SQL stored procedures often need to call some functions to make the processing process more reasonable and make the function more reusable. However, you may find that when writing SQL functions, some functions are written under the table value function and some are written under the

date as an integer value. This section is specified by DatePart. DATEPART (dd, date) is equivalent to day (date) DATEPART (mm, date) equals month (date) DATEPART (yy, date) is equivalent to year (date) The following table lists the DATEPART options and the abbreviations recognized by the SQL Server Compact Edition: Date part abbreviation NBSP; Year yy, yyyy Quarterly QQ, q Month mm, m One da

cannot be successful. The difference between the three is summarized as follows: 1) Try_parse only supports character-to-value or time-type, while Try_cast and try_convert support more types; 2) There is a bit more good is the character of the white space processing, as long as the space in the split symbol before and after the "2015/09/10" This can be successfully processed, but if the space is separated by itself is a whole data value part, then all can not be recognized, like "2015/0 9/10".

There is a priority problem in the data type in SQL Server. The return result type of a scalar expression is also determined by the type of operand, such as 1 + ' 1 ' =2. Instead of ' 11 ', the precedence of some int is higher than that of the varchar type. So the result of the expression is implicitly converted to the int type.Also for
