Is It Time To Stop Using IsNumeric()?

The old system function IsNumeric() often causes exasperation to a developer who is unfamiliar with the quirks of Transact SQL. It seems to think a comma or a number with a 'D' in the midde of it is a number. Phil Factor explains that though IsNumeric has its bugs, it real vice is that it doesn't tell you which of the numeric datatypes the string parameter can be coerced into, and because it doesn't check for overflow.

It will allow the Governance and Operations team visibility into production readiness of the code, warning them of security loopholes and vulnerabilities.
