Description:
This is used to complete the macro replacement operation.
Syntax:
${macroExp}
Note:
The macro here is taken as an expression to be computed, the result must be a string, which will replace the ${macroExp}.
The macro enclosed in quotation marks or populated in the constant cell will not be replaced.
Parameter:
macroExp |
A macro expression. |
Return value:
String
Example:
|
A |
|
1 |
="1" |
|
2 |
=${A1}+3 |
After replacing, the expression becomes =1+3 and the return value is 4. |
3 |
="${A1}+3" |
Macro is enclosed in quotation marks, so it will not be replaced, and the return value is still "${A1}+3". |
=demo.query("select * from EMPLOYEE limit 5") |
|
|
5 |
=A4.(age(~.HIREDATE)) |
Find ages of the first 5 employees. |
6 |
=A4.(${age(A4.~.HIREDATE)}+5) |
Characters in a macro will be replaced only when the expression is first parsed; a macro can’t be parsed repeatedly. |
