title: What is the equivalent of T-SQL ISNUMERIC function in HANA Sqlscript?
body: <p>I have a requirement where I need to convert all SQL Server stored procedures into HANA stored procedures. I have come across a function ISNUMERIC in T-SQL and I am not getting the equivalent of it in HANA.</p>
  
  <p>After searching the web, I found that HANA does not have built in ISNUMERIC equivalent function. Then I tried writing my own function to achieve this and there I stuck with error handling and regular expression limitations.</p>
  
  <p>My HANA version is 70.</p>
