This function is used to select a database value from the database. The corresponding database field must be the type "Date". |
|||
![]() |
If the function is called using the Where clause "actual', LogiView tries to read the table field value from the current mask. |
|||
![]() |
If the number of values which are returned by the where clause is unknown, it is absolutely necessary to call sel_value(count) and proceed with the programming depending on the result. If the result > 1 , an array must be read-in. Example: |
|||
Syntax: |
||||
{DAT_VAR}= sel_date({FLD},{WHERE|actual}) or |
||||
I/O parameters: |
||||
Return value: |
||||
|
