Insert converted varchar into datetime sql

阅读更多关于 Insert converted varchar into datetime sql

问题 I need to insert a varchar in my table. The type in the table is a datetime so I need to convert it. I didn't think this would be to big of a problem however it keeps inserting 1900-01-01 00:00:00.000 instead of the date I want. When I do a select with my converted date it does show me the correct date. I'll show you the code: INSERT INTO Item (CategoryId, [Date], Content, CreatedOn) SELECT CategoryId, Convert(datetime, '28/11/2012', 103), Content, GetDate() FROM Item i JOIN Category c ON i

SELECT INTO 和 INSERT INTO SELECT 两种表复制语句

阅读更多关于 SELECT INTO 和 INSERT INTO SELECT 两种表复制语句

Insert是T-sql中常用语句，Insert INTO table(field1,field2,...) values(value1,value2,...)这种形式的在应用程序开发中必不可少。但我们在开发、测试过程中，经常会遇到需要表复制的情况，如将一个table1的数据的部分字段复制到table2中，或者将整个table1复制到table2中，这时候我们就要使用 SELECT INTO 和 INSERT INTO SELECT 表复制语句了。 1. INSERT INTO SELECT语句语句形式为： Insert into Table2(field1,field2,...) select value1,value2,... from Table1 要求目标表Table2必须存在，由于目标表Table2已经存在，所以我们除了插入源表Table1的字段外，还可以插入常量。示例如下： -- 1.创建测试表 create TABLE Table1 ( a varchar ( 10 ), b varchar ( 10 ), c varchar ( 10 ), CONSTRAINT [ PK_Table1 ] PRIMARY KEY CLUSTERED ( a ASC ) ) ON [ PRIMARY ] create TABLE Table2 ( a varchar ( 10 )

Recursive Insert via binary search

阅读更多关于 Recursive Insert via binary search

问题 I have a sorted array and want to recursively find a position for inserting an element. E.g. an array 2,4,5,6,7,8,12,35 with an insertion value of 3 and the algorithm should return the index of the position where the 3 has to be inserted (index 1). The following code works sometimes, and other times it gets stuck in an infinite loop. Eventually my brain feels like jelly and I ask for your help. This is the code: private static int insertRec(int[] a, int e, int l, int r) { int mid = l + r / 2;

Using JQuery to split a <ul> in 2

阅读更多关于 Using JQuery to split a in 2

问题 Hi I have a list of unordered elements. When clicked I would like to insert a <p> element whilst splitting the <ul> in 2. The problem being that $("</ul>"+text+"<ul class=\"test\">").insertAfter(element); seems to separate the <p> element from the <ul> elements, inserting the <p> first then the <ul> tags. I would also like to remove the opening and closing <ul> immediately before and after the .temp element so I can split the <ul> in different spot. This was the only method I could find but
