My table holds values like 000.004.000, 000.02.000, 000.024.000. What is the best/easiest way to get 4H, 2H, or 24H respectively?

Got lazy and used DelimitedSplit8K

SELECT TextTime , ca.Item , ca.ItemNumber FROM (SELECT '000.004.000' AS TextTime UNION ALL SELECT '000.02.000' UNION ALL SELECT '000.024.000') x CROSS APPLY Scratchpad.dbo.DelimitedSplit8K(x.TextTime,'.') ca WHERE ca.ItemNumber = 2;

Another method, slightly more efficient
😎
WITH SAMPLE_DATA(TSTR) AS ( SELECT '000.004.000' UNION ALL SELECT '000.02.000' UNION ALL SELECT '000.024.000' ) SELECT SD.TSTR ,CONVERT(INT,REPLACE(REPLACE(SD.TSTR,'000.',''),'.000',''),0) AS NUM_HOURS FROM SAMPLE_DATA SD;

Output
TSTR NUM_HOURS ----------- ----------- 000.004.000 4 000.02.000 2 000.024.000 24

Thanx but, I was hoping for something I can use as a field value.

Now you have to explain exactly what you want!

You should have said that in the first place. "Use as a field value" how? How about an example? "I have X, I need Y, so I can do Z with it"?

The OP will have to explain why 024 = 24 and 02 = 2 and not 20

If the data always has 3 parts separated by periods as you've indicated above, then this is simple...

SELECT PARSENAME(TextTime,2)+'H'
FROM dbo.YourTable

;

Nice. I'll use replace(PARSENAME(TextTime,2)+'H','0','') to remove the leading zero's but, this is perfect.

No... do no use REPLACE here because it will change things like 020 to just 2. Convert to an INT and then back to character based to add the "H".

No... do no use REPLACE here because it will change things like 020 to just 2. Convert to an INT and then back to character based to add the "H".

Or use the CONCAT function...
DECLARE @TextTime VARCHAR(11) = '000.002.000';

SELECT CONCAT(CONVERT(INT, PARSENAME(@TextTime, 2)), 'H');

Damn. I hate what MS does behind the scenes on these supposed improvements. Here's what PARSNAME and CONCAT renders out to. I'd forgotten that PARSNAME produces an NVARCHAR result.

[Expr1093] = Scalar Operator(concat(CONVERT_IMPLICIT(varchar(12),CONVERT(int,parsename(CONVERT_IMPLICIT(nvarchar(11),[@TextTime],0),(2)),0),0),'H'))
