3,1) IN _1&&MID('Table'[column],4,1) IN _1&&
_5 IN _2 && _6 IN _2 && _7 IN _2 &&_8 IN _2,
'Table'[column],BLANK()
)
2. Result.

Hi @VistaDee
Download sample PBIX with the following code
I understand the SQL code but could you achieve the same thing by checking that the string does not contain a - ?
To create a column n DAX this would be
Column = IF(NOT(CONTAINSSTRING('Table1'[ProjectCode], "-")),'Table1'[ProjectCode])
However this is creating a new column in your data model and that might not be what you want as a lot of the column fields will be empty.
If you want to do it a a measure use this
Measure = IF(NOT(CONTAINSSTRING(SELECTEDVALUE('Table1'[ProjectCode]), "-")),SELECTEDVALUE('Table1'[ProjectCode]))
What exactly is the end result you want? A new column? A measure? Or just some code to use elsewhere?
