I have a string like:
'SPY US 03/20/20 P45'
I want to select just the date from the string.
My current query is:
Select Ticker, SUBSTRING(Ticker, PATINDEX('%[0-9][0-9]/[0-9][0-9]/[0-9][0-9]%',o.Ticker),8) AS 'myDate' FROM TABLE
This returns: 'SPY US 03/20/20 P45', 03/20/20
I want myDate to be in datetime.
I have tried various morphs of cast and convert, but they fail, presumably because they want the format to be in YYYY-MM-DD rather than MM/DD/YY.
My "smartest" attempt to convert was this:
CONVERT(DATETIME, SUBSTRING(o.Ticker, PATINDEX('%[0-9][0-9]/[0-9][0-9]/[0-9][0-9]%',o.Ticker),8),1)
After reading style guidelines here: https://www.w3schools.com/sql/func_sqlserver_convert.asp but it still failed.
The ideal end-format for the date would be YYYY-MM-DD
Edited to add:
I have been fiddling with it and realized that I over simplied my question. The convert works if I just test it on a string, but the entire query involves several joins.
As I can understand you are looking for something like this.
You can use
string_split()
function to split string with blank space and then usetry_cast()
function to check each value whether it is adate
