How to check if a value is a number in SQLite

Question

I have a column that contains numbers and other string values (like \"?\", \"???\", etc.)

Is it possible to add an \"is number\" condition to the where clause in SQL

Answer 1

From the documentation,

The typeof(X) function returns a string that indicates the datatype of the expression X: "null", "integer", "real", "text", or "blob".

You can use where typeof(mycolumn) = "integer"
