register()
Description:
Register a .dfx/.splx file as a function to be called.
Syntax:
register(f,spl)
Note:
The function registers a script file spl as function f to call it in a cellset script. Syntax of the function expression is f(xi,...), where xi,... is a parameter in the spl file. Use the comma to separate multiple parameters.
The function name is the one registered the last time.
Parameter:
|
f |
Function name |
|
spl |
.dfx/splx file path, which can be an absolute path or a relative path; a relative path is relative to the main directory |
Return value:
Result of executing the script file
Example:
Below is emp.dfx:
|
|
A |
|
|
1 |
=connect("demo") |
|
|
2 |
=A1.query("select * from employee where DEPT=?",arg1) |
|
|
3 |
return A2 |
|
|
|
A |
|
|
1 |
=register("df1","D:/emp.dfx") |
Register emp.dfx as df1 function |
|
2 |
=df1("HR") |
Call the registered function
|
