1. Traversing a stringThere is no iterative operation in SQL, so you can implement this process by connecting a table that is used as a traversal pointer.1 Selectsubstr (E.ename, Iter.pos,1) asC2 from(SelectEname fromEmpwhereEname= 'KING') E,3(SelectId asPos fromT10) ITER4 whereIter.posLength (e.ename);There are 10 data in T10, ID from 1-10.The FROM clause provides a Cartesian product, and the resulting table resemblesThe WHERE clause restricts the POS range. SQL

1, String propertyView the systems that have those character sets:If you need to store from multiple languages into the same column, you will consider the Unicode character set (UTF8 or UCS2), only it can represent multiple language charactersSome character sets support multibyte, some contain only one byte, and the method to determine if multibyte is supported is to determine if there are multiple bytes in the string by comparing the return values of length () H and Char_length functions. For e

iterate or serialize the dictionary. Solution: using the Ordereddict class in the collections module1.8 operation of the dictionary:Questions: How do I perform some computational operations (such as minimum, maximum, sort, etc.) in a data dictionary? Solution: to perform a calculation on a dictionary value, you typically need to use the zip () function to reverse the key and value first, and then combine the max (), Min (), and sorted () methods to i

Title DescriptionGiven a sorted list, delete all nodes that contain duplicate numbers, leaving only the numbers in the original linked list that do not recur.Example 1:input: 1->2->3->3->4->4->5 output: 1->2->5Example 2:input: 1->1->1->2->3 output: 2->3Thinking of solving problemsBecause the duplicate nodes to all delete, so delete the first node to save the duplicate node, note that the special case is the beginning of the list is a repeating node, s

The latter is better to do, from the coordinate map to see the direct r=mid can.The former will have a problem when a[mid]==a[r], it is not possible to determine the median position on the polyline, at this time degenerate into a linear search, so that l++. So the worst case scenario for this algorithm
