A special function GetValueFromStructKey of the PxWebQuery component



GetValueFromStructKey function is used to load the column values, if we know the key value that defines the line of the output value of the data structure, which was generated through a connected parameter AddParamKey or AddParamWebQuery.

A special GetValueFromStructKey function in PxWebQuery component can be used when the component PxWebQuery is open through the Open() command, and there are data stretched from the database.

Description of the function GetValueFromStructKey parameters:
C# syntax:

public string GetValueFromStructKey(string FieldName, string FieldNameIn, string ValueIn, string FieldNameOut);


Description of the parameters:

FieldName - name of the column in the table of PxWebQuery component, for which we imposed the AddParamKey parameter or AddParamWebQuery
FieldNameIn - name of the column in the table of the structure by which we find a row with a return value
ValueIn - the value that we find in the column FieldNameIn by which we find a row with a return value
FieldNameOut - the value of this column from searched row. It is a return value of the GetValuFromStructKey function.
Return - if the row with the ValueIn in the column FieldNameIn is not found, the return value is String.Empty. If this row is found, the function returns the value from the FieldNameOut column of the found row.

Briefly, the GetValueFromStructKey function is used to load a value from  the table of the PxWebQuery component structure created through the parameters AddParamKey or AddParamWebQuery, if we know the key of the table and the unique value of this key, which defines a line with an output value.
