–DECODE 函数 CASE expr WHEN comparison_expr1 THEN return_expr1 [WHEN comparison_expr2 THEN return_expr2 WHEN comparison_exprn THEN return_exprn ELSE else_expr] END 使用case表达式,实现IF-THEN-ELSE 的示例: 1、把job_id 为it_
If both arguments in a comparison operation are strings, they are compared as strings. If both arguments are integers, they are compared as integers. Hexadecimal values are treated as binary strings if not compared to a number. If one of the arguments is aTIMESTAMPorDATETIMEcolumn and the oth...

Compare MySQL Timestamp Dates With the Date Parameter OnlyTo compare MySQL timestamp dates with the date parameter only, we create a table named date_comparison with two attributes, ID and COL_DATETIME. Here, ID is of int type and COL_DATETIME is of TIMESTAMP....
For example, in comparison of DATE and DATETIME values, the DATE value is coerced to the DATETIME type by adding a time part of '00:00:00'. To perform the comparison by ignoring the time part of the DATETIME value instead, use the CAST() function in the following way: ...
Use comparison operators like >= and <= overBETWEEN. WhileBETWEENis great for integers, it can create some date ambiguity, especially for close-range data. Comparison operators have an inclusive nature and give you more control as you can specify the exact range you’re interested in down to...
