columnNumber is the index of a column of the result set.
compOp is a SQL comparison operator (<, >, =, !=, <=, >=).
comparand is a comparison value.
The method returns a value indicating whether the specified comparison is true for all rows of the result set.
For example, if rsx is a Java variable of type ResultSetXml:
if rsx>>allString(3, “<”, “compare value”)…
This condition is true if in the result set represented by rsx, for all rows, the value of column 3 is less than “compare value.” This is a String comparison. Similar methods can be used for other datatypes.
